What Are the Most Common HVAC Problems?

The HVAC system is an essential component of every household and business and is responsible for regulating temperatures and elevating comfort levels. However, like any other appliance, it can often break down and lead to various issues. Understanding the most common heating and air conditioning problems can help property owners identify the issue ahead of time and prevent costly repairs or damage to the system. Some of the most common HVAC problems include dirty filters, leaking refrigerant, faulty thermostats, clogged air ducts, and worn-out parts. These problems can lead to ineffective heating or cooling, reduced energy efficiency, and poor indoor air quality. Therefore, it’s best to keep an eye out for any signs that may indicate your furnace or air conditioner needs to be serviced.

Signs Your HVAC System Needs Repair:


  • If your energy bills have seen an unexpected increase
  • If your heater is blowing cool air and your air conditioner is producing warm air
  • If your system is making loud banging, clanking, or rattling noises when running
  • If your property’s humidity levels have changed
  • If your system is leaking water
  • If your property has accumulated more dust than usual
  • If your HVAC unit is continuously cycling
  • If your room temperature fluctuates throughout the property
  • If your overall airflow is weaker than normal
  • If your system is emitting musty, mildewy, or burning like odors  

If you suspect an issue with your system or notice any of the above signs, be sure to seek assistance from our qualified Waukesha HVAC repair technicians to ensure a proper diagnosis and repair is provided.

Should You Repair or Replace Your HVAC System?

When it comes to your HVAC system, there may come a time where you are faced with the decision to repair or replace. It can be a tough choice, especially if you're dealing with multiple issues. In general, if your unit is less than 10 years old and the repairs needed are minor, then going with a repair might be more cost-effective. However, if your heater or air conditioner is nearing the end of its lifespan, has major issues, has decreased in efficiency, or is needing similar or constant repairs, then a replacement may be in order. Ultimately, it's important to weigh the upfront cost of a new system against the potential savings in energy efficiency and repair costs. We recommend consulting with a trained Waukesha heating and air conditioning technician from our team who can inspect your unit and help you make an informed decision about whether repair or replacement is truly the best option.
