24/7 Emergency Service
If your heater isn’t responding to your commands and the temperature outside is steadily dropping, you might be wondering what to do next. There can be many possible causes for your heater failing to respond to the thermostat, and the only way to know for sure what the issue is with your HVAC system is to call an expert from a furnace repair service.
4 Most Common Heater Repair Issues
If you notice one of these top heater repair issues below, it’s time to call in the experts for heating system repair:
- Issues Unrelated to The HVAC Unit Itself
There are times that heating system failure is due to a simple issue unrelated to the actual heating unit. If your heating unit is connected to the home’s power grid, the circuit breaker can trip. To see if this may be the cause of your heater failing to turn on, find your fuse box and see if the switch that corresponds to your HVAC system is in the OFF position. Check the fuse box for any signs of an electrical short, like a smoky smell or scorch marks along the sides of the control board. - Dirt in The Furnace System
Maintaining the HVAC system might seem like an unnecessary task, especially if you don’t use your furnace much. But failing to maintain the system can lead to dirt getting into the key components of the furnace, like the blower motor and the burners. Once these parts of the HVAC system become weighed down with dirt, the entire system has to work harder to push out warm air. Eventually, the overwork and strain on the unit can cause it to shut down and stop responding to the thermostat. At this point, furnace repair from a professional is the only way to get it working again. - Pilot Light Problems
If your heater is gas-powered, the furnace’s pilot light may be out. Many furnaces have a gas reset valve that you can use to try and test the pilot light. Shut the gas off and wait five minutes before turning it back on and trying to start the unit again. If the furnace still does not turn on, there’s a good chance the flame that powers the heater has gone out. - Blower Motor Issues
The blower motor is the part of the system that pushes the heated air out and into the ductwork so it can be distributed through the house. When the blower motor gets clogged or shuts down, the thermostat may still respond to your commands and you may hear the unit switch on, but the home won’t get any warmer. If you have a newer unit, it may have a light to indicate whether the blower motor is working properly. If this light is glowing red, there is an issue that you should call an HVAC professional to investigate.
