I had called them to get a second opinion from a previous technician that came out with a diagnosis. So, glad I did, there was nothing wrong. Lilliana was great, and Tom was superb!

This company and its employees are very professional and helpful. I have never had a negative experience with them. Barry came out to do a check up on my AC system. He was friendly and so helpful in fixing a minor problem. He was able to come earlier than expected and called ahead to be sure that this was alright with me. Even the young lady that took the initial call was very friendly and helpful in getting what I needed scheduled.

After a bad experience with another company, ATS came to the rescue and I've been using them ever since. They are very responsive and professional. Their annual service contract is wonderful and gives you comfort that your system will be working well going into summer or winter. Good value.

Working ATS Mechanical Heating & AC has been great! They serviced our old system a few times until we needed to replace it. As we discussed options for a new HVAC system they were very informative, thorough, transparent, and accommodating. The installation was fast and they even cleaned up the insulation and debris that came from our attic. I'd definitely recommend reaching out to them if you're looking for HVAC help in the area.

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.
