"Arrived on time and finished the job within a hour. Also helped restart my gas water heater."

"Starting with JP the senior technician, the inspection and documentation of existing conditions was thorough, knowledgeable, and complete. Moore recommended the replacement system that would be more durable and require lower maintenance over time, and wrote a detailed proposal with a floor plan documentation. We were given financing options at the time of signing the agreement, as well. The team- five technicians!- were properly suited with protective gear and followed COVID protocols at all times on our property, inside and out. They wore shoe protectors while inside, kept us fully appraised at every task (all interior registers replaced in 11 rooms), and were extremely respectful of our space, privacy, pets, and kept noise and speaking to low levels. (our extremely friendly indoor cat got lots of attention from the team!) The work required three days to fully replace all ductwork in a two-story home with attic and crawl space, and Paul the team leader would check in with us each morning with a briefing of each days' activities. The entire team was constantly in learning mode, with the senior technicians mentoring and teaching the younger team members, which greatly impressed me. They finished on time and without any delay or disruption; they cleaned each work area and removed all debris, packaging, and the old system. We've owned this house for 20 years, had many repairs and replacements, and Moore has raised the bar so far for quality and value. While they were the middle bid in terms of overall cost, we believe we received higher value that even the highest bid. I can strongly recommend them to anyone planning repair work on their existing system, new installations, or maintenance. After getting few responses from HVAC contractors working in new homes in Sonoma County, we were pleased to know that Moore specializes in existing homes and responded to our online request within minutes. I'd be happy to share my experience in person, if required. Martin Waldron Sebastopol, CA"

"I would highly recommend Ray’s Rescue Plumbing. He was very clean, prompt, courteous and knowledgeable. We had several issues ranging from leaks, repairs and installing a tankless water heater. Ray’s prices were competitive and he actually saved us a few thousand dollars from a previous bid from a ‘not so honest’ plumber."
