Need to look deeper than just the brand name, what is the AHRI number if they are bidding matched systems. You don’t go by the outdoor unit ( in this case 16 SEER ) to get your efficiency ratings, it’s a combination of matching indoor to outdoor section that gives you your SEER2 and EER2 ( those are the new standards as of 1/23, certainly they still use SEER and EER and for Heat Pumps the HSPF ) hopefully the bidding Contractors did not let you believe the rating of the outdoor unit alone is what your going to get for efficiency ratings.
What type of outdoor coil does the York use on this model, the tried and true fin and tube or microchannel? Is either important to you? The Goodman uses fin and tube.
Is one Contractor offering a better labor warranty than the other, if so is that a plus in your decision making? If one manufacturer offers a better manufacturers warranty and puts in more standard features into the outdoor unit than the other, is that a plus in your decision making?
What does the bid consist of, is one more detail oriented and they are going to replace existing pieces or reuse them, as an example only, is one Contractor going to replace the outdoor disconnect switch and whip and condenser pad, and even the lineset, while the other are reusing existing pad, faded whip and ( possibly rusty rotting ) outdoor shut off switch.
Post the AHRI numbers if they gave you one, if not ask them for it and post it, or post model numbers of each section. Do you want AHRI ( Air Conditioning, Heating and Refrigeration Institute ) matched systems, is that a plus for you?
Are you interested in any money in your pocket rebates from your state? If so you need a AHRI matched system that says it meets your state’s minimum threshold.
Are you interested in the Federal Tax Credits? as you need to meet minimum threshold for those also.
Not all Contractors are created equal, as one may cut corners more so than another, and have an inferior install and setup, sizing of equipment than another, so choose your Installing Contractor wisely.
