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"

"If you are in a jam, up against the wall, desperate or just plain don't know any other plumbing resource, then call Bonney. They are fast, courteous, professional - and outrageously expensive.
We called for plumbing help Friday AM and they sent someone out Monday. The plumber was here first thing, diagnosed the problem and wrote up a proposal. It was steep, but he was ready to solve all our plumbing problems, one stop and no more fuss - so I approved it.
In less than 90 minutes he had cleared the urinal drain and installed a new kitchen faucet. The faucet is exceptionally ugly, the worst Home Depot model possible. My mistake for accepting his choose A,B or C option. Although he indicated he would have to remove the urinal from the wall to access the drain line, I think he had a change of mind - the drain was rodded through the outlet after all, no removal - about 10 minutes work.
The bill was $1260. The (ugly) faucet was a $100 Home Depot special, call it $260 with steep contractor markup. That means his 90 minutes of labor was around $1,000 or $666 per hour. I wouldn't pay a divorce attorney that kind of money, even if I was Gwyneth Paltrow!
No complaints about the work or the professionalism - but man that price.
As George Bush once said, and quot;Fool me once, shame on you. Fool me twice, ... I won't get fooled again.and quot;

"Keith, a consultant, came out, explained the different products, showed me where my system was failing, explained the cost and arranged financing. The next day, the plumber came out, removed all old products, cleaned area and installed new. He arrived on time and completed the installation on time."

"I had them for years. They installed my furnace and air conditioner. They service it every year. The furnace is 10 years old. I have the annual contract for both. I don't remember the cost exactly. Everything works fine. If I ever had any issues, they send somebody back to look at it. They work like a lot of these jobs where they have a window, like 12-2 and 2-4."

My wife and I did a thorough search in getting the best A/C Contractor in the Sacramento area.  The search included Angie?s List, Better Business Bureau, California State Contractor?s License reviews, personal recommendations from neighbors and friends.  After all our searching we ended up going with Diamond Heating and Air.   We signed the contract with Bob Weatherford who is also the owner of Diamond Heating & Air.

Both my wife and I were especially impressed with Bob?s thoroughness in explaining the type of system we really needed, the SEER rating of the equipment, and the best way of replacing the existing outdated  heating and cooling system, inadequate insulation, and faulty duct installation.   These were all good suggestions in transforming our home into a more energy efficient and comfortable environment.   Also, it was pointed out that some of the existing ducts became loose and disconnected.  Fiberglass insulation was blowing into one of the rooms.  The outdated  ducts were installed many years ago, and were poorly installed, wasting lots of energy, and the duct work was hanging too low below the floor joists.  

Bob suggested that the new duct system be relocated and strapped contiguous to the floor joists which would allow us to walk underneath the house so we could better utilize the space for movement and storage.  Another big task involved the installation of new attic insulation.   This was a big job that required the knowledge that Bob has as being a Licensed Building Contractor.  

Again, the thing I appreciated the most was Bob?s honesty and the effort he made to make things right.  Bob and Elaine worked hard to qualify us for the SMUD low interest rate financing and qualify us for the rebates that SMUD and PG&E were offering.  This helped us tremendously in bringing down the costs of the project.    My wife and I are extremely happy that our home now has an excellent home energy assessment from SMUD and PG&E.  We expect that our annual electric savings will be significant.  We are very happy to recommend Diamond Heating & Air to our family and friends.
