A Letter From the Owner...


My name is Lynn Gray and I am the president of Gray’s Total Green Heating and Cooling, LLC. My Dad had a HVAC business as I was growing up. I remember being in high school and going out on jobs with him as he was teaching me the trade. Back then there was only conventional means of heating and cooling—not like today where there are choices such as geothermal and solar. As the years went by my Dad retired from the business and I started my own.
