We are a family owned and operated business with several years of HVAC experience. We pride ourselves on providing an honest and accurate quote and stand behind our work. We have outstanding ratings and provide superior customer service. Feel free to check us out and give us a call for more information.

"We had a very smooth and positive experience with Mazgan Air Conditioning & Heating Repair when they replaced our old Burnham IN8NI boiler with a new model. From the first call all the way through installation, they were thorough, professional, and extremely easy to work with. Their communication stood out right away — they were clear, responsive, and always willing to explain what they were doing and why. Every question we asked was answered in detail, which gave us a lot of confidence throughout the process. The technicians were on time, respectful, and kept everything clean while they worked. They were able to schedule the job within a few days and completed the entire installation in a single day, which was impressive. Pricing was competitive, and they even offered financing options. Overall, we highly recommend Mazgan to anyone looking for reliable, honest, and skilled heating and cooling professionals. They were truly great to work with."

All Weather Heating & Cooling has been serving Nassau & Suffolk County of Long Island since 1969. We are now celebrating 56 years of exceeding customer expectations. All Weather provides sales, installation, service and maintenance of residential and commercial heating, air conditioning & water filtration systems.

"They installed a minisplit cooling system, with 3 exchanges June 2021. Since then it is not operating the way it should. In my bedroom with the door closed at night on cool at 70 degrees the humidity goes up to 80%. I wake up uncomfortable, change it from cool to dry mode. The humidity will go down into the 50% range but the temperature drops down to 62 or less! So in cool or dry mode I can't get a good nights sleep! They come and look at it and tell me everything is fine. I'm going to buy a window air conditioner tomorrow which seems insane because i spent $10,000 on this minisplit AC system!"
