How Stonegate Heating & Air California Was Born in California

It was a Tuesday in July, about sixteen years ago, and the temperature in California had hit 103 degrees. We were working for another company then, sent out to a home in West Covina where an elderly woman had been without air conditioning for eleven days. Eleven days. The company had already sent two other techs who’d told her she needed a full system replacement — $8,400, cash up front. She’d been sleeping on her living room floor with a box fan pointed at her face.

We took one look at her condenser unit. A $47 capacitor had failed. That’s it. Forty-seven dollars and twenty minutes of honest work, and she had cold air again. She cried. We felt sick. That same company had us selling “miracle” air purifiers to scared families and pushing financing on people who just needed a belt tightened. We drove home that night, pulled into our driveway in California, and sat there with the engine running. We called it quits the next morning. Stonegate Heating & Air California started two weeks later with a used van, $2,800 in savings, and one rule: we’d rather sleep soundly than sell someone something they don’t need.

Jason Trent’s Personal Connection to the HVAC Trade

Jason didn’t stumble into this work — he was practically raised in it. His grandfather ran a small refrigeration shop in the Central Valley, and by age twelve, Jason was sweeping that concrete floor every Saturday morning, breathing in the metallic smell of brazing rod and refrigerant oil, watching the old man test pressures with a practiced ear. The shop had no air conditioning. Just a swamp cooler rattling in the window and his grandfather’s voice explaining why every system tells you what’s wrong if you just learn to listen.

That listening became everything. After his grandfather passed, Jason finished trade school and spent his early twenties crawling through attics in Sacramento summers where the temperature hit 140 degrees, the fiberglass itching through his shirt, learning to trace a refrigerant leak by sound and temperature gradient. He loved the puzzle of it. Still does. The moment when a system that’s been confounding everyone else suddenly makes sense — when you find the cracked heat exchanger no one else checked for, or the ductwork buried in insulation that’s been suffocating a master bedroom for a decade.

If Jason weren’t doing this, he’d probably be restoring old motorcycles or fishing the Delta every morning. He talks about both constantly. But the truth is, he can’t imagine not walking into a home where someone’s been miserable for days and walking out with the problem solved. Sixteen years in, he still takes calls himself at 10 PM when a furnace dies on the coldest night of the year. Still drives to La Puente or San Leandro personally when a job’s gone sideways and a customer needs someone who actually cares to show up. The work hasn’t worn him down. It’s deepened him.

Meet Jason Trent — The Person Behind Every Job

Jason Trent is the Owner and Field Supervisor at Stonegate Heating & Air California. He’s state-licensed, trained on systems from Rheem to Daikin to the old York units still running in half the homes built here in the 1990s. Sixteen-plus years of hands-on experience means he’s replaced evaporator coils in crawlspaces most techs won’t enter, diagnosed compressor failures other companies misread as total system losses, and taught every technician on our team to slow down and think before reaching for the sales brochure.

What separates Jason from a corporate franchise technician is simple: he owns the consequences of every recommendation. His name’s on the company. His cell number goes on the invoice. On weekends, you’ll find him at his daughter’s soccer games in Baldwin Park or rebuilding a 1974 Honda CB750 in his garage. That same patience he brings to a carburetor rebuild — methodical, obsessive, unwilling to cut corners — is what he brings to your heating system. He promises to treat your home like his grandmother’s, because that’s exactly where this started.

Our Promise to California Homeowners

Honest pricing. After that July afternoon in West Covina, we built our pricing on parts plus labor with markup that’s transparent, not predatory. We show you the invoice. If a capacitor costs us $47, you won’t pay $400 for it.

Quality parts. We install Bryant and Rheem components we trust because we’ve watched cheap aftermarket parts fail in California’s hard water and summer heat cycles. We warranty what we install because we choose it carefully.

Standing behind every job. In 2019, we installed a furnace in Valinda that developed a board issue three months later. Manufacturer defect. We replaced it on a Saturday evening at no charge, no argument, because “under warranty” doesn’t mean “make the customer wait.” That’s our policy: if we touched it, we stand by it.

Our Credentials

• State-licensed HVAC contractor — fully compliant with California licensing requirements
• Insured & bonded — complete protection for your property and our team while working in your home
• 16+ years serving California homeowners with hands-on field experience
• 499 verified reviews averaging 4.7 out of 5 stars — real feedback from real neighbors

These aren’t decorations. When you invite someone into your home to work on gas lines, electrical components, and high-voltage systems, licensing means they’ve been vetted by the state for technical competence. Insurance and bonding means if something goes wrong — a water line nicked during a furnace swap, a technician injured on your property — you’re not left holding the bill or facing liability. Sixteen years means we’ve seen the specific ways California’s climate stress-tests equipment, from the dry heat of Sacramento summers to the salt air corrosion we encounter closer to the coast. And 499 reviews averaging 4.7 stars means our neighbors keep calling us back, which is the only credential that truly matters.

Rooted in California

We’ve raised our family here, sent our kids through schools in West Covina and Baldwin Park, and built this company one neighbor at a time. Jason still stops at the same coffee shop on Amar Road most mornings. We’ve sponsored youth baseball teams in San Lorenzo and answered emergency calls on Christmas Eve in Covina when a family’s pilot light went out. We know which older neighborhoods in Ashland and West Puente Valley still have the original ductwork from the 1970s, and we know how the Delta breeze affects cooling loads in West Sacramento versus the inland heat in Vista. California isn’t where we work. It’s where we live, where we belong, and where we’ll still be when your next system needs us.
