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

July 10, 2020

When it’s a searing summer day in Jefferson City, nothing could be worse than realizing your air conditioner isn’t working the way it should. The last thing you should have to do is schedule AC repair. But your AC is an exceptionally complicated system, so it can be difficult to find out what’s creating the trouble by yourself.

That’s why Stieferman Heating Company Inc created this informational guide to help you understand what might be happening with your home comfort system. Here, you’ll find some common reasons your house is feeling too warm. And though a couple of these are fairly painless DIY tasks, you may still need to call in an expert for home comfort system repair.

And if you need us, Stieferman Heating Company Inc is ready to assist. Here are five reasons why your air conditioner may not be cooling your home in Jefferson City.

1. Your Device Settings May Be Wrong

Every household uses their thermostat a little differently to suit their individual needs. However, a number of households make the error of setting their thermostat to “On” rather than “Auto.” Under this setting, the fan in your HVAC system will continue to blow even after you’ve gotten to your preferred temperature.

This can appear like your vents are blowing out warmish air, when actually it’s simply using the fan more often than needed. Try switching this setting and determine if things cool off.

2. Your Cooling System Needs Some Cleaning

There are two main places to look for dirt or dust buildup when your cooling system doesn’t feel like it is working right.

First off, examine your AC system’s filter. If you don’t switch out your filter routinely, accumulated dirt can make it hard for air to move through and cool your home. If your filter is clearly dirty or dusty, it’s more than likely time for a substitute. (And in general, you should change it about once every three months at least.)

If your filter is looking fine, go to your outside unit. Double check there’s a reasonable amount of clearing around it and sweep away plants or dirt around it. This element of your AC lets off the heat from within your home. If the coils outside are blocked, you won’t be cool inside.

We advise scheduling professional air conditioner maintenance every year to keep your system operating like it should and to keep your warranty valid.

3. Your System is Leaking Refrigerant

Refrigerant is the substance that chills the air in your space. It runs between your internal and outdoor system pieces to absorb and release heat, to help your space stay the right temperature. If there is a leak somewhere, you won’t be feeling cool again until you book professional air conditioning repair.

Indicators of a refrigerant leak include a decrease in conditioned air, pricier electric expenses, frozen evaporator coils and unusual hissing noises originating from your AC.

If you think refrigerant might be leaking, call Stieferman Heating Company Inc for air conditioner repair as soon as possible. Refrigerant can also be detrimental to your family’s health.

4. One or More Elements Should Be Replaced

Your cooling system includes a a handful of key elements. These include the blower, evaporator coils, compressor, fan, condenser coils and expansion valve. If one part is not working, your home comfort suffers.

Our Stieferman Heating Company Inc technicians are certified and experienced in HVAC. They can help you locate and repair any issue.

5. Your Whole System Needs to Be Upgraded

If your air conditioner is older than 10 years old, it could be about time to consider new air conditioner installation. As your system gets older, it unfortunately won’t run as well as it did when it was new. And it could be making your home too warm.

If your AC is newer but still isn’t properly cooling your home, it could be too small for your living space. Air conditioners are made in different sizes. An AC that’s not powerful enough simply can’t chill a place the way an accurately sized air conditioner can.
