So with similar sized systems and pricing for a 2500 Sq Ft house in Michigan I have to which contractor to go with based upon my gut feeling aftger interviewing the salemen regarding their company and feedback from this forum.
1) Is there a significant comfort advantage between a 3 Stage Bryant/Carrier Infinity (355CAV... and a Modulating York furnace (PC9-UP...) Both 4 ton AH and 100K input.
2) Bryant offers a 20 Year parts and Labor warranty on the HX whereas York offers lifetime parts (no labor). Are either of these warranties significant (failure rates of current equipment) and would most contractors servicing a Bryant with a failed HX fix it or try selling a new unit with a 30% (or so) credit which is probably the actual York strategy...
3) By buddy's 10 year old Bryant recently had the secondary HX fall apart. Have the new units changed the secondary HX design or materials? Does York have any real HX issues in their 90%+ line (I don't see class actions on York, but I do for Bryant)?
4) Any feedback on the reputation of Andy's Statewide (Orion) Vs Top Notch Mechanical (Waterford) regarding solving post installation problems (if this is against the rules, then please disregard). The BBB only lists Andy's with 2 resoloved issues.
