My A/C system did not work and the diagnosis indicated that the thermometer broke. However, during the installation of the new thermometer, the technician checked out that the original cause was the wiring and so additional part was required. With the new part, the technician completed the re-installation of the new thermometer and he carefully checked to make sure that both the A/C and furnace are working before the completion of the service.
The technician was very patient and skillful.

The technician Harry was very helpful and efficient in performing the work. He explained to me in details what he believed was causing the problem with our water heater and recommended the proper setting of the controller to optimize the heater.
