When it’s a searing summer afternoon in Frederick, nothing is worse than registering your AC isn’t working the way it is meant to. The last thing you should have to do is schedule cooling system help. But your HVAC is a quite complicated system, so it can be almost impossible to figure out what’s causing the trouble on your own.

That’s why May's Heating & Air made this handbook to help you figure out what could be taking place with your cooling system. Here, you’ll find a couple typical explanations for why your house is feeling a little unpleasant. And even though some of these are simple] DIY projects, you could need to bring in an expert for air conditioner repair.

And if that’s the case, May's Heating & Air is prepared to take care of your home. Here are five reasons why your air conditioner may not be cooling your residence in Frederick.

1. Your Thermostat Settings May Be Wrong

Every person adjusts their thermostat a bit differently to suit their distinct preferences. Even so, many people make the misstep of setting their system to “On” rather than “Auto.” Under this setting, the fan in your system will continue to blow even when you’ve reached your desired temperature.

This can feel like your AC is distributing warmish air, when really it’s simply using the fan more often than needed. Try switching this setting and see if things cool off.

2. Your Air Conditioner Needs a Good Cleaning

There are two primary places to check for dirt or dust accrual when your home comfort system doesn’t seem to be operating as it should.

Before anything else, examine your system’s filter. If you don’t switch your filter often enough, built-up dust can make it hard for air to move through and cool your home. If your filter is noticeably dirty or dusty, it’s probably time to replace it. (And for best operation, you need to switch it about once every three months at the very least.)

If your filter appears fine, head to your outside unit. Find out if there’s enough room around your air conditioner and clear away plants or litter close by. This part of your system discharges the heat from your house. If the coils outside are blocked, you won’t be comfortable in your home.

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

3. Your Unit is Leaking Refrigerant

Refrigerant is the substance that conditions the air in your space. It runs between your internal and outdoor system elements to soak up and let off heat, to help your house remain cool. If there is an opening along the way, you won’t be feeling comfortable again until you set professional air conditioning repair.

Signals of a refrigerant leak include a drop in cooled air, more expensive monthly expenses, frozen evaporator coils and unusual hissing noises arising from your AC.

If you are worried refrigerant could be leaking, call May's Heating & Air for AC repair as soon as possible. Refrigerant can also be harmful to your family’s health.

4. One or More Pieces Have to Be Replaced

Your AC contains a a handful of important pieces. These include the blower, evaporator coils, compressor, fan, condenser coils and expansion valve. If any one of these is broken, your home comfort will suffer.

Our May's Heating & Air experts are certified and knowledged in HVAC. They can help you diagnose and mend any problem.

5. Your Whole System Should Be Updated

If your system is more than 10 years old, it could likely be time to research new air conditioner installation. As your system gets older, it unfortunately won’t function as well as it once did. And it could be making your house too warm.

If your HVAC unit is newer but still isn’t properly cooling your home, it might be undersized for your house. HVAC systems are not all the same size. An AC that’s not powerful enough simply can’t chill a house the way an appropriately sized air conditioner can.
