3 Best HVAC Services in Fontana, CA

quick response by Steve's 5 start, they understood the urgency and sent Kevin Torres , excellent technician. He explained details what he was going to do and bringing up to code for replacement of water heater. He did the work fast and clean. i will be requesting for an estimate on their service for AC/Heater replacement because i feel if the level of work Kevin did replacing our water heater, i trust their AC/heater service will be just the same; excellent .

New water heater install: Fats, professional and a good price. Andrew explained everything very well, got the job done in a timely manner and made sure to answer any questions I had. 10/10 would recommend. Had my furnace tuned up by Chris as well now, on 11/15/2024, again a great technician. He even installed my new thermostat and programmed it for me, once again great service.

The warrant work on my heat pump was completed promptly. The repairman, Steve, was able to determine the problem quickly and order the parts. He returned today to install them. Steve is knowledgeable, professional, and pleasant. Everything is working like new. I’m a happy customer.

I had Joshua from NextGen come out today for an HVAC tune up and I have to say he exceeded every expectation. He was punctual, extremely professional, and took his time walking me through my entire system — explaining how everything works and what I need to do to make it last longer. He didn't just show up and do the job — he educated me and gave me options without any pressure. If you're looking for someone you can trust to be honest, thorough, and respectful of your time and home — ask for Joshua. You will not be disappointed.

Patrick from NexGen HVAC was excellent. He was prompt, professional, knowledgeable, and a great communicator throughout the entire visit. He took the time to walk through the issues with our system, clearly explain the potential solutions, and answer all of our questions. He was also very personable and easy to talk to, which made the whole process much more comfortable. We’ve been using NexGen for years, and they have consistently provided top-notch service. It’s always reassuring to work with a company that sends technicians like Patrick who are both highly skilled and genuinely customer-focused. Highly recommend.

NexGen, the original installer of my HVAC system, visited my home to provide a second repair opinion. Their technician, Leon, conducted a comprehensive review of both the AC and heater. He was very polite and professional!! Despite my HVAC system being several years old, NexGen treated today’s service as if it were a new installation.
