What Customers Are Saying

All I can say is excellent service. Absolutely will use ATS for my AC requirements moving forward.


We had new HVAC system out in our house and ATS went over serval options with us. This allowed us to make the best decision for our home and financially. Install was completed within a day.

Kaela B

ATS was great to work with. Upon scheduling the install, the crew came out got the mini split system working in no time. Very professional group. Look forward to using them in the future.

Chris O

ATS installed my Heating & AC system 4 years ago and has been providing routine checkups and maintenance services since. Quality service plus a valuable membership plan makes me a satisfied loyal customer.

Cynthia T

ATS Mechanical installed a Mitsubishi mini split system in my master bedroom, works very well and exceptionally quiet. ATS personal were very professional. Would highly recommend them.

Dennis B

The team at ATS Mechanical is first class. We have used them for the last two years and they have always been professional and extremely responsive. It is apparent that they truly care about the quality of their work. I would highly recommend them to anyone needing climate control work at their home or office.

Hal B

I love this company…I’ve tried others but this one is by far the best! They are honest, reliable, and give great service. I know I can count on their expertise!

Estelle T

ATS is the best heating and AC company ever! I had my AC, furnace, and ducts replaced in July, and the workers that did it were all so sweet and did a fantastic job! I also had Shaun come over to perform a heating inspection this morning and he did a very thorough job. I appreciate how he took the time to explain to me what he checked. All in all, I absolutely love how professional, responsive, and caring this company is. I highly recommend them!

Ashley T

ATS was very prompt in coming out to fix the issues with my HVAC system. Jordan was very helpful and informative, and he walked me through everything he was doing. He was up front about all the cost and gave informed answers to all the questions I had. We will defiantly use ATS Mechanical and AC again!


These guys are amazing, I initially was using another company but called ATS for a second estimate when I had work done back in December and not only was their quote a 4 digit number cheaper, they were very quick, professional and I have not had any issues with their work.
They came out today to repair the other side of my system and not only found the issue, got it fixed and had me back up and running same day. Their guys are very knowledgeable in HVAC and it shows in the quality and expediency of their work.

Kevin D

I have been using ATS Mechanical for several years now, and I have always been impressed with their service and pricing. The owner, Barry Granger, and his techs, Shaun and now Jordan, are super knowledgeable about our system (one unit serving three levels) and ensure it runs optimally. They arrive on time, send a notification when close, and follow up with electronic documentation. I am on an annual plan, which is reasonably priced and includes a discount for parts and repairs. Highly recommend them.

Rich B

Outstanding, professional organization. Owner personally evaluated heating/cooling loads for a replacement mini-split. A more applicable sized system recommended versus existing system, job cost estimate was very competitive versus other quotes. Install crew showed up right on time, very professional, job done right, great cleanup. Will no doubt use them again (and again)


Professional, on time, and quality of service was excellent. Installers cleaned up and left nothing behind. Very happy with service from start to finish. ATS has also provided repair services before the install and I was always very happy with each visit.

Jerry M

Great communication, fast appointment and professional technician. Explained all the steps of repair and the cost was great value. My new “go to” company for HVAC services.

Robert J

Overall experience was great from start to finish. Would highly recommend! Was not the typical sales pitch in and out kind of deal. We were informed about the product we were going to purchase and given all the information we needed to make the right choice for our home. Nothing was forced on us, everything was based on facts and shown with proof. Our rep from the beginning was great! Thank you Brock.
