"5-Stars for Shawn at Precision Air! We were looking for a dependable and experienced HVAC technician when it came time to replace our furnace and add AC. We discovered Shawn at Precision Air and couldn't be happier with our choice. Shawn was incredibly professional and responsive from the start. He listened to our requirements and explained all of our choices. He also provided us with a detailed and reasonable quotation. Shawn got right to work on the day of the installation and arrived on time. He took great care with his work and made sure everything was done correctly. He also took the time to instruct us on how to use our new system. Even after the installation, Shawn's follow-up was excellent. He contacted us many times to guarantee that everything was working effectively and to finish the final inspection after being paid. For all of your HVAC requirements, we strongly suggest Shawn at Precision Air. He is a real professional who is proud of his work and who we will surely hire again in the future."

"Elsy ( I believe she was the plumber from your company via Angi) arrived as scheduled, on Saturday, 09/28/2024. She attempted to repair my garbage disposal unit but was unable to do so as the unit's wiring was worn out. I advised the unit is 40 yrs old. She recommended to purchase a new one. We made a trip together to the local Home Depot store and I purchased the same brand s she recommended. She installed it in record time (within the 2.5 hrs) and completed the job. She also cleaned the work space and carried the old one to my recycling bin. Very satisfied with her work. Also, I want to know if I will receive a billing statement for my records? Thank you for your time & assistance."

"HE IS VERY EXPENSIVE, BUT DOES GOOD WORK. COMES OUT WHEN I CALL, AND GETS THE WORK DONE. DOESN'T MAKE A MESS. HE INSTALLED NEW TOILET AND SINK, DID GOOD WORK."

"I own a business and had a company come out to fix our air conditioner. They came out 4 times, charged for all those time and the unit still was not working properly. I then decided to try someone else, so I called Thermotech on the referral of a friend. They came out, diagnosed the problem within 10 minutes (it was an old crumbling circuit board), showed me that bad part, ordered it and had it fixed in less than 24 hours. We have not had a single problem since! I was so happy with their service that I ended up using them for my home HVAC system.. I even referred them to a family member and they did a home install of a brand new HVAC system and they were very happy with the price, install, workmanship & fair pricing. Thermotech has found a customer for life with me. I have had so many bad experiences over the years with other companies telling & thermotech has been a game changer."

"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!
