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

July 10, 2020

When it’s a warm summer day in Kearney, nothing could be worse than registering your HVAC isn’t working the way it is supposed to. The last thing you need to do is call for AC help. But your HVAC is a pretty complicated system, so it can be challenging to figure out what’s driving the issue without training.

That’s why Thurston Heating & Air Conditioning wrote this guide to help you see what could be happening with your AC. Below, you’ll discover some common situtations that explain why your family is feeling a little too warm. And though some of these are straightforward DIY activities, you could still need to find a professional for AC repair.

And if need help, Thurston Heating & Air Conditioning is ready to assist. Here are five reasons why your air conditioner may not be cooling your home in Kearney.

1. Your System Settings Are Incorrect

Every home sets their thermostat a little differently to suit their specific requirements. Nevertheless, a lot of people make the error of setting their thermostat to “On” instead of “Auto.” Under this setting, the fan in your HVAC system will continue to push out air even when you’ve attained your set temperature.

This can come off like your ducts are blowing out warmish air, when really it’s only using the fan more often than required. Adjust this setting and determine if things cool off.

2. Your HVAC Needs Some Cleaning

There are two main places to inspect for dirt or dust buildup when your AC doesn’t appear to be operating right.

Firstly, take a look at your HVAC filter. If you don’t swap out your filter often enough, built-up dust can make it more labor intensive for air to move through and cool your home. If your filter is noticeably dirty or dusty, it’s likely time for a substitute. (And for best operation, you need to switch it about once every three months at a minimum.)

If your filter seems clean, move to your outdoor unit. See if there’s a couple of feet of clearing around it and clear any plants or dirt around it. This part of your system discharges the heat from your rooms. If the coils outside are clogged, you won’t be comfortable in your home.

We recommend setting professional air conditioner maintenance yearly to keep your system running like it should and to keep your warranty valid.

3. Your System is Losing Refrigerant

Refrigerant is the chemical that cools down the air in your space. It moves between your internal and outdoor system elements to grab and release heat, to help your house remain cool. If there is a break along that path, you won’t be comfortable again until you set professional air conditioning repair.

Signals of a refrigerant leak include a drop in cooled air, more expensive energy expenses, frozen evaporator coils and unusual hissing noises arising from your air conditioner.

If you feel refrigerant could be leaking, call Thurston Heating & Air Conditioning for AC repair as soon as possible. Refrigerant can also be damaging to your family’s health.

4. One or More Parts Should Be Replaced

Your AC contains a few essential parts. These include the blower, evaporator coils, compressor, fan, condenser coils and expansion valve. If one of these is not working, your home comfort crumbles.

Our Thurston Heating & Air Conditioning pros are certified and experienced in HVAC. They can help you figure out and repair any problem.

5. Your Air Conditioner Should Be Updated

If your system is more than 10 years old, it is probably about time to consider new air conditioner installation. As your system gets up there in years, it just won’t function as well as it did when it was new. And it could be making your house too warm.

If your system is more current but still isn’t properly cooling your home, it could be undersized for your house. AC units are not all the same size. An air conditioner that’s undersized simply can’t help a space the way a properly sized air conditioner can.
