I have the opportunity to save about $5,000 in equipment price by going with 2 ClimateMaster geo units that are 2014 models on closeout. The only real difference is the warranty. Instead of 10/10 on parts and labor, the offered warranty is 10 on refrigeration parts, 5 on other parts and only 1 year labor. Is a better warranty worth the added costs? That seems I could pay for a lot of repairs before making up the difference.
Energy Star requirements to qualify for Federal Tax Credit are here- http://www.energystar.gov/sites/def...rmal_Heat_Pumps_Program_Requirements v3.1.pdf 4) Warranty Requirements: Partner shall provide, as standard, a manufacturer limited warranty for its ENERGY STAR qualified geothermal heat pump models for all parts and labor for a minimum of two years. The major refrigerant circuit components, including the compressor(s), heat exchanger(s), and expansion and reversing valve(s) shall be warranted for parts and labor for a minimum of five years. You will have to decide if the warranty is worth it and Energy Star Qualification.
