Why Choose Same Day Heating & Air Conditioning?

For Jonathan Wintersteller, there isn’t one thing he’d rather be doing — or one place he’d rather be. The San Diego native had spent time in Northern California, dreaming of one day owning his own home services outfit. Now, he has that opportunity. And he gets to do it in the place he grew up in.

“This is a sort of homecoming for my family.” he said. “I’m happy to be here. My wife is happy to be here. This is our home, and always has been.”

He brings with him lessons learned from 30+ years of experience in the home services industry — years of hard work, sweat, and late nights in the office. He comes from Santa Rosa, where he, along with Jon Diamond and Curtis Moore, helped build a regional HVAC powerhouse. In 10 years of business, the company landed on the prestigious Inc. 5000 List five times. 

The leadership team did this by bringing their personal values and beliefs of workmanship and family. They envisioned a loose, fun, but experienced and intelligent team of service technicians and representatives. It wasn’t something they always had in their previous careers as HVAC employees.

“We wanted to build a business that is for the people. For the customers.”

“It’s something we wanted for ourselves at other companies,” said Diamond. “A lot of companies talk about what makes them different from the competition. But we never worked for anyone that lived that. When push came to shove, they made the decision that was best for the house, not for the employee or the customer.” 

The true dedication to fostering a unique work culture that doesn’t focus simply on the transactional nature of HVAC repair and replacement, but instead looks to foster personal relationships with employees and educate customers earned Wintersteller’s company high accolades.

The business won multiple Angie’s List Super Service Awards, was a Certified 5-Star Business by Yelp and Elite Service by Home Advisor. The company was also named in the top “100 Places To Work” By the North Bay Business Journal

“We want to hire for heart and want people to charge that battlefield with us,” he said. “Just do the right thing by your people and your customers. That builds momentum.”
