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

July 10, 2020

When it’s a hot summer day in Rapid City, nothing feels worse than realizing your air conditioner isn’t functioning the way it was built to. The last thing you need to do is request HVAC service. But your HVAC is an exceptionally involved system, so it can be challenging to figure out what’s triggering the trouble all alone.

That’s why Precision Mechanical created this informational guide to help you understand what could be taking place with your AC. Here, you’ll find some prevailing reasons your family is feeling uncomfortable. And while some of these are fairly painless DIY tasks, you might have to turn to a pro for cooling system repair.

And if need help, Precision Mechanical is prepared to take care of your home. Here are five reasons why your air conditioner may not be cooling your home in Rapid City.

1. Your Device Settings May Be Off

Every person adjusts their thermostat a bit differently to match their particular needs. Despite that, many homeowners make the mistake of setting their device to “On” rather than “Auto.” Under this setting, the fan in your AC will continue to push out air even after you’ve gotten to your set temperature.

This can feel like your ducts are distributing room temperature air, when in fact it’s just utilizing the fan more often than needed. Adjust this setting and see if things seem better.

2. Your System Needs Some Cleaning

There are two primary places to examine for dirt or dust accrual when your HVAC doesn’t seem to be performing well.

First off, take a look at your AC system’s filter. If you don’t replace your filter on a regular basis, built-up dust can make it more difficult for air to move through and lower the temperature your home. If your filter is visibly dirty or dusty, it’s probably time for a change. (And as a rule, you need to change it about once every three months at least.)

If your filter is looking clean, head to your external unit. Double check there’s adequate space around your air conditioner and clear away plants or dirt stuck there. This part of your AC discharges the heat from inside your space. If the coils outside are closed off, you won’t be cool indoors.

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

3. Your Unit is Releasing Refrigerant

Refrigerant is the component that cools down the air in your home. It moves between your internal and outside units to absorb and let off heat, to help your home get the right temperature. If there is a break along the way, you won’t be cool again until you set professional air conditioning repair.

Indicators of a refrigerant leak include a lack of cooled air, larger electric bills, frozen evaporator coils and strange hissing noises coming from your system.

If you feel refrigerant may be leaking, call Precision Mechanical for HVAC repair as soon as possible. Refrigerant can also be damaging to your family’s health.

4. One or More Elements Should Be Replaced

Your air conditioner includes a few important pieces. These include the blower, evaporator coils, compressor, fan, condenser coils and expansion valve. If any one of these is failing, your home comfort is hurt.

Our Precision Mechanical technicians are well-trained and skilled in all areas of HVAC. They can help you locate and fix any trouble.

5. Your AC Has to Be Updated

If your air conditioner is upward of 10 years old, it could likely be about time to look into new air conditioner installation. As your system gets up there in years, it unfortunately won’t work as well as it did in the beginning. And it might be making your home too warm.

If your air conditioner is on the younger side but still isn’t cooling things off, it could be too small for your home. AC units are not one-size-fits-all. An air conditioner that’s too small absolutely can’t chill a house the way a correctly sized HVAC can.
