Replaced an old heat pump with a new system. Very pleased with the quality of the work and the performance of the system.

Jos Frederick has been our heating/air conditioning service company for more than a decade. Honestly, the level of service and advice varies greatly from one technician to the next. We like their product and in general, their work, but they are expensive compared to other contractors in our area.
