Ten months of heat, almost no break
Ellensburg needs heat from September through June. Winter nights average 23°F, cold enough that a furnace or heat pump runs long hours to hold a house steady. Summer afternoons average just 75°F, mild enough that cooling barely factors into the choice.
59.9% of homes here heat with electricity, so a power outage means no heat too. Kittitas County has seen 26 winter storms and 3 damaging wind events over the past ten years, and across Washington 23% of households lost power for at least 24 hours in 2024. A new system installed here should be sized for the cold nights it will run through most of the year, with a plan for what happens if the power goes with them.

Washington requires contractors to register with the state.
That registration puts the business on file with the Department of Labor and Industries. There is no trade exam behind it, so nobody from the state has tested this contractor's work. It tells you the business is on record, not that the installation itself was checked.
For a job installing a furnace, air conditioner or heat pump, that check comes from the local building office instead. In most cities and counties in Washington, this kind of installation needs a permit before the work starts and an inspection once it is done, and it is that inspection, not the registration, that confirms the work was done right.

- When should I replace my HVAC system?
- Replace it when repairs start costing more than they're worth, or when the unit is old enough that another breakdown seems likely. Watch for signs like uneven heating, rising bills, or a repair technician telling you parts are hard to find. Homes here need heat from September through June, so a furnace that fails in the middle of that stretch is a much bigger problem than one that fails in summer. It's worth replacing an aging system before it quits on a cold night rather than after.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, it usually makes sense to do them together. A furnace and air conditioner installed at the same time are matched to work as one system, and replacing them together lets the contractor handle the ductwork and wiring in a single job. If one unit still has years of life left, there's no reason to replace it early just to match the other. A contractor can look at the age and condition of both and tell you honestly whether pairing them makes sense for your house.
- What happens during an HVAC installation?
- A contractor starts by removing the old equipment, then sets the new furnace, air conditioner or heat pump in place and connects it to the existing ductwork, gas line or electrical circuit. They check the refrigerant lines, wiring and venting, then test the system to make sure it heats and cools the way it's supposed to. In most cities and counties, this work needs a permit from the local building office, and an inspector checks the job once it's done. That inspection is there to confirm the system is safe and installed correctly before you're relying on it.
