Furnace Repair Arlington: My Heater Is Blowing Cold Air

Read on to learn money-saving tips for heating repair in Arlington

To some folks, the idea of a Texas winter doesn’t sound too scary.

And sure, Arlington and Fort Worth don’t see the same kind of snow as Boston and Bangor. But it drops below freezing in this part of the world, and it does snow from time to time.

That means furnace repair matters as much here as it does anywhere else. Texans have to pay as much attention to the needs of their HVAC equipment as everyone else.

So what do you do if your furnace isn’t blowing warm air through your home?

For starters, you consider calling us and getting on a maintenance schedule to prevent this kind of thing in the first place.

But no amount of maintenance will eliminate the possibility of malfunction. So when your furnace is leaving you cold, here’s what you need to know:

What causes a furnace or heating system to blow cold air?

As furnace malfunctions go, blowing cold air is quite noticeable. The silver lining is that it won’t go unnoticed for very long – which can hasten your repair schedule.

On the other hand, a lot of different things can cause your heater to behave this way. So even though you definitely have a problem, the solution isn’t going to present itself as easily.

The number of potential culprits also makes cold air a tricky problem to diagnose. That’s why you should be thinking about calling for a free inspection and a no-obligation estimate from Metro Energy Savers.

In this article, however, we will cover a few of the likeliest causes, so you have some idea of what you’re dealing with.

  1. Thermostat error.

Welcome to your best-case scenario.

If your thermostat – which is the brain of your system – isn’t sending the correct signals, your furnace will misbehave. That could mean that it’s blowing cold air because it’s being told to, not because it can’t generate heat.

User error would be welcome if slightly embarrassing cause. So start there. Make sure your thermostat is set to AUTO or HEAT, and that the temperature is set correctly (and to your preference between Fahrenheit and Celsius). If your system gets kicked into FAN mode, you’re not going to feel any warmer.

If your settings are right on the money, your thermostat might be on the fritz. Make sure it’s located correctly in your home, not near a cold draft or a particularly sunny window, which could throw off the temperature reading.

Most modern thermostats will allow for a reset to try and kick things back into gear. But even if your thermostat is beyond saving, you’re not going to break the bank on a replacement.

  1. Ductwork

Is your cold air problem only in parts of the house?

If so, ductwork could be to blame. If your thermostat is the brain, your ducts are the circulatory system, carrying the air where it needs to go. If a duct has developed a leak or been knocked loose somehow, it can’t perform properly.

Usually, when that happens, you’ll only get cold air in rooms that are after the leaky section of the duct in the home’s airflow.

Fixing and replacing ducts is simple enough for the professionals. As furnace repair prices go, this one isn’t necessarily a killer, unless it’s an extreme case. When it comes to ductwork, a lot of the expense is tied to work hours.

And even in cases of serious duct repair, it’s going to be cheaper than replacing a damaged or malfunctioning system in most cases.

Heating Repair Arlington: What if it’s something with my actual furnace?

  1. Air filters

Whether you’re in Arlington or the Arctic, air filters are a necessary component of a good heating and cooling system.

By far the most common source of issues is dirty air filters. They’re easy to neglect and extremely important. If your furnace is blowing cold air, you can swap these and see if it helps.

Failure to clean or replace air filters leads to poor airflow. When airflow is restricted in that way, the furnace can begin to short cycle or overheat. Furnaces have a lot of safety controls built-in, so before they can overheat, they’ll most likely simply shut down.

However, with many furnaces, the blower will continue to operate. They’ll just be blowing lukewarm and progressively cooler air.

Your fix is a breeze, though: swapping the filters and restarting the system. That could really be all it takes.

Or …

  1. Pilot light and igniter

If your pilot light goes out or your ignition stops functioning, your furnace won’t generate any heat. With older furnaces, this can be dangerous. Most carbon monoxide leaks start this way.

Modern furnaces often have a safety shutoff to prevent gas leaks, but if your pilot or ignition is down, call our emergency line immediately. We’ll get on the scene as fast as possible, confirm your safety, and work to restore your heat.

  1. Condensate drain

Modern furnaces are very efficient. They have drain lines to remove all the moisture and water created during the heating process. This helps keep your house from becoming far too humid and discourages mold.

When that drain line is clogged, it usually triggers a shutoff that prevents your burners from lighting. Your system will blow cold air if that’s the case.

Any furnace repair technician from Metro Energy Savers can clear your condensate line and empty your drain for you. It’s a standard part of our tune-up service. It’s good to have this handled quickly, though, before trouble mounts!

Furnace Repair Troubleshooting

We respect the DIY spirit, but please keep in mind that furnaces deal with high voltage and combustibles. It’s not something we recommend for an untrained homeowner.

For anything more complex than filter changes and thermostat troubleshooting, it’s best to get a professional’s advice.

If you’re in Arlington, Fort Worth, or anywhere else in the Mid-Cities area, give us a call. We can handle all of your heating repair needs.
