"I signed up to have one of my HVAC's covered by Tim Kyle. I used the electrical service for over 20 years and the service is exemplary. This is the first time I used the HVAC service. I was impressed. It was a great job performed by a knowledgeable, pleasant tech who was available to answer any questions I had. Most important the HVAC was up and running before the 100 degree days to come later this week. Thanks guys"

"Ductz of the Upper Bay Region cleaned my ductwork today. The team was professional and friendly. The cost was stated in advance as a firm price and not an estimate. They took before and after pictures which I found very helpful. The owner and his team went above and beyond to suggest ways that I can best maintain my A/C system to minimize the need for cleanings in the future. I recommend them highly."

"I had a gas leak issue and it was later identified that leak was on the outside of my house and Washington gas company fixed it. In the meantime I had approached Michael Bonsby to come and check if there are any issues inside my house. The contractor showed up and said that there is no issue with the HVAC and the pipes that are connected to the HVAC. He was suggesting that if there is a leak in the pipes that are inside the drywall, I have to contact a plumber. I wish the contracting company advised me that I may need a plumber in case the leak is in the pipes inside the drywall."

"Great! He provided additional information, suggesting I install a UV Light Air Purifier to my HVAC system. Which would help eliminate the possibility of mold growing in my vents."
