New Furnace and Air Conditioner This is the third time my family has dealt with A1 over the last 30 years. No high pressure sales yet offered competitive pricing. Installation team was timely, considerate and most importantly, did an excellent and neat job installing the equipment in tight quarters in an older home. Being an engineer and having actually helped a friend install a gas furnace, I have an idea of what it all entails. New equipment is so much quieter than the existing and I hope the quality matches that of the wo... read more

Installation of Ductless Air Conditioners and Central AC unit I am very satisfied with the service that I received from this company for the installation of a standard central AC unit for a triplex rental unit and for the installation of ductless AC units into a 3 story century home heated by radiators. The sales manager was very knowledgeable and experienced, responded to my questions thoroughly, customized the installation to meet my needs, and did not try to oversell me. The installation crew were polite and efficient and... read more

Fortunately he had one in his truck which he i... read more

Installation of new furnace, air conditioner and water heater All work was completed in less than 8 hours by 2 servicemen. The workplace after this installation was cleaner than it had been before this job. They also thoroughly explained all operations of the equipment at the end of the installation Ron Smith

Air conditioner maintenance Installed the air conditioner in 2006 when I bought the home. Very pleased with annual maintenance check by Mike. He is very professional and I have confidence and trust in his evaluation of the unit and his recommendations.

Air Conditioning Repair My air conditioner stopped working. Decided to try A1 and they came the same day and repaired my air conditioner. The prices were reasonable and the service was fast and professional. We couldn't have asked for better. Will definitely use them again the next time we need service or repair.

Last Scheduled Contracted Service Call Long time client. Last service call for A/C was not up to the standard we are use to.

An electronic initial was required on I-pad without any explanation of what was done. Service person did provide suggestion to change air filter on furnace before our Fall service but when asked if he provid... read more

Furnace service ! I am completely satisfied with my service call. The technician shoed up on time and explained everything to me. He spend a good amount of time cleaning the furnace and checking all of it's functions. Before he left he asked me if I had anymore questions for him. It was very professional.
