  • We had our maintenance done on our furnace and AC today. David was our service technician and he was very thorough and spent the time explaining what was done to assure us our furnace and AC would work when we needed them to. We were very pleased with his work.

    Matthew Marks

    Highly professional, friendly and affordable service. I had a cooling & heating system installed at my art school a couple of weeks ago and I am so pleased to have chosen Air Options. Amazing service from first contact to install. Very knowledgeable staff where always fast to respond, incredibly helpful and went out of their way to meet my needs. Fairly priced & provided a smart, very quiet and effective system which perfectly fitted what I was after. The system is energy efficient, has inbuilt nano technology air cleaning system which is reassuring in these times & came with an easy to operate control panel. Delightful company, thanks Edgar & David !

    This was the best service I have ever had for my annual Mini split check -first time using 24/7 HVAC of Long Island and have had service from a few different companies for the past 27 years. David was the technician and he was very thorough and efficient. He explained lots of things to me that nobody else over the years has ever taken the time to do - very polite and attentive. I was very impressed and am now sure of which company I will deal with from now on. Thank you 24/7 HVAC of Long Island.

    I called 24/7 HVAC of Long Island in the evening and Matthew came 15-20 mins after. He was able to diagnose the issue within 15 mins and provide a fix for us. Thanks to him for a great service.

  • Extremely happy with our new unit, although it may be a little time before using it to its full potential, it does look very high tech. The technicians Matthew and David were extremely professional, polite and caring the office team kept us totally up to date and informed. Great service thank you.

    I called this business on 6/2 to inquire about central air installation and David gave me an appt the very same day. I had it installed today 6/4, and the technicians literally just completed the job, from start to finish it was about 12 hours, which was longer than I anticipated, because my set up was a bit complicated, but they got the job done. The 2 technicians was professional, knowledgeable, and their work was done neatly. Customer Service is really A1 which makes all the difference.

    Great service from 247 HVAC of Long Island. Their prices were very competitive with other local installers. We received a quote with 3 options for a single air conditioning unit and decided on the middle priced one. The engineer was on time, polite and carried out a very neat and tidy installation. Afterwards we were given a run through of the modes etc. Couldnt wish for a better service

  • New furnace installed!! The installation crew arrived on time and were polite and very neat in their work. They explained the new system and it's features so I was comfortable with the new product.

    Joey Williams

    I just want to give a big shout out for the outstanding work that was done by 247 HVAC OF LONG ISLAND. They came within an hour of the initial call, diagnosed the problem quickly, ordered a new motor for our furnace then installed it as soon as it came to their office. They didn't try to upsell us on a new unit like other HVAC companies. They were very professional from David courtesy all the way to our Tech (Edgar). I would highly recommend them and the best part was their prices were extremely fair. Great job!!!

  • I've been using 24/7 HVAC for years and I think they are the best AC repair Company around. I love that they are open 24 hours and that they provide great customer service. Their technicians are so knowledgeable and I love that they always fix the problem and don't try to sell you more than what you need. They are also affordable and their technicians are friendly.

    Easy to schedule an appointment, arrive on time, clean, proffessional, friendly. Explained everything and got the humidifier to work again also. Installed AC in my living room. I love having a maintenance plan so I can catch things before the weather hits.

    Anthony P. O'Connor

    David was recommended to me by my realtor and I am a 110% satisfied customer. As a new home owner, I knew I needed professionals I can trust and Engel and the team have been great. Thorough, professional, and good communication. Will be using them for all my HVAC needs and recommending them to all my friends.

    Great experience! They were responsive and helped get my furnace installed quickly and at a reasonable price. I used them after having a very bad experience with another company so their professionalism and efficiency was really appreciated. Would recommend!

  • Luis is professional, knowledgeable, informative. He really seemed to care about providing us with the best service and information. At first Luis checked our heat pump. Then he suggested we had a leak in our heat pump and that it could not be fixed and so he told to install a new one. Our heat pump was too old that's why we also agreed with him. Luis installed it very efficiently. No mess, clean work. Thank you Luis!
