All year long, you rely on your HVAC system to keep your home comfortable.

Signs You Need HVAC Repair or Maintenance

One of the best things you can do to keep your air conditioner and heater working well is to learn the signs of an HVAC problem. Knowing the symptoms of a problem and calling in professional help right away can save you money on repairs and prevent a small problem from turning into a large one.

You should call our team of Chesterfield HVAC technicians if you notice:

  • Burning smells or scorch marks around your air ducts
  • Strange sounds coming from your ducts
  • The air coming from your ducts is room temperature or hot when it should be cool
  • A broken or malfunctioning thermostat
  • Your heater or air conditioner won’t turn on
  • Your system runs continuously
  • Your system can’t keep up with the temperature you set
  • There are hot and cold spots in your home
  • You notice an unexplained increase in your utility bills

Your average heater or air conditioner will last for around 10 years. If your system is reaching the end of its lifespan, make sure you are keeping up with your seasonal maintenance. Routine maintenance can help you extend the life of your existing system and avoid breakdowns. If you are unsure when you last had your system inspected, or if you want help establishing a maintenance routine, call our HVAC technicians in Chesterfield, St. Louis, Ballwin, and Wildwood. We are always happy to help.
