Meet Seth

Owner of McCoy & Bielenberg Heating & Air Conditioning

Seth McCoy

When I was growing up, my father owned a small drywall company. I worked for him every weekend and summer from an early age until I finished high school. This experience gave me a great understanding of how construction all comes together from raw framing to a finished home.  As the years passed and I continued to work with my dad, I understood more and more that the details of the framing and raw construction is where it counts to ensure a beautiful and long lasting finish.

After high school I joined the Marine Corp.  When I came home I started working with a local company installing heating and air conditioning systems and doing everything from large custom homes to fast paced work in the Bay Area.  After a few years of working there I was introduced to Bob Bielenberg and learned a new way of doing the same job and getting better results.

This new way of installing involved many new details that at first glance seemed minor, but when you add up all these minor details you get results that are far above standard and that set new levels of excellence. This way of providing first class service was the way I wanted to do business.

We formed McCoy & Bielenberg with a mind set of remaining a smaller more personal business that brings a first class system to our neighbors in Nevada County.   Our goal is to make sure that our work provides you with the best system to insure your home’s air quality and your family’s comfort so that you feel good about giving a referral to your family members and friends for The Real McCoy Heating and Air Conditioning.

We are proud of the reputation that we hold and will continue to build. My long term goal with the business is to remain a smaller company delivering what we promise.

Get yourself the Real McCoy.
