  3. Furnace + ACBoth replaced in one visit.

Doing both at once saves a second job and a coil refit later.

Rebates mostly go to the heat pump option and change often: with Xcel gas in the Denver metro they take $6,200–$9,800 off it, less with Xcel electric only. See what applies today.

What people choose now

A heat pump can replace the AC and do most of the heating

A heat pump sits where the AC sits and cools the same way. It also heats most of the winter. The furnace covers the coldest days.
