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

July 10, 2020

When it’s a searing summer day in Pacheco, nothing is worse than figuring out your home comfort system isn’t working the way it was built to. The last thing you should have to do is schedule air conditioner help. But your HVAC is an exceptionally intricate system, so it can be difficult to discover what’s causing the problem all alone.

That’s why Clean Air HVAC created this informational guide to help you see what might be happening with your AC. Below, you’ll learn a few everyday explanations for why your house is feeling uncomfortable. And though a couple of these are fairly painless DIY activities, you might want to find an expert for air conditioner repair.

And if you do, Clean Air HVAC is prepared to take care of your home. Here are five reasons why your air conditioner may not be cooling your house in Pacheco.

1. Your Thermostat Settings Are Wrong

Every home sets their thermostat a bit differently to fit their distinct needs. Yet, a lot of families make the misstep of setting their thermostat to “On” rather than “Auto.” Because of this setting, the fan in your system will continue to push out air even when you’ve gotten to your preferred temperature.

This can seem like your ducts are pushing out warmish air, when really it’s only employing the fan more often than needed. Swap this setting and determine if things seem better.

2. Your AC Needs Some Cleaning

There are two central spaces to check for dirt or dust buildup when your home comfort system doesn’t feel like it is working as it should.

Firstly, take a look at your system’s filter. If you don’t swap out your filter often enough, buildup can make it more challenging for air to pass through and cool down your space. If your filter is noticeably dirty or dusty, it’s probably time to replace it. (And as a rule, you need to change it about once every three months at the very least.)

If your filter appears good, go to your outside unit. Make sure there’s a reasonable amount of room around your air conditioner and clear away plants or debris around it. This part of your system lets out the heat from inside your house. If the coils outside are blocked, you won’t be cool in your home.

We advise booking professional air conditioner maintenance each year to keep your unit operating smoothly and to keep your warranty valid.

3. Your Unit is Releasing Refrigerant

Refrigerant is the material that cools the air in your home. It runs between your internal and external system elements to soak up and release heat, to help your home get cool. If there is a crack along that system, you won’t be feeling comfortable again until you set professional air conditioning repair.

Signals of a refrigerant leak include a decline in treated air, higher energy bills, frozen evaporator coils and odd hissing noises originating from your HVAC.

If you think refrigerant could be leaking, call Clean Air HVAC for HVAC repair as soon as possible. Refrigerant can also be hazardous to your family’s health.

4. One or More Parts Need to Be Replaced

Your cooling system is made up of 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 declines.

Our Clean Air HVAC technicians are certified and knowledged in HVAC. They can help you locate and mend any issue.

5. Your Air Conditioner Has to Be Upgraded

If your AC is upward of 10 years old, it could be a good time to consider new air conditioner installation. As your system gets older, 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 newer but still isn’t keeping you cool, it could be undersized for your living space. AC units are not all the same. A cooling system that’s undersized simply can’t cool a space the way a correctly sized HVAC can.
