I am an old school HVAC tech. trained in R-12 and 22. I have two new Goodman systems installed by 'Who knows?' Systems were installed before cient bought forclosed home. All the low voltage wiring was a disaster. (Obviously done by someone who didnot know what they were doing). One system is R-22 and the other is R-410A. The 410 A system is not operating properly. I put guages on it (the new type for 410A) and the pressueres read 35psi on the low side and 100psi on the high side. Suction line is sweating. Is this anywhere near normal? I thought 410 systems ran higher pressures than 22. I have no temperature drop across inside coil, any suggestions.
