My home a/c blows but, blows hot in all settings.Its 11 years old and we have a home warranty.There is a co-pay so curious if this is a simple fix.

Check all fuses and circuit breakers for the unit.

Thanks for the help,a/c repair man came out today reversing valve went bad on heat pump,not worth replacing changing the whole unit.

Make sure they also change the inside coil. If not the unit will not meet the listing.
