3 Possible Reasons Your Furnace Isn't Keeping Your House Warm

When the temperatures are bitterly cold in the winter, your furnace might have a hard time keeping your home warm. The problem might be that the temperatures are colder than usual, and your furnace can't keep up due to inadequate insulation in your home.

However, if your furnace isn't working properly, it won't be able to keep you warm, and you might need to have furnace repair work done to get you through the rest of the winter. Here are three furnace problems that keep your house from being as warm as you like.

1. The Thermostat Or Wiring Malfunctions

The thermostat has the important job of triggering your furnace to turn on and off. If the thermostat is faulty, or if wiring from the thermostat to the furnace is bad, your furnace might not work properly. If your furnace runs erratically, it might not run long enough to heat up your house properly.

A problem with a thermostat or wiring is easy for a furnace repair technician to fix. Wiring can be changed or the connections can be tightened. A thermostat can be cleaned or replaced entirely so your furnace gets the signals necessary to turn on and shut off properly.

2. The Filter Or Furnace Is Dirty

One reason that annual furnace maintenance is important is to keep a dirty furnace from breaking down during cold weather. If your furnace isn't keeping you warm, check the filter and change it if it has dust built up on it. A dirty blower fan or a dirty combustion area in the furnace can keep your furnace from making and circulating enough heat too.

If you haven't had maintenance done on your equipment in a long time that included thorough cleaning, the repair technician might need to clean the furnace to see if that helps the furnace work properly. Sometimes a dirty furnace can cause damage to the equipment, and in that case, the technician might have to replace parts or make other repairs in addition to making sure the equipment is clean.

3. The Blower Fan Isn't Working

The combustion area of your furnace might be making heat, but without an operational fan, the heat won't spread through your house. The fan might stop working if the blower comes loose or if the motor breaks down. A furnace repair technician can replace broken parts in the fan system, whether the problem is mechanical or electrical, so the fan resumes blowing warm air through your home.

If it seems like your furnace isn't keeping your home as warm as it usually does, call a furnace repair professional for help. Otherwise, your furnace might break down completely, and that could leave you and your family in the cold while you wait for emergency repairs to be done.
