Why is My Air Conditioning System Not Dehumidifying?

Air conditioning is very important in the Montgomery County, MD area since it can get very humid, and homeowners throughout Gaithersburg, Germantown, Potomac, and Clarksburg are making sure their cooling systems are ready to go for the entire summer. As you start your unit back up after a long season of non-use, you may find that it is in need of professional AC repair. This is going to be more likely if you didn’t schedule timely AC tune-ups in the past.
At Michael Bonsby HVAC, Plumbing & Electrical, one common AC problem we often hear about from our customers is that their units are not dehumidifying properly. As you may know already, your air conditioner dehumidifies the air as part of its normal operation. Do you think your unit is not properly dehumidifying the air? It likely indicates that your air conditioning system has a serious operational problem.

Possible Causes of an AC System That is Not Dehumidifying

Here are some possible reasons an AC system may not be dehumidifying properly:

Inadequate Refrigerant Charge

When we talk about inadequate refrigerant charge, the “charge” refers to the level of refrigerant that circulates through your unit’s compressor pump, evaporator, and condenser. Your AC system must have the correct amount of refrigerant at all times. If you have low refrigerant charge, it’s possible that your AC system will not properly dehumidify the air.

Oversized System

If your AC system does not dehumidify the air and also frequently turns on and off, it is probably too large for your home. What happens is that the high-powered system cools the air at such a fast rate that the air does not spend enough time moving over the evaporator coil to be dehumidified. After your thermostat shuts off the cooling because your home has reached the desired temperature, there is still a lot of humidity in the air.

Dirt and Debris in the System

One of the best ways to prevent damage to your system is to ensure that all of its components are clean and clear of any dirt and debris. If your coils are covered in dust, you cannot expect it to work efficiently, and one of the possible outcomes is a lack of dehumidification.

If your AC system is not dehumidifying properly, it requires professional attention. Make sure your AC performs efficiently this cooling season by contacting Michael Bonsby HVAC, Plumbing & Electrical for repair services in the Montgomery County, MD area.
