On 6/4 I had work done by John and his great crew. They were punctual, explained the process from beginning to end and even cleaned areas when the job was completed. After everything was installed, John came and gave a thorough explanation on settings and etc. Great service And professionalism.

This company is the best in Long Island and Queens. John and his team came and install 4 units and help me close my 2 window AC holes. Prices are the best too.

We recently had our home upgraded with several split units installed by Long Island Air and the experience was excellent from start to finish. The team was timely, professional, and extremely responsive throughout the entire process. They answered every question quickly and thoroughly, making us feel confident and informed every step of the way. The installations were clean, efficient, and completed with great attention to detail. You can truly tell they care about the quality of their work and customer satisfaction. Highly recommend them to anyone looking for reliable and professional HVAC service on Long Island!

I had some work done by LIACA (4/2026). They really went above and beyond. I had 6 heat pumps installed. The install went smoothly, clean work, no issues, and they listen to you when it comes to where the units will be placed. I really loved the fact that they made it easy for me when it came to completing the forms for the rebates. They are very hands on with the whole process. They kept me updated every step of the way. Their prices are really great too, I did some research and other companies were changing an arm and leg before the rebate was even considered but LIACA prices were the best on the market. The units works perfectly and omg they are quiet. I had a/c units throughout the house and they were noisy. These new units are a complete night and day. I’ve included pictures of the units installed so you can see the finished project. I really and truly appreciate the team and would be recommending them to family and friends. *I will update within the year to let everyone know how my systems is holding up*

John and his team were terrific. The solid communication, the attentive service, and the smooth install were all fantastic. I would recommend LIACA for your air conditioning and related needs. Thanks John Update, one year later John and team helped install a larger 18,000 BTU unit in our east end summer place in Southold, NY. The installer came on time, installed the unit efficiently, and we love our new AC and heating unit. Thanks again John!

My central kicked the bucket. John helped us go through all the options and gave us his recommendation for a new unit at a reasonable price and fair price. Communications was great, our questions were answered quickly and we got to see the different models they offered. On the day of installation John made sure things went smoothly. The guys were quick and efficient with the installation. They hauled away the old unit and installed our new thermostat. I cant recommend LIACA enough they came through during the hottest days of last summer.

John and his LIACA team provided a prompt and comprehensive quote for a Fujitsu inverter heat pump system replacement and upgrade, with options to consider, all at competitive prices. The LIACA team of professionals installed our system on schedule, creatively, neatly, then provided a full system demonstration when complete. We could not be more pleased with LIACA's approach and work, and give LIACA top marks in every category, unequivocally. To the extent we may in the future require HVAC work, LIACA would be our first call.
