Why Your Heater Might Be Blowing Colder Air Than Usual

As winter approaches, your heater becomes an essential aspect of your home. However, when colder air comes out instead of warm air, it can be a frustrating experience. This article discusses some of the reasons why your heater might be blowing out cooler air than expected, and how to fix the problem.

Thermostat Setting

It may sound simple, but one possible reason why your heater is blowing out colder air than usual is because the thermostat is set too low. Check your thermostat to make sure that it's set to a temperature that's warm enough for your preferences. If that's not the issue, then move on to the next plausible cause.

Dirty Air Filter

A dirty air filter can also cause your heater to blow out cold air. The air filter in your heating system helps to trap various particles in the air, however over time, they can become clogged with debris and dirt. This blockage prevents proper air flow and can result in cooler air being blown out of your heater. Replacing a dirty air filter is an easy and affordable fix that you can do on your own.

Pilot Light or Ignition System Problems

If your thermostat settings and air filter are both okay, then your problem could be related to your pilot light or ignition system. These problems can lead to malfunctioning of your heating system, ultimately causing cold air to come out of your heater. To fix the problem, it's best to call for professional heating repair services.

Blocked Ductwork or Vents

Blocked ductwork or vents could also be a reason why your heater is blowing out colder air than usual. When your ductwork or vents get clogged, it can restrict the airflow through your heating system, which results in less heat blowing through your vents. You should check and clean the ducts and vents from time to time to avoid such situations.
