I am the maintenance coordinator for a property mgmt company with 400+ clients. ATS is our go to heating/cooling vendor as a result of prompt, courteous, knowledgeable and appropriately priced services — 24×7 !

My AC unit broke down last summer and called ATS to come out and take a look. They did a temporary fix to make sure the unit would still run while they were working on a quote to get the unit up and running right. They gave me a great quote, better than anyone else in town and were out within three days to fix my AC. They were extremely courteous and friendly, and highly knowledgeable. They educated me on my new unit and how everything worked and made sure I understood before they left. ATS came back out in the fall to insure that my heater was working properly as well. They are great and so easy to work with, I would highly recommend them to every one.

Their staff is pleasant to do business with. They answer their phone and return phone calls ASAP. I would not hesitate to refer them. 2 Thumbs up.

Ronnie came out today to do my checkup. I used a Groupon for this service. He is one of the most thorough technicians I’ve had the pleasure to meet! He is totally trustworthy and honest, and did the most thorough job I’ve ever seen. I also bought a Groupon for my mom, and I’m telling her to request Ronnie when she calls for her checkup! Thank you ATS! If I have trouble in the future, I’ll be calling for Ronnie to come out!
