Compare Carrier Model 25HNA936A003 versus Model 25HPA636
In need of ADVICE !!!
I plan to have a new HVAC system installed. The contractor originally provided a quote for Goodman system, with a $2600 option to upgrade to the following Carrier system:
Carrier “Infinity” Model 25HNA936A003 air cooled heat pump condenser rated at 19 SEER. This unit is a two (2) stage air cooled condenser matched with the Carrier “Infinity” Model FE-4-ANF-004 variable speed air handler and the Carrier “Infinity” Model SYSTXCCU1D01 controller for two (2) stage heating and cooling and dehumidification
When I informed the contractor that I was ready to move forward on this project, he submitted the final contract for the same price ($2600), but with the following Carrier system specs:
Carrier “Performance” Model 25HPA636: 2 Stage / 3 Ton – 1.5 Ton / 36,000 Btu – 18,000 Btu air cooled heat pump condenser rated at 16.5 SEER, 208/230 volts, 1 phase, 35 amps, R-410A refrigerant; Carrier “Infinity” Model FE4-BNF-003: 2.5 to 4 Ton / 1000 to 1600 CFM variable-speed indoor air handler; Carrier Model KFECH0320N20: 20 KW electric heater package; Carrier “Infinity” Model SYSTXCCU1D01-B: 7 day digital programmable thermostat Controller with dehumidification and fan cycle modes
1) What is the difference between the Carrier Performance vs. Infinity model?
2) What does the change in SEER value mean?
3) Are both models current - meaning not discontinued?
4) Which package is best?
