When it’s a warm summer day in Florissant and St. Charles, nothing feels worse than registering your AC isn’t performing the way it is supposed to. The last thing you need to do is schedule AC repair. But your air conditioner is a quite complex system, so it can be difficult to figure out what’s causing the issue solo.

That’s why B & B Heating & Cooling wrote this handbook to help you figure out what could be going on with your AC. From here, you’ll learn some common situtations that explain why your home is feeling a little unpleasant. And though some of these are easy] DIY tasks, you may need to bring in a skilled technician for HVAC repair.

And if that’s the case, B & B Heating & Cooling is here for you. Here are five reasons why your air conditioner may not be cooling your home in Florissant and St. Charles.

1. Your System Settings May Be Off

Every person adjusts their thermostat a touch differently to suit their specific needs. Yet, a number of homeowners make the mistake of setting their device to “On” instead of “Auto.” With this setting, the fan in your air conditioner will continue to push out air even when you’ve achieved your set temperature.

This can seem like your ducts are distributing untreated air, when really it’s simply employing the fan more often than needed. Change this setting and see if things change.

2. Your HVAC Needs Some Cleaning

There are two main places to check for dirt or dust buildup when your AC doesn’t appear to be performing correctly.

Firstly, take a look at your HVAC filter. If you don’t change your filter often enough, accumulated dirt can make it hard for air to move through and lower the temperature your space. If your filter is obviously dirty or dusty, it’s probably time to replace it. (And in general, you need to change it about once every three months at least.)

If your filter appears fine, move to your external unit. Find out if there’s adequate clearing around it and clear any plants or litter stuck there. This piece of your cooling system lets off the heat from your home. If the coils outside are clogged, you won’t be feeling cool inside.

We advise scheduling professional air conditioner maintenance yearly to keep your system running like it should and to keep your warranty valid.

3. Your AC is Losing Refrigerant

Refrigerant is the substance that chills the air in your home. It cycles between your indoor and external units to grab and release heat, to help your house stay cool. If there is a crack along that system, you won’t be cool again until you set professional air conditioning repair.

Indications of a refrigerant leak include a decrease in cooled air, more expensive monthly charges, frozen evaporator coils and unusual hissing noises coming from your system.

If you think refrigerant may be leaking, call B & B Heating & Cooling for air conditioner 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 air conditioner includes a few crucial parts. These include the blower, evaporator coils, compressor, fan, condenser coils and expansion valve. If one part is not working as it should, your home comfort is hurt.

Our B & B Heating & Cooling experts are trained and skilled in all areas of HVAC. They can help you diagnose and repair any issue.

5. Your System Has to Be Replaced

If your equipment is more than 10 years old, it could likely be about time to look into new air conditioner installation. As your system gets older, it simply won’t function as well as it did in the beginning. And it might be making your home uncomfortable.

If your HVAC unit is on the younger side but still isn’t cooling things off, it might be the wrong size for your home. HVAC systems are not one-size-fits-all. An AC that’s not big enough absolutely can’t cool a house the way an appropriately sized HVAC can.
