Recommended Customer Reviews

I got my new A.C installed for the summer a week ago and everything was going great for the first 5 days until it took a crap rite when summer is getting started. I called to see if anyone can service it and I was told the next available day for someone to come in would be 4 days later. This is one thing I didn't like at all. Everything besides that was good now if this is the begging what can happen a month from now

Danny came out to give us a 2nd opinion on our air conditioner. He was very professional, easy to talk to, explained everything he was doing, and HONEST! Another company told us we needed to buy a complete new HVAC system for $21,000. Danny diagnosed a few problems and fixed them while he was here, saving us thousands of dollars!
Call NexGen HVAC & Plumbing when you have any issues with your system or just need a tune up. HIGHLY RECOMMEND Danny!

Our AC unit wasn't kicking on and my husband called in to have a technician come out and check the unit. Noah was very responsive to our call and vel in with his expertise and found the issue and resolved it! Noah explained the issue and fixed it! He was very polite and courteous. Thank you Noah and NexGen for keeping us cool before the heat starts this summer!

Noah came to perform an ac only maintenance for me and man this kid is amazing. Tells me everything going on with my unit I highly recommend using him for any ac or heat needs to be!!

Our AC hasn't been working for the last 7 years. Called NexGen and the day after Noah and Marcus came. Noah was extremely professional and friendly. He explained everything thoroughly to us as far as what was wrong and outdated with our system. Marcus explained our options for a new system and we definitely look forward to hopefully enjoying a cooler summer this year! Thanks Noah!!!

I got my AC unit at NexGen last year. Aside from the Financing side, EVERYONE has been professional. The people who installed were very friendly and NexGen did a complimentary inspection and maintenance.
Noah F., the technician was very Helpful and Professional. When Noah arrived, he told me what kind of maintenance he was going to do. When there was something that needed to be done, but the parts was not in his van, Noah went back to the office and came back to install the part.
Thank You For Explaining and Your Professionalism.

We had Raymond and Noah both out on site to take a look at our water heater and HVAC system. Both of them were thorough and were very easy to work with! I would highly recommend NexGen to anyone in the IE looking for an HVAC or water heater tune up!

I may update this review later because I requested two jobs from them. One of the jobs was an ac cleanup after martin explained the benefits of it. He was very kind and helpful and OMG did my system need it. He washed PAINT out of my turbine. Apparently when I had some painters out a few years back they got it all up in my ducts. I would never have known if it weren't for Martin and he explained every step of the process and what some things I never would have noticed meant about the health of my ac system. Would recommend.
