We will give you peace of mind knowing the experts have taken care of any potential hazards.

Steps to Maintaining Your Heating and Cooling System:

Changing the Filter:

One of the best ways to maintain proper airflow is by changing your filters about once per month. Some units have an indicator prompting you to change the filter.

Clean Units:

Hose off any dirt or debris from the outside of units. If any of the fins were bent, straighten them with a butter knife.

Keep Outdoor Units Clear:

Trim any grass, tree branches, or other foliage from around any outdoor units. We recommend having a boundary of 12-18 inches.

Open Vents:

Make sure to leave an open space in front of all intake and output vents inside your home. Even more substantial items such as furniture or drapes should be out of the way.
