I found Lincoln Hills Construction through Quiet Cools website and I also had a promotional card. Marc showed up just a couple of minutes late for the estimate, but as it was his last appointment of the day, at 5:30, that was to be expected. He crawled our attic and determined what size would fit. Another dealer had recommended a larger unit without having seen our house. Marc said while he’d certainly love to sell me a larger unit, it simply would not fit in the space available. On installation day, he was absolutely on time. He put drop cloths everywhere he walked and his assistant vacuumed up every speck of dust from cutting the sheetrock. He installed aQuiet Cool unit in the house and a building code compliant unit in the garage. Very pleased with his work.
