Recommended Customer Reviews

My mother in law has been feeling ill and staying with us. As an 80+ year old, she is cold often, and unfortunately, our heater broke in the middle of one of the coldest months of the year. NextGen provided incredible service, replaced our heater quickly, and offered a great price. I wanted to make sure I highlighted their wonderful company. Thank you for giving us one less thing to worry about this holiday season!

NexGen was one of several companies I had come to my house. Each company was helpful and informative but none of them looked at the big picture for me. It was not until NexGen that their employee Mario explained pros and cons of replacing a heating system with full duct replacement. My set up was old and in bad shape and while the other companies did give similar prices and basic run downs, Mario explained short term and long term benefits that catered to my specific situation. They also gave me a great 18 month interest free payment option and were able to start on Monday after an appointment Friday evening. I appreciate the confidence and full scope breakdown. That's what I like in my projects give me all the good the bad the why and why nots. Let me make an assessment from there. Thank you and I look forward to my new Electric Heating and AC system!

Kevin and Steven are everything you want in service technicians! They were always on time, great communicators and solution based...always keeping the costs fair! I've used NexGen for plumbing, heating and air for years. I highly recommend!!

Outstanding customer service! We recently called in another HVAC company (ACE Mechanical) to inspect and clear out our primary condensation line and they supposedly addressed the issue. However the issue was never fixed as we noticed condensation continuing to pour out of our second line. On top of that the techs were a bit arrogant and did a half ass assessment. Out of frustration we called NexGen and thankfully they were able to save the day. Eddie R. from NexGen is a class act - very polite and knowledgeable. He was able to come in to reassess and truly fix the issue. NexGen has earned our business for life.

In giving Nexgen 5 stars because of Omar. That young man is very knowledgeable of the equipment. His customer service skills are excellent. Any future services that I would/might need on my system I would be asking directly for Omar. He has become my A/C guy .

I've used NexGen several times for my Heating/AC and they've always been great. A few weeks ago they were here for an inspection and casually mentioned that they also do plumbing. I didn't know that and said I'd keep it in mind. Well, the very next day, I noticed one of my drains was backing up, so I called NexGen. It turned out that our house needed major repairs. Ramon and Andres from NexGen were super helpful and patient throughout the long process of getting everything working again, spending hours in the house, in the yard, and under the house (which is difficult for anyone bigger than a child!). I'm so grateful to Andres and Ramon, and to NexGen, for preventing a plumbing catastrophe that was about to happen.

Good evening I'm a new customer and i had to come here and express how amazing my service was. Roger and Jose were great, very empathetic to our situation with our heater. Very informative and had no problem answering questions for us. I was so sold that i signed up for their membership. Highly recommend them . Thank you Roger and Jose.

Roger was prompt, courteous, and had his Covid protocol in check; our old forced air system in our condo did not worry him as his job was to help us solve the problem. His honest attitude and friendly demeanor are worth every star!

At my business my AC stopped cooling. I called and they got me an appointment the next morning. Patrick was on time and very friendly he cleaned out the units and was quick and price was reasonable. After a few days I noticed it was still having some issues. Patrick came right out diagnosed the issue quickly sadly the parts did take a few days to arrive and that was a little hot to handle but we kept our cool until the day arrived to fix. Patrick was already on site and working before I even arrived and had it working quickly. He was able to save me some money and yesterday some of my staff had to put on a sweater I had it so cool in there but we ain't complaining it's lovely. Thanks again Patrick for your work

Ruben came out late in the evening to help fix a mini split AC unit that smelled of socks. In about twenty minutes he identified the problem, explained how he could best treat it chemically, have me excellent advice about further maintenance and got the system working excellently. He was also funny, cheer and informative, and left me with insights on the limitations of the system that had come with my house. An excellent technician and service, indeed.
