Common Heating Problems We Repair
Our NATE-certified technicians diagnose the cause of the problem before recommending a repair — so you understand what is happening with your heating system and what options are available.
Furnace Won't Turn On
A furnace that won't start can have problems with the thermostat, ignition system, electrical components, safety controls, blower, or gas supply. AirTek diagnoses the system to determine why your furnace isn't operating.
Furnace Blowing Cold Air
If your furnace runs but blows cold or lukewarm air, the cause could be an ignition failure, gas valve problem, heat exchanger issue, overheating safety shutoff, or airflow restriction. We identify the actual cause before recommending a repair.
Heat Pump Not Heating
If your heat pump runs but isn't producing enough heat, the cause could involve refrigerant, airflow, controls, the outdoor unit, defrost cycle, or another component. We diagnose heat pump heating problems and recommend the appropriate repair.
Heat Pump Stuck in Cooling Mode
A heat pump that won't switch properly between heating and cooling can have a problem with the thermostat, controls, reversing valve, wiring, or other components. Proper diagnosis is important before replacing parts.
Short Cycling
A heating system that turns on and off repeatedly without completing a full cycle can be caused by thermostat problems, airflow restrictions, overheating, system sizing issues, or a failing component. Short cycling should be diagnosed promptly.
No Heat at All
When your heating system produces no heat at all, the problem could be electrical, mechanical, or related to the fuel supply. AirTek can diagnose the system and determine what is preventing your home from heating.
Unusual Heating Noises
Banging, rattling, squealing, grinding, or booming sounds from your furnace or heat pump can indicate a mechanical, electrical, or airflow problem. Identifying the source early may help prevent a more expensive repair.
Thermostat Problems
A faulty thermostat can prevent a heating system from operating correctly, cause short cycling, or keep the equipment from turning on. AirTek can diagnose thermostat and control problems and recommend the right solution.
High Heating Bills
An unexpected increase in heating costs can sometimes indicate reduced system efficiency, airflow restrictions, dirty equipment, failing components, or other issues. AirTek can evaluate the equipment to help identify potential causes.
If your heating system isn't working, don't wait for a small problem to become a major repair.
