It’s the middle of winter and you notice your home is getting colder by the minute. There are a number of reasons a furnace isn’t producing heat. Should you be ready to bust out a few hundred dollars? Not just yet. It could be a cause for concern; however, more than likely, it could be a small problem that has an easy solution.
Reasons Your Furnace Isn’t Heating Your Home
Before you call in the experts, we recommend taking a look at some of the most common reasons your furnace isn’t heating your home. Many times, all it requires is a simple fix – one that could be as easy as flipping a switch, changing a setting, or replacing a filter. Take a look below and see you can find the solution on your own.
Your filter is too dirty. We can’t say it enough: change your filters! Replacing your filters keeps your furnace running efficiently. It also keeps your furnace running. A dirty filter restricts the airflow, which can cause the heat exchanger to overheat. This causes the system to shut down. That is why it is important to replace your filter regularly. We recommend every three months.
Your thermostat is on the wrong setting. The problem may not be your furnace at all. If your furnace isn’t heating, check your thermostat first. Is the thermostat on? Is it set to “heat” or did you have it on “cool?” Did the batteries die? Is there any dust or debris making it go on the fritz? Test your thermostat first.
Your furnace is off. Just like any other appliance, furnaces do have a standard switch. Perhaps it got flipped somehow. Or maybe you shut it off for a reason and forgot to turn it back on. While you’re at it, check your breakers, too.
The gas is turned off. If you have a gas furnace, check to see that someone didn’t turn off the gas valve.
Your ducts are leaking. If everything seems fine with the filters and thermostat, and your furnace seems to be working, check your ductwork. If there are gaps, cracks, or spaces in the ductwork, the warm air could be escaping before it reaches the rooms you want to heat.
Your vents aren’t open. If there’s a particular room that isn’t heating, check your vents. The reason could be as simple as a closed vent. Simply flip the lever and feel for air.
