Today certified was in the Richmond area on call doing a wall furnace installation. We removed the old floor furnace, patched the flooring and installed new flu piping with a new roof jack. It was a emergency install as the clients were elderly and out of heat. Even though we work Monday thru Friday, we will work weekends as well if it’s needed to save the day for a person in our community
