Get matched with top boiler installation pros in Mather, 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."

"The salesman was chummy; the bid submitted was in the middle of the pack pricewise. With Brower's great reputation that was enough for us. Before we committed the salesman threw in a free upgrade of one A/C from 2 tons to 3 tons and offered to enlarge our upstairs air return (the 3-ton A/C was for upstairs) to improve airflow. This was done over the phone - a key point. The next step was a pre-site inspection. No problems arose, and I asked the guy if we really needed to replace our existing Lux thermostats - as the salesman had said - and this guy said we didn't need to. I mentioned the salesman upgraded the upstairs A/C to 3 tons and this guy suggested we get that in writing on a revised bid that removed the thermostats. We did so; the new bid was $200 less. Next was the install. When scheduling it I said that we could not let workmen in before 9AM because we have to drop kids off at different schools at 8:30. I also wrote this on a fax I sent the day before the job started as I had heard nothing to confirm they knew this. At the end of that same day I called to touch base on the time constraint as I still had heard nothing; I got a different salesman who said he'd let the installers know since they usually start at 7AM. At 7:20AM the next day the installers arrived, oblivious to our time restriction. They started outside and we let them in the garage - but not the house - while we were shuttling kids. We let them in the house at 8:45 and things went smoothly from there. At day's end I asked when they were going to enlarge the air return and they were all "Huh? You better call the sales guy and get his OK on that". I did and I got an EARFUL from him. The salesman was irate that I was asking him to back up his verbal commitment to enlarge the air return for free; he was mad that I couldn't let his guys in at 7:20, asking "How fair is that? I paid my guys to do nothing for 2 hours in the morning and you ask me for this?" He finally, grudgingly relented. But I have NEVER been so insulted by a contractor, and we have used LOTS of contractors. The second day of install was smooth. The guys showed up at 9AM, worked late and did an extra task - covering outside pipes to the A/Cs with a sheet metal cover - which I asked for as a paid change to the bid the prior day. There was stucco and drywall touchup remaining but overall I was pleased with the work. The installers even included extras where needed despite the extras not being explictly included in the bid. They cared about doing it right; cost was not a concern. But the horror that I met when I went into the attic later! Debris all over - screws, straps, sheet metal pieces, even 4' of old metal ducting they had replaced just sitting there. I spent 2 hours cleaning up, and was so mad I sent an email to Brower with lots more detail than this. Brower responded with gusto and did what was needed to rectify the situation, fixing about 6 small issues I had found."

"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!"

"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."

"Very good installation, one that will still look good in 25 year. Team performed above expectations."

"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."

"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."

"I purchased the deal and because I wanted to convert from traditional wood fireplace. They could do the gas installation in the fireplace but they could not assist me with the damper."
