Get matched with top boiler repair pros in Applegate, CA

"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!"

"Kermit and his son showed up quickly on the same day I called on a Saturday to replace my water heater and expansion tank. They were both very friendly and professional and performed the exact service I needed without any up-sells or other kind of pressure like a more expensive tank with unnecessary additional warranties. They replaced the old water tank and installed the new one very quickly and I was very happy with the work. Very efficient and professional and I recommend for any plumbing job. Am very happy with my Bradford White 50 gallon water heater and it has been working like a charm for months. It seems to be performing better than the old one too as the water heats up faster and is hotter at the same setting we had before. Thanks a lot Kermit!

"Wonderful! They came out quickly and on time. Their repairman was very good, very professional, and really a nice guy. Without going into detail it was apparent that the warranty co. was trying to charge over $1000 for repairs that weren't even needed! They had told my son that their compressor was ruined when all it needed was (I think) a new start capacitor! Plus the warranty co. people told my son that they would HAVE to perform a PURGE which they would have to agree to and that the PURGE wasn't covered by the warranty and would be $800! Bell Brothers came by, fixed the problem and that was that. Cost: around $300"

"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."

"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.

"Very professional. Fixed my leaky shower valve and handles. Also replaced all my shut off valves for the bathroom sinks and toilets."

"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.

"I highly recommend A/C Girl to anyone that needs help with their air conditioning or heating needs.  They are very reasonable, accommodating and pleasant to work with. 
Our water heater rusted out and needed to be replaced.  The A/C unit for our house runs parallel to the water heater and the pipes from the A/C unit blocked access our water heater.  The water heater repair company requested that the A/C pipes be moved so they could replace it.  A/C Girl came out, moved the pipes and the water heater was changed.  I called A/C girl back and they promptly replaced the A/C pipes and gave our unit a tune up.
 
They were willing to work with our schedule to perform the needed work.  We kept changing dates on them due to problems encountered with our water heater installation.

"Took longer than specified and there was an accident with the gas line, however, the tech took respiring the spot and fixed everything and made it “right”. When he left I felt he had done a good job and I was very satisfied with furnace."
