Best Air Duct Cleaning in San Francisco CA

In the last year Ongaro + Sons have installed a new furnace, A/C, copper water lines and a tankless water heater.  Each job was done to perfection. Their support staff is wonderful as well.  A big shout out to Ian, Travis, Mike, Nick and Juan for their excellent work.

We reached out to replace our smoke detectors (reaching end of life, annoyingly sounding off periodically).  They scheduled us for the very next morning, and Richard showed up right in his designated time slot. He was courteous and knowledgeable.  He diagnosed the situation quickly, and had replaced the whole system in no time. He was so good that we asked him to fix another electrical problem we were having with a light switch (which he also did quickly and efficiently).  Strongly recommend.  Thanks Richard.
