"The person who handled my call was friendly and professional. She told me a technician would be at my house in 4 hours and called me when he was on his way. The technician was outstanding, on time, professional, friendly, and quickly diagnosed and fixed the problem...best of all, he didn't try to sell parts/service that I didn't need! Best experience with an HVAC company I've ever had."

"I always recommend Anton's to family and friends who need HVAC services. Their prices are reasonable, and their service is top notch! All of their technicians are very professional and considerate and they don't try to sell you things you don't need. Ronan just came out this morning to do our annual A/C inspection. The service was excellent as always. He took the time to explain everything and made recommendations. I never felt pressured, and I trust this company to take care of my HVAC needs. They've got a customer for life!"

"Had new hvac, furnace, and hwh installed. Furnace had a couple of air leaks between a coil and furnace which I fixed myself. Hvac was spot on. Hwh failed first inspection, but was corrected in same day. For the premium price paid, these issues should not happen. Quality 4.5 because of these issues, same goes for value. Customer service is very good. They are very professional, work looks very good, clean worksite afterwards. I would recommend, but don't think about negotiating price with them. Their labor is very high."
