"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"

"Good folks. The job, replacing a gas water heater, turned out to be more complicated than was anticipated. They were flexible and adapted quickly to the situation, The results are excellent. 5 stars. As far as "value," hey, everything is expensive these days."

"Finally an honest Solar company!! I went through several companies trying to get quotes for one of my properties, either they were ridiculously expensive or they didn't return my calls. A friend of mine referred me to Mega Sun and I have to say I am very pleased. Within a couple days from the initial phone call I already had an estimate and once i decided to go with them the installation was completed in one week. Its been a little over a month since they completed the install and everything is working smoothly.

I was amazed at just how great the customer service was. I just want to say thank you to the whole team who helped out, I really appreciate all your hard work. Now I know you guys are the ones to call for all future jobs."

"It’s been a while that I wanted to have a company that can come over and check the house for any problems that increased my monthly bills and to fix them at a normal price. I came across this company and I scheduled a meeting with Ezra and Charlie to come over and see/check. Ezra and Charlie checked the house for more than 2 hours and they found out that some of the windows were old and needed to be replaced with new ones. In addition to that, they recommended me to remove the water heater and to install a tankless system that will provide me with hot water only when I need and by having that, my bills will be reduced.The Quote that I got from him was good enough (to my opinion) and I retained them for the job. The work that they did proved to be good one and I see that in my monthly bills. It was a 2 weeks work and I am completely happy with my decision to hire them."

"I highly recommend Mike. He installed a tankless gas hot water heater for us & repaired a faucet in the second bath. He was the most cost effective by far of the three estimates I received to install the heater. Everything was done in a workman-like fashion, promptly, & with no mess left behind. He and Adan are very professional and on top of that, they are both nice people. Any other plumbing needs I have in the future will go to Mike & Penngrove Plumbing"
