That sounds just a tad bit high if the furnace is only 80% AFUE...

How are your electric rates? Consider a heat pump with that same furnace for a dual fuel setup--that would be nice.

The warranty is good.

Which thermostat?

Sorry, 2 stage thermostat not sure the manufacture included. If I was able to talk them into adding the 95% AFUE furnace for $8225 plus a humidifer. Would this then be a better deal. Thanks

I sure think so. Make sure you get that 2 stage stat. You want everything in writing. "If it wasn't on the contract, it wasn't discussed."

Why are they suggesting a 2 stage AC for your climate? I would think thats overkill--and alot more expensive than a 1 stage AC. How are they sizing the system on offer? Make sure you get them or anyone to do a manual j so that its all sized correctly. Get at least 3 quotes with them doing this as well. Make sure all model numbers are written directly on the quote. Like others said def get a 2 stage thermostat for the furnace; look into honeywell's visionpro IAQ.

Just get a couple more bids and that will tell you if the quote is competitive for your area

I'd definitely scrap the 16i and go for lower end A/C and put the money in the 95% furnace in your climate.

"I live in Colorado if this makes a difference."

- That makes all the difference in the world.

What are your summer/winter temps like?
What is the cost of your natural gas ($ per therm)?
What is the cost of your electricity ($ per kw-hr)?
