When it’s a hot summer morning in Carpentersville, nothing could be worse than registering your air conditioner isn’t working the way it should. The last thing you need to do is call for cooling system repair. But your AC is a fairly complex system, so it can be difficult to determine what’s causing the issue on your own.

That’s why Controlled Comfort HVAC created this guide to help you understand what might be happening with your AC. From here, you’ll see some prevailing reasons your home is feeling a little unpleasant. And though a few of these are easy] DIY projects, you may need to call in a skilled technician for cooling system repair.

And if you do, Controlled Comfort HVAC is ready to assist. Here are five reasons why your air conditioner may not be cooling your house in Carpentersville.

1. Your Device Settings Are Incorrect

Everyone uses their thermostat a little differently to match their personal needs. However, a lot of families make the error of setting their system to “On” rather than “Auto.” Under this setting, the fan in your AC will continue to push out air even after you’ve attained your set temperature.

This can appear like your AC is pushing out warm air, when really it’s only employing the fan more frequently than needed. Try switching this setting and find out if things cool off.

2. Your System Needs Some Cleaning

There are two primary areas to look for dirt or dust buildup when your home comfort system doesn’t feel like it is performing as it should.

Before anything else, check out your system’s filter. If you don’t change your filter on a regular basis, built-up dust can make it more difficult for air to move through and lower the temperature your space. If your filter is visibly dirty or dusty, it’s probably time for a change. (And as a rule, you have to change it about once every three months at a minimum.)

If your filter appears good, go to your external unit. Find out if there’s adequate space around your air conditioner and clear any plants or litter stuck there. This piece of your AC releases the heat from your house. If the coils outside are congested, you won’t be comfortable indoors.

We recommend setting professional air conditioner maintenance each year to keep your system working properly and to keep your warranty valid.

3. Your AC is Losing Refrigerant

Refrigerant is the chemical that cools the air in your house. It moves between your inside and external system pieces to soak up and release heat, to help your space stay comfortable. If there is a crack along that system, you won’t be feeling cool again until you set professional air conditioning repair.

Indications of a refrigerant leak include a decline in chilled air, more expensive monthly expenses, frozen evaporator coils and odd hissing noises arising from your air conditioner.

If you think refrigerant may be leaking, call Controlled Comfort HVAC for air conditioner repair as soon as possible. Refrigerant can also be damaging to your family’s health.

4. One or More Parts Have to Be Replaced

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

Our Controlled Comfort HVAC experts are well-trained and skilled in all areas of HVAC. They can help you locate and fix any trouble.

5. Your Air Conditioner Needs to Be Upgraded

If your AC is older than 10 years old, it may be time to research new air conditioner installation. As your system gets up there in years, it sadly won’t run as well as it has in the past. And it may be making your house uncomfortable.

If your AC is newer but still isn’t cooling things off, it could be too small for your living space. AC units are not all the same size. A cooling system that’s not powerful enough simply can’t cool a home the way a correctly sized air conditioner can.
