Nine months of heat a year, and a system that needs power to start
Polk County needs heat from October through June, nine months of the year. Winter nights average 35°F, so a furnace here runs most of the year, not just a few cold weeks. Summers stay mild, afternoons averaging 77°F, so the cooling side of a new system has an easier job than the heating side does.
More than half of homes here heat with electricity, which makes a new system's efficiency rating matter through most of the year it runs. Wind has knocked out power here before, and across Oregon, a fifth of households went at least 24 hours without it in 2024. A furnace with electric ignition needs power to start even when it burns gas, so that is worth asking about when a new system goes in.

Oregon requires HVAC contractors to hold a state license.
That license comes from the Construction Contractors Board, and it covers the contractor, not any single job. The business is tested and kept on record with the state rather than getting a separate sign-off for each project. Work under $1,000 does not need a licensed contractor at all, but installing a heating and cooling system runs well past that figure, so this job falls under the license requirement.
A furnace, air conditioner or heat pump installation also needs a permit from the local building office in most cities and counties, with an inspection once the work is done. That inspection is separate from the CCB license and looks at this particular job rather than the contractor's record. In Oregon, the license tells you the contractor is on the state's books. The permit and inspection are what a local inspector checks against this installation.

- When should I replace my HVAC system?
- Replace it when repairs start becoming frequent or when a major part fails on a system that's already old, rather than waiting for a total breakdown. Most furnaces and air conditioners last a couple decades with regular service, but the last few years of that life tend to bring rising repair bills and falling efficiency. Homes here run the furnace most of the year, from October through June, so a heating system that's struggling shows it fast. If a contractor tells you a repair costs a large share of what a new system would run, that's usually the point to stop patching it.
- Should I replace my furnace and air conditioner at the same time?
- It depends on the age and condition of each one, not on a rule that says they must match. If both are original to the house and close in age, replacing them together means one installation instead of two, and a new furnace and coil are matched for how they work together. But if your air conditioner is ten years newer than your furnace, there's no reason to replace a unit that's still doing its job. A contractor can look at both and tell you honestly whether one is close behind the other or has years left.
- What happens during an HVAC installation?
- A contractor removes the old furnace and air conditioner, then sets the new equipment in place and connects it to your ductwork, gas line or electrical circuits, and the condensate drain. They'll check the ducts for leaks or sizing problems while everything is open, since that affects how well the new system heats and cools the house. Once it's running, they test it, and gas furnaces get checked for correct venting and burner operation. Replacing a furnace or air conditioner needs a permit and inspection from the local building office, so the job isn't finished until that inspection is signed off.
