Five Reasons Why Your Air Conditioner Isn't Cooling Your House

July 10, 2020

When it’s a scorching summer day in Huffman, nothing feels worse than figuring out your HVAC isn’t operating the way it is meant to. The last thing you want to do is request air conditioner repair. But your AC is an exceptionally complicated system, so it can be almost impossible to find out what’s triggering the trouble all alone.

That’s why Air Houston Mechanical LLC wrote this handbook to help you understand what could be happening with your cooling system. Here, you’ll learn some everyday reasons your home is feeling a little too warm. And even though a couple of these are fairly painless DIY tasks, you might want to bring in an expert for AC repair.

And if need help, Air Houston Mechanical LLC is ready to assist. Here are five reasons why your air conditioner may not be cooling your home in Huffman.

1. Your System Settings May Be Incorrect

Every home adjusts their thermostat a bit differently to suit their specific preferences. Nevertheless, many households make the misstep of setting their thermostat to “On” rather than “Auto.” With this setting, the fan in your HVAC system will continue to produce an air current even when you’ve reached your set temperature.

This can feel like your vents are distributing room temperature air, when in fact it’s only using the fan more frequently than necessary. Change this setting and find out if things cool off.

2. Your Air Conditioner Needs a Routine Cleaning

There are two central areas to check for dirt or dust accrual when your home comfort system doesn’t appear to be working as it should.

Before anything else, inspect your system’s filter. If you don’t switch out your filter regularly, built-up dust can make it hard for air to move through and cool down your home. If your filter is clearly dirty or dusty, it’s more than likely time for a change. (And in general, you have to switch it about once every three months at least.)

If your filter is looking good, move to your external unit. See if there’s a reasonable amount of clearing around it and clear any plants or litter stuck there. This section of your cooling system lets off the heat from inside your rooms. If the coils outside are clogged, you won’t be feeling cool in your home.

We advise booking professional air conditioner maintenance every year to keep your system working properly and to keep your warranty valid.

3. Your Unit is Releasing Refrigerant

Refrigerant is the chemical that cools the air in your home. It runs between your indoor and outdoor units to soak up and discharge heat, to help your rooms get cool. If there is a break somewhere, you won’t be comfortable again until you schedule professional air conditioning repair.

Signs of a refrigerant leak include a decrease in chilled air, higher power bills, frozen evaporator coils and unusual hissing noises coming from your AC.

If you think refrigerant may be leaking, call Air Houston Mechanical LLC for HVAC repair as soon as possible. Refrigerant can also be harmful to your family’s health.

4. One or More Pieces Need to Be Replaced

Your AC contains a couple important elements. These include the blower, evaporator coils, compressor, fan, condenser coils and expansion valve. If any part is broken, your home comfort suffers.

Our Air Houston Mechanical LLC pros are well-trained and knowledged in HVAC. They can help you find and mend any issue.

5. Your System Should Be Replaced

If your equipment is upward of 10 years old, it may be time to think about new air conditioner installation. As your system gets older, it simply won’t work as well as it did when it was new. And it might be making your place feel unpleasant.

If your AC is on the younger side but still isn’t properly cooling your home, it may be the wrong size for your space. HVAC systems are not all the same size. A system that’s not powerful enough simply can’t chill a house the way an accurately sized AC can.
