Get matched with top boiler installation pros in Lincoln, CA

"Great work, provided a good explanation of unit choices, competitive pricing, all installers friendly. Only hitch was thermostat installed in wrong place but no problem coming back out to move it to the agreed spot. Good cleanup."

"They installed a furnace and had to keep coming back to adjust it and even replaced a part. The warranty ran out a year later. But now, a year and a half later, they replaced it free of charge with a different brand."

"My water heater went out and needed a new one Ruben and Maurice came to my home And quoted me on my options I ended up going with a new style tankless water heater I can’t be happier with how it performs and the installation process Will definitely recommend this company to my friends and family"

"They had a good program for heating and A/C like for $100 they come out and check in the fall to make sure the heating is running right and again in the spring to make sure the A/C is working right. They did their job. It was cheaper than anyone else and I got 2 services. The only thing they could do better is give me free heating and air conditioning."

"A pureonics water conditioner was installed in February and about a month later we notices a leak.  it was repaired the day after we called."

"I have an old pressure relief valve replaced today. the service person was great, and the installation went really well. My main complain was the price after I did an online comparison. usually, the PRV installation will cost around $500 on the high end, but Bell Brother charged me $1600 since the new valve does not fit the old pipe, and they needed to redo the pipe. My family has been using bell brother for many years, we trusted their workmanship, but the markup is just too steep to justify. I definitely learned my lesson, for small jobs, will use home-advisor instead."

"When it became clear that my existing HVAC system needed to be replaced, I initallycontacted thecompany that was the original maintenance contractor.  They made a proposal for system replacement, but, would not give me a paper contract explaining the complete work to be provided.  Indeed, said contractor proceeded to try to sell me additional items I did not want or need.
I subsequently called Diamond for an estimate.  Bob came to the house and thoroughly explained various options and provided
written contracts for the alternate proposals.  The straight talk approach was really appreciated (especially after the snake oil salesman from the prior vendor).  After a day's review, I authorized Diamond to proceed with the installation.
The Diamond staff showed up on time and finished the installation by the end of the second day.  They were extremely professional and patiently explained what was happening at each stage of the project.  Behing the professional staff, Bob an Elaine Weatherford remained in contact to make sure that I was happy with the work.
My only concern after the project was completed was the interaction between the new system and the smart vent system.  Bob and his staff made sure the my concerns were resolved.
I unconditionally recommend Diamond HVAC sysems to anyone who wants to depend on dealing with honest, no nonsense, business professionals.

"Outstanding! Bid process fully transparent, proposal guaranteed labor, materials and equipment for decades to lifetime. Installation team of Carlos and Roland outstanding. Carlos kept me informed throughout and got my input into key decisions. Nice people, hard working and honest."

"This was a two day job. The two men, Willie and Jose, who did the work were competent, courteous, and professional. They were responsive to our questions, did a good job of tidying up, and worked diligently. I think the work went very well. Installation was completed yesterday, and so far everything seems to be fine. Willie and Jose were knowledgeable about what had to be done and understood our concerns. We have no complaints at all, and would recommend them to friends and family who need HVAC work done."

"Contacted them. They sent us links to the gas inserts. We picked the one we liked. A few days later they sent someone over to install it. He did a good job. Cleanup everything. Used it the whole winter. No issues. Love it.
