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

When it’s a scorching summer day in Rock Hill, nothing feels worse than realizing your air conditioner isn’t performing the way it was built to. The last thing you need to do is call for AC help. But your HVAC is a quite complicated system, so it can be hard to determine what’s creating the problem all alone.

That’s why US Air Heating and Cooling wrote this handbook to help you understand what might be taking place with your air conditioner. From here, you’ll find some typical reasons your home is feeling uncomfortable. And while a few of these are fairly painless DIY projects, you could need to turn to a skilled technician for AC 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 home in Rock Hill.

1. Your System Settings May Be Incorrect

Every person adjusts their thermostat a little differently to work with their personal needs. Despite that, many people make the mistake of setting their thermostat to “On” as opposed to “Auto.” Because of this setting, the fan in your system will continue to blow even after you’ve attained your desired temperature.

This can appear like your ducts are releasing untreated air, when in reality it’s only employing the fan more often than required. Try switching this setting and see if things seem better.

2. Your Cooling System Needs a Good Cleaning

There are two principal areas to inspect for dirt or dust buildup when your HVAC doesn’t seem to be functioning correctly.

First, check out your HVAC filter. If you don’t swap out your filter routinely, built-up dust can make it more labor intensive for air to pass through and cool your space. If your filter is obviously dirty or dusty, it’s likely time to replace it. (And as a rule, you need to switch it about once every three months or more frequently.)

If your filter is looking good, move to your outside unit. Find out if there’s a reasonable amount of clearing around your air conditioner and clean up plants or debris stuck there. This element of your AC releases the heat from inside your house. If the coils outside are clogged, you won’t be comfortable indoors.

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

3. Your Unit is Releasing Refrigerant

Refrigerant is the stuff that conditions the air in your home. It cycles between your inside and outside units to grab and let off heat, to help your house stay cool. If there is a crack along that path, you won’t be cool again until you book professional air conditioning repair.

Signs of a refrigerant leak include a decrease in chilled air, more expensive electric charges, frozen evaporator coils and strange hissing noises arising from your HVAC.

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

4. One or More Parts Should Be Replaced

Your cooling system includes a a handful of crucial elements. These include the blower, evaporator coils, compressor, fan, condenser coils and expansion valve. If any one of these is failing, your home comfort declines.

Our US Air Heating and Cooling pros are well-trained and knowledged in HVAC. They can help you figure out and mend any issue.

5. Your Whole System Has to Be Updated

If your system is more than 10 years old, it may be a good time to consider new air conditioner installation. As your system puts on the years, it sadly won’t function as well as it has in the past. And it might be making your space less comfortable.

If your HVAC unit is on the younger side but still isn’t properly cooling your home, it might be too small for your household. Air conditioners are not all the same size. A system that’s not powerful enough absolutely can’t chill a place the way a correctly sized system can.
