If your HVAC system isn’t keeping your home comfortable, there are a few basic issues that might be causing the problem. While HVAC repairs need professional attention, understanding what’s going on can help you communicate better with an AC repair technician and maybe avoid unnecessary stress.
Check Your Thermostat Settings
Sometimes the solution is as simple as adjusting your thermostat. Make sure it’s set to “cool” in the summer or “heat” in the winter, and double-check that the temperature setting isn’t too high or too low. Dead batteries or a tripped circuit breaker could also prevent the thermostat from working properly.
Look at Airflow Issues
If your system is running but your home still feels stuffy or unevenly cooled or heated, airflow may be the issue. Dirty filters are a common culprit. When filters clog up, air can’t move freely, making your system work harder than it should. Swap out filters regularly—every one to three months depending on usage.
You’ll also want to make sure vents aren’t blocked by furniture, rugs, or curtains. Blocked vents can restrict circulation and cause uneven temperatures throughout your home.
Pay Attention to Unusual Noises
Strange sounds like banging, rattling, or screeching are usually a sign that something isn’t right inside the system. Loose parts, debris in the fan, or motor problems could all be to blame. If you hear anything out of the ordinary, it’s best to get it checked before the issue worsens.
Watch for Leaks or Moisture
Moisture around your system can be a red flag. It could be a clogged condensate drain or even a refrigerant leak. Refrigerant issues not only reduce cooling power but can also pose a health risk. Water buildup can lead to mold or damage, so don’t ignore any signs of leaking.
System Won’t Turn On
If your system won’t start at all, check the basics first: the thermostat, power switch, and breaker. If all of those seem fine, the problem could lie deeper—such as a malfunctioning capacitor or faulty control board.
