Hart & Iliff was founded in 1889 by two brothers-in-law, Nathan H. Hart and Louis S. Iliff. The company initially sold feed and grain, coal and building materials. Eventually Hart & Iliff branched out into selling heating oil and installing/servicing heating and air conditioning equipment. After a number of years operating as partners, Louis Iliff bought out Nathan Hart. The business was run by the Iliff family continually until 1971 when it was purchased by Albert & Florence Brand.

"I would like to thank you for the installation of my new boiler. It was very timely and was certainly worry free for me. Please relay my thanks to your installation team for the nice job. Their work was careful and deliberate. I fully agree with the building inspector that they did a beautiful job. I am no plumber, but I can clearly see that their work is pristine!"
