In a few words, AC Masters LI Inc. is very professional, provide excellent customer service, and 5 star quality of work. from beginning to end Leo from AC Masters provided great service. For my property, this company beats any local competitors and the quality of work and customer service Leo and his team provide is great. Leo installed 5 mini split air conditioner/heater in my house, he was on time, very clean at every spot they were in my house and completed all work in 1 day. I will recommend AC Masters to anyone needing AC installed in a heart beat. Another great thing I liked when working with Leo is that he will explain everything from beginning to end including the design and location of all units and will accommodate any changes requested as long it doesn't affect performance of the units of course. I had several quotes before I decided to go with this company and not 1 can compare to the quality of service Leo provides. read more

On a Friday my central A/C stopped working. Inside temperatures reached 93 degrees. As my family complained I called several HVAC companies. Leo from AC Master was the only owner to pick up the phone. I explained my problem and, even though he had a busy schedule on Saturday, he met me at my house early Saturday morning to diagnose the problem. He explained my options which matched with online A/C discussions. He scheduled and installed my new A/C system that Monday. He and his crew were prompt, courteous, professional, and treated my home as if it was their own. And no one even came close to his pricing! There were no negatives in the experience. It doesn't get better than Leo! I've worked as a contractor for many years and he has my highest recommendation! You will not be disappointed! read more

If you are looking for a top rated AC company look no further. We contacted Leo, the owner of AC Masters, after seeing the reviews on Yelp and we were not disappointed. Leo explained everything, his price was very fair and during a heatwave he replaced my mothers ac system promptly because she was elderly. Leo and his team were so professional, courteous, and very clean and neat. The installation to replace the outside and inside unit were done in six hours including the duct work and refrigeration lines and adding two new registers that he felt were necessary. We highly recommend them for installation or service. It's so refreshing to know there are still honest businessmen out there and Leo is one of them. Angelo and Terry read more

In March, I got Leo and his team to put in central AC and ductless spilt level units in my house. I didn't want to post anything until I was certain everything worked and worked well. I knew after the consultation that AC Masters was the right choice. Leo talked me out of another unit saying two would be more than enough and was he right! His price was thousands of dollars cheaper than the other companies I had come in. On the day of installation, I was blown away. His team was professional, efficient and clean. After all was installed, Leo took his time to explain everything to me. Again, I can't thank Leo and his team enough! They are top notch. Thank you again, AC Masters! read more

We had a great experience with this company, particularly Leo. Our AC unit died toward the end of June and of course because it is summer, the estimates we received from other companies were so inflated. But AC Masters was on point with our budget (not a greedy company) without trying to sell us what we don't need (Universal AC and Heating). We were deciding over our particular situation but when we were ready, Leo was able to install just a couple of days after, not after a couple of weeks like the others. The crew came as promised, installed and done. Highly recommended company and we would definitely call them again. Thank you for your patience with us! read more

My air conditioner went out yesterday with heat wave we are having. Through a friends recommendation I called Ac Master LI. They were friendly over the phone and were able to fit me into their busy schedule. Leo arrived on time and was very friendly and courteous. He checked out my system and didn't mind that I was with him asking him questions. He educated me on my system and gave me options on repairing it on the spot. I could tell Leo was very knowledgeable and loved his job. He was able to get my system back up and running quickly for a fair price. I will definitely use them again and recommend them to all of my family and friends. read more

Leo and his crew were the best price option among the 5 quotes we received. Him and his crew showed up at 8:30am on a Saturday morning, laid down fabric and quickly went to work.

From the first phone call, to the final installation, this company is the most professional, prompt, reliable and honest that I have ever worked with. Leo and his team are absolutely amazing! They contacted me immediately and within a day and a half, I had a brand new central AC unit installed. The price was extremely fair!

They are not only very good at their jobs, they care about their customers. read more

I could not have been more pleased with AC Masters. They were knowledgeable, professional, neat, efficient and honest. I had two AC units installed today. There was a team of 6 guys who covered my furniture and counters in plastic to minimize mess, masterly installed the units, removed a small bush to make way for the compressor and cleaned up in few hours. When it came time to pay, I mistakenly made the check out for too much money. The owner brought it to my attention and asked me to write a check for a lesser amount! I was nothing but impressed! I would use again in a heartbeat! read more

Our central air had lived its life out. We contacted T.F. O'Brien, who we've been doing business with for probably 20 years. Tom O'Brien came over, and explained our options, and we opted for a new Carrier model. John and his crew of installers did a fantastic job of removing the old system, and installing the new system. They were professional and knowledgeable; very friendly and extremely neat. And, when they were all finished, John walked me through the entire job, and answered all of my questions. I couldn't be happier. read more

Leo and his crew were awesome. They came to my house within two hours of my initial phone call. As my unit is not that old, they said it should still be under warranty, and they were right.

I highly recommend them to anyone who needs HVAC work done. They are the best! read more

I'd like to recommend AC Master of Long Island for all your home Air Conditioner needs. My 18-year old Central Air unit broke down during a September heat wave.

So I got speedy, friendly service at a great price. Thank you, Leo and crew; you're the best in the biz. read more
