DSB is terrible. The owner attempted to provide me with HVAC equipment of lower quality than what was purchased. They have been very difficult to get a hold of over the phone, and have been late and missed scheduled appointments. They have been disorganized and inefficient in the installation. It took them many, many months to get the work completed.
To their credit, the actual quality of the installation seems ok, and the building inspector gave the installation a passing grade once it was complete; however, there are many other HVAC contractors in the area, and I would definitely go with one of them if I got a re-do. If you do go with DSB, do not pay more than half of the price until the equipment is fully installed and operational. If I need any warranty work done in the future, I will request that the furnace vendor find me a different contractor, as the experience of working "with" DSB was completely unacceptable. read more
