Why Planned System Checks?

The #1 cause of system breakdowns is lack of regular system checks.

Regardless of age, brand or who installed your existing equipment, keeping it maintained saves you money. Equipment manufacturers require regular service checks + maintenance by a certified technician to validate and preserve their warranties. Warranties cover defects, not repairs required due to lack of maintenance. Good news, it’s never too late (or too soon) to start a proper system check plan.

Lower Utility Bills

Avoid overpaying utilities. System checks can help you lower your bills! When your heating and cooling system is in good shape, it won’t have to work as hard to keep your home comfortable.

Extend the Life 

No one wants to have to replace their heating and cooling system prematurely. Units that get regular system checks last much longer than units that do not.

Save Money

Prevent unnecessary repairs. With regular system checks, 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.

Year Round Comfort

The purpose of having AC in the first place is to help you stay comfortable year round. With preventative service checks, your unit will work efficiently and effectively.

It's never too late to start planned system checks.
