Best boiler installation pros near San Ramon, CA

"This guy is a real pro! The original installer came out and gave up on the problem, and I never heard from them again. Duke came out, and diagnosed the issue in an hour. He even submitted the request for a part under warranty, received it, and came back to install it 2 days later. The cost was very reasonable. Thanks Duke!"

"I highly recommend this company!!! He responded within minutes of my searching for a plumber. He came the next day and installed a new tankless water heater. He also found a faulty electrical outlet and repaired it as well. Quality workmanship. I will keep his number. His name was Harry."

"Understandably and as expected all HVAC contractors were on high demand and all booked up for several days out, so no one in the area was available until the following week at the earliest. We called Mr. Diego Utor and lime everyone else he was also all booked up; however, he added us to his already full day and said he would do his best to stop over. Diego kept his word and arrived late afternoon that very same day. He quickly diagnosed the problem, which turned out to be a bad capacitor. He replaced the part and also checked the refrigerant level for us. Diego Utor is responsive, courteous, honest and his rates are very reasonable for his services. I would highly recommend HVAC Utor Services to anyone for all of their heating and air conditioning needs, whether it's repairs, routine maintenance, or new service installations."

"He checked and cleaned a wall heater and restarted it. Gave me good info and cleared up something that I was misinformed about by another company. He checked for carbon monoxide and made sure I had monitors for Carbon monoxide and fire. Very pleasant gentleman."

"The technicians that came to install our HVAC system were super friendly and accommodating to my many requests about locations of the furnace, vent pipes, the condenser wiring, piping, and the condenser itself. When I asked for a 90 degree boot feeding two registers so the piping could stay high, a technician made a run to a store and found them. I want to give a shout out to Danny Aguilar who installed the furnace with Edgar and Victor. Grant Duran with Jose and Richard did an amazing job installing the vent pipes. Finally Adolph Garcia with Gabriel and later several other technicians I previously mentioned all worked to install the AC system (condenser and its plumbing + electrical). They worked late into the day to complete the job. I was very demanding in where I wanted things installed and requested changes on a regular basis but in all cases I was accommodated."

"Tony kept in touch with me regarding arrival time, and showed up on time. When finished, he explained to me what he had done, and gave my tips on how to maintain the ducting system."

"He came out on time, gave an estimate which was the most reasonable. Arrived when he said. Tougher job than he anticipated d/t poor installation of previous unit so $500 added. Waited until we got to use the AC before writing review...it is noisy but plenty cold. They put paper over the hardwood floorsto protect them. Work finished in 2 days"

"Called these guys for what I thought was a Nest issue, and they discovered that my heat exchanger had cracked and I was better off replacing my very old unit with a new one. They provided me with a proposal the same day and I decided to contact a couple other companies for comparison. They confirmed Jazz's findings and provided me their quotes as well. Jazz's bid was very competitive and I was happy to give them my business. On install day, Jazz showed up with two other gentlemen and they wrapped up the installation in one day. System works great. Thanks so much Jazz!"

"Excellent Service from planning through Execution and installation to final fine tuning. The folks communicated well and explained every detail of the step. Got permit and inspection done. It was seamless. Thanks. R."

"Excellent service, personable folks, and experts at this rare
profession. While they are skilled at air ventilation systems, cleaning
furnaces and air ducts is what they have chosen to specialize in.
We moved into our new place and the previous owner never had the furnace
or any of the vents cleaned out. Dust had piled up over the years that I
refused to turn on the heater in fear of breathing all the fossilized
dirt. We decided to get a room heater as we looked around for a
reputable company who could help us.
