A furnace is meant to keep your house comfortable. If you notice that your furnace is not blowing air, there must be something wrong with it and you might need the help of furnace repair services. We are going to discuss some potential reasons and how you can solve them. Let’s begin!

The Temperature Is Incorrectly Set

When it comes to your furnace not blowing air, it could be due to the temperature being set incorrectly. In a multi-purpose household, this is often the case as family members tend to disagree on desirable indoor temperatures. For instance, one person’s “warm” could be “chilly” for another.

As a result, someone might have adjusted the temperature according to their own preference, which leads to the furnace not blowing air. If you are living with several family members, it is suggested that you discuss a mutually agreed temperature. A gas furnace will only blow air if the temperature is right. Otherwise, you might end up with cold air or nothing for that matter.

The Furnace Is Not In “Heat Mode”

One of the most common mistakes made by homeowners is that they tend to turn on the furnace in air conditioning mode instead of heat mode. The majority of the problems related to the furnace not blowing air is due to wrong settings.

This is actually a direct result of the confusion created by complex thermostats that offer a wide variety of features but are complicated for some. Therefore, if your furnace is not blowing air, make sure that it is adjusted to the right settings.

Bad Thermostat Installation

While temperature settings are one thing, installation is another. It is often the case that thermostat installations are done wrong. Plus, most homeowners fail to believe that there is a relationship between bad installation and the furnace not blowing air.

Even if the expert follows all the directions, but certain adjustments will not allow the furnace to work normally. In addition to that, it also might be that the thermostat chosen for installation is not compatible. This case is quite possible, given the fancy-self-install thermostat kits available in the market.

The Air Filters Are Clogged

Furnaces like other household appliances require maintenance. Furthermore, they include air filters that prevent toxic air from entering the house. Over time, these filters can be clogged due to dust and debris accumulation. Once the air filters are clogged, the furnace finds it difficult to inhale and exhale air.

As a result, in an extreme case, the furnace simply shuts down due to excessive stress. In case of clogged air filters, the furnace has to work harder and this heats up the components. Therefore, the unit shuts down as a safety feature.

If you notice that your furnace is not blowing air and is becoming excessively hot, you need to shut it down and clean the air filters. You can either clean and install them or simply replace them.

The Battery Is Dead

Thermostats rely on batteries to run. Oftentimes, the date and time displayed on the thermostat come out incorrect as the batteries need to be replaced. Without the batteries, the thermostat has to rely on the power supply of your house.

As a result, homeowners often go unnoticed that their thermostat is dumping its settings due to low or  worn-out batteries. This constant resetting of the settings might now allow the furnace to blow air. This could also cause your heating bills to increase as you crank the thermostat to compensate for the loss of warmth.

The Circuit Breaker Is Off

Finally, if the furnace fails to blow any air, it might be that there is something wrong with the circuit breaker. If there is a blown fuse, the circuit breaker will shut down the unit. This might raise your alarm but there is nothing to panic about as it is simply a safety feature doing its job.

If that is the case, you should consult a professional to solve the issue, and if the issue still remains unresolved, request a thorough checkup.

Final Word

Concluding, your furnace not blowing air might be due to any of the reasons above. Always hire professional furnace services Arlington VA for diagnosing and keeping up with the maintenance schedule. This will help prevent future related problems.
