"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!"

"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."

"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!"

"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!

"Our Service Tech, Alex Peck, arrived on time to perform the annual check up & tune-up of our HVAC System. He was very professional and following the Tune-Up asked if there was any other items that needed done or looked into that he could take care of. His services were very much appreciated and very professional. Lee"

"Our experience with Ray O. Cook went very well!! Our HVAC system was the original when the house was built over 40 years ago. My husband's excellent Do it Yourself skills allowed him to maintain it and keep it running all these years. We received estimates from 5 different companies. Although the other salesman/estimators were good, Paul was the best. He explained all our options more thoroughly than the others and his recommendations for installing the HVAC system for our needs and house size made the most sense. The price was very reasonable and fair. The installers, Willy and Rick T were awesome. They both worked professionally and took the time to answer any questions either one of us had with the install process. They also did an excellent cleanup job. Erick, the install manager was very knowledgeable and helpful. The insulation was put in by Sierra Wes, a company Ray O Cook contracts with and they did a great job also. Lastly, the Ray O. Cook logo of a flaming O is super cool!!!"

"I purchased the deal thinking that the fireplace would then be able to provide heat for my house. After talking to the very helpful staff at The Hot Spot, this deal does not provide any extra heat. The type of insert I need is about $3,000 and not currently in the budget. I am requesting a refund within my 30 day guarantee from Angie's list."

"Mr. Ferrell first connected his computer to my computer via internet and worked for quite a few hours trying to determine what exactly was wrong. The next day he continued working from his computer for several hours. He determined he would have to have my desktop tower to complete the repair. He and my son met in Huntsville to exchange the tower. He then cleaned up a lot of what was wrong and reloaded Windows 10. He deleted the D: drive which had way too much memory allotted to it. The tower was returned and I plugged it all back together and it is working better than it did when I first purchased it. I would use him again and I recommend him highly to anyone needing computer updating and/or repair. His work is warrantied and he is very personable, knowledgeable, and helpful."
