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

July 10, 2020

When it’s a hot summer day in Hodgenville, nothing is worse than realizing your HVAC isn’t performing the way it should. The last thing you want to do is call for AC service. But your HVAC is an incredibly involved system, so it can be hard to deduce what’s creating the problem by yourself.

That’s why Phelps Heating & Cooling made this handbook to help you find out what might be happening with your AC. From here, you’ll learn a couple prevailing situtations that explain why your space is feeling a little too warm. And though some of these are straightforward DIY projects, you could need to find a professional for air conditioner repair.

And if need help, Phelps Heating & Cooling is prepared to take care of your home. Here are five reasons why your air conditioner may not be cooling your residence in Hodgenville.

1. Your Thermostat Settings May Be Incorrect

Every person adjusts their thermostat a bit differently to fit their particular needs. However, a number of people make the error of setting their thermostat to “On” as opposed to “Auto.” Under this setting, the fan in your system will continue to produce an air current even once you’ve gotten to your preferred temperature.

This can come off like your ducts are distributing warmish air, when in fact it’s simply employing the fan more often than required. Swap this setting and see if things seem better.

2. Your HVAC Needs Some Cleaning

There are two central places to investigate for dirt or dust accumulation when your cooling system doesn’t appear to be operating as it should.

First, check out your AC system’s filter. If you don’t replace your filter often enough, accumulated dirt can make it hard for air to move through and cool your house. If your filter is obviously dirty or dusty, it’s probably time for a change. (And for best operation, you should replace it about once every three months at the very least.)

If your filter seems good, head to your external unit. See if there’s a reasonable amount of room around the unit and sweep away plants or litter around it. This piece of your AC lets out the heat from inside your space. If the coils outside are blocked, you won’t be comfortable in your home.

We advise scheduling professional air conditioner maintenance every year to keep your system running like it should and to keep your warranty valid.

3. Your System is Losing Refrigerant

Refrigerant is the stuff that chills the air in your house. It moves between your inside and external system pieces to soak up and discharge heat, to help your home stay comfortable. If there is a crack somewhere, you won’t be comfortable again until you set professional air conditioning repair.

Indicators of a refrigerant leak include a decline in cooled air, more expensive energy charges, frozen evaporator coils and unusual hissing noises originating from your air conditioner.

If you are worried refrigerant may be leaking, call Phelps Heating & Cooling for HVAC 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 is made up of a few key parts. These include the blower, evaporator coils, compressor, fan, condenser coils and expansion valve. If one part is broken, your home comfort is hurt.

Our Phelps Heating & Cooling technicians are trained and experienced in HVAC. They can help you figure out and mend any trouble.

5. Your Air Conditioner Has to Be Replaced

If your air conditioner is more than 10 years old, it is probably time to look into new air conditioner installation. As your system puts on the years, it unfortunately won’t run as well as it did when it was new. And it may be making your place less comfortable.

If your air conditioner is on the younger side but still isn’t keeping you cool, it might be undersized for your home. HVAC systems are made in different sizes. An air conditioner that’s undersized simply can’t help a place the way a properly sized AC can.
