Why Is My Heater Blowing Out Cold Air?

Furnace | Anytime HVAC

The cold weather has arrived, so it’s time to crank up your heating unit and enjoy the warm indoors of your home. However, nothing ruins your moment better than feeling cold air coming out of your heater. After months of being neglected, it’s easy to question whether the unit even works.

In many cases, you might be able to fix the situation before it gets out of hand. However, there are circumstances where you will need extra care and expertise.

Here are a few reasons that your heater may be blowing out cold air:

Just Turned On

If you feel cold air right after you turn on your heater, it’s possible that your heater needs time to heat up. Most heaters blow out cold air at first because they can only use the air around the heater and don’t have any warm air available.

Over time, the heater should be able to heat the air around it and begin producing warm air. Keep the heater on for a few minutes to see if it gets warmer. If your heater still doesn’t heat after five minutes, take a look at your furnace to see if there is another problem.

Poor Insulation

In the event the heater still takes a while to heat, check your insulation. If you have poorly-installed insulation in your home, this may be why cooler air is coming out.

Quality insulation makes it easier to keep warm air in your home and doesn’t burn out your furnace. By overworking your furnace, you run the risk of causing more costly problems. If your furnace is taken care of properly, it is less likely to have periods where cold air blows out.

Check Pilot Light

If your heater still fails to push out hot air, check your pilot light. As the year goes on, it’s possible that your pilot light may have been accidentally turned off. This light ignites the furnace to heat your home’s air, so if the light isn’t lit, the furnace isn’t heating.

If the pilot light won’t light on your end, check with your gas supply to make sure it did not get turned off as well. You can either test other gas-power devices or call to make sure that there isn’t a fuel outage in your area.

If you smell gas, but still don’t see a flame, you may have a dangerous gas leak. Immediately turn off the gas supply, leave your house and call emergency services.

When To Call the Professionals

Furnace Technician | Anytime HVACWhile several of these problems can be diagnosed and fixed on your own, there are other problems that need a professional technician in order to be solved. A technician will know the specific trouble spots that are causing your heater to malfunction. If you still have trouble getting the air to heat after various attempts to fix it, contact a technician.

Here are just a couple of issues that need professional care:

Electrical—It’s better to leave anything electrical to your heating technician as they have the expertise to properly deal with wiring. It’s possible that there may be a malfunction with the wires in your thermostat.

Cracked Heat Exchanger—Having a cracked heat exchanger can produce poisonous carbon monoxide gases, so it must be handled immediately to protect you and your family. The heat exchanger is located inside the furnace and is where the air for your home is heated from the burned gas. You will likely be able to see a crack or hole by looking inside the furnace.
