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

July 10, 2020

When it’s a hot summer day in Lincoln, nothing feels worse than figuring out your home comfort system isn’t operating the way it was built to. The last thing you should have to do is call for air conditioner help. But your air conditioner is an exceptionally involved system, so it can be challenging to deduce what’s causing the trouble by yourself.

That’s why AW Heating & Air Conditioning wrote this handbook to help you figure out what could be going on with your cooling system. Here, you’ll discover a few everyday reasons your space is feeling uncomfortable. And though some of these are straightforward DIY activities, you could have to find an expert for HVAC repair.

And if that’s the case, AW Heating & Air Conditioning is ready to assist. Here are five reasons why your air conditioner may not be cooling your house in Lincoln.

1. Your Thermostat Settings May Be Off

Every household sets their thermostat a touch differently to fit their specific preferences. Yet, many households make the mistake of setting their device to “On” rather than “Auto.” With this setting, the fan in your AC will continue to produce an air current even after you’ve achieved your preferred temperature.

This can appear like your ducts are distributing warm air, when in reality it’s just using the fan more often than required. Swap this setting and determine if things seem better.

2. Your HVAC Needs a Routine Cleaning

There are two central spaces to look for dirt or dust accumulation when your home comfort system doesn’t feel like it is operating correctly.

First off, check out your system’s filter. If you don’t replace your filter often enough, built-up dust can make it more difficult for air to pass through and cool down your home. If your filter is obviously dirty or dusty, it’s definitely time for a change. (And in general, you need to switch it about once every three months at the very least.)

If your filter is looking clean, head to your outside unit. See if there’s a reasonable amount of clearing around your air conditioner and clear away plants or dirt close by. This section of your cooling system lets out the heat from inside your home. If the coils outside are congested, you won’t be cool indoors.

We advise booking professional air conditioner maintenance annually to keep your unit operating like it should and to keep your warranty valid.

3. Your System is Leaking Refrigerant

Refrigerant is the substance that cools down the air in your house. It moves between your inside and outdoor system pieces to grab and release heat, to help your house keep cool. If there is a crack along the way, you won’t be feeling comfortable again until you schedule professional air conditioning repair.

Signs of a refrigerant leak include a lack of conditioned air, pricier electric expenses, frozen evaporator coils and strange hissing noises coming from your system.

If you are worried refrigerant might be leaking, call AW Heating & Air Conditioning for system repair as soon as possible. Refrigerant can also be detrimental to your family’s health.

4. One or More Elements Need to Be Replaced

Your air conditioner is made up of a a handful of essential pieces. 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 AW Heating & Air Conditioning pros are well-trained and skilled in all areas of HVAC. They can help you find and repair any problem.

5. Your Air Conditioner Needs to Be Upgraded

If your air conditioner is older than 10 years old, it may be a good time to look into new air conditioner installation. As your system ages, it sadly won’t work as well as it has in the past. And it may be making your house feel unpleasant.

If your AC is newer but still isn’t properly cooling your home, it might be too small for your household. AC units are not one-size-fits-all. An AC that’s too small absolutely can’t cool a place the way an appropriately sized air conditioner can.
