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

July 10, 2020

When it’s a warm summer morning in Monroe, nothing is worse than figuring out your home comfort system isn’t working the way it should. The last thing you want to do is call for AC repair. But your AC is a pretty complicated system, so it can be difficult to discern what’s causing the issue on your own.

That’s why Lanz Furnace and Fireplace created this guide to help you find out what might be happening with your home comfort system. Below, you’ll find a few everyday explanations for why your home is feeling too warm. And even though a couple of these are fairly painless DIY activities, you might still need to bring in a skilled technician for HVAC repair.

And if that’s the case, Lanz Furnace and Fireplace is prepared to take care of your home. Here are five reasons why your air conditioner may not be cooling your house in Monroe.

1. Your Thermostat Settings May Be Incorrect

Every home adjusts their thermostat a little differently to fit their particular preferences. However, a lot of homeowners make the error of setting their thermostat to “On” rather than “Auto.” Because of this setting, the fan in your HVAC system will continue to produce an air current even when you’ve gotten to your preferred temperature.

This can feel like your vents are distributing untreated air, when actually it’s only utilizing the fan more frequently than required. Trying changing this setting and see if things cool off.

2. Your Home Comfort System Needs Some Cleaning

There are two principal areas to check for dirt or dust accumulation when your AC doesn’t seem to be working as it should.

First, examine your system’s filter. If you don’t switch your filter regularly, built-up dust can make it hard for air to travel through and cool down your rooms. If your filter is noticeably dirty or dusty, it’s definitely time for a change. (And for best operation, you need to change it about once every three months or more frequently.)

If your filter appears fine, go to your outdoor unit. Make sure there’s a reasonable amount of space around the unit and clear any plants or debris stuck there. This section of your AC lets out the heat from your house. If the coils outside are clogged, you won’t be cool inside.

We recommend scheduling professional air conditioner maintenance yearly to keep your unit running smoothly and to keep your warranty valid.

3. Your AC is Losing Refrigerant

Refrigerant is the stuff that cools down the air in your house. It moves between your inside and outdoor units to grab and let off heat, to help your place keep the right temperature. If there is a leak somewhere, you won’t be cool again until you set professional air conditioning repair.

Signs of a refrigerant leak include a decrease in treated air, more expensive utility expenses, frozen evaporator coils and odd hissing noises arising from your HVAC.

If you are worried refrigerant might be leaking, call Lanz Furnace and Fireplace for air conditioner repair as soon as possible. Refrigerant can also be hazardous to your family’s health.

4. One or More Elements Have to Be Replaced

Your system is made up of a a handful of essential pieces. These include the blower, evaporator coils, compressor, fan, condenser coils and expansion valve. If one of these is broken, your home comfort is hurt.

Our Lanz Furnace and Fireplace technicians are certified and skilled in all areas of HVAC. They can help you figure out and fix any problem.

5. Your System Should Be Replaced

If your system is older than 10 years old, it is probably time to consider new air conditioner installation. As your system ages, it sadly won’t function as well as it once did. And it could be making your place uncomfortable.

If your air conditioner is newer but still isn’t properly cooling your home, it could be the wrong size for your living space. AC units are not all the same. A system that’s too small just can’t chill a house the way an accurately sized air conditioner can.
