Raymond A. Hart founded Hart Home Comfort in 1979. It began as a Cash On Delivery (COD) heating oil company in Babylon, NY. Mr. Hart purchased one truck and made oil deliveries on his own. At that time, the business was servicing local Suffolk County customers out of a two-room office space in the back of a gas station he operated. After about 10 years of working as a COD company, Mr. Hart began allowing his customers to obtain credit with the company and started an automatic oil delivery program. He also attended BOCES at night to learn about heating oil equipment and eventually began to offer service plans.
