A system that runs most of the year

Heat runs September through June here, ten months a year. Winter nights average 33°F, so whatever you install will be lighting or running on most days, not just during cold snaps. Summers stay mild, afternoons around 75°F, so the cooling side of a new system carries a much lighter load than the heating side.

Most homes here heat with electricity, which means a power outage can mean no heat. Lane County has seen 4 winter storms and 13 damaging wind events over the past ten years, and 20% of Oregon households went at least 24 hours without power in 2024. That is worth thinking about when you decide what to install and how it holds up when the power goes out.

Oregon requires HVAC contractors to hold a state license.

Oregon's Construction Contractors Board licenses the contractor, not the job. That means the state has tested the business and keeps it on record, but the license covers the company generally rather than signing off on any one installation. Work under $1,000 falls outside the licensing requirement, but a full heating and cooling system install runs well past that line, so the contractor doing this job needs to be licensed.

The license is what puts a record behind the business, but it is not the only check on this job. In most cities and counties, a system installation like this needs a permit from the local building office and an inspection once the work is done. That inspection is what confirms the gas connections and wiring were done right, since a bad connection is the part of this job that can actually hurt someone.

When should I replace my HVAC system?
Once your furnace or air conditioner needs frequent repairs, or the repairs cost more than makes sense for its age, start planning a replacement rather than waiting for it to fail. Homes here need heat from September through June, so a furnace that quits is not a small inconvenience, and winter nights average 33°F. If yours struggles to keep up on the coldest nights, or your energy bills have crept up with no clear reason, have a contractor look at it before it fails outright.
Should I replace my furnace and air conditioner at the same time?
If both are old, replacing them together is usually worth considering, but it depends on the condition of each one. A furnace and air conditioner installed at the same time are matched to work together, which avoids problems that can show up when a new unit is paired with an old one. That said, if one system still has years of life left, there is no rule that says you must replace both at once. A contractor can look at the age and condition of each and tell you what makes sense for 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 ducts, gas line or electrical circuit and refrigerant lines as needed. They test the system to make sure it runs correctly, check airflow, and confirm everything is sealed and vented properly. In most cities and counties this work needs a permit from the local building office, and an inspector checks the job once it is done. The exact steps and timing depend on the equipment and your house, so a contractor will walk you through what your installation involves.
