"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."

"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!

"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."

"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!

"Jim did a great job. He quickly assessed the problem and then took our unit with him to work on it more. When he got back to us, the fix would have cost more than it was worth. He gave us options for a new or refurbished PC. We felt the refurbished was a good deal and chose that. He came back and set that up and we are very happy with it. He then took a look at my laptop and again took it along. He tuned it up and installed a speed upgrade we wanted. Of course, we paid extra for the new unit and upgrades, but we thought the price was very fair. Jim seemed very knowledgeable and responsive. We will definitely call him again if we need any computer services."
