Why Your A/C May Be Constantly Running

Summers in Arkansas can be pretty brutal for humans, as well as the systems that we rely on to keep us cool from the worst of the heat. One of the calls we receive frequently in the summer is for air conditioning systems that won’t stop running, causing spikes in energy use and expensive energy bills. Here are a few reasons an A/C unit could be constantly running and how to avoid them.

Improper Size

Whether it is the exterior unit or the ductwork, size is really important to the efficiency of your air conditioning system. If the unit is too small, it will have to work harder to achieve the desired temperature of your home, and may never be able to reach it. This will cause unnecessary wear and tear, and lead to an eventual breakdown.

If the unit is too large, the system will have shorter run times and will use more energy than necessary to cool the home. Shorter cycles will also stop the A/C from doing its other job which is to remove the moisture from the air, which will eventually cause mold to form in your home.

With ductwork, the sizing should be relative to the unit or it may not be able to handle or distribute the airflow effectively. For more information on duct size and other ductwork maintenance, see our previous blog, How to Help Your Ductwork Do Its Job.

Dirty A/C Coils

Condenser coils are exposed to dirt such as grass clippings, pet hair, and mud because they are a part of your outdoor unit. Cleaning them is critical to avoid restricted air flow through the unit.

Evaporator coils are harder to get to but should be cleaned often as well. The evaporator coil is constantly exposed to airflow, and airborne particles such as dust and dirt can build up easily. This causes the reduced efficiency of heat transfers from the air to the refrigerant, and in turn, causes poor cooling and higher energy costs. Middleton technicians make sure to check the efficiency of your unit’s coils during regular maintenance calls.

Old Age

Air conditioners, just like any other appliance in your home, need regular maintenance to continue to effectively do their jobs. Scheduling regular preventative maintenance can help to avoid all the above-mentioned issues. However, even with regular maintenance the unit will still age and will eventually require replacement. If you’re not sure how to tell when your system may need to be replaced, visit our blog HVAC 101: Age and Preservation. In addition, modern units are more energy efficient and in some cases more quiet, giving you and your family a cool and comfortable environment to escape the summer heat with lower energy use.
