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.

  • Very professional and easy to work with. Not only did they have a very good solution for replacing the old furnace and air conditioner, but they also redid much of the ductwork so everything works better. I highly recommend One Season!

    Daniel awesome He took time to explain the process and his findings My unit is older and the filter is not a common size. He took time to go purchase one. Best of all he did not try to sell me a new unit. He was courteous and answered all my question I will continue to use this company and request Daniel

    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!!

    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.
