"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."

"I highly recommend Absolute Zero. Kyle didnâ t try to sell me upgraded equipment, he sold me what works sufficiently and what he would install in his house. I got a few quotes for the central AC and his price was the lowest. Installed in the attic that will be renovated into a room, he worked with me and planned and installed the air handler unit and all the ductwork where heâ d leave the center of the room open and did a great, clean job. He said the AHU upstairs and condenser unit outside would be quiet, I was shocked at how quiet everything was. He protected furniture and floors while they worked and left the house clean and tidy after leaving. Iâ m extremely pleased with the work and have already referred him to others."

"I talked to several AC companies before selecting this company. These guys did a very professional job and also gave me a very competitive price. I highly recommend them. Trust is everything and my gut was right when I selected them."

From dust, dirt and dander to debris and allergens, any number of potentially harmful particles can get trapped inside your duct system. A dirty duct system will continue to re-circulate this contaminated air and, in some cases, it can escape the system and be distributed inside your home. In other cases, it can stay in your ducts and continue to attract even more dust, increasing the amount of contamination day after day.\n

"We have been struggling with the heating system of our brownstone for the past 20 years and had our fair share of HVAC professionals trying to help us. It was not until Chortani Services showed up that our heating problem was solved for good. They are incredibly responsive, very experienced and trustworthy. Thank you!"

"Joe was very respectful, personable and patient and explained what he would do and why to ensure our central air would finally work. It took ALL DAY but he installed an exhaust fan in the ceiling with attic ducts to draw out hot air, performed a chemical wash of the condenser, installed a wifi thermostat that required a new transformer and taught me how to use it. I LOVE being able to monitor indoor and outdoor temps on the app and I can see that our summer tenants are using it and that the AC is working great when needed."

"They were fabulous, courteous, prompt, on time, and did excellent work. They even had the best price and the value was outstanding. They are a family owned business and I would highly recommend them. I am going to get a maintenance agreement with them in the future."

"I sent a message to the company in the late evening regarding my broken central AC and Jason was here Tuesday morning to look at it. He tried to repair it but was not able to due to the age of the unit and the damage. We needed a new unit and he was here to put it in first thing Wednesday morning. Took him two hours and our AC was working. He was nice and professional. We felt the price was reasonable. Would use him again and recommend his business."
