The underlying prices behind this page.
Two years ago, I paid about $21k for a full furnace replacement and addition of A/C for a 2400sqft house. No duct work was needed, but it required some additional work.
A-Action Heating and Cooling replaced the furnace & AC 18 months ago for about $20K. There was a long waiting period due to supply chain issues.

"Installed a larger than average Lennox furnace and AC for a discounted price. No ducting work, just new furnace vent installed."
