"Frank and his team did an excellent job from start to finish. He arrived the same day I requested an estimate and replaced my 30 year old system 3 days later. The new HVAC is wonderful. No mess or damage, great price, and great quality you would expect from a small privately owned company."

"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."

"Timely, efficient, response. Identified a minor mold issue and applied appropriate treatment. Poor quality filters on equipment left a film of fine dust everywhere near a vent. Recommend upgrading vacuum filters to finer screen."
