Recommended Customer Reviews

Can't say enough about the team of Adrian & Josh from NexGen! Scheduled them to come out to service our HVAC & Tankless Water heater! These guys were on time, professional & super friendly! Took their time to be sure that our respective units were working at top efficiency and gave us some helpful insights. We own a building and design company and were very impressed with their skill set and knowledge. Don't hesitate to call them out for your next service call. You will be so pleased. We highly recommend them!

Extremely organized operation and our technician, Patrick, was prompt and professional to evaluate the problem with our AC. Unfortunately the the quote for total replacement came in really high for us to move forward. If this was our forever home, we'd have a different perspective- especially backed by a great warranty. But, we ended up going with a more economical solution. But you're in great shape if Patrick knocks on your door!

Patrick Cordova came out from NexGen. Very professional and helpful. He answered all my questions patiently with details. I don't know anything about the AC but he explained each and everything that he checked with details. Thank you Patrick.

The excellent service with NexGen continues!!! We've been customers for many years and had our entire heating cooling system installed by them - kept the yearly Maintenace service up as well. From the time I contacted NexGen for my most current service request, I was always kept apprised of the assigned tech's work status at his prior commitment. Adam arrived at the time he approximated, and trouble shot the errant condition of my issue thoroughly investigating all probable areas of the condition. Quick fix and assurance that the fix held (minor short) by (re)running the system and checking the fuse. Very professional and knowledgeable with great communication skills. Five Stars to Adam and NexGen.

Juan and Damien have done an exceptional job while here! It was so easy to schedule an appointment through NexGen and both were timely, with text message updates for my appointments. I called NexGen due to an issue with my condensate drain line. The secondary line from my HVAC was dumping water onto the floor of my garage and the primary line was completely clogged. I had a company come out previously through my home warranty, who temporarily fixed the issue I was having, but left my drain system far from being up to code, and mickey moused together. When Juan came out, he pointed out everything that was done previously that wasn't up to code, took pictures of what needed replacing, and showed me what my options were and the cost associated with each option. He explained everything thoroughly and made recommendations as well. Damien was also extremely helpful. He walked me through the process of doing the water heater flush (which I had added on as part of a promo NexGen was having) and made me aware of a few safety concerns, which are now resolved! Everything is now up to code and looking far better than when they first got here. Both gentlemen were kind, respectful, and thorough in their work. Will definitely recommend!

Adrian did a great job repairing our system and setting us up with a very reasonably priced cleaning plan to prevent this issue from coming up again. Especially compared to our previous HVAC company, we've been impressed by the friendliness, responsiveness, and professionalism of NextGen.

Had an issue with my rental property AC unit dripping water. Patrick came out to assess and troubleshoot. He was very communicative from the start, arriving promptly at the tenants residence and kept me in the loop upon assessing the issue. Upon learning that i served in the military, Patrick was kind enough to give me a $100 Veterans discount. Haven't heard anything negative from the tenant regarding the leak, so fingers crossed! Would use Nexgen again

I called NexGen for HVAC service. They had availability the very next day and offered a one-hour appointment window, which is unusual and very customer-friendly. The technician, Justin, was on time, friendly, and very professional. This company has an excellent team.

We needed someone to look at our a/c unit and Justin from Nextgen came right out the next day. He was on time and provided us with a thoughtful explanation of the issue, explaining everything to us and breaking things down in layman's terms that were easy for us to understand.
We have an old unit and Justin took the time to explain all the pros and cons of fixing versus replacement so that we could make the best decision for us.
I definitely recommend Nextgen, especially as long as they have employees like Iustin

I seldom write reviews however I have to commend Justin for his promptness, advice and help. Learned of a water leak and uncertain of where was coming from. I called and same day arrived to check our units. He provided detailed information and an efficient game plan. Kudos to your team.
Thank you Justin
