Hart & Iliff has been keeping the residents of Sussex County comfortable in their homes since 1889. We install and service all types of oil, gas, propane and electric heating and air conditioning systems. These systems keep you warm in the winter and cool in the summer. However, you should be aware that the Energy Master Plan (EMP), promulgated by the Murphy administration, is planning to change the way you heat your home and business by mandating the electrification of your heating system.
