HVAC reviews in Anaheim, California

Daniel H was very courteous and informative!! I appreciated his hand drawn diagrams explaining everything he did!! He left some insulation material as he was leaving and was also a little pushy regarding the Google review, but he still did a good job overall

I was very pleased with the installation of my new heat pump system. Kyle and Damion went above and beyond to make sure that everything was working properly and even went the extra mile to connect duct that was not done properly by prior contractor. They made sure everything was cleaned up and back to original condition. I would definitely refer them to anyone in need of A/C Repair or installation.

Fernando was excellent! Extremely helpful, knowledgable, and professional. He gave a thorough and understandable explanation of every aspect of the furnace and air conditioning units. He never made me feel hurried and took the time to answer all of my inquiries. He provides excellent customer service. Without a doubt, I would suggest him to anyone in need of HVAC work! Thank you Home Comfort USA!

We were having a problem with our heater and AC and NexGen sent Felipe to come out to see our unit. Felipe provided fast and friendly service. He worked tirelessly to make sure we had peace of mind and was able to help us get a great deal on our new HVAC system. Thanks NexGen for sending us Felipe!

The experience I had with Nexgen was great. Benjamin and Juan were able to diagnose the problem and repair the issue promptly. They repaired my Heating unit and also suggested the maintenance service which is a great deal that I signed up for.

Lukas is very knowledgeable; came up with a good solution to be able to complete the job. Placed makeshift hose from water heater to a bucket then placed a pump into the bucket to let water out through a hose to the back yard. GENIUS!! A++

Anthony and Juan Carlos did a great job and were extremely friendly. I'd recommend them anytime!

Javier did a fantastic job was very thorough with his work and explained everything that he had done. Also gave some great insight on other products.

Tony was a great representative from NexGen, very knowledgeable, very thorough inspecting the heater, the air conditioning system, and making great recommendations. I learned a few things and I will definitely be using their services in the future to do all of the recommendations.
Thanks Tony!!!

I have nothing but great things to say about working with Nexgen. Our Air Conditioning system is so much better now than what It was when we bought the house. Turner and Javier came out for a scheduled maintenance today and were super professional and helpful. They changed out the filters and made sure everything was In perfect working order. Very pleased with everything 👍

We had a very positive experience start to finish on our NexGen HVAC replacement. The salesperson listened carefully to our needs and proposed several options. A very professional installation crew arrived and completed the job over the two-day time frame they had indicated. The lead technician patiently explained how the system worked, including the new Smart Thermostat, and the technicians took care to ensure the house stayed neat and clean during the process. Appreciate their professionalism!

Great installation service! The technician was professional, on time, and completed the job very cleanly. He checked my old flange, used the best materials, and made sure everything was working perfectly. Very happy with the result!

The nextgen team serviced my HVAC system today and provided well-informed and professional service. I appreciate their transparency throughout the service call. Nextgen has become my trusted source for all of my HVAC and plumbing needs!

Everyone I've worked with at NexGen has been super friendly and professional. I had a new HVAC system installed by them a few years ago, and have had them clean and service the unit as well. All around nice people and company! I recommend!

NexGen attempted to upsell me by thousands. I strongly recommend getting a second opinion when using this company—it could save you a lot of money.

Context: My A/C was blowing warm air, so NexGen sent three technicians (two in training). My Nest thermostat was working when they arrived. They inspected the rooftop unit and returned with a quote of $12,500 for repairs, or a full system replacement for $14,000–$20,000+ with financing options. My wife and I left for a two-week vacation the next day, unsure of what we’d be facing when we returned.

After coming back, we scheduled a second opinion. That technician immediately found the thermostat was no longer functional, bypassed it to get the A/C running, and replaced a bad capacitor. Total cost: $350, plus $140 for a new thermostat.

NexGen charged $88 for the diagnostic, left the thermostat nonfunctional, and provided an assessment that did not reflect the actual issue.

Bottom line: A second opinion revealed a simple, inexpensive fix. NexGen’s diagnosis was significantly off and could have led to unnecessary and very costly work.

We've have been with NexGen Air since 2018 after they installed our A/C unit and gave us great services with plumbing as well. Fast forward to August 2025, we contacted them on Sunday, 8/10/25 after our A/C stop running and could not start. A tech was scheduled for 8/12/25 to be at the house to diagnose the problem. The tech sounds very knowledgeable and confident that the problem with our unit is due to an old O-ring in the condenser's line. He said the refrigerant was depleted and required 8-9 lbs of R-22 and quoted around $2080. The price was steep, but I trusted his judgment and trusted the company to fix my issue. In hindsight, I should've at least get a second opinion.

The very next day, 8/13/25, he came back to pumped the refrigerant and the A/C system started again and I thanked him and paid him thinking our problem was fixed and everything is great again. Not even 24 hours later, on the night of 8/13/25, the system is running but the air wasn't cold, but an odor was present throughout the house. In the morning of 8/14/25, the A/C unit would run but making sputtering noises. We contacted the tech and he said he would be there to check it out. He checked the refrigerant level again and now the level is back to almost zero since all 8-9 lbs of refrigerant he pumped in the previous day had leaked out. This led him to check our attic and discover the major leak in our evaporator coil.

When asked about the cost of the new evaporator coil, the tech stated that management is willing to give us a discount and it would be $6000 minus the $2000 we paid, so total would be $4000. We asked if they would help us out since other companies are charging on average $4000 for the new evaporator coil. They were firmed with their $6000 price and would not lower the price. We gave them the opportunity to make it right to fix our issue at the market price, but they still stand firm and refused. We ended up going with a local and more trustworthy company to replace the evaporator coil and finally our A/C system is working like new.

We call and try to get our money back from the botched job NexGen did that not only left us without A/C for a week in this year's heatwave, but also breathing in the refrigerant that the EPA is phasing out. We were promised that Nancie will call us back, but days went by but no call back. We call again and again, but the same promised was made but still no call back. Please learn from our mistake and do not trust in a company so wholeheartedly. Do some research and ask for multiple quotes before deciding on a major repair. We were once loyal customers, but NexGen does not care about our loyalty, they only care when they haven't gotten your money yet.

I live in a condo where my heating and air conditioning were all connected to my water heater (Hydronic system). A couple of years ago, my water heater went out. A local plumber replaced it but something went wrong. From that time on, I could either have hot water to shower or I could have a heated house… but not both. Several attempts were made to remedy the problem without any success. A friend from church recommended NexGen HVAC and Plumbing.
Marc V arrived to assess the situation. He put a plan together that would allow me to have a heated home and a hot shower in the winter as well as air conditioning and cold water for drinking in the summer. Marc made certain to work with within my budget. He went out of his way to ensure I would be happy with both the system as well as the price. Such a sweet guy.
Danny S and Ricky came out two days later to install the system. They were able to separate out the system so heating and air would not affect my hot and cold water. What a blessing!
Marc, Danny, and Ricky were professional, friendly, approachable, and oh so nice! I can’t sing the praises of these guys loud enough. They were fast, efficient, and performed high quality of work. They put down protective floor covering and cleaned up before leaving.
Gentleman, thank you for being a blessing to me!!!

This was an A/C tune-up booked as a Home Depot Black Friday special. Technician Carlos O. was on time and a good communicator. He was thorough and kept me updated on his work findings, explaining each step to my satisfaction. Carlos used shoe covers in the apt., cleaned up the work area when he was finished, and offered some extra-cost options to consider, without pressure to buy. The special pricing was excellent, and I would have Nexgen back if my A/C system needed any work in the future.

Very disappointed with this company despite their good reviews. Was referred to them by a plumber who suspected a hot water slab leak. A very nice technician came out to do the inspection but *never* sent a detailed report, just a few lines on an invoice. This was 3 days ago. I’ve been chasing them down for 3 days trying to get ahold of the technician or simply a more detailed report so that my plumber can break concrete with confidence. Have just been told time after time that someone will get back to me but no follow up has been made and this is delaying repairs/my access to hot water. Very disappointed and frustrated.

Nexgen helped with a plumbing problem in one of my rentals. Same day service at a great price, $88! Thanks again Nexgen.

Mason showed up yesterday as a simple tune up and installing a Captura and it was perfect and at a great price. Even though he ran into trouble while installing he took his time and patience. Ended up being one of my best experience's.
