"Have been a Gold Plan customer since you installed our Buderus boiler. Have only had to use preventative maintenance till the other night. When the boiler stopped functioning at midnight under below zero conditions, your tech arrived within an hour and diagnosed problem and got the system working until new parts arrived. Very impressed by your HVAC personnel."
