    Thank You JetAirCo

    I am so grateful to Jon at JetAirco and his excellent well trained professional workers. I had a complete disaster at my house and spent alot of money on another plumber. Jon and his team came in, immediately saw the problem, explained to my wife and I why there was a problem and how he would fix it.  I let Jon and his team do their thing and I was back up again with heat, air conditioning, a plumbing that is done right. He really showed his empathy after hearing our story of getting milked by another company.I highly recommend Jon and JetAirco

    • 5 star review  I had the Jet guys (Mark, James and Addie) at my home once again today. This time the piping to my boiler sprung a leak. The first time they fixed burst heating pipes in my slab foundation. Again they were professional, courteous and prompt. As usual their work was outstanding. This is our second encounter and it is a pleasure working with them. Their pricing has been fair and reasonable. Jon thanks again for having such a great crew to work with.

    • 5 star review  I know nothing about ac and heating and John was willing to come and teach me so much. I spoke to a few different companies and his answers made most sense. Honest and trustworthy feeling from the beginning. The guys that did the install were professional and caring about the job and not just trying to get it done with. Truly enjoyed working with this company. The ac works great. Such a caring company. Won’t leave you hanging.

    • 5 star review  Compared to other companies (and I just called at least 6 of them right before this one) they deserve 10 stars. I spoke with Jonathan over the phone, on a Saturday, because I was having heating issues. In my situation he knew exactly what he was talking about, and was not only knowledgeable but compassionate. He didn't want me to go without heat over the weekend but also did not want me to pay overtime prices if he could help it. He literally spoke with me and helped me troubleshoot over the phone on a Saturday! Now that I know I can trust and rely on him, I know exactly who to call to service my heating/cooling system as a new homeowner.

    • 5 star review  Jet Air Co is a reliable, family owned and operated business providing excellent heating and air conditioning services. Jon DiMaio and his team make every service call a priority, and work extra hard to make the inconvenience of having a daily need disrupted bearable, and fixed as quickly as possible. We have an annual contract for all our needs with Jet Air Co, and Jon DiMaio’s recommendation of installing a mini a/c & heating unit has made Makenzie Cadmus significantly more comfortable in our home. For all your heating and air conditioning needs, you can’t beat Jet Air Co!

    • 5 star review  Woke up to a cold house (62 degrees), the boiler stopped working. I phoned the company, and they moved around some appointments to accommodate me. The technician Kyle, arrived promptly, he was professional, courteous and he knew his boilers. He diagnosed it immediately, needed a new thermal coupling, he replaced it and we were back in business. The price was reasonable and fair. I would def recommend this company, Kyle was knowledgeable and professional hard to find good service people. Great job!

    • 5 star review  When PSEG came to “fix” something, they ended up shorting out our Central AC unit. It was almost 5:00, my wife and I were away on vacation and saw the alert on our App that our house temp was climbing, and our two young children were stuck in our hot house with our babysitter. I called JET Air, explained the situation, and two repair technicians arrived within 30 minutes. Not only did they work quickly (in our 100+ degree attic) to repair the motherboard and get the AC back on, but they kept us in the loop the whole time so we could stay informed while we were away. Our house was nice and cool shortly thereafter, and the technicians showed up first thing the next morning just to check on our system and ensure everything was working properly. JET Air installed our new system two years ago, and they have been our go-to guys for maintenance and repairs. Professional, responsive, courteous, and understanding, these guys are the best.
