This Company gave me a very competitive price and a Prompt date to start and an exact time they would need to complete the job. The Workers that did the job were great guys and hard workers. They were courteous and helpful. They worked late the last day to insure the job was completed when promised. The office personnel were also very kind and helpful when asked to provide additional paperwork. I absolutely will recommend this company too anyone needing heating or air conditioning installed.

I have been a homeowner in the Milford, CT, area since 1974, and, through the years, have had difficulty finding a reliable and trustworthy furnace and central air service. I am in my fourth year with this company and couldn't be more pleased. I have the full service contract and am very happy with their promptness, professionalism and courtesy.

I bought & moved into a home about 1 years ago, & had problems with the furnace the first winter, 2019. Air Specialties was recommended by my plumber. The technician, Jim, came out & discussed the problems he found with me & did repairs as necessary. Still had a few instances where the furnace would shut down but got through last winter. At the beginning of this winter, 2020, the furnace was just not reliable so decided that I should replace it. Bob came out & wrote up an estimate, & when I finally decided to go ahead, it was installed within 2 days. The two technicians, John & Pete, were here
