Common HVAC Problems and Troubleshooting Tips

No Cool Air or Warm Air

Possible Causes:

  • Dirty air filters
  • Incorrect thermostat settings
  • Refrigerant issues

Troubleshooting Steps:

  • Check and replace filters. Dirty air filters can restrict airflow and reduce cooling or heating efficiency. If they are dirty or clogged, check them and replace them.
  • Thermostat settings. Ensure your thermostat is set to the correct temperature and mode (cooling or heating). Sometimes, a simple adjustment can resolve the issue.
  • Call a professional. If the air is still not at the desired temperature, there might be a refrigerant leak or other problems. Contact IRBIS HVAC to diagnose and fix the issue.

HVAC Unit Not Turning On

Possible Causes:

  • Tripped circuit breaker
  • Blown fuse
  • Thermostat problems

Troubleshooting Steps:

  • Reset the circuit breaker. Locate your electrical panel and check if the HVAC system’s circuit breaker has tripped. If so, reset it by switching it off and then on again.
  • Check and replace fuses. Inspect the fuses in your HVAC unit and replace any blown ones with new ones of the same type and rating.
  • Ensure the thermostat is set correctly. Verify that the thermostat is turned on and set to the correct mode (cooling or heating) and appropriate temperature setting.

Unusual Noises

Possible Causes:

  • Loose parts
  • Debris in the unit
  • Motor issues

Troubleshooting Steps:

  • Inspect and tighten parts. Check the HVAC unit for any loose screws, bolts, or components. Tighten them as needed or call an HVAC professional.
  • Clean debris. Look for any debris or foreign objects that might be causing noise. Carefully remove any obstructions.
  • Call a professional for motor repairs. If the noise persists, it could be due to motor issues. Contact IRBIS HVAC for a thorough inspection and repair.

Weak Airflow

Possible Causes:

  • Clogged ducts
  • Dirty air filters
  • Blower issues

Troubleshooting Steps:

  • Clean or replace filters. Check and replace dirty or clogged air filters to ensure proper airflow.
  • Check ducts for blockages. Inspect the ductwork for any blockages or obstructions. Clean the ducts to improve airflow.
  • Inspect the blower. If the airflow is still weak, the blower might be malfunctioning. Contact IRBIS HVAC to inspect and repair the blower.

Frequent Cycling

Possible Causes:

  • Thermostat issues
  • Dirty filters
  • Electrical problems

Troubleshooting Steps:

  • Adjust the thermostat. Ensure the thermostat is placed correctly and not influenced by external temperature sources (like direct sunlight or drafts). Set it to an appropriate temperature.
  • Replace filters. Dirty filters can cause the HVAC system to cycle on and off frequently. Replace them to improve system performance.
  • Call a professional for electrical issues. If frequent cycling continues, there might be underlying electrical problems. Contact IRBIS HVAC to diagnose and resolve the issue.

When to Call a Professional

Signs That Indicate a Need for Professional Help

If your HVAC unit remains non-operational despite troubleshooting common issues, it might indicate a deeper, more complex problem.

Unusual Noises

Grinding, screeching, or banging noises from your HVAC unit can signify serious mechanical problems, such as a failing motor or broken components requiring professional attention.

Burnt Odor

A burnt smell emanating from your HVAC unit is a red flag for electrical issues, such as a burnt-out motor or faulty wiring, which can pose a fire hazard if not addressed promptly.

Repeated Circuit Breaker Trips

If the circuit breaker frequently trips when your HVAC unit is running, it suggests an electrical fault that needs a professional diagnosis to prevent potential damage to your system or home.
