Local Knowledge Matters

What We See in Irvine Homes

Irvine is unique among Orange County cities, the master-planned neighborhood model means HVAC needs vary block by block. A Woodbridge condo built in 1978 has totally different needs than a 2022 Solis Park townhome. We know which systems your neighborhood shipped with, which failure modes show up at 15 years, and what the HOA will (and will not) approve. Census data counts more than 62,000 Irvine homes built since 2000 alongside the 25,000 that predate 1980, two generations of systems aging on completely different clocks.

1976 to 1985 Master Plan

Woodbridge & Northwood

Original attic air handlers hit by 40 years of Santa Ana heat, refrigerant fatigue and duct collapse are common at year 35.

1970s Hillside

Turtle Rock & University Park

Split-level layouts on single-zone systems struggle with hot upstairs bedrooms, a classic zoning-damper fix, not a new-equipment problem.

2002 to 2008 Luxury

Quail Hill & Shady Canyon

Builder-grade equipment now hitting 18, 20 years; high-SEER replacements pay back fast under SCE Time-of-Use rates.

2014, Present All-Electric

Portola Springs & Great Park

Heat pumps as primary heat, replacements are rebate-eligible under SCE TECH Clean California, and we handle the paperwork.

Preventing Unexpected Breakdowns

Knowing when your block was built tells us what’s coming, so we fix it before you’re without AC in a 95° week.

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.

⭐️⭐️⭐️⭐️⭐️ Update: We completed a regular maintenance service and a couple of weeks later our thermostat disconnected from our WiFi. When I attempted to reconnect, I selected an incorrect setting. OneSeason came out a day earlier then I scheduled to fix this new problem and they got it fixed and let me know my mistake. Once again, great service from an exceptional company! Top-Notch HVAC Installation – Professional, Efficient, and Honest! I couldn’t be happier with my experience working with One Season HVAC for a full system installation. From the initial consultation to the final walkthrough, every step was handled with professionalism and care. The team arrived on time, walked me through all of my options, and helped me choose the best system for my home without any pressure or upselling. Their knowledge and honesty were refreshing. The installation itself was seamless—clean, efficient, and completed ahead of schedule. What impressed me most was the attention to detail. They treated my home with respect, ensured everything was working perfectly, and even followed up afterward to make sure I was satisfied. The new system is running flawlessly, and I’ve already noticed a big difference in comfort and efficiency. If you’re looking for reliable experts who take pride in their work, I highly recommend One Season HVAC. They’ve earned my trust and future business!

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!).

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.

I was able to get an appointment even with very hot weather quickly and we got a new customer introductory price . Technician Daniel told me in advance what he was going to do and he cleaned our outdoor enclosed condensor unit. Our prior HVAC company had gone out of business so a couple of theur good employees in the service field noe work at One Season. They appear to be a good company to service a person's unit.

I have used many AC companies over my years but none have been as complete in their Preventative Maintance as One Season Heating and Air. They are the only company that I will use Thank You
