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.
