Casey (who is Ken's son at Fields Service) did a beautiful job installing a propane powered room heater. He ran the propane line from the ceiling of the garage into the sun room, installed the flu to vent the heater and it both looks great and works perfectly. The gas line is essentially invisible and the heating unit itself is mounted ideally. This is by far the best HVAC company Ive ever dealt with they do great work and leave everything spotless and working great
