Why Maintain?

The #1 cause of system breakdowns is lack of maintenance of heating and cooling systems.

Regardless of age, brand or who installed your existing equipment, keeping it maintained saves you money. Equipment manufacturers require planned maintenance to validate and preserve their warranties. Good news, it’s never too late (or too soon) to start a proper maintenance plan.

Lower Energy Bills

Maintenance can help you lower your bills! When your AC is in good shape, it won't have to work as hard to keep your home cool and comfortable.

Extend the Life 

No one wants to have to replace their cooling system prematurely. AC units that

get regular maintenance 

last much longer than units

that do not.

Save Money

With regular AC maintenance, you can avoid the need for costly repairs in the future. It is much more cost-effective to prevent problems than to deal with them after the fact.

Stay Comfortable

The purpose of having AC in the first place is to help you stay cool and comfortable. With preventative maintenance, your unit will work effectively.
