Reducing our carbon footprint. Harry Clark installed 9 KW solar system on its office building in 2010.The panels cover most of the roof. All of the lighting has been upgraded to LED type. We have modified our fleet mix to include smaller vans, flex fuel vans and incorporated GPS to help reduce the miles per day. These simple measures make both environmental and business sense.

Recycling, lesson learned.

Jack Yaeger a holocaust survivor lived n the woods of Poland during World War II. During that time Jack learned not to waste anything. After the war he immigrated to USA and settled with his wife in Oakland CA. He became and entrepreneur and his main business was recycling. He would visit plumbing and electric shop through the bay area for over 50 years recycling metal and making sure things were not going to waste. For two generation Jack visited our shop weekly. Jack has since passed away but his legacy of recycling is part of our culture here at Harry Clark Heating and Air Conditioning. We recycle refrigerants, metals, cardboard, batteries, mercury thermostats and more.
