Why Choose Same Day Heating, Cooling, Plumbing?
Bringing Award-Winning Comfort to Sacramento, California
What started less than seven years ago as a vision to change the home services industry has grown exponentially. After building highly successful, trusted branches in San Diego and the North Bay, we are thrilled to open our third location right here in Sacramento County, offering fast, reliable AC repair, heater installation, and comprehensive plumbing services.
Continuing A Legacy Built on Core Values
For Jonathan Wintersteller, there isn’t one thing he’d rather be doing — or one place he’d rather be. The Santa Rosa native had spent time in Northern California, dreaming of one day owning his own home services outfit. Now, he is the owner of Same Day, a leading HVAC & Plumbing company that started in San Diego. After immense growth, Wintersteller opened up his second location, Same Day North Bay. After continued growth, Same Day is proud to land it’s third location in Sacramento, California!
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. Wintersteller, along with Jon Diamond and Curtis Moore, helped build a regional HVAC powerhouse. In 10 years of business, Same Day has 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.
–Jonathan Wintersteller, President“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.
