Fix it Fast: Troubleshooting Common HVAC Problems

Troubleshooting Common HVAC Problems - Tips from Air Comfort

Dealing with HVAC issues can be frustrating, especially during the extremes of Minnesota's seasons. At Air Comfort, we want to empower homeowners by sharing simple troubleshooting tips for the most common HVAC problems.

Understanding these can save you time and possibly the cost of a service call:
​

1. System Won't Turn On:
   • Check your thermostat settings to ensure it’s set to heat or cool and that the temperature is correctly set.
   • Inspect the circuit breaker connected to the HVAC system. A tripped breaker is a common issue that can prevent the system from powering up.
2. Inadequate Heating or Cooling:
   • Replace or clean the air filter if it’s clogged, as this can restrict airflow and diminish system efficiency.
   • Ensure all vents are open and unblocked to allow proper air circulation throughout the home.
3. Unusual Noises:
   • Listen for specific types of noises: whistling might suggest an air leak, banging could indicate a loose part, and grinding may point to a motor problem.
   • Tighten any loose components and check for signs of wear on belts and bearings.
4. Thermostat Issues:
   • Verify that the thermostat is on and set to the correct mode. Replace the batteries if it’s battery-operated.
   • If problems persist, the thermostat may need recalibration or replacement.
5. Frequent Cycling:
   • Frequent on and off cycling can be caused by an oversized unit, a malfunctioning thermostat, or a clogged filter.
   • Check the filter first, then consider consulting a professional if the issue continues.
6. Water Leaks:
   • Check the condensate drain line for clogs, which can cause water to back up and leak.
   • Ensure that the drain pan is not cracked or overflowing.
