When it’s a warm summer day in McKinney and Frisco, nothing feels worse than realizing your air conditioner isn’t operating the way it should. The last thing you need to do is call for AC repair. But your HVAC is a fairly intricate system, so it can be almost impossible to determine what’s causing the trouble solo.

That’s why Bell Mechanical Services made this handbook to help you understand what could be taking place with your cooling system. Below, you’ll discover a few prevailing situtations that explain why your house is feeling uncomfortable. And though a couple of these are straightforward] DIY projects, you may need to bring in a pro for cooling system repair.

And if that’s the case, Bell Mechanical Services is ready to assist. Here are five reasons why your air conditioner may not be cooling your house in McKinney and Frisco.

1. Your Thermostat Settings May Be Incorrect

Every family adjusts their thermostat a little differently to match their specific requirements. However, a lot of families make the misstep of setting their system to “On” rather than “Auto.” Under this setting, the fan in your AC will continue to blow even once you’ve achieved your preferred temperature.

This can look like your ducts are distributing warm air, when actually it’s only using the fan more often than necessary. Change this setting and see if things seem better.

2. Your HVAC Needs to Be Cleaned

There are two primary places to look for dirt or dust buildup when your cooling system doesn’t appear to be operating as it should.

Before anything else, take a look at your AC system’s filter. If you don’t change your filter on a regular basis, built-up dust can make it hard for air to move through and lower the temperature your space. If your filter is visibly dirty or dusty, it’s probably time for a change. (And in general, you should replace it about once every three months at least.)

If your filter seems good, go to your external unit. Double check there’s enough space around it and clear away plants or litter close by. This section of your cooling system releases the heat from your space. If the coils outside are congested, you won’t be feeling comfortable indoors.

We advise scheduling professional air conditioner maintenance every year to keep your unit running smoothly and to keep your warranty valid.

3. Your Unit is Losing Refrigerant

Refrigerant is the chemical that cools the air in your home. It moves between your internal and external units to absorb and release heat, to help your home stay the right temperature. If there is an opening along the way, you won’t be feeling comfortable again until you set professional air conditioning repair.

Indications of a refrigerant leak include a drop in cooled air, pricier electric bills, frozen evaporator coils and odd hissing noises originating from your air conditioner.

If you think refrigerant could be leaking, call Bell Mechanical Services for air conditioner repair as soon as possible. Refrigerant can also be damaging to your family’s health.

4. One or More Pieces Should Be Replaced

Your system is made up of a a handful of crucial parts. These include the blower, evaporator coils, compressor, fan, condenser coils and expansion valve. If one part is failing, your home comfort is hurt.

5. Your Whole System Should Be Updated

If your AC is over 10 years old, it may be time to think about new air conditioner installation. As your system gets up there in years, it sadly won’t run as well as it did in the beginning. And it might be making your house less comfortable.

If your AC is more current but still isn’t properly cooling your home, it might be undersized for your living space. AC units are not all the same size. A cooling system that’s not powerful enough just can’t chill a place the way an appropriately sized air conditioner can.
