If you’ve been without air conditioning on a hot day, you know how frustrating unexpected HVAC problems can be.

When not properly maintained, the equipment may be working harder than it should, wasting energy and shortening its life expectancy.

Preventive maintenance is more than changing filters. It includes checking all of the safety components built into each system. It is about efficiency testing to ensure controls are set properly, thus providing for peak performance. Proper preventive maintenance is designed to increase efficiency, extend equipment life and reduce the likelihood of a breakdown.
