Furnace & AC Install
Installed a 97% 100k BTU furnace with an ECM motor and a 4-ton Carrier AC with matching coil, reusing the existing thermostat and lineset. Set gas pressure and cooling speed, fixed the main gas-line flare, added about 2 lbs of R454 refrigerant, and verified operation with a new filter boot and return; everything tested out well.
