What should I know before a new system goes in?
The first decision is which equipment goes in. For whole-home heating, start with how heat pumps and gas furnaces compare on cost and comfort. For rooms without ductwork, weigh the pros and cons of a ductless mini split, including the trade-off between efficiency and how the indoor units look. If ground-source heat interests you, read how geothermal loops are installed and whether Oregon soil suits them.
Any new air conditioner or heat pump also raises the refrigerant question; the refrigerant guide linked above explains the move from R-410A to R-454B.
If a gas furnace is the choice, two guides cover what happens behind the cabinet panel. A high-efficiency furnace produces condensate water, so learn how condensate lines, pumps, and freeze protection keep that water under control. The wiring basics are worth knowing too: how thermostat wires, the control board, and safety switches connect, so you can follow what the installer is doing.
Controls come last. If you want different temperatures in different parts of the house, see how to add zone dampers and a zone board to your existing system. Before you pick a thermostat, compare Nest, Ecobee, and Honeywell on features, compatibility, and energy savings.
What to Do Next
Once you have settled on equipment, the gas furnace and heat pump installation pages linked at the top of this page cover those two systems. If the guides point you toward ductless, read what to expect from a mini split installation.
