S'dale Air & Heating installed our new system several years ago. As a former engineering AC design and maintenance engineer, i was pleased with the design and installation. I have a maintenance contract with them. Their twice annually maintenance is performed by skilled AC techs. I'm pleased with it.
i have referred them to an engineering friend who had complaints with his current system. Problems were resolved by S'dale AC.I especially appreciate the prompt response when the occasional problem arises.
