If your home feels unnaturally cold, you may increase the temperature on your thermostat to solve the issue. But if changing your thermostat doesn't fix the problem, take a look at your furnace instead. Furnaces can produce very little heat if they clog up with debris or if they have problems with the blower. Here are two things you can try right now to warm up your home.
Clean Your Furnace's Blower Chamber
The first thing you want to do is examine your furnace's air filter to see if it's clogged with dust and dirt. A blocked air filter can keep clean air from entering the blower chamber inside your furnace. If heat builds up inside the blower chamber, it can damage the motor inside the chamber.
After you change the air filter, allow your furnace some time to warm up your house. If the rooms in your house still feel icy or cold, switch off your furnace and check the blower motor chamber. The chamber houses the furnace's electric motor equipment. If debris clogs up the motor, it can shut down. You can dust off the motor with a small cotton cloth. If possible, sweep or vacuum out the chamber to help improve airflow through it.
Once you clean the motor, return power to your furnace and wait for it to fire up. If your home continues to feel icy, contact a residential heating system contractor for further assistance.
Call a Heating Contractor
A heating contractor will not only check your air filter and blower for problems, but they'll also inspect other parts of the furnace for potential issues, including the heat exchanger. Heat exchangers can get hairline cracks in their housing that allow gas and air to mix. The mixture of gases will cause problems with the furnace's burners and combustion chamber. A cracked heat exchanger can also be dangerous if it allows carbon monoxide and other odors to enter your air ducts or house.
The heating elements or burners inside the furnace can also be damaged or clogged with soot and dust. If any of these parts break down, your furnace won't have enough power to heat your home properly.
If your furnace doesn't work after the repairs, a contractor may recommend that you replace it as soon as possible. You can replace your furnace with something similar, or you can choose a more efficient heating appliance. A contractor may suggest that you use an energy-efficient model as your replacement.
