The first time we used Just Right Air was after we had another company install a new furnace. The furnace kept periodically breaking down, even though it was a good quality furnace. The installing company came out several times, but couldn't figure out what was going wrong. Just Right Air came out and fixed the problem on the first visit. We've used them ever since, and are always extremely pleased with their wonderful customer service and are impressed with their extensive knowledge of heating and cooling units.
