The primary job of a furnace is to keep your home warm and comfortable. If it fails to do this, you have a problem on your hands. Nobody wants to be stuck with a furnace that isn't heating up but this is a problem many people will have to deal with at least once in their lives.

The issue of furnaces not adequately heating up the house may have a simple or difficult solution depending on the specific issue causing it. What can you do to remedy this problem?

Check if the Furnace is On

As simple as it sounds, the reason why your furnace isn't heating up your house could be that it's not even turning on in the first place. There are various reasons why the furnace may not be turning on, including lack of electrical power, a blown out pilot light, or no gas coming in. If you find the furnace isn't turning on, you should try to eliminate the simpler possibilities such as the power or gas being off.

Check Your Thermostat

Another common reason why a furnace may not be heating up is the thermostat. The settings of the thermostat are what tell the furnace when to turn on and off. If these settings are wrong, the thermostat won't turn on at all or won't heat your home to the right temperature.

Another reason to check your thermostat is that it might be malfunctioning. This means that despite what the settings are, it could be sending the wrong signals to the furnace.

Is Something Obstructing the Registers?

You may be blaming your furnace for a problem that has little to do with it. The registers are what deliver the heated air into rooms throughout the house, and these registers can become obstructed. If the HVAC system hasn't been used for a while, there may be a buildup of dirt and dust interfering with airflow from the registers.

Clean the Air Filters

Dirty air filters are another common issue with furnaces. The air sucked in by the furnace from the outside may contain a lot of dust and other particles. Over time, these particles can clog the filters and greatly reduce the airflow. This can also overwork the furnace.

When all else fails, it's a good idea to reach out to a furnace repair service such as Polar Aire Heating & Cooling Inc. Some furnace issues will call for skills and experience that you don't have.
