You have a home warranty and they won't fix it? What reason did they give you?
Post the mod numbers of both units.
Some one may be able to verify either way if that is a match.
Some brands did use larger indoor units then outdoor units.
that tech that said that could could very well be full #### a 4 ton drive furnace on low speed blower could be just right and the oversized coil should not be a problem . there is a possibility that it could be a properly matched system
Depends a little on brand.
OD unit, look near where the copper lines attach to it. Probably just above them.
ID unit, look around where the lines attach also.
If you also have a furnace, it should be inside the access panel.
OK Found the numbers..
OD Coleman cooler 10
model number BRCQ048B
Factory charge 5.13 oz
model number CIQA-036U-B
charge 1 oz
Think I found the problem.. They OD unit specifies a 40 amp breaker. the breaker that keeps flipping is a dual 30 amp breaker!
Good. Because that is a bad mismatch.
you need a new matched system
