Recommended Customer Reviews

Patrick from Anaheim was on-site during the scheduled window, and promptly tackled our gas heater issue. Extraordinary service -- friendly, took time to answer all questions, never rushed us or the work. Incredible service, completely satisfied! Thank you!

NexGen WILL rip you off. I used NexGen for two issues a water heater was not able to heat the appartment building and separately one shower unit was not getting any hot water. The NexGen tech Larry seemed pleasant and convinced me to spend $1800 to replace piping in the shower area and replace a pump on the water heater for $3500. After paying him the hot water was still not working. He called to tell me the only way to resolve the issue was to replace the entire hot water system at a cost of $16,000!!!!! After two months and several calls to the company to send someone to repair the issue, they never returned to resolve the issues. I eventually paid another company who was able to resolve the issue immediately and for a tenth of the cost! DO NOT not trust NexGen!! They are con men.

Clemente and Rigo came out tonight to cable my main sewer line. They were communicative, polite, and informative. They took care of the problem quickly and then followed up to give me their take on the situation. I didn't feel like they were upselling at all. Rather, they were doing their best to make me informed of the situation. Thanks so much to them and NexGen.

After soliciting a few bids from contractors to replace my old furnace, I ended up choosing NexGen. I chose them not because they had the lowest quote (they didn't, but they were close), but because they seemed the most organized and polished. I was not disappointed. The installers showed up on time (in fact, a bit early), and they proceeded to take out my old furnace, clean up and seal the space around it, and install the new one. Throughout, they made the process seamless and almost invisible to me. When there were issues, they figured them out without burdening me. At one point it turned out that the exposed part of my duct work was leaking, and it wasn't in the contract for them to fix it, but they replaced it with brand new stuff at no cost or inconvenience to me. That's the kind of high caliber outfit this is. The most impressive part is how polished and professional the job looked at the end. Everything is just so clean. And the furnace works perfectly.
After talking to several HVAC contractors in the LA area, here's my take. Nexgen aren't necessarily the cheapest, but they charge a more than fair price for the job done right. Other contractors seem like they cut corners here and there, don't guarantee their work as much, or compromise on the quality of the components. Nexgen do the kind of work that you'll never have to worry about, at a more than fair price. They did everything right in my case. I highly recommend them.

Very knowledgable and educates their clients about their equipment. They did our heater and cooling tune up. Highly recommended! Thank you Manny!

Today I had a preventive maintenance service on my HVAC system. The technician Manny was very friendly and professional. He thoroughly checked my systems and gave me recommendations. Manny was not pushy which I appreciated. He cleaned up after he was finished. After my last experience with another company NexGen was refreshing.

These guys have gone DOWN HILL fast. They are no longer reliable, professional, or competitive.
We had some plumbing work done 4 weeks ago and have been struggling waiting for the project to be completed.
I have sent Kenny Domino, their ""controller"" multiple emails but he is not responsive.
Avoid these guys if at all possible.

My technician Manny came out to service my HVAC package unit. He was very professional from when he walked in to giving me detailed information on what the issues were with my system. I will always call him for all my services.

I called Nexgen for an estimate to replace a leaking Asbestos/Transite furnace flue. They responded promptly and provided a competitive estimate which I approved. When the contract was prepared though, I noticed they planned to use single wall pipe, and there were special instructions saying a new roof cap 'should be installed'. When I asked, the estimator said the install team would decide whether it was necessary to replace the old (leaking) roof cap.
The crew showed up late for their install window, and sat in their truck for another 40 minutes before approaching the house...then knocked on the door requesting to take a photo. Shortly after, the Nexgen estimator called me, requesting an additional $600 above the contract amount, claiming the flue went through a soffit he hadn't noticed. Having done some construction, I politely informed him that I was looking at the roof and the pipe did not go through a soffit. But the estimator said he couldn't disagree with his people onsite. I refused to pay and Nexgen left.
Yesterday, I had the work done using another company, including proper disposal of the Transite pipe with an abatement company, and installation of a double-walled flue with new vent cap. The repair confirmed the vent went straight through the roof - not through a soffit. And the total cost was 40% less than Nexgen requested.

too expensive and they don't do much as far as their preventative maintenance and/or diagnostics.
