I had a heater repaired by Andrew who did a great job with diagnosing the problem and testing to verify the solution he determined would work. I have an old electric system that will be hard to replace. Andrew provided me with options and details that would help me make a decision in the future. Thanks for great service Fuse.

The Daikin heat pump and air handler system itself and the installation was excellent. The project planning and project management was sloppy, stressful, irresponsible, poorly managed and full of miscommunication. But, still, the Daikin heat pump and air handler system itself and the installation was excellent.

Fuse Service replaced my aged HVAC.

Easy from start to finish. Easy booking an appointment on line in the time slot I wanted. Tech showed up right on time, diagnosed and gave a quote within 15 minutes, and finished all the work within the time slot allotted. AC back up and running. Before he left he checked the system and gave me some suggestions.…

EV car charging station was installed by Vitaly. He is super knowledgeable, polite and did a thorough job in completing the work. He also explained the why’s during the process. He also did some switch repairs very quick and clean. Clearly one of the best Electrical vendors out there imho.
