One nice thing about living in Missouri? Our winters aren’t all that extreme. Just because they’re not extreme doesn’t mean that you don’t have to worry about keeping your home warm and cozy throughout the winter season, though. There are plenty of cold temperatures and a decent amount of snowfall around here in the winter season. You need to know that your heater is ready for action when that time of the year arrives. And that simply won’t be the case if you fail to handle any necessary heater repairs in O’Fallon, MO, promptly.
Today, we’re going to talk about a fairly common issue that homeowners encounter—a furnace blowing cool air. The fact that it’s not an uncommon issue doesn’t make it any less infuriating. Don’t take any chances with the condition of your furnace, your comfort, or your safety. The moment that you realize there is a problem with your heater is the moment that you should be calling us to schedule repairs.
The Best-Case Scenario—Check the Thermostat
We’ve all had those moments. You slap your forehead, wondering how you could have missed something so obvious. Don’t sweat it.
Lots of homeowners have sounded the alarm over furnaces blowing cool air, only to realize they set the thermostat wrong.
No, we don’t mean they set so low a temperature that the furnace is actually cooling air. A furnace can’t do that. What it can do, however, is just run the fan. And if you have the thermostat set to a fan-only mode, then that is all that you can expect the system to do!
How’s Your Ductwork Holding Up?
For most homeowners, the answer to that question is probably: uh, fine, I guess?
And that’s fine!
You’re not HVAC professionals. There is very little chance that you’re thinking about your air ducts all that frequently. However, they are actually a pretty common source of trouble. If your ducts are not well-sealed, then they can allow heat to escape from the system into cooler, unconditioned spaces in the house. When that happens, the air coming from your vents is not going to be as warm as it should be.
That not only drives down your comfort. It also drives up your energy costs. And if there’s anything worse than overpaying for your comfort, it’s overpaying for too little of it! Professional duct sealing is the only way to go here.
You May Have a More Serious Problem
If your system is not able to combust fuel or generate heat with electric resistance safely, it can actually shut down the heat generation part of its operation to protect you. A very dirty air filter could activate the limit switch, which is a very easy fix—you just need a fresh filter. However, if you have an issue with gas combustion and your system isn’t burning fuel as a result, you may be stuck with a furnace that is really little more than a fan.
Don’t ever take any chances with the safety of your furnace’s operation.
