I have had a couple quotes on new A/C and Furnace in a home with original equipment dating back to 1989. I am leaning towards either York or Carrier. In trying to do my due diligence with research, you here good and bad for both companies. I am looking for opinions on the following systems:

1. YORK AFFINITY FURNACE YP9C 98% Eff. 80,000 BTU WITH A LATITUDE TCGF 15+ SEER A/C UNIT



2. CARRIER INFINITY FURNACE 58MVC 95%Eff 80,000 BTU WITH A PERF SERIES 16.5 SEER A/C UNIT


The quotes are from several reliable contractors in my area, I realize the installation is as important as the actual equipment and lowest price is not my main consideration.

I would really appreciate any opinions on positives and negatives on the 2 systems? Also if the professionals on this forum think that these 2 manufacturers are not the best option please let me know.

Thanks in advance !!
