    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

    • If I could give this company 10 stars I would!! I had a problem with my AC unit. Called their service number within minutes I received a call back from Lauren. She was soo kind and professional. John was at my house shortly after our call to fix my unit. This co. Has a forever customer. If you are in need of an AC co. Look no further they are the best out there. Professional and honest which is hard for find these days!!! Thank you Jet Air co!!!

    • 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.

    • 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!

    • The condensor of my mini split AC unit went bad and was out of warranty...of course this happens when i was 7 months pregnant in the midst of summer. The guys and christine found me a new unit (even though carrier said they were all back-ordered until the end of time). Installed it right when it came in, moved one of my indoor units also for me and everything is working great now. Jet Air has always been just a phone call away since i found them a year or two ago and they always work with you to get you on schedule if you have an emergency.

    • John came to my home and went above and beyond to help me with my condenser. He fixed it within minutes. He was very professional and thorough. John also fixed my humidifier. Everything now is working properly and efficiently! Thank you to John and thank you to Lauren for being so kind on the phone.

    • Replaced A/C, heating pump, and water heater. Had chosen Jet Air Co Inc. after getting amount of quotes from others. I’m not an easy customer, greatly appreciate that Jonathan patiently worked with me, trying to accommodate all my needs. Great prices and products, easy and professional services. Highly recommend. Will use them again.

    • 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.

    • I would recommend JetAir! They squeezed us on last week during a heat wave and there was a bit of confusion/miscommunication, but they were quick and professional in clearing everything up for us. They are finishing the job tomorrow and we are grateful for their kindness and professionalism. They will be our continued HVAC company moving forward.
