The pressure depends greatly on the ambient temperature outside. There are two methods I use for charging a system

1. Is calculating the superheat
2. Is calculating the sub cooling.

Any good service technician will use these methods.

Difference in seer


i would check fan speed. it's probably on high. you might be moving more air with new system. a dirty evaporater on old unit woud have gave you a larger temperture drop.

Hello, Usually it has to do with the quality of the install and the brand. If it was not installed properly from the beginning then the equipment will fail prematurely. As far as the heat exchanger goes I have replaced many heat exchangers on Goodmans after 3 years being installed, Goodmans are prone to bad heat exchangers.

Air condition jsut 10 month old ... not keeping up whith cooling


If it's only 92° outside and the unit won't cool the house, then the unit is either to small or it's low on refrigerant. They are designed to cool a house with outdoor temperatures up to 115° to 120°.Usually you need one ton a/c for every 400 square feet of house, but, you have to take into account for average outdoor temperature and humidity, windows, doors, especially sliding glass or patio doors and which side of the house they are on, insulation in walls and attic.
The air leaving your duct work going into the rooms should be about 20° lower than the room temperature, if you have a 80° room then the air leaving the duct should be around 60°. if it is then the unit is probably to small if, everything is working properly.

A/C fan is running but no cool air


Make sure the outside unit is running. If it is then you may need to get the unit charged.

No heat, got great a/c....


W1 and W2 are the differences from the single stage to the two stage. Im thinking its your thermostat is not programed for 1 heat / 1 cool. You probably had 2 heat / 1 cool before.

I install them every day and I have not had one make a loud grumbling sound. Sounds like you might have a low voltage (Thermostat) wiring problem. The only thing different inside the indoors unit from heat and cool is the fan speed, electric heat when on. The fan might be loose or out of balance and it only shows up at low speeds. Either way, the noise is not normal.
