HVAC reviews in Riverside, California

BEWARE They not only leave a mess like snack/ food containers in attic, but they also purposely changed maintenance appointments not once nor twice but 3 times on me then tried telling me because I’m passed my “free maintenance” time frame I now need to pay an outrageous amount AGAIN. Nope not happening. The lady on the phone thought it was so funny she just lost a customer. Extremely unprofessional. Maybe contacting the BBB will get them to be a bit more professional.

UPDATE The BBB does NOT accredit this company and out of 9 complaints Nexgen has only closed 2. Clearly this company does not care.

The Tech was extremely knowledgeable, and when I said he did not need to perform a specific task because I handled it, he showed me what I had missed. He really was detailed in performing a regular maintenance check on my mini-spilt. If I need any service NexGen will be my service pro. Excellent job, well done. I rarely leave such glowing reviews, but I was that impressed with the service.

Raymond and Noah came out to inspect and clean my water heater and air conditioning unit, respectively. I was impressed at their promptness, professionalism, and friendly demeanor. Raymond showed me a couple of issues that I was unaware of with my water heater and Noah did a super thorough job inspecting and disassembling my air conditioning unit to give it a proper clean top to bottom. Thanks guys!

called them and they came out right away. diagnosed a leak in our driveway as an irrigation leak that could fix right away. did the paper work and they did the work.........unfortunately that didn't fix the problem, so they came back out and cut a hole in the driveway, still couldn't find it. they suggested we call someone else (!!? that should have been the first red flag) they came back out and spoke to the second company but still didnt fix it....although they stated they would take care of it. Well two months later and many calls later it was fixed, but overcharged use to the tune of 7,200 and although they said they would call back to reprice what was actually done to fix the leak....again many calls and messages later nothing to date. WORST CUSTOMER SERVICE EVER DONT CALL THEM

The service tech that came was helpful however it is apparent that he was trained to upsell. A simple swap out of a water heater was over 3500. This is without the cost of the water heater. That would be over 500 dollars per hour per person. I don't have time that is why I called, I have done this work before and it took 2 of us 2 hours and we are not trained plumbers. Ridiculous costs!

I received such professional, prompt, courteous, and accommodating technicians. Tommy M. and Kevin R. were wonderful. I got a brand-new, state-of-the-art garbage disposal. They were very proficient at what they did and very fast! I’m so happy I found Nexgen. I would highly recommend their services as well as their excellent, competitive pricing. I also left Thai review and a photo on Yelp today. I want everyone to know who to go to: Nexgen!

I was very pleased with Armando who came out representing Nex Gen. He was knowledgeable had great suggestions and most importantly was on time for the appointment. Although there was nothing they could do at this time, I will definitely use next GEN for any plumbing issues that I may have And highly recommend them and Armando.

Jose was the one that came out to inspect my condominium and within 2minites he immediately referred me to a restored company because he saw that the problem was bigger than I thought. He created a report and allowed me to see it , as well as gave me great advice and clarity on what happened.

Our plumber arrived early to install a new kitchen faucet!! Thanks so much, it looks beautiful!

My technician George Guido was very professional, on-time and knowledgeable. He Explained what needed to be done in clear and precise detailed. I couldn't be more impressed with their service, expertise and attention to detail ensured that the problem was fixed efficiently. He went above and beyond to ensure we were satisfied with the work. I highly recommend NexGen HVAC & Plumbing,

A most awesome experience professional and energetic, Michael explained everything included in the service. He took special care to keep our home neat and clean. I would highly recommend Nexgen for any HVAC needs.

Kyle came out and diagnosed the hot water heater problem. He took his time and explained everything, will definitely use in the future.

I had a faucet replaced and a water valve replaced in my kitchen. He took the time to do the job correctly and to my satisfaction. Pleased customer

The technician David Faustino Rojas was very friendly, professional, knowledgeable, and thorough. He took numerous photos and made many helpful recommendations. He explained every step in the process of tuning my AC. I learned a lot about maintaining my unit and how it works. I am a repeat NexGen customer and would highly recommend them for any HVAC or plumbing services.

I can’t express enough how incredibly impressed and thankful I am for Kevin B from NexGen. This guy genuinely went above and beyond—spending a full 12 hours at my house replacing and upgrading my tankless water heater system. From the moment he arrived, Kevin was nothing short of professional, courteous, and thoroughly dedicated to doing the best job possible.

Kevin carefully assessed my old setup, clearly explained every step of what needed to be done, and patiently answered all of my questions with genuine knowledge and care. Throughout the entire process, I noticed his exceptional attention to detail—ensuring everything was installed precisely, safely, and efficiently.

Honestly, it was refreshing and reassuring to have someone so committed to high-quality workmanship and customer satisfaction. Kevin didn’t just meet expectations—he totally exceeded them, setting a whole new standard for service excellence in my book.

If you’re looking for someone who knows their craft inside and out, treats your home with respect, and delivers outstanding results, Kevin B from NexGen is absolutely your guy. He turned what could’ve been a stressful experience into a truly pleasant and reassuring one. Highly recommend!

Brand new $35k two unit heat pumps. 3 years in with two broken condenser drain pans with no explanation why. Also tried to charge me $4000 to replace the part the second time. I highly doubt these systems will last.

NexGen HVAC & Plumbing is very unprofessional. I had a routine maintenance appointment scheduled in June of this year. They ended up calling me the morning of my appointment saying they had to cancel due to lack of technicians. They rescheduled my appointment for July. The morning of my SECOND appointment, same thing, they cancelled due to the technician not being able to make it. I call for the THIRD time to reschedule and I talk to a manager, I forgot his name. But he rescheduled my appointment and assured me I would not get canceled. It is now August, the morning of my appointment, I get no call or text for confirmation or that the technician is on his way. The whole day, no one comes. I call the next day to see why no one showed up, and the woman on the phone said I wasn't even on the schedule. I was on the $14.99 maintenance plan they offer. Every month they charged my $14.99, yet never came. They flopped on all 3 of my appointments. This is the worst service I have ever dealt with when it comes to household maintenance. They took my money every month and offered me nothing but terrible service. Save your money and time and DO NOT CALL NEXGEN.

Shady technicians, inconsiderate service!
Nex Gen has been servicing my HVAC for years now, until I realized that the technicians will try to double charge you.
I had a maintenance service done and TWO WEEKS later when a tech came back to check something else, he tried to sell my wife the same service that had just been done 2 weeks prior. I asked what his reasoning was for recommending the service. Then I asked him why would we need it if it was just done. I asked him to check the record on his iPad. Once he realized I wasn't stupid he played dumb acting like he didn't know the service was recently done.

This week my wife bought a new garbage disposal at home depot and paid for installation. Little did we know NexGen was the installer. I called Monday to schedule the installation. They said they usually set up installations for the next day. But they had nothing for Tuesday or Wednesday. So, I set it up for Friday between Noon-2pm. I took the day off to make sure no funny business. Friday morning around 10:30AM, they called me to cancel my installation. I asked Kelly, the dispatcher, if there was anything for later in the day because I had already taken the day off of work. She couldn't help me out. I had a leak in my kitchen sink for a week just to have my installation cancelled last minute. I cancelled the installation and found someone else.

I don't plan to use NexGen for any further services and I wouldn't recommend them. If you do use them, make sure you don't get fooled with services you don't need.

I really appreciated Jacob who came to the house for a consult. He was extremely knowledgeable and took his time explaining everything to me. I highly recommend him!!!!

NexGen is like a car dealership. They are your best friend take care of all questions call you back immediately when their in the hunt for money. The minute I said yes to a $5000 repair they were at my house ripping stuff out. But when the left i had concerns about work that had been done and the quality. So I emailed man who took my $ Jeff fine sent pictures asked questions. Never a response. So I tried other person on contact. Jessica tjaden. Still no response so i figure ill email up the chain. Next Yanela Valdez sent her photos and concerns about customer service and still nothing. So just know after you give NexGen air your money they will not want anything to do with you afterwards.

We called NexGen for our AC/Heater needs a while ago. And called them again for our water heater. We are not disappointed. Appointment made and decided that day. Install expectations were met. I would not use anyone else for our HVAC and Plumbing needs. With regards to David De La Rosa, he was transparent on price and what will happen on the install. No surprises or misleading statements. He was pleasant and punctual. Glad to have him come out and take care of us. Thank you David and the NexGen Team. Customer for life here.
