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

July 10, 2020

When it’s a warm summer morning in Tucson, nothing feels worse than realizing your home comfort system isn’t working the way it should. The last thing you want to do is request AC repair. But your HVAC is a pretty complicated system, so it can be challenging to figure out what’s triggering the issue by yourself.

That’s why A&M Heating & Cooling LLC wrote this handbook to help you find out what might be happening with your AC. Below, you’ll uncover a few common explanations for why your home is feeling a little too warm. And though a few of these are easy DIY activities, you might want to turn to an expert for cooling system repair.

And if that’s the case, A&M Heating & Cooling LLC is here for you. Here are five reasons why your air conditioner may not be cooling your house in Tucson.

1. Your Thermostat Settings Are Incorrect

Every person sets their thermostat a bit differently to suit their individual preferences. Nevertheless, a number of homeowners make the mistake of setting their thermostat to “On” instead of “Auto.” With this setting, the fan in your system will continue to push out air even when you’ve achieved your desired temperature.

This can come off like your ducts are blowing out warmish air, when really it’s just utilizing the fan more frequently than required. Try switching this setting and find out if things change.

2. Your Air Conditioner Needs a Good Cleaning

There are two primary spaces to examine for dirt or dust accrual when your HVAC doesn’t seem to be performing correctly.

First, examine your system’s filter. If you don’t swap out your filter routinely, built-up dust can make it more challenging for air to pass through and lower the temperature your home. If your filter is visibly dirty or dusty, it’s likely time for a change. (And in general, you need to switch it about once every three months at least.)

If your filter is looking good, move to your outside unit. Make sure there’s a reasonable amount of clearing around the unit and sweep away plants or litter around it. This element of your cooling system lets off the heat from inside your space. If the coils outside are congested, you won’t be feeling comfortable inside.

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

3. Your System is Losing Refrigerant

Refrigerant is the stuff that conditions the air in your house. It goes between your inside and outside units to absorb and let off heat, to help your house remain comfortable. If there is a crack along that system, you won’t be feeling cool again until you set professional air conditioning repair.

Indicators of a refrigerant leak include a lack of chilled air, climbing power bills, frozen evaporator coils and unusual hissing noises originating from your air conditioner.

If you feel refrigerant may be leaking, call A&M Heating & Cooling LLC for system repair as soon as possible. Refrigerant can also be damaging to your family’s health.

4. One or More Parts Need to Be Replaced

Your air conditioner is made up of a couple 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 suffers.

Our A&M Heating & Cooling LLC pros are certified and knowledged in HVAC. They can help you locate and mend any trouble.

5. Your AC Has to Be Replaced

If your equipment is over 10 years old, it could be time to research new air conditioner installation. As your system ages, it unfortunately won’t run as well as it once did. And it might be making your place feel unpleasant.

If your AC is newer but still isn’t cooling things off, it might be too small for your house. Air conditioners are made in different sizes. A cooling system that’s not powerful enough absolutely can’t cool a house the way an appropriately sized air conditioner can.
