We use LIHVAC for install & repair of our 14 commercial RTUs and we are very happy with the result. So far, the experience has been positive. Competent and professional.

Long Island HVAC did a great job keeping my old central AC running and then gave me a great deal on a new system. They were very responsive to all my questions and then did the entire system replacement in one day. I am very happy with my new system and the work that was done. I would highly recommend Long Island HVAC.

I really enjoy working with this team! In this instance they were able to replace a system that went down in the middle of the heatwave. They quickly acquired a new unit and had the customer in cool temps in no time. I will always refer them to anyone who asks!

Great Company, on time great to work with would recommend!

Ray is very professional. We are a Home Improvement Company ( A + Quality Designs Home Improvements Inc) that always needs responsible sub contractors to help us maintain our high quality standards and professionalism with our customers. Ray exceeded our expectations and our customers as well!! Thanks Ray!!

Very Pleased! We called for our place of business to fix a commercial AC unit that was leaking. This company was excellent with response time, and communication. When they gave a date and window of time to expect them they promptly arrived. They were professional, got the job done, no issues. They even gave me a follow up message making sure everything went well. They made this very easy, no headaches. I recommend this business!

I was referred to LI HVAC by Jay from Green Team. I am so happy for the reference, They came right away, found the problem and fixed it, They were very professional and kind and also Nicole was so sweet. I am thrilled and will be using them from now on. I had my new air conditioner installed three years ago by Sun Ray Systems, a total nightmare. I had so many problems and even though there is an ten year warranty on the unit, it’s only two years with Sun Ray and I would have get a service contract with them and I won’t. I highly recommend LI HVAC, you won’t be sorry.

Long Island HVAC installed a split system for us. We are very happy, they were very professional and a pleasure to work with, I would definitly recommend them and use them again.
