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

July 10, 2020

When it’s a searing summer morning in McMurray, nothing is worse than registering your air conditioner isn’t performing the way it was built to. The last thing you need to do is request HVAC help. But your air conditioner is an incredibly complex system, so it can be almost impossible to determine what’s driving the issue solo.

That’s why Kowalski Heating, Cooling & Plumbing wrote this informational guide to help you understand what could be taking place with your air conditioner. From here, you’ll uncover a couple usual reasons your family is feeling too warm. And even though some of these are fairly painless DIY activities, you may want to turn to a professional for HVAC repair.

And if you need us, Kowalski Heating, Cooling & Plumbing is here for you. Here are five reasons why your air conditioner may not be cooling your residence in McMurray.

1. Your Device Settings May Be Incorrect

Every person sets their thermostat a bit differently to match their specific needs. Despite that, a lot of households make the misstep of setting their device to “On” instead of “Auto.” Under this setting, the fan in your system will continue to push out air even when you’ve reached your preferred temperature.

This can seem like your ducts are pushing out warm air, when in reality it’s simply using the fan on a more regular basis than needed. Switch this setting and see if things seem better.

2. Your HVAC Needs to Be Cleaned

There are two principal spaces to examine for dirt or dust buildup when your air conditioner doesn’t appear to be performing as it should.

Before anything else, inspect your AC system’s filter. If you don’t switch your filter regularly, built-up dust can make it more challenging for air to flow through and cool down your space. If your filter is visibly dirty or dusty, it’s likely time for a change. (And in general, you should change it about once every three months or more frequently.)

If your filter seems clean, go to your external unit. Double check there’s a reasonable amount of space around your air conditioner and clear any plants or dirt close by. This element of your cooling system releases the heat from your rooms. If the coils outside are clogged, you won’t be feeling cool inside.

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

3. Your Unit is Leaking Refrigerant

Refrigerant is the stuff that chills the air in your house. It moves between your inside and outside system elements to grab and discharge heat, to help your space remain the right temperature. If there is a leak along that system, you won’t be cool again until you set professional air conditioning repair.

Indicators of a refrigerant leak include a decrease in treated air, higher monthly expenses, frozen evaporator coils and odd hissing noises coming from your air conditioner.

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

4. One or More Elements Have to Be Replaced

Your cooling system includes a few important pieces. These include the blower, evaporator coils, compressor, fan, condenser coils and expansion valve. If any one of these is broken, your home comfort will suffer.

Our Kowalski Heating, Cooling & Plumbing pros are trained and experienced in HVAC. They can help you locate and repair any issue.

5. Your Whole System Should Be Updated

If your air conditioner is older than 10 years old, it is probably a good time to research new air conditioner installation. As your system gets up there in years, it unfortunately won’t operate as well as it did in the beginning. And it may be making your home less comfortable.

If your air conditioner is more current but still isn’t properly cooling your home, it may be the wrong size for your household. Air conditioners are not all the same. A system that’s too small absolutely can’t cool a space the way an appropriately sized air conditioner can.
