Ten months of the year, your system is working
Winter nights in Chelan County average 22°F from December through February, and homes here need heat from September clear through June. That is ten months of the year your furnace or heat pump is doing something. Summer afternoons stay mild here, averaging 72°F, so cooling is a small part of the job, but a new system still has to be sized and installed for both sides of the year.
Most homes in this area heat with electricity, and the region sees real weather. Chelan County has logged 118 winter storms and 29 damaging wind events over the past ten years, and close to a quarter of Washington households lost power for at least a day in 2024. When a system runs almost all year, the parts that start it and keep it going see a lot of use, and installing it right matters more here than it would somewhere the system gets more rest.

Washington requires contractors to register with the state.
Washington puts contractors on file with the Department of Labor and Industries. That is a business record, not a trade exam. Nobody at the state tests how a contractor sizes a heat pump or sets up a furnace before handing out that registration.
For this job, the check on the work comes from the local building office instead. In most cities and counties, installing a new furnace, air conditioner or heat pump needs a permit before the work starts and an inspection once it is done. That inspection is what catches a bad gas connection or a system that was not put in to code.

- When should I replace my HVAC system?
- Once repairs start happening every year, or one repair costs a large share of what a new system would run, it is time to replace rather than fix again. Age is part of it too, and a furnace here works harder than most, since homes need heat from September through June. If your system needs a repair and is getting older, get a quote for replacement before you pay for another fix.
- Should I replace my furnace and air conditioner at the same time?
- If both units are old, yes, because pairing a new furnace with an old air conditioner often means replacing the second one within a few years anyway. Homes here barely run cooling, summer afternoons average 72°F, so the air conditioner may still have plenty of life left even when the furnace does not. A contractor can look at both units and tell you whether one is close behind the other.
- What happens during an HVAC installation?
- A contractor removes the old furnace or heat pump, sets the new unit, and connects it to your ducts, gas line or electrical circuit and your thermostat. They check the ductwork for leaks or damage while it is open, since sealing problems there now saves trouble later. Once everything is connected, they run the system and test it before calling the job done. Replacing a heating or cooling system here needs a permit from the local building office, and an inspector checks the work afterward.
