We have had Markham Heating and Air conditioning service our furnace and air conditioner for over 25 years, and we have been highly satisfied with their professionalism, their flexibility to provide service when needed and their pricing. Markham Heating was recommended to us by the people from whom we bought our house.
When we recently decided to change our old furnace for a high efficiency furnace, they even replaced the new furnace when the unit they installed was not meeting our expectations. We would recommend Loni and his crew highly to anyone needing heating or air conditioning work.
