Vancouver Weather and HVAC Load
In a normal year, Vancouver racks up 4,400 heating and 399 cooling degree days (NOAA 1991-2020 normals). Heating is the bigger job here, and furnaces and heat pumps in Vancouver put in far more hours than the air conditioner. On average, Vancouver gets 45 freezing nights and 15 days above 90°F per year. Snowfall averages about 4 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 55,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.
| Heating degree days / year | 4,400 |
|---|---|
| Cooling degree days / year | 399 |
| Nights at or below 32°F | 45 |
| Days above 90°F | 15 |
| Average low / high | 44.7°F / 63.2°F |
Vancouver Housing Stock
The median Vancouver home dates to 1987, according to the Census ACS. That makes the typical house about 39 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Owners live in 49.9% of occupied homes, roughly 40,000 households. With a median household income of $78,156 and a median home value of $440,300, local labor rates come out near the national middle in our model.
Between 2020 and 2025, NOAA's Storm Events Database logged 3 days with damaging thunderstorm winds in Clark County. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost. Clark County also had 2 tornado days in that period.
When Replacement Makes Sense

- Both the heating and cooling equipment are 15 years old or more
- An old R-22 AC paired with an aging furnace
What Moves the Price
- Efficiency ratings: SEER2, AFUE and HSPF2
- Equipment sized to the house and climate
- Permits and electrical work
- Thermostat and zoning upgrades
- Furnace plus AC, or heat pump plus air handler
- Duct repair or replacement
We raised the national figures about 16% for Vancouver using local income, home values and the equipment size this climate needs. Real bids can still come in outside the range, so collect three written quotes.

Washington Permits, Efficiency Rules and Rebates
Washington falls in the DOE's North region. New split central air conditioners must meet at least 13.4 SEER2, and heat pumps sold anywhere in the U.S. need 14.3 SEER2 and 7.5 HSPF2. Equipment replacements in Vancouver generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their Washington license or registration number and a certificate of insurance with the quote. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
Before You Hire

- Get one quote for a heat pump system and one for a furnace plus AC.
- Make every bidder quote the same efficiency ratings, or the prices won't compare.
