When it’s a hot summer afternoon in Greensburg, nothing could be worse than realizing your AC isn’t operating the way it was built to. The last thing you need to do is call for air conditioner service. But your AC is a quite intricate system, so it can be hard to determine what’s causing the problem on your own.

That’s why Wallpe Heating & Cooling wrote this informational guide to help you understand what might be going on with your home comfort system. Here, you’ll see some common explanations for why your space is feeling a little unpleasant. And even though a few of these are simple] DIY projects, you could need to turn to a pro for air conditioner repair.

And if you do, Wallpe Heating & Cooling is ready to assist. Here are five reasons why your air conditioner may not be cooling your house in Greensburg.

1. Your Device Settings May Be Incorrect

Every person sets their thermostat a bit differently to match their specific needs. However, a number of people make the misstep of setting their system to “On” rather than “Auto.” Under this setting, the fan in your AC will continue to blow even when you’ve reached your set temperature.

This can seem like your vents are distributing warmish air, when really it’s just employing the fan more frequently than required. Trying changing this setting and see if things cool off.

2. Your System Needs a Good Cleaning

There are two central places to look for dirt or dust accrual when your home comfort system doesn’t appear to be operating as it should.

Before anything else, check out your HVAC filter. If you don’t swap out your filter routinely, accumulated dirt can make it hard for air to pass through and cool your house. If your filter is obviously dirty or dusty, it’s definitely time for a change. (And as a rule, you have to switch it about once every three months at the very least.)

If your filter is looking fine, head to your external unit. Make sure there’s a reasonable amount of clearing around your air conditioner and clear any plants or litter close by. This part of your AC discharges the heat from your home. If the coils outside are congested, you won’t be feeling cool inside.

We recommend scheduling professional air conditioner maintenance yearly to keep your equipment working like it should and to keep your warranty valid.

3. Your System is Releasing Refrigerant

Refrigerant is the chemical that cools the air in your house. It moves between your indoor and external system pieces to grab and let off heat, to help your space remain cool. If there is a leak along the way, you won’t be feeling comfortable again until you book professional air conditioning repair.

Signals of a refrigerant leak include a decline in cooled air, pricier utility bills, frozen evaporator coils and unusual hissing noises originating from your AC.

If you are worried refrigerant may be leaking, call Wallpe Heating & Cooling for AC repair as soon as possible. Refrigerant can also be hazardous to your family’s health.

4. One or More Pieces Should Be Replaced

Your air conditioner is made up of a couple important elements. These include the blower, evaporator coils, compressor, fan, condenser coils and expansion valve. If any one of these is failing, your home comfort suffers.

Our Wallpe Heating & Cooling pros are certified and experienced in HVAC. They can help you diagnose and fix any problem.

5. Your Whole System Needs to Be Updated

If your system is over 10 years old, it is probably a good time to research new air conditioner installation. As your system gets older, it sadly won’t work as well as it did in the beginning. And it might be making your space too warm.

If your system is newer but still isn’t properly cooling your home, it may be too small for your house. Air conditioners are not all the same. A cooling system that’s too small simply can’t chill a space the way a properly sized HVAC can.
