Bad Filters
Filters should be replaced regularly, usually every couple of months. When they’re forgotten about they get clogged up, which affects how air is circulated in the home.
A Bad Thermostat
Sometimes, the problem may not be the furnace at all but the thermostat causing the issues. When a thermostat isn’t working, it won’t communicate with the furnace properly causing the homeowner to think their heater is broken.
Missed Maintenance
Furnaces should have annual maintenance and cleaning to ensure that everything is in proper working order and there are no problems. With routine maintenance, furnaces are less likely to break down.
Improper Heater
In some cases, especially after a homeowner adds on to the home, the furnace may not work properly because it’s not the correct size for the home. That can cause the heater to continuously cycle or not heat the home at all.
Needs Replacing
Even a heater that’s been perfectly maintained eventually needs replaced. If everything has been checked over and there are still no signs as to why the heater isn’t working properly, it may be time to purchase a new one.
If you’re careful and take good care of your heater, it may last you many years. To learn more about common furnace problems to watch for, call E.T. Ferrell & Son Heating & Air Conditioning at 919-658-2971.
