Paige Heat pump tune up Upon my arrival I performed a 6 month checkup on 1 furnace system and 1 heat pump system. Flushed and treated water removal systems, checked filters, cleaned the flame safety sensor, checked for proper fuel delivery, washed the condenser coil with water then verified system safety and performance. Found the main homes system performing to manufacture specifications and the shop mini split system has developed a leak at the heat transfer media coil inside. This is covered under the customers extended warranty and the necessary parts will be ordered for a return repair.
