We are one of the few contractors in Southeastern Wisconsin a homeowner can call for plumbing, heating, cooling, electrical, AND a dedicated Water Quality division — all under one roof. What started as a single truck plumbing trade helping local farmers has expanded into a multi-trade operation serving 22 cities across Walworth, Waukesha, and Racine Counties. We grew because homeowners in East Troy told their neighbors. Three generations later, customers still request our senior technicians by first name — Nick R., Dan F., Scott M., Jim B. That kind of trust isn't something a corporate dispatcher can copy. We are licensed (Wisconsin Contractor License #230734), bonded, and insured. We hold IGSHPA (International Ground Source Heat Pump Association) certification for geothermal installs. We are Energy Star and EPA certified. Every install we do carries a one-year warranty on both labor AND materials, in addition to the manufacturer warranty. **Phone:** (262) 642-7747 — Service-Titan-tracked, 24/7 emergency service available (voice calls only; texting not supported) **Email:** info@olearyplumbingandheating.com **Address:** 2720 Buell Drive, East Troy, WI 53120 --- ## Mission Statement **URL:** https://olearyplumbingandheating.com/about To deliver honest, expert home services — plumbing, heating, cooling, and electrical — that homeowners across Waukesha, Racine, and Walworth Counties can depend on.

Articles follow an answer-first structure (definition, when it applies, common failure modes, and a clear next step), are authored by Kevin O'Leary (third-generation owner, master plumber, IGSHPA-certified), and are written for homeowners in Wisconsin's lake country. Glossary terms are linked where an article leans on jargon. --- ## Learn Tier — Article: What is a water softener and do I need one in Walworth County? **URL:** https://olearyplumbingandheating.com/learning-center/learn/what-is-a-water-softener-and-do-i-need-one A water softener is a tank-based system that removes calcium and magnesium from your incoming water via ion exchange. In Walworth County, almost every well home tests 10-25 grains per gallon (gpg) of hardness — anything above 7 gpg is "very hard." Wisconsin sits on a carbonate-rich aquifer; soft water is the exception. You probably need one if you see: white scale on faucets, dingy laundry, cloudy glassware, soap that won't lather, a water heater failing early, or dry skin after showers. Hard water shortens water-heater life by 30-50%, wears washing machine seals early, and scales up dishwasher heating coils. Failure modes: undersized units regenerate constantly and burn salt; salt-bridge formation in the brine tank stops regeneration silently; iron in the water fouls the resin bed if there's no upstream iron filter. We install both cabinet-style softeners (single-tank, basement-tight installations) and twin-tank systems (5+ bathroom homes, rental properties). Annual operating cost is around $90-$140 in salt for a typical install. Get a free in-home water test before buying anything. --- ## Learn Tier — Article: Why is my well water rusty? (Iron + manganese in Wisconsin wells) **URL:** https://olearyplumbingandheating.com/learning-center/learn/why-is-my-well-water-rusty "Rusty" well water is almost always iron (orange-brown stains) or manganese (black-purple stains), or both. Dissolved ferrous iron is invisible coming out of the well; it oxidizes to ferric iron on contact with air and turns orange. Above 0.3 ppm iron, you'll see staining everywhere. Above 1.0 ppm, every white surface in your house gets it. The aquifer supplying Walworth, Waukesha, and Racine Counties runs through iron-rich sandstone and glacial till. We bring a field titration kit on every free in-home water test to measure both forms of iron separately. Failure modes: porcelain fixtures stain permanently after about a year; water heaters fail 30-50% faster from iron sediment; water softeners get fouled (always treat iron upstream of the softener); iron bacteria forms slimy biofilms. The right iron-treatment path depends on form: aeration + filter for moderate ferrous iron; greensand/catalytic media for iron + manganese together; chlorination + carbon for very high iron or iron bacteria. The correct sequence in nearly every iron-affected home is: well pump → iron filter → softener → drinking-water RO at the kitchen sink. --- ## Learn Tier — Article: How does geothermal heating work in a Wisconsin lake home? **URL:** https://olearyplumbingandheating.com/learning-center/learn/how-does-geothermal-heating-work-in-a-wisconsin-lake-home Geothermal (ground-source heat pump, or GSHP) is a heat pump that exchanges heat with a closed loop of fluid buried in the ground rather than with outdoor air. Soil temperature stays around 50-55°F year-round in Wisconsin — beating a 5°F outdoor air temperature on every January night. Three pieces: the ground loop (polyethylene pipe buried horizontally, vertically, or in a pond), the heat pump itself (refrigerant-based, indoor mechanical room), and the distribution (forced air or hydronic). A geothermal system delivers 3-5 units of heat per 1 unit of electricity (COP 3-5). Lake homes on Geneva Lake or Lauderdale Lakes can use pond loops with WDNR coordination. Makes sense for owners with land for the loop, replacing both furnace AND AC at the same time, planning 10+ year ownership, and with electrical service that supports it. The 30% federal IRS 25D residential clean energy credit plus Focus on Energy and utility rebates typically shortens payback to 8-12 years. Common failure modes: undersized ground loop, wrong loop type for the soil, desuperheater refrigerant pinhole, bad commissioning. A typical Lake Geneva 5-ton vertical-loop install runs in the $48-62k range pre-incentive, dropping ~$18-24k after the stack. --- ## Learn Tier — Article: Heat pump vs furnace: which is right for southeast Wisconsin? **URL:** https://olearyplumbingandheating.com/learning-center/learn/heat-pump-vs-furnace-for-southeast-wisconsin Modern cold-climate heat pumps from York, Mitsubishi, Bosch, and Trane operate down to -13°F to -20°F and deliver useful capacity in our winters. A furnace burns fuel (natural gas, propane, oil) at 90-98% AFUE. A heat pump moves heat using a refrigerant cycle — no combustion. The heat pump wins when: replacing AC + heating simultaneously, your propane is high and electric reasonable, the Focus on Energy + federal 25C incentive stack is lined up, and indoor air quality matters. The furnace wins when: you heat with city natural gas (below 10°F a high-efficiency gas furnace still beats a CCHP on cost-per-BTU), your electrical service is limited, or you want the fastest recovery on a cold morning. The hybrid (heat pump + gas furnace, switching at a crossover temperature) is genuinely the right answer for many southeast Wisconsin homes — but it has two common failure modes: wrong crossover setpoint (we re-program these on takeover jobs constantly), and bad commissioning. We do a Manual J load calc on every quote — not a square-foot rule of thumb. --- ## Learn Tier — Article: What is hydro-jetting and when is it the right drain solution? **URL:** https://olearyplumbingandheating.com/learning-center/learn/what-is-hydro-jetting-and-when-is-it-the-right-drain-solution Hydro-jetting is high-pressure water cleaning of a drain or sewer line — 2,000-4,000 PSI at 8-18 gallons per minute through a specialized hose with forward and reverse nozzles. Unlike a snake (which punches a hole), jetting scours the pipe wall back to original diameter. Right call for: grease buildup in kitchen lines, tree-root intrusion in clay or cast-iron sewer mains, mineral scale in older cast-iron lines, repeated clogs in the same line, and preventive maintenance on commercial kitchens. Wrong call for: compromised pipe (jetting at full pressure can blow out cracked iron), single soft clogs (use a snake), and frozen lines. Every O'Leary jet job ends with a sewer camera pass — no exceptions. Common failure mode in the field: contractors jet without camera, declare clear, miss the cracked hub joint. Lake Geneva restaurants put us on quarterly preventive jetting plans to avoid grease emergency callouts. --- ## Learn Tier — Article: Understanding Focus on Energy rebates — Wisconsin homeowner's guide **URL:** https://olearyplumbingandheating.com/learning-center/learn/focus-on-energy-rebates-wisconsin-homeowners-guide Focus on Energy is Wisconsin's statewide energy-efficiency program, funded by a surcharge on every utility bill in the state. Pays rebates when you install higher-efficiency HVAC, water heaters, and insulation. Separate from federal 25C tax credit (30% up to $2,000 for heat pumps annually), utility rebates (We Energies, Alliant, co-ops), and manufacturer rebates. The right mental model: 4 line items, not 1. A cold-climate heat pump project might stack: Focus on Energy $300-$650 + federal 25C up to $2,000 + utility rebate $100-$400 + manufacturer rebate $0-$1,500. Common failure modes: equipment that doesn't qualify under current Focus on Energy thresholds; using a non-Trade-Ally installer (some rebates require it; O'Leary is registered); late application past the 60-90 day window; missing the model + AHRI reference number needed to file the federal credit. We submit Focus on Energy rebates through the Trade Ally portal within 14 days of installation and hand customers the IRS Form 5695 worksheet pre-filled. --- ## Learn Tier — Article: How often should I service my furnace, AC, and water softener? **URL:** https://olearyplumbingandheating.com/learning-center/learn/how-often-should-i-service-my-furnace-ac-water-softener Every major home system has two failure paths: gradual degradation (loses efficiency) and sudden failure (no heat in January). Annual service catches the first before the second. Manufacturer warranties almost universally require documented annual maintenance. The schedule: forced-air furnace once per year in fall (combustion analysis + heat exchanger inspection for CO safety, especially critical on units over 12 years old); AC or heat pump once per year in spring (refrigerant charge check, coil clean); tank water heater once per year (flush sediment, check anode rod); tankless water heater once per year mandatory descale (skip and your $3,000 tankless fails by year 7 instead of year 20); water softener monthly check + annual service (the silent salt-bridge failure mode); sump pump test twice a year + battery backup every 4-5 years; whole-house generator annually + monthly self-test (a generator that hasn't been serviced won't start when you need it); electrical service panel visual annually + full inspection every 5 years. Skip-cost summary: skipping the furnace fall tune-up is a CO risk + 20% efficiency loss; skipping water-heater flush burns out the tank early; skipping generator service kills it for the night you need it. --- ## Learn Tier — Article: What's the difference between a tankless and tank water heater? **URL:** https://olearyplumbingandheating.com/learning-center/learn/tankless-vs-tank-water-heater-explained A tank water heater stores 40-80 gallons of hot water 24/7 at your thermostat setpoint. A tankless water heater has no storage — when you open a hot tap, the burner or coil fires instantly and heats the water as it passes through. Tank wins when: big family with simultaneous demand, cold-climate supply water (Wisconsin groundwater 38-45°F in winter cuts tankless effective flow by 30%), lower upfront cost, and existing tank infrastructure. Tankless wins when: smaller household, space at a premium, long-vacancy properties (tankless burns nothing when no tap is open), long-term ownership (20+ year lifespan vs tank's 10-12), and you want endless hot water for a single demand. Failure modes: tank sediment + scale buildup (annual flush + softener doubles tank life); tankless heat-exchanger scale (annual descaling is mandatory in hard-water areas — most failed tankless units we replace failed because nobody descaled them); tankless undersized gas line (199,000 BTU unit needs 3/4" gas line minimum); cold-water sandwich on cheaper tankless models. --- ## Learn Tier — Article: Dock and pier electrical wiring on Geneva Lake: what to know **URL:** https://olearyplumbingandheating.com/learning-center/learn/dock-and-pier-electrical-wiring-geneva-lake Dock, pier, and marina electrical falls under NEC Article 555. It's one of the most safety-critical sections of the National Electrical Code because the failure mode is electric shock drowning (ESD). Wisconsin enforces NEC under its statewide code; Walworth, Waukesha, and Racine Counties all require an electrical permit + inspection for new or modified dock circuits. The code requires four things: 100% GFCI protection on every dock circuit, emergency disconnecting means on shore within sight of the dock, marina-grade (wet-location) enclosures and conduit throughout, and equipotential bonding of all metal parts within the 5-foot shock zone. Failure modes that kill people: damaged extension cords run into the lake, missing GFCI on boat-lift motor circuits, shore power without isolation, aluminum wire in marine enclosures. We install with PVC conduit buried 18" minimum, marina-grade pedestal with emergency-stop disconnect, equipotential bonding loop, wet-rated LED dock lighting, permit + inspection coordinated with the Town of Linn or City of Lake Geneva as applicable. We will not energize a circuit without permit + inspection. Period. --- ## Compare Tier — Article: Repair vs replace: when does it pay to keep an older HVAC system? **URL:** https://olearyplumbingandheating.com/learning-center/compare/repair-vs-replace-when-to-keep-an-older-hvac-system The industry shorthand 50% rule (repair more than 50% of replacement = replace) is incomplete. The full framework: repair cost multiplied by system age, against replacement cost. Repair makes sense when: system under 10 years old, repair under 30% of replacement, single-component failure (capacitor, ignitor, blower motor), modern refrigerant (R-410A or A2L, not R-22), and you're staying in the home only 1-3 more years. Replace makes sense when: system over 14 years old with any major repair on the table, compressor failure on an AC over 8 years old, cracked heat exchanger on a furnace, R-22 refrigerant system needing top-off, repeated repairs in successive years, or the rebate stack is on (currently 20-30% off replacement). Three failure modes always tip toward replace: cracked heat exchanger (CO risk + uneconomic to repair), AC compressor failure (60-75% of new outdoor unit cost), and R-22 refrigerant systems leaking (R-22 phased out 2020). We present both paths with numbers on every diagnostic visit and let you choose. --- ## Compare Tier — Article: Geothermal vs heat pump vs furnace: 15-year cost of ownership **URL:** https://olearyplumbingandheating.com/learning-center/compare/geothermal-vs-heat-pump-vs-furnace-cost-of-ownership Three systems modeled out for a 2,400-3,400 sq ft Wisconsin home: geothermal heat pump + forced air (highest up-front, lowest operating cost, 25+ year loop life); cold-climate air-source heat pump (mid-range up-front, mid-range operating cost, ~15-year life); 95-98% AFUE furnace + 16-SEER2 AC (lowest up-front, mid-range operating cost, ~12-15 year life). Installed costs before incentives: geothermal $40-65k (varies wildly with site engineering); CCHP $11-18k; dual-fuel hybrid $13-23k; furnace + AC $9-15k. Incentive stack: geothermal stacks 30% federal 25D credit + Focus on Energy custom rebate + utility rebate (covers 35-45% of net); heat pump stacks federal 25C up to $2,000 + Focus on Energy tiered + utility + manufacturer; furnace + AC stacks federal 25C up to $600 each. Annual operating cost: geothermal $900-$1,300; CCHP $1,300-$1,900; propane furnace + AC $2,200-$3,200; natural gas furnace + AC $1,400-$2,100. 15-year total cost of ownership tightens to within a few thousand dollars across all four. Geothermal pulls ahead at 20+ years. --- ## Compare Tier — Article: Reverse osmosis vs water softener: which water-quality system do you need? **URL:** https://olearyplumbingandheating.com/learning-center/compare/reverse-osmosis-vs-water-softener Two different jobs. A water softener treats the whole-house supply, removing calcium and magnesium via ion exchange. An RO system treats drinking water at a single tap (usually the kitchen sink), using a semi-permeable membrane to remove 95-99% of dissolved solids. Softener removes hardness, not chemicals/dissolved solids; RO removes dissolved solids (sodium, chloride, fluoride, lead, arsenic, nitrate, chromium), some membranes certified for PFAS. Softener installed $1,500-$3,500; RO installed $400-$1,200. Softener operating cost $90-$140/year in salt; RO $80-$200/year in filters. Common Wisconsin well-home configurations: softener alone for most Walworth County homes; RO at kitchen sink for drinking; full stack (iron filter → softener → RO) for hard well water with iron; RO is the right tool for specific contaminants like PFAS, arsenic, nitrate at the drinking-water tap. RO membranes foul early without a softener upstream on hard water. --- ## Compare Tier — Article: Tankless vs tank water heater: side-by-side for the lake-country home **URL:** https://olearyplumbingandheating.com/learning-center/compare/tankless-vs-tank-water-heater-side-by-side Decision matrix table covering 12 factors: upfront cost ($2.5-4.5k tank vs $4.5-8k tankless); lifespan (10-12 yr tank vs 20+ yr tankless); operating cost (tankless wins small household, even on large household); peak demand (tank wins, 3+ simultaneous hot taps); endless hot water (tankless wins single demand); space saved (tankless wall-mount); cold-climate supply water (tank no penalty, tankless rated flow drops 30%); vacation home / long vacancies (tankless wins); hard-water maintenance burden (tankless annual descale is more critical); gas line upsizing (often required for tankless); recovery time. The tie-breaker question: peak demand in gallons per minute. Under 4 GPM peak = tankless likely fine; over 6 GPM = well-sized tank wins; in between depends on supply temp + gas service. Lake-country specific: long-vacancy properties strongly favor tankless; well water with iron + hardness is brutal on tankless heat exchangers; tankless winterization is easier than tank. --- ## Compare Tier — Article: Whole-house generator vs portable: when each makes sense **URL:** https://olearyplumbingandheating.com/learning-center/compare/whole-house-generator-vs-portable Whole-house standby generator: permanently mounted outside, natural gas or propane fueled, automatic transfer switch (ATS), self-tests weekly. Portable generator: wheeled gasoline-fueled unit, manual operation, refueling required every 6-10 hours. Standby installed $9-18k for 14-24 kW residential; portable $700-2,500 plus inlet/interlock install. Standby capacity 10-30 kW (powers entire house + well pump + AC); portable 4-9 kW (furnace + sump + fridge, not AC). Standby maintenance $300-450/year on service plan; portable carburetor goes bad with stale fuel. Standby wins when: you have a well pump (no grid means no water), you're often away, multi-day winter outages are the threat, medical equipment or work-from-home, you can do natural gas (infinite fuel). Portable wins when: outages infrequent and short, budget constrained, home most of the time. Portable safety reality: kills people in Wisconsin every year from CO poisoning — never run in an enclosed space, even with door open. We install primarily Generac and Kohler standbys. --- ## Compare Tier — Article: Choosing a local plumber vs the metro chains **URL:** https://olearyplumbingandheating.com/learning-center/compare/choosing-a-local-plumber-vs-metro-chains Two different business models. Local trades contractor: employs the technicians who show up, runs a small fleet, lives in the community, answers to its reputation; customer base is repeat for decades. Metro chain: typically private-equity-owned aggregator, high-volume + high-marketing, technicians often commissioned on add-on sales. Both can produce good work; the experience differs. What to actually compare: licensing + insurance (verify both the company's contractor license AND the on-site technician's personal license); response time (local 1-4 hour emergency; chain 2-8 hour or next-day); pricing transparency (flat-rate books vary, chains have commissioned sales presentations); who actually shows up (employee tenure matters — O'Leary's HVAC techs average 8+ years, master plumbers 12+ years); will they pull the permit; warranty service in 4 years; references from your specific neighborhood. How to decide: get 2+ quotes for any project over $5k, confirm both pull permits, compare equipment specs apples-to-apples (model numbers + AHRI references), ask each for a past customer in your area. --- ## Compare Tier — Article: York vs Lennox vs Bradford White — a contractor's honest comparison **URL:** https://olearyplumbingandheating.com/learning-center/compare/york-vs-lennox-vs-bradford-white-contractor-comparison We install all three. York (Johnson Controls family): strong cold-climate heat pump lineup (Affinity / YHM down to deep negative temps), solid build quality especially on gas furnaces, reliable parts pipeline through Johnson Controls distribution, 10-year parts warranty standard. Lennox: industry-leading variable-speed inverter compressors (SLP98V, XC25, SL28XCV), iComfort thermostat ecosystem, best-in-class SEER2/AFUE numbers — but sustained parts-pipeline challenges (specialty boards and variable-speed motors at 4-12 week lead times over the last two years), premium pricing. We honestly disclose this when quoting. Bradford White (water heaters): contractor-only distribution (not at big-box stores), Hydrojet cold-water inlet reduces sediment turbulence, Vitraglas tank lining, reliable parts pipeline through local supply houses — our standard tank water heater. For tankless we install Navien, Rinnai, and Bradford White. The point: a great installer with a mid-tier brand outperforms a mediocre installer with a premium brand. Sizing, refrigerant charge, ductwork sealing, combustion analysis, water conditioning, and annual maintenance determine equipment life more than brand. --- ## Compare Tier — Article: Iron filter vs UV vs softener — well-water treatment in Walworth County **URL:** https://olearyplumbingandheating.com/learning-center/compare/iron-filter-vs-uv-vs-softener-well-water-treatment Three different problems. Iron filter removes dissolved iron and manganese. UV sterilizer kills bacteria and viruses. Water softener removes calcium and magnesium hardness. Diagnostic flow: test 1 hardness (over 7 gpg = softener); test 2 iron (over 0.3 ppm = iron filter); test 3 manganese (over 0.05 ppm = greensand media); test 4 bacteriological (coliform present = UV + shock chlorinate well; e. coli = immediate well disinfection); test 5 pH (under 6.5 = acid neutralizer). The correct install sequence in nearly every Walworth County well home: well pump → acid neutralizer (if low pH) → iron filter (if iron) → UV sterilizer (if microbiological) → softener → RO at kitchen sink. Putting a softener before an iron filter is the most common DIY mistake we re-engineer. Three iron-filter types: air-injection oxidation (1-10 ppm iron), greensand/catalytic media (iron + manganese), chlorination + carbon (very high iron or iron bacteria). UV requires pre-filtration, annual lamp replacement, and continuous power. Full stack installed: iron + UV + softener + RO = $5,000-$10,000. --- ## Act Tier — Article: Emergency plumbing checklist: when to call O'Leary **URL:** https://olearyplumbingandheating.com/learning-center/act/emergency-plumbing-checklist-when-to-call-oleary Step-by-step for the most common emergencies. Burst pipe: shut off main water valve, open a low-elevation faucet to drain, move belongings, photo for insurance, call (262) 642-7747. No heat in winter: check thermostat, breaker, gas valve (smell gas = evacuate + call WE Energies + 911 first), check filter (clogged trips high-limit), then call us. No hot water: check breaker / pilot, look for tank leak (shut off water inlet + gas/electric if leaking), call us. Sewer backup: stop using all water immediately, avoid contact (real biohazard), open basement floor cleanout slowly with bucket ready, call us. Frozen pipes: shut off main as freeze-burst precaution, open affected faucet, apply gentle heat (hairdryer, warm towels, never open flame), call us if you can't safely thaw. Smell of gas: everyone out of house, no switches, no phone inside, call gas supplier + 911 from outside. We answer 24/7. Average emergency response 60-90 minutes from dispatch. --- ## Act Tier — Article: Should I get a second opinion on my HVAC quote? **URL:** https://olearyplumbingandheating.com/learning-center/act/should-i-get-a-second-opinion-on-my-hvac-quote Yes if any apply: quote over $5,000, contractor pressuring you to decide today, "unsafe" or "red-tagged" claim without specifics, unfamiliar brand/model, no permit + inspection line items, full payment up front, or just don't feel right. The Free Second Opinion is a scheduled in-home visit where we look at the existing system, run our own diagnostic (refrigerant pressures, electrical, ductwork, Manual J load calc), read the competing quote carefully, tell you plainly whether the diagnosis is right + the equipment is right-sized + the price is reasonable, and quote the same scope ourselves for side-by-side comparison. No obligation. What we check: is the diagnosis right ($40 capacitor vs "compressor is failing"); is the equipment correctly sized; are the model numbers premium or value tier (AHRI reference number); is the price reasonable; is the rebate stack included; is the permit included. What it isn't: a sales call. If the original quote is fair, we say so. Typical visit 45-75 minutes, scheduled within 3-7 business days. --- ## Act Tier — Article: Annual maintenance plans explained — what's included + how to enroll **URL:** https://olearyplumbingandheating.com/learning-center/act/annual-maintenance-plans-explained The O'Leary plan covers all three major home systems: HVAC, plumbing, AND water quality — most maintenance plans in the industry cover only HVAC. Fall HVAC visit: combustion analysis on gas equipment, heat exchanger inspection (CO safety), gas pressure check, burner cleaning, blower amp draw, filter change, thermostat calibration, condensate drain flush, safety control verification. Spring HVAC visit: refrigerant pressure check, condenser coil clean, capacitor + contactor inspection, drain flush, reversing-valve cycle test for heat pumps. Plumbing inspection: whole-house leak check, water heater flush, anode rod check, T&P relief valve test, supply valve operation, sump pump test. Water quality inspection: softener resin + regeneration cycle, salt level + salt bridge check, iron filter media + backwash, UV lamp intensity, RO pre-filter + membrane, free hardness + iron test. Benefits: priority emergency response, 10-15% discount on parts + labor, no diagnostic fee on plan visits, documented service history maintaining manufacturer warranties, catches problems early. --- ## Act Tier — Article: How O'Leary handles permits + inspections so you don't have to **URL:** https://olearyplumbingandheating.com/learning-center/act/how-oleary-handles-permits-and-inspections On every job requiring a permit we are the licensed contractor of record. We pull the permit, pay the fee at cost (passed through on your invoice), coordinate inspection scheduling with the AHJ, meet the inspector on site, address any inspector items same-day where possible, and hand you the signed-off closeout paperwork. You do nothing. Step-by-step: 1) determine the AHJ for your specific address (Walworth, a Walworth municipality, Waukesha, a Waukesha municipality, Racine, or a Racine municipality — each is different); 2) file the permit application with our Wisconsin contractor license number; 3) pay the fee at cost ($50-250 typical, AHJ-dependent); 4) do the work per the approved scope; 5) schedule the inspection (1-7 business days typical); 6) meet the inspector on site — you don't have to be home; 7) receive the closeout, save the paperwork (your insurer and any future buyer will want it). --- ## Act Tier — Article: Financing a new system through Synchrony: terms + how it works **URL:** https://olearyplumbingandheating.com/learning-center/act/financing-a-new-system-through-synchrony Synchrony Bank is our financing partner. Term options: 12, 24, 36, 60, and 84 months. Same-day approval on most applications, approval up to $20-50k typical (covers nearly every residential job). Promotional offers rotate: no-interest if paid in full within 12/18/24 months (deferred interest from purchase date if not paid in full by promo end — read the disclosure); reduced-rate fixed APR over 60/72/84 months; manufacturer-specific promos. How it works: apply online or in person; approval in minutes; sign project contract referencing approved account; project completes; final invoice charged to Synchrony; first statement ~30 days later. Pre-pay always allowed, no penalty on our promos. Promo deferred interest has a clock — pay it off before the promo end or interest accrues from purchase date. Hard credit inquiry on the application. Worked example: $14,000 cold-climate heat pump project, less $500 Focus on Energy rebate, less $300 utility rebate, less $2,000 federal 25C (claimed at tax time) = $11,200 net financed at 84-month promo rate ≈ $145-185/month. --- ## Act Tier — Article: Free in-home estimates — what to expect from your O'Leary visit **URL:** https://olearyplumbingandheating.com/learning-center/act/free-in-home-estimates-what-to-expect We never quote a major system sight-unseen. The 60-minute walkthrough covers: load calculation (square footage by floor, window count, insulation, ductwork, infiltration cues — Manual J load calc not square-foot rule of thumb); current system inspection (existing equipment model + age + condition, refrigerant type — R-22 matters, duct sealing, thermostat capability, electrical service capacity, gas line size); water-quality assessment if relevant (free hardness/iron/TDS test on the spot); conversation about your priorities (length of stay, problems to solve, budget envelope, comfort issues). What we leave behind: written quote with itemized scope, equipment model numbers + AHRI references, accessories, permits, rebate stack modeled; side-by-side options where valuable; time to decide (quotes valid 30 days, no pressure to sign in our presence). What we won't do: quote sight-unseen, pressure-sign, sell you a system you don't need (if your furnace is 6 years old and needs a $250 ignitor we'll tell you), or hide the rebate math. --- ## Permits Pillar — Article: Permits & code compliance for plumbing, heating, cooling, and electrical work in Walworth, Waukesha, and Racine Counties **URL:** https://olearyplumbingandheating.com/learning-center/permits/permits-and-code-compliance-for-plumbing-heating-cooling-and-electrical-in-southeast-wisconsin A trade permit is a formal authorization from the local AHJ (Authority Having Jurisdiction) allowing a licensed contractor to perform a specific scope of work, triggering a follow-up inspection to verify code compliance. Not optional even for small projects. Plumbing permits typically required for: water heater replacement, repiping, new fixtures, sewer lateral replacement, backflow preventer, most water-quality work touching building drinking-water supply. HVAC permits required for: furnace replacement, AC/heat-pump replacement, new ductwork, geothermal loop, gas-line work. Electrical permits required for: service panel upgrade, any new branch circuit, hot tub/pool/dock/pier wiring (NEC 555/680), whole-house generator + transfer switch, significant rewiring. Three-county AHJ landscape: Walworth County Land Use & Resource Mgmt (Elkhorn) plus municipalities (Town of Linn, City of Lake Geneva, Williams Bay, East Troy); Waukesha County Parks & Land Use plus municipalities; Racine County Planning & Development plus municipalities. All adopted Wisconsin Uniform Dwelling Code layered with trade codes. Failure modes when unpermitted: insurance claim denial, real-estate closing blocked, AHJ-ordered removal, manufacturer warranty void, and safety (CO incidents, house fires, electric shock drowning). --- ## Permits Spoke — Article: Do you need a permit to replace a water heater in Wisconsin? **URL:** https://olearyplumbingandheating.com/learning-center/permits/do-you-need-a-permit-to-replace-a-water-heater-in-wisconsin Yes, almost always. Gas tank → gas tank: plumbing permit (sometimes mechanical). Electric tank: plumbing + electrical permit. Tankless conversion: plumbing + mechanical (venting + gas line) + sometimes electrical — the most permit-heavy scenario. Tankless → tankless: plumbing, possibly mechanical. Why: water heater touches three life-safety systems — combustion/venting (wrong venting = CO into home), gas pressure/leak testing (25 psi for 15 min no-drop test typical), T&P relief discharge (full pipe diameter, proper termination). Beyond safety, the paper trail preserves manufacturer warranty, satisfies insurance, and prevents closing blowups. Typical permit fee $50-120 depending on AHJ for residential gas tank-to-tank. Tankless conversion permits stack: plumbing + mechanical + possibly gas-line upsizing + possibly electrical. --- ## Permits Spoke — Article: Electrical service panel upgrade permits & inspections **URL:** https://olearyplumbingandheating.com/learning-center/permits/electrical-service-panel-upgrade-permits-and-inspections The most permit-heavy electrical job a homeowner schedules. Common reasons: 60/100A service too small for modern load (HVAC + EV + heat pump); known unsafe panels (Federal Pacific Stab-Lok, Zinsco); aluminum-bus panels; lightning damage; required by project (geothermal, generator, EV charger). No DIY path — licensed contractor required (utility won't re-energize otherwise) + electrical permit required + utility coordination required. Failure modes: utility not coordinated (job stalls); grounding system not brought up to current code; bonding bus errors (neutral and ground separation in subpanels); arc-fault/GFCI requirements per current NEC. Project timeline: walkthrough + quote → permit filed → install day (utility disconnects in morning, new panel + meter + grounding installed, all branch circuits transferred, inspection scheduled) → inspection (1-3 business days) → utility re-energizes upon pass → closeout. Typical residential 200A panel upgrade $2,800-$6,500. Permit fees $90-250. --- ## Permits Spoke — Article: What happens if work isn't permitted or up to code in Wisconsin? **URL:** https://olearyplumbingandheating.com/learning-center/permits/what-happens-if-work-isnt-permitted-or-up-to-code-in-wisconsin Five real consequences, none theoretical. 1) Insurance claim denial. Homeowners contracts have explicit clauses requiring code-compliant maintenance/permitted improvements. We've been on jobs where claims got reduced or denied after a loss traced to unpermitted prior work. 2) Closing delayed or killed. Buyer's inspectors note unpermitted furnaces, bathrooms, sub-panels, dock electrical; buyer's attorney requires retroactive permitting, replacement of non-compliant work, or significant price reduction — delays of 4-12 weeks, sometimes deals fall through. 3) AHJ-ordered removal. We've been called to undo unpermitted basement bathrooms installed by handymen. 4) Manufacturer warranty void. 10-year compressor warranty becomes 10-year compressor expense. 5) Safety — the only one that matters. Unpermitted electrical/gas/venting work kills people in Wisconsin every year. CO incidents. House fires. Electric shock drowning. The inspector's job is to prevent each. What to do if you already have unpermitted work: don't panic — retroactive permitting is a real path. Have a licensed contractor inspect, file the retroactive permit, get it on the record before you sell. --- ## Glossary — 34 industry terms **URL:** https://olearyplumbingandheating.com/learning-center/glossary Plain-English definitions of plumbing, HVAC, electrical, and water-quality terms used throughout the Learning Center.
