Why Can’t I Keep My House Cool/Warm?

It’s frustrating after a while – your thermometer is set to a perfect temperature, but you still feel really uncomfortable. You’re left wondering “why can’t I keep my house cool/warm?”

There are some simple solutions that might be standing between you and an ideal temperature. In this article, we’ll talk all about it and give you plenty of reasons why your home can’t stay at the right temperature.

Possible Reasons Your Home Won’t Stay Cool

The biggest complaint in South Carolina is a home that’s too warm and uncomfortable. They say “if you can’t take the heat, get out of the kitchen”, but what happens when every other room is just as hot?

We have some harsh summers, and lots of people can’t keep their homes cool. You’ve got your AC set at a low temperature and every fan in the house is turned on – and it’s still hot. Assuming your windows and doors are closed, something is probably wrong. Here are some of the biggest culprits.

With most of the country on stay-at-home orders, it is more important than ever to make sure that our immediate environments are safe.

Home Needs More Insulation

Once the cold air is in your house, you don’t want it escaping. If your home is poorly insulated, you’re in trouble. Insulation is how well a material can stop temperatures from traveling through them. Poorly insulated windows, attics, crawl spaces or walls will allow your home’s cool air to escape. You’re left with a system that can’t keep your house cool.

How do you add insulation? It’s a little harder after your home is built. You can put up extra insulation in your attic or crawlspace, add thick curtains, or add some cavity wall insulation. We do feel it is important to note, due to the high amount of VOC’s found in it, we do not recommend using spray foam insulation.

Air Conditioning Needs Maintenance

Your air conditioning system needs preventative maintenance from time to time. As they run, they’ll clog, or get debris in the system. This will slow down your system over time and can even lead to failure.

The good news is that our team is here to perform routine maintenance to keep your AC working properly. Our pros know where to look and what to do to optimize your air conditioning unit. But if you know it’s not your unit causing the issue, then maybe humidity is to blame.

High Humidity

If you have read our blogs, you know humidity is an extremely important factor in comfort. If your home’s humidity is too high, you could feel much hotter even when the air’s temperature is at a comfortable level.

It slows down your body’s ability to regulate heat. On top of that, humidity can ruin your home’s indoor air quality. If your home feels sticky, you can blame high humidity. You might just need a dehumidifier to correct the problem.

Leaky Ducts

A simple duct leak is estimated to drop your HVAC’s efficiency by up to a third. Your system will cool down the air, but it will escape through the ducts before it gets to your home.

Not great. You might think this is where duct tape comes in handy, but it’s not that easy. You’ll need a team of pros to help. Our team can repair your AC system if there’s a leaky duct, and you’ll be feeling the cool air again in no time. We can also check out your outdoor equipment while we’re there.

If water droplets containing the bacteria are sucked into the HVAC system, they can be pushed back out into the common indoor environment

Debris in Outdoor Equipment

The problem with outdoor HVAC equipment is that dust and debris love building up in it. After some time, you’ll wind up with a dust-clogged outdoor unit. The fan will have to work harder, and you might not get enough airflow through your system. This leads to a whole host of problems – one of which is a home that doesn’t get cool enough. Rinse your outdoor equipment with a hose or run a vacuum over it to try to fix the problem, otherwise, let us take a look.

Old A/C Systems Needs to Be Replaced

The sad news is that your A/C system won’t last forever. That’s right, even a well-maintained HVAC unit will eventually need to be replaced. This might be the culprit for why your home won’t get cold. A simple AC replacement from our pros at Carolina Comfort can get you back to normal in no time. Now let’s talk about the opposite problem – houses that don’t get warm.

Possible Reasons Your Home Won’t Stay Warm

Here in South Carolina, your HVAC unit probably takes care of both the cooling and the heating. All of the issues outlined above can also be the reason why your home won’t stay warm. Especially a poorly insulated home.

Need Help Keeping Your Home Cool/Warm?

It’s one thing to recognize why you can’t keep your house cool/warm, but it’s another thing to correct the problem. Some of the items that we listed above simply can’t be fixed by an everyday person. You need an HVAC professional. At Carolina Comfort, our goal is to help you keep your home at the perfect temperature year-round. If you want some help, give us a call or email us today.
