Ten months of heating, most of it on electricity
Longview needs heat from September through June. That is ten months a year the system is working, with only a short stretch in summer when it can rest. Winter nights average 33°F from December through February, so a new furnace or heat pump has to hold up to months of steady runtime, not just a few cold weeks.
Most homes here heat with electricity, so the system and the power feeding it are tied together. Cowlitz County has seen six winter storms and five damaging wind events over the past ten years, and statewide, almost a quarter of households lost power for at least a day in 2024. Whatever gets installed should be sized and set up for a county where the lights and the heat can go out at the same time.

Washington requires contractors to register with the state.
Registration puts the business on file with the Department of Labor and Industries. There is no trade exam behind it, so it does not test whether the crew doing your installation knows the work. It tells you the business is on record. It does not tell you the job will be done right.
For this job, that check comes from the local building office instead. In most cities and counties, installing a new furnace, air conditioner or heat pump calls for a permit, and an inspector looks at the finished work once it is done. That inspection, not the state registration, is what stands behind the installation here.

- When should I replace my HVAC system?
- Replace it when it's failing more than once a season or when it can't keep up on the coldest nights anymore. With winter lows around 33°F here, a furnace that struggles in December is only going to get worse as winter goes on. Age matters too. A furnace working hard for 10 months of the year, September through June, wears down faster than one that only runs a few months. If yours is old and the repair bills keep coming, that's your answer.
- Should I replace my furnace and air conditioner at the same time?
- Homes here run on heat almost year round and don't need cooling at all, so this isn't really a two-system question for most houses in Longview. If your home does have central air alongside the furnace, replacing both together only makes sense when both are actually worn out. A contractor can look at the age and condition of each and tell you whether one or both need to go.
- What happens during an HVAC installation?
- A contractor removes the old furnace and any related equipment, sets the new one, and connects it to the ductwork, gas or electric line, and venting. Once it's running, they test it, check the airflow, and make sure it cycles the way it should. Most cities and counties require a permit for this work and an inspection when it's done, so expect that as part of the process. Since most homes here heat with electricity, a lot of installations also involve checking that the electrical connection can handle the new unit.
