Not sure how but that’s a hell of a deal. I’ve gotten 6 quotes and nothing near those numbers.

I negotiated and that’s with R8 ducts instead of R6.
His original price was around $24,000 and I asked him how close he could get to $20,000 bc my budget was that and he said $20,000.

You did good, and those are good systems. I suspect they can install those units quicker on new conduction and save a good bit in labor costs that could be passed on to you, compared to a change out where the old unit needs to torn out, moved out of the house, disposed of, new system brought in refit to existing duct work, etc.

This is what I figured as well. It’s crazy the difference in quotes I received. I have a quote for single stage system as low as $17,000 and some variable speed systems around $35,000.

Based on Manual J calculations or you measured duty cycles during the peak cooling season? If your existing unit is oversized, your new unit will be too.


No clue haha, just hoping AC guys got it right. It’s the only AC for the downstairs so seems right based on square footage.
