The result is always perfection!

I’ve been a customer for several years now and FourStar never disappoints. Even on last minute call emergencies, they accommodate me as soon as possible. They are always on time and get the done job efficiently. Their staff returns calls promptly and always guides me to all available options. Tasos (the owner) gives expert help over the phone and if that’s not enough a technician will immediately be sent out to solve the problem. The techs take their time to explain what went wrong and even give me advice on how to keep the AC running better in the future. I’ve had numerous installations completed with FourStar in both my home and business and the result is always perfection

Professional Team

Four Star Air Conditioning changed the whole HVAC system for my company's office. Two big units needed to be installed on the roof of the building. They were very professional and everything was changed without inconveniencing anyone at my office and they were very expedient about getting the job done. It is noteworthy that it was during the summer months as well. I would strongly recommend them
Gena B., Queens, N.Y. -

Very pleased with the service

I had a 2nd floor, 5 bedroom AC/Heat Daikin system installed, very pleased with the service. The DAIKIN technology is amazing, each room has its own wireless thermostat, and keeps everybody happy. The owner Tasos is a real pro, takes pride in his work, I recommend without hesitation.
