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

July 10, 2020

When it’s a searing summer morning in Dresden, nothing feels worse than recognizing your HVAC isn’t performing the way it should. The last thing you want to do is schedule cooling system help. But your HVAC is a fairly complex system, so it can be hard to determine what’s causing the issue all alone.

That’s why McFadden Heating & Cooling created this informational guide to help you figure out what might be happening with your home comfort system. Here, you’ll discover a few typical situtations that explain why your place is feeling uncomfortable. And though a few of these are straightforward DIY activities, you could want to bring in an expert for cooling system repair.

And if you do, McFadden Heating & Cooling is ready to assist. Here are five reasons why your air conditioner may not be cooling your house in Dresden.

1. Your Device Settings Are Wrong

Every household sets their thermostat a little differently to work with their particular preferences. Still, a lot of homeowners make the misstep 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 after you’ve achieved your preferred temperature.

This can look like your vents are pushing out warmish air, when really it’s just using the fan more often than required. Try switching this setting and work out if things seem better.

2. Your Home Comfort System Needs Some Cleaning

There are two central areas to look for dirt or dust collection when your HVAC doesn’t appear to be operating right.

Firstly, check out your HVAC filter. If you don’t swap out your filter regularly, accumulated dirt can make it more difficult for air to pass through and cool down your home. If your filter is clearly dirty or dusty, it’s probably time for a change. (And for best operation, you have to replace it about once every three months at least.)

If your filter is looking clean, move to your external unit. Double check there’s enough clearing around your air conditioner and clean up plants or debris around it. This part of your system lets out the heat from inside your space. If the coils outside are closed off, you won’t be feeling cool in your home.

We suggest scheduling professional air conditioner maintenance each year to keep your system working like it should and to keep your warranty valid.

3. Your System is Releasing Refrigerant

Refrigerant is the substance that conditions the air in your house. It cycles between your inside and outdoor system pieces to soak up and let off heat, to help your rooms get cool. If there is a break along that system, you won’t be feeling comfortable again until you set professional air conditioning repair.

Indications of a refrigerant leak include a lack of conditioned air, more expensive energy bills, frozen evaporator coils and odd hissing noises arising from your air conditioner.

If you suspect refrigerant may be leaking, call McFadden Heating & Cooling for system repair as soon as possible. Refrigerant can also be damaging to your family’s health.

4. One or More Pieces Need to Be Replaced

Your AC is made up of a couple key pieces. These include the blower, evaporator coils, compressor, fan, condenser coils and expansion valve. If any part is broken, your home comfort will suffer.

Our McFadden Heating & Cooling experts are certified and knowledged in HVAC. They can help you diagnose and fix any problem.

5. Your Whole System Needs to Be Replaced

If your air conditioner is upward of 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 work as well as it once did. And it may be making your space less comfortable.

If your HVAC unit is newer but still isn’t properly cooling your home, it could be too small for your living space. HVAC systems are not all the same. A system that’s undersized simply can’t chill a home the way an appropriately sized HVAC can.
