Best Solar Panel Installation in Detroit MI

I called oak electric for a furnace clean and check on a Monday.  Was scheduled right away the following week.  The tech, Brandon, was extremely Knowledgeable.  He replaced our filters for the humidifier and the furnace and told me the best brands to buy to replace both.  He even went through the house and made sure the correct vents were open for best heating this winter.  Best company in the Waterford area to call for heating and cooling, in my opinion.
