“A&S is simply the best. They have been doing yearly service on my furnace at my shop for years. They installed central air at my house 2 years ago. From service to installation, they always perform. The techs are all professional, polite, and proficient in their trade. They always show up on time and do a thorough job. I highly recommend this company.”

“I've been using A&S Nathan since moving to Stratford, CT. They service my A/C and furnace every year and I have needed them once or twice for a furnace repair. The office people are wonderful to deal with and the technicians they send for service are very knowledgeable and super great people that you can trust. From my experience, I am confident that I am getting the most honest and best service possible. Thank you to everyone at A&S and a special thank you to Dan who has serviced my A/C and furnace several times. Today it was the pipe going out the chimney. Awesome job!!”
