Recommended Customer Reviews

We were having some issues with our mini splits and had called multiple vendors to come out. After being let down by repair companies not showing up I remembered seeing the owner of the company on the news awhile ago and figured I liked what his company set out to do. Well Edward P. is definitely carrying that legacy for the company of providing reliable and valuable service. Edward arrived early, called me to let me know he was in his way and was very detailed in explaining every step of what he was doing.
I would 100% recommend NexGen and will be using them more in the future!

I usually don't bother writing bad reviews. I'm a 74 year old senior that called them to repair my old central air furnace that was not heating. The technician said that he did not know what kind of furnace it was because the units tag was missing. Also rats had chewed many holes in my duct work which was a lie. He said that I needed the unit replaced. He said he could have a manager give me an estimate. About 1 1/2 hours later his manager shows up and gives me a sales pitch with a LIFE TIME warranty on a new unit for a cost of $23,000.I told him I was going to get other estimates. I called Bryants Heating and Air in Pasadena. They had to rewire my heating unit to test what was wrong because Nexgen tech had disconnected and pulled out all the wires . Bryant's tech determined it was a bad fan limit switch which is a part that cost about $130. NexGen is a sleasy company that can't be trusted. Their ""life time"" is only as good as their reputation and I would never
trust them from my experience. Their tactics are not a company that will be around in the future very long so what good is their ""life time"" warranty.

My mother in laws residence needed a new wall heater. Many hvac companies do not work on these types of heaters. I finally found NexGen. The tech that arrived was German. He was extremely professional and took his time figuring out what was wrong with the heater. I was influenced with his friendliness and professionalism, I decided to contract NexGen to replace the heater. Thank you, German, for all your assistance and knowledge.

I can't comment on their workmanship, but I had NexGen come to my house and I've never dealt with a more pushy sales vibe than with them. Their prices were more than twice, sometimes four times the price of the other estimates. I don't want to leave a review and say they do bad work, that's why I gave them three stars instead of one, but I wanted to leave a review so other people calling them will know what to expect.

Too expensive Thermostat needed to be replaced. Tech replaced with new unit I had on hand. Charge was close to three hundred dollars. Excessive amount charged for work provided. Tech was more concerned about selling other services like a new HVAC system. Tech did identify some issues that can be remedied easily. Tech took a video. He and his buddy had good laugh in the front of my home. Not very professional.

The company response so quick and the technician is cool and nice. Really recommend this one.

I live in a trailer that's 600 square feet. NexGen quoted me over 18,000! When I pointed out the small space he lowered
The price to replace my heating/ac unit to 14k. Beware!! This place overcharges!! Don't go with this place unless u have $$ to burn.

Was needing my AC serviced. Kept seeing the commercials for there $88 dollar special. So I took a chance and gave them a call. And let me tell you I was not disappointed!! Adrian was the tech they sent out. He was so polite and did a Thorough cleaning and explaining every step to me. I highly recommend NexGen for any AC services. You won't be disappointed.

Thank you both again for a great job and great customer service with my tune up!!! Your company is always honest and works with me to get the right price. I have used you for about 6yrs now and will always refer you guys to friends and family!! Thanks again Adam and Ruben make sure he's available next service in April.

Our A/C wasn't working well, putting out hot air. I saw the commercial for the company on TV and decided to give them a call. What a mess. They came out and said we needed a new system. Also, gave me various options and quotes which he sent to my email same day all over over thousands of dollars (7K). My wife and I thought we were on a car lot and he was selling us a car. Ending up spending over $600 for a cleaning and a new capacitor. Nothing changed. I then called a friend who knew a trustworthy AC guy. He came out out. In 5 minutes he said my water safety top had come off, it is a safety mechanism for when water does not flow out properly. He ran C02 (air) through it and it works perfectly charged me $75 dollars. I called their supervisor and they apologized and didn't know how there guy could miss it. How many other people that don't know get pulled into their lies and buy a new unneeded system. Do not trust them and do not use them. Go to someone you can trust.
