Trane Heat Pumps
We live in Seattle in a home with 1520 sf of heated space. The average heating degree days here is 4,615 and the average cooling degree days is 192. We are taking out an oil furnace and do not have access to natural gas. Our electricity cost is at 9.87 cents per kWh. A contractor we are considering has proposed three alternative Trane heat pumps.
1. Trane XL15i, 2 ton, with variable speed air handler, 15 SEERm, 9 HSPF, removal of oil furnace, standard warranties, includes Trane 600 programmable thermostat and standard filter. $7,200.
2. Trane XL16i, 2 ton with communicating variable speed air handler, 16 SEER, 9.2 HSPF. Everything else the same. $8,400.
3. Trane XL20i, 2 ton with communicating variable speed air handler, $10,200.
Suggested Options: 1. Trane Clean Effects whole House Air Cleaner $998.
2. Trane ComfortLink IIThermostat - full color intelligent thermostat $550.
My initial reaction is we don't need either of the upgrade options and I see little reason to pay for a higher SEER unit since we probably will never use the air conditioning more than 1 or 2 days a year.
We do qualify for substantial rebates in our energy modernization plan, about $4,500.
I would appreciate your thoughts and also wonder if we should be considering the Carrier unit with the 13 HSPF.
