About Us
A Family Business Built on Trust
Steven Williams started Seneca Heating & Air Conditioning in 2000 with one goal: treat every customer the way you'd want to be treated.
Our Story
With over 35 years of hands-on HVAC experience, Steven Williams has seen just about everything. He founded Seneca Heating & Air Conditioning in 2000 to bring honest, reliable service to the Finger Lakes region — the kind of service where you actually know who's coming to your door.
We're not a franchise or a big corporation. We're a local team that takes pride in doing the job right the first time. Every system we install is personally designed to fit your home and your budget — not a one-size-fits-all solution.
When you call us, you'll get a straight answer, a fair price, and a team that shows up when they say they will. That's been our promise since day one, and it hasn't changed.
