Recommended Customer Reviews
Benny came out to service our 1.5 year old unit, he was on time, knowledgeable and efficient.
My tub was leaking thru the first floor ceiling. AARON arrived the next day as scheduled. He is polite, he respects the safety and cleanliness of the job area. Explained the issue, provided me the opportunity to see it, and also showed how moisture was tested. He came back for the repairs as scheduled. He communicated when he was to take a lunch and return. His work ethic is great!! That helps to provide confidence in the company.. Great Job to Aaron!! I like the company
Lydia Y.Mr. Kevin Richardson is the best of best!! Very nice and patient, did a great job to clean our kitchen drain, also fixed the leaking pipe for us. I will definitely recommend this company and use their service especially Mr. Kevin next time!
David responded and took care of our clog with no issues. David was very professional and answered any questions I had. David even gave me a quote for another service without aggressive sales tactics. I will highly recommend NexGen to any one in need.
Even though I had my air conditioner serviced in the spring, come July it wasn't working. NexGen came out quickly and found the wiring issue in my breaker box that caused the problem. AC was back on by that evening and got the information needed to get the electrician out to solve the problem.
They redid all of my plumbing and put in a tankless water heater and water purifier. Victor and Miguel and their crew did a Wonderful Job! They were Awesome! Jesus came to do the extra electrical. He did an Amazing Job also! I would highly recommend them! Thank you! We really appreciate all you did!
It's been about 7 months since I got my system installed and I had such a great experience with David Moreno and Jonathan Demas that this review is past due. I had an old system that kept giving me trouble every year I knew I would need a new system soon. Jonathan came educated me and honestly I didn't feel pressure to buy one but I leaned alot. David came gave me a quote on different options. After comparing different companies I decided that Nextgen would be the best for me. Both gentleman very kind and professional. When Jonathan and nextgen came the first time and to install the system they were very productive and professional. Used shoe cover before entering and cleaned up after themselves. I highly recommend Nextgen.
I hired them to fix gas leaks in a condo in Ontario. They did detect the leak and did the fix. However, they charged $1,800 which is too high. I should have hired a general plumber/handyman and saved some $$$.
Cathy ..I called Nexgen for a quote and my technician Jessie was extremely knowledgeable with the services and different products. He answered all my questions thoroughly. Excellent customer service. Came in with shoe bottles without even me offering a pair. I would 100% recommend Nexgen but more particularly Jessie. Will definitely use them for all my plumbing if needed.
I had a new HVAC system installed this week and was very pleased with the crew who came out. So far, everything has been working great and I love the new thermostat!
