Is Your Heater Blowing Cool Air? Here’s What You Should Do

It’s true that Beaumont, TX and the surrounding areas can get stifling hot in the summer. This makes you think that you have nothing to worry about when winter comes.

But the reality is, the winters can be quite tough as well. Temperatures can drop below 44 degrees, meaning you’ll need a good heater to stay toasty during this season.

Perhaps yours has been doing a good job this winter so far. But all of a sudden, you feel like it’s not heating up your house as efficiently. 

If you find that your heater is blowing cool air, then there are some things you can try before calling an expert. Read on to find out what to do if you’re thinking, “oh no, my heater won’t work!” We’ll go over some reasons why your heater might be blowing out cold air.

Your Thermostat’s Not Set Correctly

This might sound like a silly suggestion, but you’d be surprised at just how many people don’t check their thermostats before calling a Beaumont HVAC professional to come perform heater repair. So the first thing you want to do is take a look at your thermostat.

Once the season changes from hot to cold, many homeowners forget to set their thermostat on “heat” instead of “cool.” So when you’re sitting there shivering and your HVAC system starts to blow cool air out, then think about whether or not you’ve actually switched the settings on your thermostat.

If you check it and you have indeed set your thermostat to “heat,” yet your heater is still blowing out cool air, then you’ll want to consider the other points in this article.

You Have Electric Panel Issues

Let’s assume that your HVAC system is in perfect working condition. Then it might be a problem with your electric panel that’s causing your heater to blow cool air.

For example, if the breaker’s being tripped, the furnace won’t be able to turn on. It may even cause the pilot light to be off.

As a result of either (or both) things, your heater won’t get the heat it needs. So you end up with a heater that just blows cold air out.

As you may have already guessed, this is an issue that you shouldn’t try and fix yourself. A professional HVAC company can take care of this problem for you, quickly and safely.

There’s an Issue With Your Gas Valve and Pilot Light

When you realize that your heater is blowing out cold air, you’ll want to check the pilot light. After all, if the pilot light isn’t lit, then the furnace can’t function correctly.

You’ll be able to see immediately if the pilot light is on or not. If it’s not lit, then you most likely have a problem with the gas valve.

A malfunctioning gas valve can be due to something as simple as years of it accumulating dirt and debris. If you haven’t cleaned your HVAC system for quite some time, then this is a likely possibility. So give it a good clean and see if the pilot light will turn on.

If it doesn’t, then call an HVAC specialist in Beaumont to help you out.

Your Furnace Is Overheated

If your heater does blow out hot air for a little bit and then switches to cold air, then it’s very likely that your furnace is overheated. This can actually be a good thing, as it means your furnace’s limit switch is in working order.

The limit switch is there to turn off the burners so that if the furnace is working dangerously hard, nothing dangerous can happen further. Instead, it basically shuts off the burners and blower so the furnace can cool down to more normal levels.

Obviously, your furnace shouldn’t be overheating, nor should it be doing this often. If you keep feeling cycles of hot and cold air, you’ll have to check out your furnace’s air filter. A dirty filter can cause airflow to be blocked, which will cause overheating.

If cleaning or replacing the air filter doesn’t fix the cold air blowing out, you’ll want to call an HVAC company.

There Are Problems With Your Ductwork

Most people think that once you turn on your heater, it just magically turns all the cold air in your house into warm air. But the truth is, it’s much more complicated than that.

First, your heater will collect all the air in your home. It’ll them simultaneously heat the air and then also force cold air outside. This happens through heat exchange, and it must be done quite a few times before it actually starts warming up your house.

If there are issues with your ductwork, such as bad insulation, this can make the heat exchange process inefficient and much slower. As a result, you feel cool air coming out of your heater.

If it takes more than a few minutes for your heater to warm up your home, then it might be a sign that you need your ductwork looked at and repaired by an HVAC professional.
