Performing free second opinion on system that is not cooling properly. Another company diagnosed a refrigerant leak and recommended a leak search and repair + adding 8 lbs of R410-a refrigerant. Full diagnosis revealed that system does not have a leak, refrigerant level on high side is over 470 PSIG which is past the burst point. Diagnosed failed TXV metering device and made recommendations for repair or replacement of the evaporator coil.

Performed free second opinion diagnostic, found dual run capacitor not correct size for system, contactor burnt and pitted, compressor at max amperage draw and shut down while performing test on system. This is due to failed metering device in evaporator coil. Blower motor leaking oil and over amping as well and will fail.

Performed diagnostic on heating and air system, found thermostat blank which is powered by furnace. Found high limit switch tripped due to dirty evaporator coil and dirty blower. Reset limit switch and tested system. In heating the inducer motor is at its max allowed power consumption, and in cooling the system operates but compressor is using a high amount of energy with low load conditions. Same issue will happen again unless system is cleaned. Blower motor is leaking oil and heat exchanger has rust and thermal stress marks caused by the heat not being able to flow through furnace properly
