A system built to run most of the year
Centralia needs heat from September through June, ten months a year. Winter nights average 31°F through December to February, so the system spends most of its life running, not sitting idle waiting for a cold snap.
Summer afternoons average a mild 72°F, so cooling asks little of it here. Heat is the real job, and most homes in the area already run on electric heat. A new system installed today has to meet the federal minimum efficiency rating for its type, so ask what rating the equipment carries before it goes in.

Washington requires contractors to register with the state.
That registration means the contractor's business is on file with the Department of Labor and Industries. It is not a license. There is no trade exam behind it, so the number on their truck tells you they are on record with the state, not that anyone checked their skill.
For a job like this, the protection comes from the permit, not the registration. In most cities and counties, installing a furnace, air conditioner or heat pump needs a permit from the local building office, and the work gets an inspection once it's done. That inspection is what checks the gas connections, the wiring and the refrigerant lines.

- When should I replace my HVAC system?
- Replace it when repairs get frequent, when it can't keep the house at 31°F outside without struggling, or when it's old enough that parts are wearing out one after another. Most systems last a couple decades, but the number that matters more is how often you're calling for repairs in a single season. Here, the furnace runs from September through June, so it's doing most of the work year round and wearing accordingly. If a contractor is telling you the same part is failing again, or the repair costs are climbing close to what a new system would run, that's the point to stop patching and replace it.
- Should I replace my furnace and air conditioner at the same time?
- Homes here don't need cooling, so most systems in this area are furnace only, with no air conditioner to consider. If your setup does include one, replacing both together makes sense when they're the same age and both nearing the end of their life, since a contractor is already on site to open up the ductwork and connections. But if the furnace is failing and the air conditioner still has years left, there's no reason to replace a working unit just to match it.
- What happens during an HVAC installation?
- A contractor removes the old furnace, sets the new one, and connects it to the existing ductwork, gas line or electrical circuit, and venting. They'll check that the vent hood and flue are sized right for the new unit, since venting requirements change between models. Once it's running, they test the ignition, the airflow through the ducts, and the thermostat control before calling the job done. Most cities and counties require a permit for this kind of replacement, along with an inspection afterward, so ask whether that's included in the scope of work. A contractor can walk you through the specifics for your house and give you a price for the job.
