Is Your Furnace Not Responding to Your Thermostat?

Is Your Furnace Not Responding to Your Thermostat?

Several things might cause your furnace to ignore your thermostat’s demands. Accu-Aire has addressed them below. If you think you need professional help, don’t be shy to contact an experienced technician to assist you.

Check Your Filter

A clogged furnace filter restricts airflow. As a result, the exchanger in your system will overheat and automatically shuts off for safety reasons. If you set your thermostat for heat and the air is not warm, your exchanger may have shut off. Regularly changing your filter will help keep the mechanical parts of your furnace free from dust and dirt. Also, it may prolong your comfort equipment’s lifespan. We highly recommend changing your filter once a month.

Thermostat Issues

A malfunctioning thermostat won’t let your furnace to respond correctly. Check if it is set to “heat.” Then make sure if it is securely attached to the wall and no wires are loose or frayed. If it’s a programmable thermostat, check if the time and date are correct. Batteries should also be ready if there’s a power failure so you won’t lose your settings. You can try to test it by setting the temperature five degrees higher than the room temperature. If you hear the fan respond, your thermostat is functioning well.

Electrical Components

Is your red emergency switched on? You need to be sure. It may have been accidentally switched off. Then check the circuit breaker at your electric breaker panel. Look if there’s a blown or tripped fuse. It’s also a good idea to scan the panel if there are any loose wires or evidence of other issues. If the problem is complicated than a tripped fuse, you should contact your local HVAC technician.

Drain Lines

If you have a high-efficiency furnace, check your drain lines and be sure they are free of any debris build-up. You can flush the hose out with a bleach solution if it looks dirty.

Exterior Vent

If your furnace vents outside of your house, inspect if it is free of leaves or other debris. Sometimes, rodents and birds use these vent openings to make a nest. This step is significant in the spring and summer months.
