Recommended Customer Reviews

From start to finish these guys were great. Answered all my questions added vents and return vents where needed to maximize airflow to keep the house at the desired comfort level all while maximizing energy efficiency. Sean the GM answered or returned phone calls or texts promptly. Had two complete systems put in 3&4 ton AC furnace and everything done in one day. Excellent work done by his crew.

Called the company for a checkup on our system. They responded in a few minutes and provided an appointment the same day. Ruben was very informative and knowledgeable. We were so pleased with his service. He arrived on time and was very nice to answer all of our questions. Great deal for all the checks on the whole unit.

Very friendly technician Informed me of issues with my air conditioner and offered me options to fix the issues. Offered me a service plan that would help save me some money. Will definitely use again!

NexGen will blow and toast every AC/Heating company out there by the way they do business. Impeccable process , very systematic, efficient, fast and reliable installers. We needed new air and heat where they had to move the furnace up in the attic from the first floor. We bought brand new systems so they got rid of the old furnace and condenser. We happen to have had the best team started by John Banks who earned our trust on this company from the beginning when he came to do the 27 pt inspection , followed by John Hansen Paul who took care of explaining the project and financing. The next day came the greatest installation team ever : Roger, Marvin and Arturo. They had 3 other helpers and I wish I wrote their names too because all 6 as a team did an above and beyond job. They came early, had all their materials ready , prepped the house to make sure the floor and furniture are protected from any debris then they started working away. I was blown away by how organized they were. Their trucks are impressive too. The trucks look like this company is out to do some big wonderful things for their clients. Every single worker is very experienced, kudos to the owner Ismael for hiring the best of the best skilled people. You'll just know you are in good hands. This has turned to be a book , sorry, but I can't help but give them compliments. ROGER, you made sure we were happy with your team's work. and we were. Your team is amazing and I do want to thank you all. Ismael, hats off to your company. By the way, they left the house clean. Very clean, professional work. Cost? I can speak from experience... you NEED to go with them.

This is the company for AC service that do the right job! I was buying a new electric AC to replace my 40 yrs old antique... And Corky stop by and help me out get the checkup done and make sure the price is reasonable that for my small place. The installation also done very nice and the installation guys also make sure all wiring and the AC function properly! Man, high recommended if you need to AC job done in IE.

This is a scam masquerading under the guise of a legitimate business.
We spent $68. for a service call for absolutely nothing. They told me at the end of the call what I told them at the beginning.
The quote to replace 2 parts totalling abround $70.00 was $534.00.
The Sears rep from whom I purchased the parts determined the level of install as ""EASY"".
Rip off artists!

We knew our system was on its last legs. We met first with Manny, very helpful, and showed my husband (ex-contractor) exactly what was going on. It was clear it was time to move forward with a new system. Manny again helped coordinate and the installation was completed in a few days with minimal disruption. We can already tell the difference. They forgot a part and while they were waiting for someone to run it out rather than just standing around they went ahead and insulated our utility closet! Really happy with Manny and the rest of the team, and our new system.

My husband got home from work to a very hot house today with our two children. I called Nexgen and they sent out a tech right away. I highly recommend Manny he was excellent!!! Thank you so much Manny!! We'll see you when we get our winter maintenance service.

Our home A/C unit stated blowing out warm air last night about 6 so we called up NEXGEN Air to help out. We've seen their TV commercials and I just recently heard on the radio how they're always working early AND LATE, 7 days a week. My husband spoke to Sean in the ofc and he sent a tech over within 30
min. Their service employee, MANNY, fixed the problem within the next hour, and we were back in cool air IMMEDIATELY! Thank you so much NEXGEN Air-we'll be calling your ofc soon to schedule a full clip on our a/c unit! Great job! You guys Rock!

After my elderly mother was nearly scamboozeled by another company, I called Sean at Nexgen. He was responsive and very professional and saved us thousands of dollars.
He had her new system installed before I could figure out what the other company was trying to sell us with the 5 levels of precious metals!
I think that is enough said. I would definitely recommend Sean at Nexgen again and again.
