Our house ac compressor was replaced today. The guys sold me a SER13 3.5 ton
American Standard to replace a 3.5 ton Carrier about 10 years old. The new
unit is much bigger. Someone told me that it wasn't good to replace a 10 SER
with a 13 SER because the coil would have to be replaced and at least the
orifices would need work/ or was it replacement. But he said that if the
installers knew what they were doing, he would guess that they could make it
The AC has been running for 5 hours and won't cool below 75 degrees on a
pretty cool day. Google says it's 84F now here in the desert.
Is an orifice or coil problem going to show us as an inability to cool or do
good readings on the guages outside on a ground level of a split A/C furnace
tell the installer everything he needs to know? Any ideas what might be
wrong? He's comming back later today and I want to be able to ask a few good
questions, if possible.
