"Frank Green provided me an estimate for the installation of a mini-split single unit at my parentâ s home in Farmingdale. His two employees did a professional job. My parents are seniors who live with a full-time aide. They were respectful and accommodating. A day or two after the unit was installed, I reached out to Frank with questions on how to operate the unit and possibly moving it several feet. That same day, he had his employee return to my parentâ s home to discuss the matter further and to drop off another manual considered to be more user friendly which solved our issue. I would definitely recommend Just Chillinâ to other consumers."

"Joe was courteous and accurate during all steps of the process from estimating the project including the 2 lbs of additional coolant needed to raise pressure in my HVAC and all other work including fixing hard to reach attic ducts, achieving the estimated cost exactly. He was also a pleasure to speak with and I felt safety was done right at all steps for himself and myself the home owner."

"Mr Chortani is a real professional. He is reliable, honest and knows what he is doing. I spent two days with him while he replaced my boiler. He thinks first then does what must be done without making any mistakes. He does not waste time or material. He did exactly what he told me he would do. All contractors should be like Mr Chortani. If you need "The Best" go with Chortani Services HVAC. Thank you Mr Chortani!"

"James Stone was really good. We had a little confusion about the rebate for the original furnace they were going to install but we came to an agreement and I received half of the rebate due to me not being qualified for the full rebate. I was more than satisfied and they were very accommodating. Everything is working great. He went out of his way to make me satisfied. Thank you for giving me this company's information."
