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.

All fuels are rated based on their heat content. The unit of measure is a British Thermal Unit (BTU), which is the amount of energy needed to raise one pound of water one degree. Heating oil contains 140,000 BTUs per gallon, whereas propane contains only 91,300 BTUs per gallon. Therefore, it takes 1.53 gallons of propane to provide the same amount of heat as one gallon of heating oil.

We got 4 quotes on a new heating system and they weren't the highest or lowest but we chose them for their knowledge. We were given 3 quotes on different systems with detail on differences in the systems, no pressure to choose one over another as with other companies. Clearly professional and very knowledgeable, we had full confidence in what they were going to do.
Install day was great, very nice crew, all work areas were left very clean. We were given a detailed walkthrough of the system, they answered all questions we had. The company guarantees their work. Look no further if you need any type of heating or cooling systems work.

I have been a customer of Hart & Iliff since 1973 when I moved to the County. In addition to normal oil delivery and yearly maintenance, they have always been there promptly during the times I needed emergency service no matter what the weather. Their technicians have always been knowledgeable and and professional and I have seen a few in my almost 50 years using the company. Hart and Iliff has my highest recommendation.

I have been a customer since 2016. They maintain my furnace, air conditioning system, and provide me with home heating oil. I have also had repairs done on my furnace in the middle of the winter, with one call, the issue was fixed the right way. Everyone from the first phone call to the service visit are professional and kind. I would never think of going anywhere else. I highly recommend them for: quality of work, piece of mind, exceptional value, and consistent results.

As a single mother buying a home, it is a relief to have businesses you can trust and rely on to be there. I have had 1/2 a dozen emergency visits for my old heating system, and not only were they to the rescue quickly {within an hour each time!} they were personable and knowledgeable and empathetic. The "girls" running the office and paperwork are equally professional, helpful and kind. Finally, I was able to speak at length to the owner when contemplating pulling and replacing my underground tank. I am in excellent hands, feels like family and will never leave Hart and Iliff.

I have been using Hart and Iliff for almost 40 years since I moved into my home in Byram Township in 1980. They deliver oil, maintain and clean my furnace annually and always are only a phone call away when I need repair. 15 years ago they installed two new Roth oil tanks in my basement. They are very dependable and reliable and I would never use any other oil company. Lois V.

Hart and Iliff has been our oil supplier for over 20 years and we couldn't be more satisfied with their professional service. They NEVER left us cold when the furnace needed repair, and they are on top of deliveries when a snow or ice storm is on the horizon. THANK-YOU very very much! Sincerely, Patricia Pruser Services: Cleaning, Heating system maintenance

I have been a Hart&Iliff customer since 1993. This company has the best service I have ever received. They are polite, caring and will work with you. The team is responsive and personal. You may pay a few cents more per gallon, but it is worth. They service my furnace annually, I have called them for other items as well. If you are looking for a customer service, personal and overall great company, this should be your choice.

This company continues to impress me with their professionalism. I needed the whistle fill sensor replaced on my tank. The technician had told me last delivery to wait until my next one and check it again because the fitting was an unorthodox size. When he came to fill my tank today (months later) he had a spare one in his truck that he had saved in case in would come in use.
And I don't think they even charged me for it! He just installed it right there in a snap, filled the tank, and was on his way to the next delivery. My family has used Hart and Iliff for years and will continue to do so. Incredibly happy!

I recently had to replace my hot water heater. Because of the lower operating costs and greater efficiency, I decided to get an indirect heater that operates off my boiler. I have had excellent experiences with Hart & Iliff in the past so I called them in to do the work. The men who did the installation were terrific. They were thorough, knowledgeable and careful.
They clearly took pride in their work and it showed. When they were finished, they made certain that I understood the system and how to use it. I remain a very satisfied Hart & Iliff customer.

I've been using H&I for a few years. They installed a new oil burner back around 2013 and did some oil tank work. They're one of the better HVAC contractors in the N. Warren area, rather expensive but worth it to me. Friendly knowledgeable workers, reliable, and they surprised me by following up on a technical detail of their installation here.
