"Someone quickly came out to diagnose the problem. They were able to determine what was wrong, fix the immediate issues, and provide additional future recommendations. We would use them again."

"Just had the initial diagnostic visit. I was given terrible news (I'll probably end up getting a new furnace $$$), but the technician Ricky was wonderful. He was extremely polite, professional, and friendly. He did a very thorough inspection and then gave me a very thorough explanation of the problems. This included photos he took on the spot of some internal parts (oil leakage, heavy dust & dirt, stress markings).... at no point did I feel like I couldn't trust what he was telling or showing me. He answered every question I had. He went into the "attic" of my Eichler to check the ductwork (via a 14" hole in the closet ceiling, into space so shallow and tight I have no idea how the ductwork was ever even installed), and came out with photos to show me. The company was easy to work with when I had to change appointments, sent me email and text confirmations of everything, and gave me a day-before reminder of the appointment. I had an 8a- 11a window and received a text at 7:50a letting me know the technician was on his way, with a photo of him included. Perfect, perfect, perfect. The visit was $89 but reduced to $39 because I signed up for the MVP membership: $107 for a year which gets me all kinds of free services plus discounts on everything else. It even includes services on my water heater which they did not install! Additionally, they have some really good guarantees, MVP or not. Before leaving he called the office, explained all he'd found, and handed me the phone to set up an appointment with a "comfort specialist". Ariel (on the phone) was also extremely polite, professional, and friendly. These people are trained right! Or they're hiring very well. So, I will be meeting with someone to discuss repairs vs. replacement options. No repair work has been done yet (although Ricky did do a temporary fix that is allowing me to get some heat), so I can't fully review the company. But thus far I'm 100% pleased. This is probably the best experience I've ever had with any kind of repair technician. I've never used them before and have also never written a review before. The experience was just that good. I'll write another when I've finished with them just to give a full review, but so far perfect!"

"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!

"I had an emergency water break to my house on a Sunday. Bill Bellas contacted me first by e-mail and then by phone agreeing to be at my house with an hour and a half. Bill brough his two sons to help. He had to dig and sauter to remove the old pipe and then shop for new parts but the project was completed in under 2 hours! He was fee was VERY resonable and the Sacramento City Water department came out the next day to check the work. The four inspectors with the water department said that he had done an excellent job and that I got the deal of a lifetime. My neighbors all have his business card and we will use Bill Bellas in the future!"

"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.

"Called Laura late Friday night and left a voicemail. She returned my called first thing next day and had the low refrigerant problem fixed by 9:30 AM. She's great. Call her."

"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."

"Although the heat exchanger was still under warranty - the labor intensive job to remove the old one and install a new one wasn't. The labor was $929.00 to complete this all day job. I decided to replace the inducer motor at the same time since it was only a matter of time until it failed. I called Zak - the general manager and he agreed to give me a long-term customer discount. Steve Brown, my service technician notified me that morning when he would arrive and was right on time. He was easy to work with, showed me the wear to the units and explained what he was doing throughout the installation. After removing the heat exchanger, Steve pointed out the evaporator coils needed to be cleaned and gave me a discount for that work too. No one likes an expensive HVAC repair bill, however Ray O. Cook worked with me to ensure it went as smoothly as possible. I highly recommend them and will continue to use them in the future."

"Excellent! Dawn was so helpful and scheduled my visit for the very next day! The tech diagnosed the problem and fixed it. What an awesome company! When I remodel and put in enteral air and heat this will be the company I use. So very happy with Comfort Solutions!"

"The tech ran into some challenges, but he got everything working just fine. I'm very satisfied with his service."
