Why Isn’t My Furnace Keeping Me Warm?


Arizona winters might not get cold enough that you need to cozy up with your partner in front of a fireplace. However, there still are nights where the temperature does drop, and you want to make sure your furnace is working when it gets cold.

The worst thing that can happen is when you are enjoying the relatively mild winters and suddenly you realize that your home is uncomfortably cold. You turn on your furnace, and all it does is blow cool air in your face. We will discuss some of the reasons why your furnace isn’t heating so you can understand when to call us for furnace repair in Glendale, AZ.

Why Isn’t it Heating?

There could be several reasons why your furnace is not heating, and some of the most common of them are listed below.

Faulty Thermostat

The problem might not be with your furnace at all. Sometimes, it is nothing but a faulty thermostat. If your furnace is not blowing warm air, try resetting the thermostat. It could be misreading the indoor temperature and not regulating the furnace properly.

Clogged Air Filter

Another common reason your furnace is not heating is that you have not cleaned the air filter in a while. As the unit operates, it accumulates dirt and dust that can block the airflow. If you have not changed your air filter recently, that could be causing the problem. Changing your air filter every three months can help you keep your furnace running smoothly.

Leaking Ducts

If your furnace is working properly, but all the heat is still not circulating inside the house, there could be a leak in the ductwork. A breach in the ducts can cause the warm air from your furnace to leak out of the ventilation system and not allow it to circulate around the house as it should. It can even cause a significant drop in temperature from getting worse by letting cool air in, depending on where the breach is.

Heating Element / Gas Burner Problems

Another very common reason your furnace isn’t heating is that there is a problem right at the heart of your appliance. If you are using an electric furnace, there could be a problem with the heating element. Gas furnaces can also face problems with the gas burners responsible for heating the air before distribution.

Call a Professional

While you can try to find out what is wrong with your furnace, we would recommend seeking the help of a qualified professional. You might make the wrong decision on how to deal with the problem if you are not an expert in HVAC systems. A certified professional can quickly determine the source of the problem and fix it for you.
