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

July 10, 2020

When it’s a hot summer morning in Rock Hill, nothing could be worse than figuring out your AC isn’t performing the way it should. The last thing you want to do is schedule cooling system repair. But your air conditioner is a pretty complicated system, so it can be challenging to discover what’s causing the trouble all alone.

That’s why US Air Heating and Cooling made this informational guide to help you find out what may be happening with your cooling system. Here, you’ll discover a couple common explanations for why your place is feeling a little unpleasant. And while a couple of these are easy DIY projects, you might have to bring in a skilled technician for home comfort system repair.

And if you do, US Air Heating and Cooling is ready to assist. Here are five reasons why your air conditioner may not be cooling your residence in Rock Hill.

1. Your Device Settings Could Be Incorrect

Everyone uses their thermostat a little differently to suit their individual needs. Even so, a lot of families make the misstep of setting their thermostat to “On” rather than “Auto.” Under this setting, the fan in your air conditioner will continue to blow even once you’ve reached your desired temperature.

This can appear like your AC is releasing warmish air, when in fact it’s just using the fan on a more regular basis than needed. Swap this setting and find out if things cool off.

2. Your System Needs a Routine Cleaning

There are two central areas to examine for dirt or dust accumulation when your home comfort system doesn’t appear to be performing right.

Firstly, take a look at your system’s filter. If you don’t switch out your filter often enough, accumulated dirt can make it hard for air to travel through and cool down your space. If your filter is obviously dirty or dusty, it’s more than likely time to replace it. (And in general, you have to replace it about once every three months at the very least.)

If your filter is looking good, go to your outdoor unit. Find out if there’s a reasonable amount of room around it and sweep away plants or dirt stuck there. This part of your AC lets out the heat from inside your space. If the coils outside are clogged, you won’t be feeling comfortable in your home.

We recommend setting professional air conditioner maintenance each year to keep your system operating properly and to keep your warranty valid.

3. Your Unit is Leaking Refrigerant

Refrigerant is the chemical that cools the air in your house. It cycles between your inside and outside system pieces to grab and let off heat, to help your rooms stay cool. If there is a break somewhere, you won’t be cool again until you book professional air conditioning repair.

Signs of a refrigerant leak include a lack of treated air, larger monthly bills, frozen evaporator coils and strange hissing noises originating from your HVAC.

If you are worried refrigerant might be leaking, call US Air Heating and Cooling for AC repair as soon as possible. Refrigerant can also be damaging to your family’s health.

4. One or More Elements Have to Be Replaced

Your cooling system contains a a handful of important elements. These include the blower, evaporator coils, compressor, fan, condenser coils and expansion valve. If one of these is not working, your home comfort is hurt.

Our US Air Heating and Cooling technicians are trained and knowledged in HVAC. They can help you locate and mend any problem.

5. Your AC Has to Be Replaced

If your AC is older than 10 years old, it could likely be about time to think about new air conditioner installation. As your system puts on the years, it simply won’t run as well as it did when it was new. And it could be making your space less comfortable.

If your system is more current but still isn’t cutting it, it could be too small for your living space. Air conditioners are not all the same. A cooling system that’s too small absolutely can’t cool a space the way a properly sized air conditioner can.
