It's important to schedule regular HVAC system maintenance to avoid major repair problems. Even with regular maintenance, however, there are still going to be times that you need to call an HVAC repair expert. 

Here are some signs that it's time to call in a professional HVAC repair expert:

  • Your HVAC system isn't heating or cooling properly. This may seem like a no brainer, but if your home isn't comfortable even with your HVAC system running, it's time to call for repair.
  • Strange noises are coming from your HVAC system. If you hear are hearing any banging noises or other unusual sounds, this could be a sign that something is wrong.
  • Your energy bills are higher than usual. If you notice a spike in your energy bills, it could be a sign that your heater or air conditioner is working harder than it needs to be. Sometimes a simple repair can get things back to running more efficiently.
  • Your are noticing strange odors from your HVAC unit. If you notice a musty or burning smell coming from your HVAC, it could indicate a problem with your ductwork, electrical system, or another component.
  • Your HVAC system is leaking water. If you notice water pooling around your HVAC system or dripping from the ceiling, it could indicate a problem with your system's condensate drain or refrigerant line.

If you notice any of these signs or have other concerns that something doesn't seem right with your unit, it's important to call for HVAC repair right away. Delaying repairs can lead to more serious problems and more expensive repairs in the future.
