Can’t Figure out Why the AC Isn’t Keeping the House Cool?

acservices

Windows are closed. Doors are closed. Air conditioning is on. The thermostat is set at a nice, cool setting. All utility bills are paid. So why isn’t the air conditioning cooling?

At one time or another, most of us have come home to a hot house and a running air conditioner and have gone through the checklist above. It’s frustrating when your system is running and should be cooling, yet the house is hot.

While there are a number of things that can cause this, in most cases it means that you’re in need of AC services. Today we’ll talk about some of the most common issues that result in your system not cooling properly.

Your Unit is Low on Refrigerant

lowrefrigerantYour air conditioner has to have refrigerant to work. One common cause of a system running but blowing warm or hot air is that it’s low on this essential ingredient. Refrigerant is not like gas, as it’s not something that your unit uses up as it works.

This means that if your system is low on refrigerant, it’s likely because you have a leak or another issue that needs to be addressed.

If your refrigerant line is icy or if you hear a bubbling or humming sound, that’s a good indication that you have a refrigerant leak.

This is an issue that needs to be handled by a trained technician, so if you suspect this is the problem, schedule a service appointment with a trusted HVAC technician as soon as possible.

The AC Unit Needs Cleaning

dirtyunitSometimes your system is simply not cooling because it’s dirty and not able to function properly. If either your outdoor or indoor unit is not properly maintained and cleaned, it can cause your system to stop cooling.

If the outdoor unit is blocked with dirt and debris, it’s not able to effectively release hot air. As you can imagine, this makes it less efficient at cooling your home. Additionally, if your air filters are dirty, they basically suffocate your system and significantly reduce the amount of cold air that makes it into your home.

Staying on top of routine cleaning is one of the AC services that you don’t want to forget. Having your unit cleaned at least once a year and regularly checking and replacing air filters can ensure that your system keeps your house cool even on the hottest days.

A New Unit was Improperly Installed

If you have a new unit that is not cooling, it might have been improperly installed. The installation process is complicated, and it’s essential that it’s done correctly for the system to work properly.

It’s important that you use a reputable contractor when installing a new AC system to avoid the headache of a new system not working. If you are in need of any AC services or need a unit installed, call us today at (502) 716-5430 to schedule an appointment.
