Despite regular maintenance, HVAC systems can encounter issues that affect performance and comfort. Here are common problems and troubleshooting tips:

1. Uneven Heating or Cooling

Check air filters for clogs and ensure vents are open and unobstructed. Clean ducts and inspect for leaks that could be affecting airflow.

2. High Energy Bills

Dirty filters, thermostat issues, or inefficient equipment can lead to increased energy consumption. Replace filters regularly and consider upgrading to energy-efficient models. Book an appointment with us!

3. Strange Noises

Rattling, squealing, or banging noises may indicate loose components or worn-out parts. Schedule an inspection to diagnose and address the issue.

4. Frequent Cycling On and Off

This could be due to a dirty filter, thermostat problems, or improper equipment sizing. Clean or replace filters and have the thermostat calibrated or replaced if necessary.

5. Frozen Evaporator Coils

Restricted airflow or low refrigerant levels can cause evaporator coils to freeze. Turn off the system and contact a professional to inspect and repair the issue.

6. Water Leaks

Leaking around the indoor unit could indicate a clogged condensate drain or refrigerant leak. Clean the drain line and schedule professional repair for refrigerant leaks.

7. Thermostat Malfunctions

Incorrect temperature readings or failure to respond to settings may indicate thermostat issues. Replace batteries, clean components, or upgrade to a programmable thermostat.

8. System Failure

If your HVAC system fails to turn on, check circuit breakers and thermostat settings. If issues persist, contact a professional for diagnosis and repair.

When to Call a Professional

While some HVAC issues can be addressed with DIY maintenance, others require professional attention. Consider calling a professional HVAC technician if:

  • You’re unsure about diagnosing or repairing the issue.
  • There are unusual odors or sounds coming from the system.
  • The system fails to heat or cool your home adequately.
  • Your energy bills spike unexpectedly.
  • You haven’t had professional maintenance in over a year.

Prompt professional attention can prevent minor issues from escalating into major repairs, ensuring your HVAC system operates efficiently and reliably.
