HVAC unit is basically combination of HVAC chiller and all related equipment. See below related link for all details
Typical superheat refers to the amount of temperature increase in a vapor refrigerant beyond its boiling point at a given pressure. In HVAC systems, a common range for superheat is between 5°F to 20°F (about 3°C to 11°C), depending on the system design and operating conditions. Proper superheat levels ensure efficient cooling and prevent liquid refrigerant from returning to the compressor, which can cause damage. Monitoring superheat is crucial for optimizing system performance and energy efficiency.
Suction superheat is the heat added to the refrigerant above that required to change its state from liquid to vapour (as happens in the evaporator). This heat is added both in the evaporator, in the suction line and (where applicable) in the suction accumulator.Discharge superheat is suction superheat plus heat of compression, and must be removed in the condenser before condensation, the change of state from vapour to liquid, can occur.The HVAC Veteran
Undercharge can cause HIGH superheat. Overcharge can cause LOW superheat. You need some superheat when charged correctly. How much is needed is depending on outdoor air temperature and indoor wet-bulb temperature.

Model # for Lennox HVAC unit
there is no set answer ,you have to ajust pressure using subcool and superheat. if these terms confuse you i recomend calling an hvac contractor
Plug your unit into it and play it loud
Induction Unit
To condense
Because the drain is clogged.
