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

July 10, 2020

When it’s a warm summer day in Shelby, nothing is worse than figuring out your cooling system isn’t performing the way it is supposed to. The last thing you should have to do is schedule cooling system repair. But your air conditioner is an incredibly involved system, so it can be challenging to discern what’s causing the issue solo.

That’s why Hopper Heating and Air made this guide to help you see what may be going on with your AC. From here, you’ll find some typical explanations for why your home is feeling a little too warm. And though a couple of these are fairly painless DIY activities, you could want to call in a professional for HVAC repair.

And if need help, Hopper Heating and Air is here for you. Here are five reasons why your air conditioner may not be cooling your home in Shelby.

1. Your Thermostat Settings Could Be Incorrect

Everyone uses their thermostat a touch differently to fit their particular needs. Nevertheless, many households make the mistake of setting their thermostat to “On” instead of “Auto.” Under this setting, the fan in your system will continue to blow even when you’ve reached your set temperature.

This can appear like your ducts are pushing out warm air, when in reality it’s only employing the fan more frequently than needed. Try switching this setting and determine if things cool off.

2. Your HVAC Needs a Routine Cleaning

There are two primary areas to examine for dirt or dust collection when your HVAC doesn’t feel like it is performing correctly.

First off, inspect your HVAC filter. If you don’t swap out your filter routinely, buildup can make it more difficult for air to travel through and cool your home. If your filter is noticeably dirty or dusty, it’s probably time for a substitute. (And in general, you need to replace it about once every three months at a minimum.)

If your filter seems fine, move to your outdoor unit. Find out if there’s a reasonable amount of room around your air conditioner and clear any plants or dirt close by. This section of your AC lets out the heat from inside your house. If the coils outside are closed off, you won’t be cool in your home.

We recommend scheduling professional air conditioner maintenance yearly to keep your unit running smoothly and to keep your warranty valid.

3. Your System is Leaking Refrigerant

Refrigerant is the component that cools down the air in your house. It goes between your inside and outside units to soak up and let off heat, to help your space keep comfortable. If there is a leak along that system, you won’t be feeling comfortable again until you schedule professional air conditioning repair.

Indications of a refrigerant leak include a decrease in conditioned air, larger utility bills, frozen evaporator coils and unusual hissing noises originating from your air conditioner.

If you think refrigerant could be leaking, call Hopper Heating and Air for air conditioner repair as soon as possible. Refrigerant can also be hazardous to your family’s health.

4. One or More Elements Need to Be Replaced

Your AC contains a few key pieces. These include the blower, evaporator coils, compressor, fan, condenser coils and expansion valve. If one of these is failing, your home comfort will suffer.

Our Hopper Heating and Air pros are well-trained and experienced in HVAC. They can help you diagnose and mend any issue.

5. Your AC Has to Be Upgraded

If your system is over 10 years old, it is probably about time to look into new air conditioner installation. As your system ages, it just won’t run as well as it has in the past. And it might be making your house feel unpleasant.

If your system is more current but still isn’t cutting it, it may be the wrong size for your household. HVAC systems are not all the same size. An air conditioner that’s not powerful enough just can’t chill a place the way an accurately sized HVAC can.
