Thanks to teamwork among the different business segments of Black Diamond, our house is safer. We didn't know that the flexible aluminum dryer vent was clogged with lint - a major cause of house fires. That was found by a Black Diamond electrician who was installing a circuit breaker box (to replace an old fuse box - another source of house fires). We were called by Black Diamond to arrange for an HVAC specialist to come out the next day and install new, modern solid ventilation from the dryer to the outside. Money well spent. We can always count on Black Diamond!
