Customer stated that his heat pump was cooling his home properly but not heating. Upon investigation, I found that the Nest thermostat that was installed was setup incorrectly. Heat pump setting was only set to seasonal instead of every cycle. I corrected settings and heat pump started up in heating with no issues. Recommend annual maintenance

CM Heating performed a Heat Pump Diagnostic - Upon arrival, frost covers top half of coil with some on bottom half and frost on accumulator and TXV. Heat pump however is still operating without shutting off, the temperature from vents is 91 degrees. I replaced the air filter, checked temps across filter drier (no restriction), checked pressures (low side 55 psi, high side 347psi) and added some refrigerant to see if pressures would improve but it didn’t. There is some sort of restriction in the system or it is only going into partial defrost mode. Unable to confirm diagnostic at this time and would need a senior technician to come out and confirm issue. *Maytag unit is still covered under part warranty for another year.* *Completed HP Maintenance on unit. No diagnostic charge
