Common HVAC Problems
Your heating and cooling system works hard year-round. But when something goes wrong, it can disrupt your comfort and efficiency.
Here are some of the most common HVAC issues we handle:
HVAC SYSTEM NOT TURNING ON
If your HVAC system refuses to start, it could be caused by thermostat malfunctions, electrical issues, or a faulty control board. Our experts will diagnose the problem quickly and get your system back up and running.
LEAKING WATER OR REFRIGERANT
Puddles or refrigerant leaks around your indoor or outdoor unit are signs of trouble. Left unaddressed, these can cause serious system damage. We’ll locate the source of the leak, make repairs, and ensure your system runs efficiently again.
WEAK OR UNEVEN AIRFLOW
Hot and cold spots in your home often point to poor airflow. This can result from blocked ducts, dirty filters, or a failing blower motor. We’ll inspect your system and restore balanced, consistent comfort throughout your space.
BLOWING INCORRECT AIR TEMPERATURE
If your HVAC system is blowing cold air in heating mode or warm air in cooling mode, it could indicate thermostat calibration issues, refrigerant problems, or compressor failure. We’ll find the cause and restore the right temperature quickly.
SYSTEM FREEZING OR OVERHEATING
When your HVAC system freezes up or overheats, it may be due to airflow restrictions, dirty coils, or mechanical wear. Our technicians will resolve the root issue and help prevent future breakdowns.
