A system that has to carry most of the year
Multnomah County asks for heat nine months out of the year, October through June, on nights that average 34°F in the dead of winter. That is not a system that gets a break. It runs and cycles and runs again for most of the year, and a new furnace or heat pump here needs to be sized and installed to hold up to that kind of use, not just handle a cold snap now and then.
Summer asks less. Afternoons average 76°F over a single month of real cooling need. But close to half the homes in the county heat with electricity, so the equipment doing that work matters when the power goes out. This area has seen 29 winter storms and 17 damaging wind events over the past ten years, and a fifth of Oregon households lost power for at least 24 hours in 2024. A new system here should be matched to what the winters demand and to what happens when the power does not stay on.

Oregon requires HVAC contractors to hold a state license.
The Construction Contractors Board licenses HVAC contractors in Oregon, which means the state has tested this contractor and keeps them on record. That license belongs to the contractor, not to any single job. Work under $1,000 is the one case where Oregon does not require a licensed contractor, and a heating and cooling installation runs well past that.
The license tells you the contractor is who the state says they are. It does not cover what happens once the work starts. In most cities and counties, replacing a furnace, air conditioner or heat pump needs a permit from the local building office, and the finished job gets an inspection.

- When should I replace my HVAC system?
- Replace it when repairs keep coming back, when the system is old, or when it can no longer keep the house at a steady temperature. A contractor can look at what keeps failing and tell you honestly whether it's worth fixing again or not. Homes here need heat from October through June, so a furnace that struggles is not something to put off. If you're weighing a repair against replacement, ask the contractor what's actually wearing out and why.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, replacing them together is often the better move, but it depends on the condition of each one. A furnace and air conditioner installed years apart may not be matched well, and that mismatch can wear on whichever one is newer. Cooling season here is short, just August, while heat runs from October through June, so the furnace carries most of the load and its condition matters more. A contractor can check both and tell you honestly whether one still has real life left.
- 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 the ducts, gas or electrical lines, and condensate drain as needed. Once it's running, they test it, check refrigerant levels and airflow, and walk through the controls with you. In most cities and counties this work needs a permit from the local building office, with an inspection after the job is done. That inspection confirms the work was done to code, so it's worth asking your contractor how they handle it.
