We heard about Bruster from friends who had them install air conditioning. We have a 2-story house with 2 older furnaces and wanted air conditioning on just one furnace serving the 2nd floor. Installation was fairly smooth however when we ran the A/C overnight we found the cooling performance was not good. I called Brian at Bruster the next morning and they promptly had 2 servicemen (Rick & Dave) out to check the system. They worked diligently checking solder joints, pressure levels, coolant charging, etc until finally replacing a suspected defective cooling coil mounted in the furnace. That solved the problem and we are now very satisfied with the air conditioner and even more satisfied with Bruster's servicemen. Bruster also installed a similar air conditioner at my son's house, which went smoothly with no problems. I would recommend them to family & friends.
