Learning About HVAC Equipment

Have you noticed that your air conditioner has been blowing hot air lately? If so, then this is a cause for concern. After all, your air conditioner's sole purpose is to condition your indoor spaces, not make your home hotter. Fortunately, there are a few things that AC repair services can do to fix this problem. Read along to learn what this means and why you should commission AC repair.

1. Dirty or Worn-Out Air Filters

One of the major causes of an air conditioner blowing hot air is dirty or worn-out air filters. Over time, the filters in your AC unit will become clogged with dirt and debris. This can restrict airflow and prevent your equipment from cooling your indoor spaces. Fortunately, this is an easy problem to fix; your AC technician will clean the air filters to restore proper airflow. However, if the professionals realize the air filters are too worn-out, they will help you purchase the right type of filter for your unit.

2. Low Refrigerant Levels

If your AC unit is low on refrigerant, it will also blow hot air. This is because the refrigerant is what helps to cool the air in your home, so if there isn't enough of it, the unit won't be able to fulfill its role.

This is a much more serious problem than it looks on the surface because your refrigerant isn't supposed to leak. Not unless one of the components it flows through is cracked. That's why the professional will begin by fixing the cracks before refilling the refrigerant. And once more refrigerant is added to the unit, it should start blowing out cold air again.

3. Inspecting the Evaporator Coils

If your AC unit's evaporator coils are frozen, it will also blow hot air. The freezing of evaporator coils is usually caused by a lack of airflow over the coils. To fix this problem, an AC technician will need to inspect the coils and make sure that they are not blocked. Once the coils are clear, the problem should be resolved.

4. Addressing Ductwork Leaks

Another common cause of insufficient indoor cooling is leaky ductwork. If there are leaks in your air ducts, they can cause some of the cool air to escape before reaching your home. If you've noticed that your AC unit has been blowing hot air, contact an AC repair technician immediately. They will be able to diagnose the problem and get it fixed so that you can have cool, comfortable air in your home again.

These are some reasons why your AC unit may be blowing hot air. If you're experiencing this problem, then don't hesitate to contact AC repair services. The professionals will diagnose the problem and get it fixed so that you can have cool, comfortable air in your home again.
