- Al Noster

The water line to our whole house humidifier cracked and water started flooding our basement. Candy immediately diverted a service call technician to us. We were able to turn off the water while the tech made his way to our home. He proposed a solution to bring our unit to code and ordered the parts to fix the situation the very next day.
