American standard gas furnace with straight cool condenser. Condenser and coil installed in 2010. Furnace installed in 2014. All electrical connections are tight with no corrosion. PSC blower motor is acceptable. Refrigerant levels were low due to a leaky Schrader valve. Replaced valve and recharged the system with 32oz of r410a. Compressor was amping high upon start up. Installed a compressor saver to help the efficiency upon start up. Outdoor condenser was washed and waxed. Installed a drain switch on the primary drain to prevent water damage.
