When it’s a searing summer afternoon in Libertyville, nothing is worse than registering your home comfort system isn’t performing the way it is supposed to. The last thing you want to do is request cooling system service. But your AC is a fairly complex system, so it can be hard to determine what’s triggering the problem solo.

That’s why TopTec created this guide to help you understand what might be happening with your AC. From here, you’ll discover some prevailing reasons your home is feeling too warm. And while a few of these are simple] DIY tasks, you may need to turn to a skilled technician for AC repair.

And if that’s the case, TopTec is ready to assist. Here are five reasons why your air conditioner may not be cooling your house in Libertyville.

1. Your Thermostat Settings May Be Incorrect

Everyone adjusts their thermostat a little differently to match their specific preferences. However, a number of families make the misstep of setting their device to “On” rather than “Auto.” Because of this setting, the fan in your AC will continue to produce an air current even after you’ve achieved your set temperature.

This can look like your vents are distributing warm air, when really it’s simply utilizing the fan more often than necessary. Change this setting and work out if things seem better.

2. Your System Needs a Good Cleaning

There are two primary areas to look for dirt or dust buildup when your air conditioner doesn’t appear to be performing as it should.

Before anything else, examine your HVAC filter. If you don’t change your filter often enough, accumulated dirt can make it hard for air to pass through and cool your home. If your filter is noticeably dirty or dusty, it’s likely time for a change. (And as a rule, you should replace it about once every three months at a minimum.)

If your filter is looking good, go to your outdoor unit. Find out if there’s adequate room around your air conditioner and clean up plants or litter close by. This section of your cooling system discharges the heat from your home. If the coils outside are blocked, you won’t be comfortable indoors.

We suggest setting professional air conditioner maintenance yearly to keep your unit operating properly and to keep your warranty valid.

3. Your Unit is Leaking Refrigerant

Refrigerant is the substance that cools the air in your house. It moves between your inside and outside system elements to grab and release heat, to help your space keep cool. If there is a crack along that path, you won’t be cool again until you book professional air conditioning repair.

Indications of a refrigerant leak include a drop in chilled air, pricier monthly charges, frozen evaporator coils and unusual hissing noises arising from your system.

If you suspect refrigerant could be leaking, call TopTec for system repair as soon as possible. Refrigerant can also be harmful to your family’s health.

4. One or More Pieces Need to Be Replaced

Your AC includes a a handful of important parts. These include the blower, evaporator coils, compressor, fan, condenser coils and expansion valve. If any one of these is not working as it should, your home comfort is hurt.

Our TopTec technicians are well-trained and skilled in all areas of HVAC. They can help you find and fix any problem.

5. Your AC Needs to Be Upgraded

If your equipment is more than 10 years old, it could likely be 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 could be making your space less comfortable.

If your AC is more current but still isn’t cooling things off, it may be too small for your house. AC units are not all the same size. An air conditioner that’s undersized just can’t help a space the way an appropriately sized air conditioner can.
