Did you know that there are an average of 10.6 appliances in a single household? 

Winter is hard enough without being plagued by a malfunctioning heating unit. However, it is essential to know what to do when you discover that all the cold air is due to a simple fix and it’s not a significant issue with the unit.

Here, we’ve compiled some of the most common reasons why is my heater blowing cold air. Read on!

Thermostat Problems

If your heater is blowing cold air, it could be due to a problem with your thermostat. They are responsible for regulating the temperature in your home, so if it isn’t working properly, your heater won’t work correctly either.

If you think you have a malfunctioning heater, it’s best to have heater repair services to take a look at it.

Issues With the Heating System

Several things could be causing your heater to malfunction. This could be due to a tripped circuit breaker or a fuse. It could be an issue with the heating system itself.

If the system is not receiving enough power, it will not be able to generate enough heat to warm the home. If you’re unsure what the problem is, it’s best for a heating technician to take a look to know why is my heater blowing cold air.

Ductwork Problems

There are a few reasons your heater may be blowing cold air, but one of the most common is ductwork problems. 

Ductwork is the system of vents and pipes that carry hot air from your heater to the different rooms in your home. If there’s a leak or blockage in your ductwork, the air can escape before reaching your living space.

If your home’s ductwork is not properly sealed or insulated, heat can escape through the cracks and holes, leaving you with cold air. 

Poor Insulation

When the outside temperature drops, you turn on your heater to stay warm. Poor insulation is one possible reason.

If your home isn’t well insulated, heat can escape through the walls and ceiling, making your heater work harder to maintain a comfortable temperature.

Inadequate insulation is also a leading cause of frozen pipes. By improving the insulation in your home, you can save money on your energy bills and keep your family warm all winter long.

Windows and Doors Are Not Correctly Sealed

One possibility is that your window and doors are not correctly sealed, allowing cold air to enter your home. Maybe your heater is not sized perfectly for your home, meaning it can’t generate enough heat to offset the cold.

Your heater may simply be old and in need of repair or replacement. If you’re unsure what the problem is, it’s best to consult a professional to diagnose and fix it.

Knowing Why Is My Heater Blowing Cold Air

If your heater is blowing cold air, it could be because the thermostat is set too low, the pilot light is out, or the furnace is not getting power.

You can try turning up the thermostat, relighting the pilot light, or checking the fuse box. If none of these solutions work, you may need to call a heating repair technician and ask “why is my heater blowing cold air?”
