What to Check First If Your Heater Isn’t Working
When it is close to freezing outside, the last thing anyone needs is to arrive home to a cold house with a broken heater. The easiest way to prevent a heater failure is to regularly maintain your system in the fall, before the weather gets cold. Despite your best efforts, if your furnace has left you chilly, there are a few tips you can check before giving a heater technician a call that might save you some aggravation and get your furnace running quicker, too.
Check the Power
Some furnaces have an on/off switch that is frustratingly easy to switch off. If you store holiday decorations in an attic near your furnace, it is possible you switched off your furnace by mistake. If you’ve had any other technicians near your furnace, such as a cable installer, holiday lights installer, or plumber, consider checking the on/off switch on the furnace in your attic. If that doesn’t solve the problem, check the power supply and see if any of your electrical breakers for your furnace have tripped. Occasionally resetting a tripped breaker can get your heater going again. However, if the power keeps tripping off on your furnace that likely means a safety feature has been activated and it is wise to call a licensed professional to see what the problem may be.
Check the Thermostat
It may sound like a no-brainer, but you do need to turn your thermostat to the “heat” or “automatic” setting before your heater will click on. If you have the heat set to come on to maintain the indoor environment at 72 degrees and the thermostat is set to “cool,” your furnace will not turn on. Occasionally, smart thermostats can get “stuck” and need to be restarted. The easiest fix is to remove them from the wall, and reattach them to complete a manual reset. It’s similar to turning your computer on/off and takes less than a minute to do. If your thermostat runs on batteries, try replacing them.
Check the Filters
When was the last time you changed the air filters in your home? I hope the answer isn’t years! Clogged filters can wear out the electrical components that keep the warm air blowing through your home’s air vents. Some homes have filters in their return air vents AND an extra filter within their furnace. If this is the case, make sure both have been changed. Disposable filters are designed to be replaced regularly (1-3 months). Do yourself a favor and change out the filter if it has been longer than 3 months.
