We installed a 2 ton 60000btu systems. We added a 10' return in the hallway and a 6' supply into the son's bedroom. The condenser was shifted about 8 foot towards the back of the home. The condenser has been leveled and set on a pad. We added new plenums and replaced the single wall flue piping with the roofer. We must replace the breaker for the condenser. We need a 30 square D breaker (QO type). Jeff will add the breaker tomorrow and check the condenser's pressures. The system comes with a 10 year parts warranty and at least a 5 year labor warranty.
