Thinking again about the drop in with the existing ducts. How much does the air handler location matter? Right now it’s in the basement on a far gable end. I would think tying it in at a more central - maybe 15-20’ more towards the center of the house may help ?
Design-wise that would be an improvement, but it most likely would require a redo of the trunk ducts which usually taper down in size as air supplies are taken off the main trunk. That could get costly.

Yeah - I was talking to the guy who first recommended patching the boiler and doing two units. He hasn’t quoted the heat pump yet, but he was basically recommending to hold off on anything for right now other than fixing things that are broken. He said the sheet metal costs alone are turning a 12k job into a 15k job, plus manufacturers are raising prices due to supply problems. I imagine most jobs now are non discretionary commercial and new builds that were already in the works.

$40k is robbery IMO. I still like the idea of patching the boiler, and dropping in a (size matched) HP on the existing ductwork, with no defrost circuitry, and using it for AC and shoulder season heating.

Anyone who want more than $12k for a drop in conventional HP is IMO ridiculous.

Ofc, the current environment is jumping costs, waiting is probably a good idea too.
