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

July 10, 2020

When it’s a searing summer morning in Lawrence, nothing could be worse than recognizing your HVAC isn’t functioning the way it should. The last thing you should have to do is call for AC help. But your air conditioner is an incredibly complex system, so it can be almost impossible to discern what’s triggering the trouble on your own.

That’s why Scott Temperature wrote this informational guide to help you see what may be happening with your air conditioner. Here, you’ll discover a few typical explanations for why your space is feeling too warm. And while some of these are simple DIY projects, you could have to turn to a professional for cooling system repair.

And if that’s the case, Scott Temperature is ready to assist. Here are five reasons why your air conditioner may not be cooling your house in Lawrence.

1. Your System Settings May Be Wrong

Every person uses their thermostat a little differently to work with their particular preferences. However, a lot of homeowners make the mistake of setting their system to “On” rather than “Auto.” With this setting, the fan in your system will continue to blow even when you’ve reached your set temperature.

This can appear like your system is blowing out room temperature air, when actually it’s simply using the fan more often than required. Adjust this setting and see if things change.

2. Your Cooling System Needs Some Cleaning

There are two central areas to look for dirt or dust accumulation when your air conditioner doesn’t appear to be operating as it should.

Firstly, take a look at your AC system’s filter. If you don’t switch your filter regularly, accumulated dirt can make it more difficult for air to pass through and cool down your house. If your filter is obviously dirty or dusty, it’s definitely time for a substitute. (And for best operation, you have to change it about once every three months or more frequently.)

If your filter seems fine, go to your outdoor unit. Find out if there’s a couple of feet of room around your air conditioner and sweep away plants or litter stuck there. This element of your home comfort system releases the heat from your rooms. If the coils outside are congested, you won’t be feeling cool inside.

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

3. Your Unit is Losing Refrigerant

Refrigerant is the chemical that cools down the air in your home. It moves between your internal and outdoor units to grab and release heat, to help your rooms get cool. If there is a crack along that system, you won’t be comfortable again until you schedule professional air conditioning repair.

Signals of a refrigerant leak include a lack of chilled air, pricier electric bills, frozen evaporator coils and strange hissing noises coming from your air conditioner.

If you suspect refrigerant may be leaking, call Scott Temperature for HVAC 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 AC includes a few crucial parts. These include the blower, evaporator coils, compressor, fan, condenser coils and expansion valve. If one part is not working, your home comfort crumbles.

Our Scott Temperature pros are trained and knowledged in HVAC. They can help you locate and mend any problem.

5. Your Whole System Has to Be Upgraded

If your air conditioner is more than 10 years old, it could be a good time to think about new air conditioner installation. As your system gets up there in years, it simply won’t operate as well as it did in the beginning. And it might be making your home less comfortable.

If your HVAC unit is more current but still isn’t cutting it, it may be undersized for your space. HVAC systems are made in different sizes. An air conditioner that’s too small absolutely can’t help a space the way an accurately sized AC can.
