Jonathan spent a good part of the day doing the annual maintenance on our four AC units. He was efficient, courteous, thorough — in one word, terrific. Thank you, Jonathan, for the superb service you provided!

Outstanding Service

Jim from Lincoln, MA

Stefano provided us with a wealth of information about our current system. He also gave us some good ideas about our future planned 3-season room addition. Not only is he obviously very knowledgeable, but he also has a very engaging personality. It was a pleasure to work with him. Clone him!

Competent, efficient, friendly

Dennis from Lincoln, MA

Jonathan arrived within the scheduled time window. He had not been to our home before, so he asked me a few questions to make sure he understood our HVAC setup. He then explained what he was going to do and went to work. He was very careful and made sure he did not track dirt into the house.

Good service, price not so much

Jack from Lincoln, MA

A knowledgable person answered the phone, the technician who responded seemed to know quite a bit about my heating/cooling system (which I inherited), and did a good job explaining it when I asked. My only problem was with the cost. Never had suc a complicated system before, so I do not know how the charge for parts compares, but I was shocked.

Great Service from Abdel Nouirja

Abdel as punctual, friendly, knowledgeable and thorough. Abdel spent 5 hours fine-tuning our four units and we are good for another year. Highly recommended.
