What is your location?

What size/eff furnace and AC are you replacing?

How would you describe the insulation quality of your home?

You are missing size and models on the York and Rudd quote.

Do any of the quotes include new refrigerant line set? How about a box filter and new thermostat?

Just a quick observation that the Trane quotes #1 and #3 are probably grossly oversized on the furnace.

Post back and I will go into more detail on the Trane and Rudd quotes.

IMO

York doesnt have any parts that i know of from China, units are usually assembled in Normon Ok. Some of the equipment is assembled in mexico but most all companys have a manufactoring plant in mexico. Please give us complete model numbers.

All York residential and light commercial Unitary Product Group products are Made In USA.
The equipment on your quote is made in Wichita KS.
Their packaged equipment is made in Norman OK.

Only very large (such as packaged over 40 tons) are made in Mexico.

You can verify this on their website.

I also think you should ask for AHRI matchup numbers when comparing your quotes. Any quote that says "up to...#" is the max that can be attained for that product category of equipment, and may not be what your matchup is rated.

I'm a fan of York/Luxaire/Coleman.
Good quality with alot of features. Their outdoor A/C condensors are very quiet. Alof of my neighbors have them and they haven't had problems.

What part of the country are you in? Whats your electric per KW?

Regarding the term "up to" as it applies to SEER, is meaningless.

It probably only applies to 1 or 2 sizes, matched with a particular evaporator coil.

Ask the contractors for an AHRI certificate for the equipment (model #s)that they are proposing.
