Nine months of heat, mild summers, and a grid that doesn't always hold
McMinnville doesn't ask much of an air conditioner. Summer afternoons average 77°F, mild enough that cooling barely counts as a season here. The furnace is a different story. Winter nights average 35°F from December through February, and homes here need heat from October through June, nine months a year.
Most homes in Yamhill County heat with electricity, and electricity doesn't always stay on when it's needed. Across Oregon, 20% of households went at least 24 hours without power in 2024. A new system should hold up to nine months of steady use, and come back on by itself when the power does.

Oregon requires HVAC contractors to hold a state license.
The Construction Contractors Board licenses the contractor, not the job. That license is on file with the state and follows the business from one project to the next. Work under $1,000 is the exception Oregon carves out, but a heating and cooling system installation runs well past that, so this job falls under the license requirement.
For a job this size, the license tells you the contractor is on record with the state. What confirms the work itself is the permit. In most cities and counties here, installing a furnace, air conditioner or heat pump needs a permit from the local building office, and the finished job gets inspected before anyone calls it done.

- When should I replace my HVAC system?
- Once repairs start happening every year, or the system is old enough that a breakdown could leave you without heat for days. Around here that matters more than most places, since homes need heat from October through June. If a technician tells you a repair will cost a large share of what a new system costs, that is usually the point to stop patching it and replace it instead. An aging furnace or air conditioner that still starts every morning can still be close to the end of its life.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, it usually makes sense to do it together. They share the same ductwork and often the same electrical and control wiring, so replacing one and leaving the other means whoever installs the new piece has to work around what the old one left behind. Homes here need cooling zero months a year and heat nine months a year, so a contractor can help you decide whether pairing the replacement makes sense given how little the air conditioner actually runs. Either way, a contractor can look at both systems and tell you what fits your house.
- What happens during an HVAC installation?
- A contractor removes the old equipment, sets the new furnace, air conditioner or heat pump in place, and connects it to your ductwork, gas line or electrical circuit as needed. They check the ducts for leaks or damage while everything is open, since sealing those up now is easier than coming back later. Once the unit is running, they test it, set the thermostat, and walk through the connections again before closing anything up. In most cities and counties, this work needs a permit from the local building office and an inspection when it's finished, so ask your contractor whether that has been arranged.
