"First Alfano Mechanical Inc. came to my home, said they would do the job and called the office told them to get me on the schedule ASAP. Gave me a price per hour. Well he never called back to this day. Would not recommend them to no one. Job was to HARD for them. Also I had my AC on my worry free with PSEG and they made me take it off because they would not work on my unit in the tight spot that it was installed in my attic 11 years ago. SO WITH THAT BEING SAID: Celestial Air HVAC called when I first contacted Home Advisor and after not hearing back from Alfano(which I would not have hired because they didn t live up to anything he said while here), I called Celestial(and so glad I did) and they came the next day, said it was a hard job and a mess but nothing they couldn t handle. Anthony and Gus came the next day worked their butts off and I have my central air conditioning working right after 11 years. Great price and did over and above what was told to me in the beginning. I would recommend them to everyone and give them a 5 *****. We are very Happy People now. 👍👍😊😊"

"Mo is honestly a breath of fresh air. The quality of his work is second to none. He is brilliant. He works to find solutions. He does not sell you on anything but, instead, gives you options to make decisions. Mo is a wonderfully kind man. He is trustworthy with excellent communication. He always arrives on time. I could go on and on, but he really is a gem of a find. I highly recommend his company and would use him for anything HVAC related."
