Troubleshooting Basic HVAC Problems

Before contacting an expert, there are some simple troubleshooting steps you can take.

  1. Inspect the Thermostat: Sometimes, a basic calibration on your thermostat can resolve the issue.
  2. Change the Filters: Dirty filters reduce airflow and weaken efficiency. Periodically change them to maintain best efficiency.
  3. Remove Debris from Outdoor Units: If you have a external AC unit, make sure it’s free of leaves, dirt, and debris.
  4. Check the Circuit Breaker: Your system may not be powered on because of a faulty breaker.
  5. Fix Leaks: Duct leaks decrease efficiency and stress the system. Look for cracks around windows and doors.

Times to Call a Technician

While many simple repairs can be done by residents themselves, certain HVAC problems demand professional intervention. Below are some situations when calling an HVAC professional is a must:

  • Freon Leaks: Fixing refrigerants requires expert skills.
  • Voltage Issues: Damaged wiring or circuits present a safety hazard, so it’s best to leave it to a pro.
  • Icy Coils: This can indicate a major problem with airflow, refrigerant levels, or the thermostat.
  • Full System Breakdown: When the system is non-functional, detailed service or even replacement might be necessary.
