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.

"Service is always pleasant and courteous - also phone response is terrific."
"We are very pleased with the service you gave us in fixing our air conditioner. Each person who came to home was understanding and sympathetic to the situation at hand. The number of days and long hours the team worked during the one of the hottest summers on record, far exceeded our expectations. Thanks to all who worked to get our air conditioner back on-line."
"I would like to express my gratitude to your company for sending such a competent service technician to service my heating unit. His work is beyond the norm. He serviced my unit completely as it should have been. He was thorough, neat and clean. He likes his job, he speaks very highly of the Hart & Iliff Company and its members. Again, thank you so much for employing such a fine man. Its always nice to be able to praise someone who has earned it."
