Reasons why your AC might be blowing off hot air

In Houston, your dependency would increase on your air conditioning unit as the summer approaches. With the average temperatures staying at 80-90 degrees Fahrenheit, switching off the AC will not even be an option.

In such high temperatures, it is almost impossible to live in a house without an AC. However, using your AC non-stop can also lead to issues.

It could be very uncomfortable if you walk into your home and the air conditioning is not working effectively to cool down the room. The scorching heat and humidity could make it very difficult for you to live at home.

So, if any such things happen with you during the hot Houston summer, you must contact a repair company that provides 24 hour ac repair houston.

However, here are some common reasons why your AC must be blowing hot air.

  1. Incorrectly calibrated thermostat

Often, you might set up the thermostat or the settings so that it is on the blower setting. When a thermostat is set on blower mode, your AC will just send out regular air instead of cooled air.

You can try changing the settings on your thermostat. If it doesn’t work, you could consider turning it off and on. For more help, refer to the instruction manual.

  1. Return vents are closed

At the top of the interior unit of the AC, there is an intake that sucks in the air for the heat exchange process. If this intake vent is being locked by anything, the hot air will stay inside your room, rendering your AC useless.

At times, people may forget to reopen the return vents after winter, so if you find it abnormally warm in the house, check if your return vents are closed.

  1. Dirty evaporator coil

The evaporator coils of the air conditioner hold the refrigerant gas inside. When the air from the unit’s fan blows over the coils, the chilled refrigerant conducts the heat exchange process to cool down the space. During this process, condensation happens as a by-product.

During this process, the moisture gets collected on the coils, making them more prone to dirt and debris. Over time, as a lot of dirt gets built up on coils, the air conditioning uses its cooling ability. If the water collected on the coil is not taken care of timely, then it might even cause the coils to freeze over.

  1. Fan problems

The outdoor unit of the conditioning system transfers the indoor heat outside your home. There are many reasons why the fan could not be working properly, and it could hinder the heat transfer process. If the conditioning unit cannot expiate heat, it could throw warm air into your home.

If you suspect an issue with your fan, you may want to call a professional AC repair technician to examine your unit. They will be able to identify the issue and recommend the next steps.

  1. Dirty Air filter

This is yet another reason the AC could give off warm air. Dust and debris may get into the airflow intake’s filter to clog the whole mechanism. It is a small problem that you can fix by yourself. You can visually inspect the air filter, and if there is a lot of debris, you can clean it off.

These are some common reasons why your AC might not be working properly. If you cannot find out the issue yourself, you must contact an AC maintenance company that provides 24-hour AC repair in Houston. They will be able to send over a professional to inspect your unit, identify the problem and suggest the next steps.
