The service man was on time. He really took his time to go over everything with my furnace. He then went over everything that he did before he left. Would highly recommend them.
Danielle is excellent technician.
Office didn't call to tell us original technician was not able to make previous 2 appointments is only reason for 4 stars not 5.

Thermall crew are friendly and efficient, and their products are built to last!
Great service

Our heat went out in the evening in 20-degree weather. ThermAll offered after-hours service and sent a technician from 45 minutes away at 9:00 Saturday night. Problem solved! Great service. Thanks.

Our service technician Jose was great. He is very knowledgeable and a good communicator.

Exceptional company, exhibiting an ideal work ethic that is lacking in most service entities. Danielle was very professional and courteous. She listened carefully to my description of the problem and immediately began addressing it. She was patient and focused. Another incredible ambassador to this exceptional company.

Technicians were thoughtful and did a thorough check of Split units. They took time to explain the steps they took to evaluate each unit and how the units operate in winter months. They are an outstanding team!

I went to Thermall based on the reviews here and was very happy with the results! I had replaced some parts in my system based on diagnosis from another contractor but my heat pump still wasn't working. Rafael from Thermall came out and gave me a thorough diagnosis, showing me what the other guys had missed. He showed me exactly what he tested and why it was not working properly. He didn't hassle me or lecture me when I said I wanted to replace the part myself. He also didn't try to act like a salesman or tell me to needlessly replace working parts, while the previous contractor had told me that my perfectly good 5yr old indoor coil was at risk of 'imminent failure' and shouldn't be used until replaced for $6k. If my system breaks down again at some point, I will call Thermall first!

I had semi-annual maintenance check on my heat pump and it went well. Technicians were prompt and efficient
