Services

We repair all makes and models. As a factory-authorized Carrier dealer, Carrier is the equipment we recommend, and our technicians repair whatever you already own.

Our technicians are NATE-certified and trained continuously, because the diagnostic approach that suited a 2005 furnace does not carry over to a communicating, variable-speed system with a proprietary control bus.

We repair residential and commercial equipment: split systems, package units, rooftop units, heat pumps, ductless systems, gas furnaces, boilers, air handlers and commercial refrigeration.

When a repair no longer makes financial sense, we will tell you so and show you the comparison.

How it works

How a repair visit works

  1. You call the office

    Tell us what the system is doing, and we will let you know the diagnostic fee before we come out.

  2. We find the real fault

    A NATE-certified technician tests the system and pinpoints the cause before any parts are replaced.

  3. You decide

    We explain what the repair will cost, and the decision is yours. On an older unit, we show you the repair-versus-replace numbers as well.

  4. We fix it

    We carry common parts on our trucks, so many repairs are finished on the first visit.

If a system is not worth repairing, we will tell you so and show you the numbers.
