Home AC, traditional vs heat pump
Hot part of California, routinely exceeding 100F June-Sept
Current system, 3-Ton split, R22 with evap coil and furnace in the attic (2 story home), condenser unit outside in the side yard.
The r22 evap coil is leaking and not holding charge. Heating performance of the gas furnace is great during winter.
Should I replace current setup with a heat pump, ditching the gas furnace? My electric rates seem exorbitantly high (PG&E @ ~$0.61kWh).
Should I keep the furnace and just swap the coil and condenser?
Do I go with R32 system or a 454B system?
Cheers
