Good: Technician Matt, repaired my defective boiler part by methodically cleaning the areas that had plugged up with sludge(saving me big bucks by avoiding replacement). He also noticed a gas smell coming from my hot water heater and tightened up the loose fitting(not part of the service call); and he noticed a low battery issue on my thermostat, which I had overlooked.. Other: repair made 9-28-11.
