How to Know If Your HVAC Isn’t Working

If you’re heating and/or cooling systems are not working, you are not the only one. In fact, you may be joining a large group of your neighbors who also have had breakdowns in the middle of a hot summer or cold winter night.

While this may seem like a minor inconvenience, remember that you depend on your heating and cooling systems to keep your home livable and comfortable. It is important to recognize when your systems are not working correctly and to take action to get them back up and running as soon as possible.

When you have a problem with your HVAC system, you can’t just take it into the repair shop. You need to be able to identify what the problem is and the best way to do this is by checking your vents. If your vents are cold, then you have a problem with your fan, or your fan is not blowing hard enough to keep your home cool.

Here are the signs that you’re HVAC needs a repair:

  • Warm Air

Let’s face it. The weather outside is frightful. What can you do? The first step is to figure out what’s actually happening with your heating system. The heat that doesn’t seem to be coming out of your vents might be an easy fix, or it might be a sign of a much larger problem.

Before we get on with this article, we should note that this problem isn’t always easy to spot. In fact, you might be thinking that everything is running fine, but when you’re hot and tired at night, you can’t seem to get to sleep. The best way to identify this problem is to check the thermostat.

If it’s set to a lower temperature than it was when you turned it up in the daytime, there is a good chance that your system is in a state of distress.

  • Lack of Airflow

If you have cold air blowing out of your vents and the furnace is running, you might think everything is fine. But if you’re not getting a good stream of cool air, you might want to check the airflow in your home. Airflow is a measurement of the amount of air moving through your ducts.

Airflow is the key to a healthy home. When you have sufficient fresh air coming into your home, you won’t suffer from stuffy noses, allergies, or respiratory problems.

In addition, you’ll be able to save on your energy bills since you won’t have to run your air conditioning as much. Unfortunately, bad airflow can lead to some serious problems if you aren’t careful.

  • High Humidity

Humidity is a general term for the amount of water vapor in the air. High humidity can make it feel more difficult to breathe, cause you to feel warmer, and prevent your body from cooling down. If you live in a humid climate, you may notice that your skin feels damp and that your clothes stick to your body.

As we move into the summer months, it’s important to know your way around home air conditioning systems. One of the first things to know is that your home’s relative humidity should end up between 30 and 50 percent. If you have a damp basement, or your bathroom gets steamy when you take a hot shower, you probably have a lot of humidity in your house. If you’re experiencing this problem for the first time, it’s best to consult a professional on how to fix it.

  • Bad Odors

Odors are a natural part of life. After all, our own bodies have them, but we don’t generally notice them. However, when it’s your house that smells, it’s a different story. Most odors are caused by bacteria, mold, mildew, or fungi that feed on the organic materials in your home. In addition to being unpleasant, these materials can cause problems if you are allergic to them.

  • Unusual Noise

While a home’s HVAC system is designed to keep your family comfortable and reduce your energy bills, it’s also a machine that produces many different types of moving parts that can make all kinds of different noises. From the steady hum of the unit running to the whooshing of ductwork during circulation, HVAC noise can be both a source of comfort and a source of stress. How can you tell if a noise is something to be concerned about? Generally, it’s a good idea to contact a professional if you hear any of the unusual sounds.
