HVAC reviews in Irvine, California

Aubrey came out to install a smart thermostat that we had, but one of the parts was defective, so he wasn’t able to complete the installation on his first visit. He didn’t charge us until we got a replacement part and he completed the installation on his second visit. He was punctual, friendly, tidy, and knowledgeable - I will call again when I have another HVAC need.

I can't recommend these guys enough. Everyone of their staff is super knowledgeable, professional and friendly. The process was smooth from beginning to end with zero hiccups. I did a HVAC system install with new ducts and everything came out perfectly. You can tell they care about the quality of the work, and I would absolutely go with them again on the next project

Aubrey came out to my house for an inspection and cleaning of my heating system. He was exceptional! He gave me detailed information and instructions about what he was doing and how to care for my heating system moving forward. He cleaned the whole unit which was very very dirty and he kept me informed every step of the way. He also changed out and replaced my filter which was also very very old and dirty. I will definitely recommend one season heating and air and I will definitely be calling them to come back for my next service! Thank you Aubrey and the rest of the team!

One Season Heating and Air Conditioning came out to work on our remodel, and they did an incredible job. They were excellent communicators, were punctual, and did a quality job. They also demonstrated a high level of understanding in diagnosing the needs of the space and giving us reccomendations for how to optimize the system. Do yourself a favor and call One Season Heating and Air Conditioning!

Highly recommend One Season Heating & Air! We had them out a couple of weeks ago for a quote to replace our HVAC system. Chad provided multiple options, explained everything in detail, and walked us through financing. We’re thrilled with the results—our home is so much more comfortable, and the new system is incredibly quiet.

I couldn’t be happier with my experience working with One Season HVAC. From start to finish, their professionalism, expertise, and attention to detail were top notch. The team arrived on time, communicated clearly, and treated my home with great care.

They diagnosed my system quickly and explained everything in a way that was easy to understand. Unlike many subcontractors, there was no upselling.. just honest, knowledgeable service.It’s rare to find a company that’s both technically skilled and genuinely customer focused, but One Season HVAC delivers on both fronts.

If you’re looking for reliable, trustworthy, and skilled HVAC professionals, I highly recommend One Season HVAC. They’ve definitely earned a loyal customer.

One Season Heating & Air did an excellent job with our furnace maintenance. They arrived on time, were very professional, and walked me through everything they checked. The service was thorough, the price was fair, and I feel much better knowing our system is ready for the season. Highly recommend One Season for reliable and honest HVAC service!

I had One Season out to do a laundry list of enhancements and repairs on my heat pump systems. They came promptly to perform an estimate, prices were very reasonable, and they scheduled an appointment for the following week. They showed up on time, worked quickly and cleanly, and the installations they did look excellent. I really appreciate the prompt, clean, and professional work!

Thank you to One Season Heating & Air for coming out and repairing our heater! They were able to come the same day, the pricing was fair, and they got everything working quickly. Our home is warm again and we’re so grateful. Highly recommend this company — we’ll definitely be using them from now on!

We scheduled a furnace tune up and Aubrey showed up right on time and did a thorough job. He pointed out parts that we should watch for issues but didn’t push us to buy anything unnecessary. This is the second time he’s serviced our HVAC and he’s always been very friendly and honest. Would highly recommend!

From point of contact through job completion, my experience with One Season was exceptional in every way. The team is very patient and kind, like a friend over for a visit. They are knowledgeable and good communication. The work quality is top notch. The equipment is high quality. I highly recommend using One Season.

One Season Heating and Air Conditioning was fantastic from start to finish. We have two HVAC systems at our home, and one of them hasn’t been operating. Aubrey came out and helped diagnose the issue thoroughly—there’s a leak somewhere in the refrigerant line, and with refrigerant costs being so high, we were worried this would turn into an expensive “quick fix.”

Instead, Aubrey took his time, explained what he was seeing, and came up with a really thoughtful solution. There was absolutely no pressure and no sense of a money grab—just honest guidance from someone you can tell genuinely cares about helping people.

If you’re looking for an HVAC company that’s professional, transparent, and truly customer-focused, I highly recommend One Season Heating and Air Conditioning (and ask for Aubrey!).

Huge thanks to One Season Heating & Air for their quick response and excellent service! Aubrey came out promptly for an AC tune up and repair and had our air conditioning working on the spot. He explained very clearly the entire process and what was done. Fair pricing, professional, and reliable. I highly recommend them and will definitely be using them for all my HVAC needs moving forward.

I had a replacement A/C installed today.
I would give One Season 6 stars, if I could. They were the best of 6 bidders I had. Aubrey had worked with me tirelessly to find a solution for my very difficult space constrains. He and Mike were also super patient while working out the "legalize" of the contract, which I was insisting on. And finally, they both as well as Josh and Ben have done a superb job replacing a condenser and a coil today. Everything was done meticulously, all my questions answered, every step of the process explained. All 4 were were nice and extremely professional. The work areas and the house front were left clean. I highly recommend this company for anyone's heating or A/C work.

These guys killed it they showed up around 9 AM and by 3:30 they were wrapped up heading for home an amazing job if you need a new AC heating there your choice and the price was great.! Also, please take a look at the detail of how they strapped the unit to the base and then the base to the concrete amazing attention to detail!

One Season is an amazing HVAC company who was very professional, trustworthy and knowledgeable. We had to replace our air handler and heat pump. They offered to repair the equipment but we opted to replace due to various issues with the unit. The One Season team, especially Aubrey and Mike were very kind and professional. They were patient with all the questions we asked and made themselves available by phone whenever we needed to reach out. The removal and installation of our new unit was very streamlined and only took a day to complete. The team, including the office staff was very helpful and a pleasure to work with.

Phenomenal service from the bidding process through installation and all the way to their follow-up. You can tell the owners have put considerable effort into systematizing their customer service. Aubrey handled my account, and is an absolute pro.

Their pricing isn’t cheap, but after going through an extensive bidding process with six reputable HVAC installers, they are fairly priced for what you get.

These guys are the real deal. Honest. Reliable. We had a big HVAC issue that they solved timely. We felt fully taken care of and would absolute recommend this company.

Thank you to One Season Heating & Air — I had no idea how thorough a furnace tune-up could be until now! The technician took the time to show me the blower motor and explained how dirty it had gotten. It was eye-opening and really showed the value of proper maintenance. I’ll be signing up for their yearly maintenance plan to make sure our system is serviced twice a year and that my family is breathing clean air year-round. This team has been truly amazing to work with — highly recommend One Season!

Thank you to One Season Heating & Air for doing such a great job on our furnace tune-up. We like to get ahead of the season and have it done before the cold hits, so we know our heater is safe and ready. They even showed us before and after pictures of the blower, which was really reassuring. It feels good knowing our system is clean, safe, and prepared for winter. Such a great company. I highly recommend!

I vet companies that I deal with as thoroughly as possible. One Season Heating & Air-conditioning Are former SoCal Air Flow Pro's from Chad the Owner To Aubrey a lead Tech, Rebecca ( Office Manager) & Sydney (Customer Service) always exceeding my high expectations.

Rebecca the office manager was super responsive to my requests/ questions. She never dismissed any of my extra concerns, and even made sure that they were addressed to my utmost satisfaction.

Sydney in Customer Service possesses professionalism and a great interpersonal skill set which IMO - a true asset for the One Season Team

Tysm Rebecca & Sydney !

Aubrey the lead technician is very experienced and skilled. He showed up during the time range provided to me, and called beforehand to provide me with an ETA. He even put on booties when entering my house!

Also, I find the entire One Season Team to be trustworthy. They never tried to upsell or fear monger like Triton or Goettle who used their Acquisition of SoCal Air Flow Pro's to gain entry into my home to try and sell me plumbing and inspection services (Customer Beware!). I schedule for a HVAC check up and they send me a plumber who states the HVAC associate will call in a few days and bever did!

One Season is a unicorn in today's service business: exceptional and skilled employees, honesty and fair pricing that does not prey on homeowners at their moment of vulnerability.

Wholeheartedly recommend!!
