I recently completed a home service project that involved the installation of a Mitsubishi two-zone heat pump system. The project included the installation of a new condenser, line sets, wiring, condensate components, and all necessary cover guards. The system was pressure-tested at 455 psi of nitrogen for 20 minutes, then vacuumed down to 297 microns before releasing the factory refrigerant charge. All system functions were tested and verified for proper operation. Additionally, I provided the homeowner, Heidi, with a walk-through of daily system use as well as guidance on recommended short-term and long-term maintenance procedures.
