Get matched with top boiler or radiator heating system pros in Sacramento, CA

"Very happy with my experience so far. Goldenaire called back quickly to schedule an estimate, then the owner (Ken Golden) came out personally the next morning and provided a detailed, written estimate with different options to help make things more affordable. He was also very willing and open to answering my questions. (One of the other companies that gave me an estimate just scribbled a few notes down on a piece of paper and seemed reluctant to discuss details or answer questions).
Two days after I gave the go-ahead, the Goldenaire crew was at my door for the installation (at exactly the promised time -- 7 am!). Job was done by around 3 pm. The lead installer Kenny was very courteous and professional. I believe he's the owner's son, and I'm hoping he takes over the business eventually as I would definitely hire him again in the future. Speaking of which, this company included 5 years of labor as part of the system warranty. (The other companies that submitted estimates only included a year of labor).
I won't know how well the system works until this summer, but will update this review if anything about my experience changes.

"Everything went well. The system will go anytime, and I will definitely give them first try on replacement. I trust them."

"Garrett and team were excellent, they provided top professional service at a reasonable price. I am very happy with my new furnace and the whole installation process. Highly recommend!"

"Definitely my go to company when it comes to my Heating and Air Conditioner! With this heat and my unit going out they came in a fast and timely manner and got straight to work! They knew exactly what they were doing and fixed my AC. Very professional and courteous!! I will definitely recommend to anyone i know and will be calling them for any future issues!"

"They come out and do the service okay. They are too pushy to try and sell you on a new heating system. You can make an appointment for a new system and they don't come out. They're known to be high. I think they are high. When they come out, they will call you ahead of time."

"Air conditioning in one zone stopped working over very hot weekend.  Called three companies to get a quote on possibly replacing both zones before I spent money on repairing a 17+ year old unit.
Diamond was the first company with availability.  Before they came over to give a quote, Bob called to ask me a few questions about the nature of the problem.  He speculated over the phone of what the problem might be and what the cost of fixing it would be.
He arrived for the appointment at the appointed time and proceeded immediately to fix the unit while talking to me about an estimate to replace both zones (2 systems).  He spent extra time hunting down an electrical connection issue in the unit and when done, checked out the flow readings of the system.
$258 dollars fixed the problem.  Since I had scheduled him for a quote, he offered to remove the new part that he had just installed or I could leave it in and if I decided to buy a new system, they would credit the repair of this unit back against it.  I elected to have him leave the fix in place.
Bob quoted me an exceptionally good price per unit for a quality Lennox system.  In fact a competitor who came the following day said that he wanted to see a copy of a written quote because Diamond's price was too good.
Although I've decided for the time being to not replace both systems, I would select Diamond Heating and Air in a second!

"The team of four was very professional and performed an excellent job in a record period of time. Just one day to take the old furnace away, replace all the old boots and duct work and install the new furnace. They paid a lot of attention not to damage or dirty the floor/carpet. I am very happy with their performance. They may not be the cheapest on the block but it was all worthed and you only have to do that once in your lifetime."

"Russell came out the same day we called. He looked at our OLD water heater and recommended we install a new one and also recommended a Hot Water Recirculation System. It was installed the next day - promptly and efficiently. We have hot water ... and quickly. Great service!"

"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.
"

"They showed up and had it fixed within minutes, however 2 days later it went out again. They came back and again fixed it pretty quick, however it went out the next morning . Other than telling me the system was old they didn't say the system needed anything, but did try to get me to make an appointment with their sales guy. My guess is that the service guy gets a commission if customers by a new unit. I think that would explain why they don't waste time fixing old systems for a few hundred dollars and more time trying to sell you a new system for several thousands."
