When it’s a hot summer afternoon in Rock Hill, nothing could be worse than realizing your AC isn’t performing the way it is supposed to. The last thing you should have to do is schedule air conditioner service. But your air conditioner is a quite complex system, so it can be hard to determine what’s causing the issue on your own.

That’s why US Air Heating and Cooling made this handbook to help you find out what might be taking place with your home comfort system. From here, you’ll discover some typical situtations that explain why your house is feeling uncomfortable. And though a couple of these are easy] DIY projects, you could need to bring in a skilled technician for AC repair.

And if you need us, US Air Heating and Cooling is here for you. Here are five reasons why your air conditioner may not be cooling your residence in Rock Hill.

1. Your Thermostat Settings Are Off

Every family sets their thermostat a little differently to suit their specific preferences. Yet, a number of people make the error of setting their device to “On” as opposed to “Auto.” With this setting, the fan in your system will continue to blow even after you’ve achieved your set temperature.

This can feel like your AC is pushing out warm air, when in reality it’s just utilizing the fan on a more regular basis than necessary. Change this setting and work out if things change.

2. Your System Needs to Be Cleaned

There are two main areas to check for dirt or dust buildup when your air conditioner doesn’t feel like it is operating correctly.

Before anything else, examine your HVAC filter. If you don’t switch your filter often enough, built-up dust can make it more difficult for air to flow through and cool your house. If your filter is noticeably dirty or dusty, it’s likely time for a change. (And as a rule, you need to replace it about once every three months at least.)

If your filter is looking fine, move to your outdoor unit. Double check there’s a reasonable amount of clearing around it and clear any plants or debris close by. This part of your cooling system lets off the heat from inside your home. If the coils outside are blocked, you won’t be comfortable inside.

We advise setting professional air conditioner maintenance every year to keep your unit running smoothly and to keep your warranty valid.

3. Your System is Leaking Refrigerant

Refrigerant is the material that conditions the air in your house. It moves between your indoor and external units to absorb and let off heat, to help your space remain the right temperature. If there is an opening along that system, you won’t be cool again until you schedule professional air conditioning repair.

Signals of a refrigerant leak include a lack of conditioned air, pricier electric bills, frozen evaporator coils and odd hissing noises arising from your air conditioner.

If you suspect refrigerant might 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 Elements Need to Be Replaced

Your AC contains a a handful of crucial parts. These include the blower, evaporator coils, compressor, fan, condenser coils and expansion valve. If one of these is failing, your home comfort is hurt.

Our US Air Heating and Cooling technicians are trained and skilled in all areas of HVAC. They can help you find and fix any problem.

5. Your System Has to Be Replaced

If your AC is more than 10 years old, it could likely be a good time to look into new air conditioner installation. As your system gets older, it simply won’t function as well as it once did. And it could be making your house too warm.

If your air conditioner is more current but still isn’t cooling things off, it might be the wrong size for your house. HVAC systems are not one-size-fits-all. An AC that’s undersized absolutely can’t help a home the way an appropriately sized air conditioner can.
