When it’s a warm summer day in Florissant and St. Charles, nothing is worse than realizing your air conditioner isn’t working the way it was built to. The last thing you should have to do is request cooling system service. But your air conditioner is a pretty complex system, so it can be almost impossible to determine what’s causing the problem without training.

That’s why B & B Heating & Cooling wrote this informational guide to help you figure out what might be going on with your home comfort system. Here, you’ll learn some common situtations that explain why your space is feeling a little too warm. And while a couple of these are simple] DIY activities, you could need to bring in a pro for cooling system 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 residence in Florissant and St. Charles.

1. Your Device Settings Are Off

Everyone uses their thermostat a little differently to suit their individual preferences. Yet, many families make the mistake of setting their thermostat to “On” instead of “Auto.” With this setting, the fan in your AC will continue to produce an air current even when you’ve attained your set temperature.

This can seem like your ducts are pushing out warmish air, when in reality it’s just utilizing the fan on a more regular basis than needed. Try switching this setting and work out if things seem better.

2. Your HVAC Needs Some Cleaning

There are two primary places to look for dirt or dust accrual when your AC doesn’t feel like it is operating well.

Before anything else, check out your system’s filter. If you don’t swap out your filter routinely, buildup can make it more difficult for air to move through and cool your space. If your filter is visibly dirty or dusty, it’s definitely time to replace it. (And for best operation, you should change it about once every three months at the very least.)

If your filter appears fine, head to your external unit. Make sure there’s adequate space around the unit and clear away plants or dirt stuck there. This section of your cooling system discharges the heat from within your space. If the coils outside are clogged, you won’t be feeling comfortable in your home.

We advise booking professional air conditioner maintenance every year to keep your system running like it should and to keep your warranty valid.

3. Your Unit is Releasing Refrigerant

Refrigerant is the material that conditions the air in your space. It moves between your indoor and outside system elements to absorb and discharge heat, to help your house remain comfortable. If there is a leak along that path, you won’t be comfortable again until you book professional air conditioning repair.

Signals of a refrigerant leak include a decline in cooled air, higher utility bills, frozen evaporator coils and unusual hissing noises arising from your HVAC.

If you think refrigerant may be leaking, call B & B Heating & Cooling for air conditioner repair as soon as possible. Refrigerant can also be hazardous to your family’s health.

4. One or More Parts Have to Be Replaced

Your system is made up of a couple essential pieces. These include the blower, evaporator coils, compressor, fan, condenser coils and expansion valve. If any one of these is not working as it should, your home comfort will suffer.

Our B & B Heating & Cooling experts are well-trained and knowledged in HVAC. They can help you find and fix any issue.

5. Your Whole System Has to Be Upgraded

If your AC is more than 10 years old, it may be about time to research 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 home less comfortable.

If your AC is on the younger side but still isn’t cutting it, it might be the wrong size for your home. Air conditioners are not all the same. An AC that’s not big enough just can’t help a house the way a correctly sized air conditioner can.
