Tacoma Weather and HVAC Load
Tacoma logs 4,332 heating degree days and 211 cooling degree days in a normal year, based on the closest NOAA weather station. Heating is the bigger job here, and furnaces and heat pumps in Tacoma put in far more hours than the air conditioner. Summer heat stays mild, with 90°F days almost unheard of, while a normal year brings 27 nights at or below freezing. Snowfall averages about 6 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 | 4,332 |

| Nights at or below 32°F | 27 |

Tacoma Housing Stock
Census figures put the median build year in Tacoma at 1967, so a typical house here has about 59 years on it. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. About 52,000 households here own their home, 56.5% of the occupied total. The median home value is $454,600, and median household income is $83,857. We use both figures to adjust labor and pricing for this page.
NOAA's Storm Events Database shows no hail or damaging-wind days for Pierce County from 2020 through 2025, so storm damage to outdoor units is rare here.
When It Makes Sense
- The house heats with electric baseboard, oil or propane
- There's no natural gas service on your street
- Your AC needs replacing, and you'd like cheaper heat at the same time
What Moves the Price
- A ducted system or a ductless mini-split
- Backup heat, either electric strips or a gas furnace (dual-fuel)
- Variable-speed (inverter) or single-stage compressor
- Electrical panel capacity and wiring
- Size in tons, and whether the unit is cold-climate rated
We raised the national figures about 18% for Tacoma 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.
What the Quote Should Cover
- Commissioning and warranty registration
- Thermostat setup and backup heat settings
- The outdoor heat pump and an indoor air handler or coil
- Line set, drain and electrical hookups
- A load calculation and equipment selection
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 Tacoma 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
- Make sure the installer sized the system for your heating load, not only cooling.
- Where winters get cold, ask for a model on the NEEP cold-climate list.
- Ask your electric utility and state energy office what heat pump rebates are open right now.

Heat Pump Installation Questions from Tacoma Homeowners
How much is heat pump installation in Tacoma?
Plan on $6,500 to $15,900, with most jobs near $11,700. Equipment efficiency, house size and the condition of the ducts and wiring decide where your quote falls.
When is the best time to schedule heat pump installation in Tacoma?
Between late spring and early fall. Tacoma averages 27 freezing nights a year, and heating calls spike from November through February.
How long does a heat pump last?
Usually 12 to 15 years. A heat pump runs year-round, so it needs maintenance twice a year rather than once.
Do heat pumps work in cold weather?
Yes. Cold-climate heat pumps keep making heat well below 0°F. They lose efficiency as it gets colder, so many homes in cold regions keep backup heat.
