"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."

"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!"

"Installers arrived on time and everything went smoothly. Had to have them back a couple of times to balance out the rooms. Some were not cooling properly. After the third time they finally got it right. First technician was a younger guy who was not keen on going into the attic since it was hot up there. He didn't know what he was doing. Second guy the same. Third guy was an older tech that I made a comment about it being hot in the attic and his comment was that this was his job no matter the conditions. Very professional. Should have sent him the first time."
