What shapes your quote
These factors decide where your job lands in the range — and we walk you through each one on the written quote.
- Age and brand of existing equipment, since parts for older Trane, Carrier, or Rheem units can take longer to source
- Attic, crawlspace, or tight closet access, common in older Seattle and Everett homes built before modern HVAC layouts
- Ductwork condition, since many homes built before 1990 need sealing or resizing before a new system performs correctly
- Electrical panel capacity, especially for heat pump or ductless conversions in homes served by PSE or Snohomish County PUD

Straight answers
HVAC Services questions we hear most
How much does HVAC service cost in Greater Seattle?
Most jobs start from $129 for a basic diagnostic visit, with repair or installation pricing depending on the system and parts needed. You get a written estimate before any work begins, so there are no surprises once the job is underway.
Do I need a heat pump or a furnace in Western Washington?
Many King and Snohomish county homes now run on heat pumps since local winters rarely drop far below freezing, keeping them efficient year-round. Homes with existing gas lines sometimes keep a furnace as backup. We look at your insulation, ductwork, and utility rates before recommending either option.
How often should I schedule HVAC maintenance?
A yearly tune-up in early fall, before heating season starts, catches worn parts, dirty filters, and refrigerant issues early. Regular maintenance also helps avoid a breakdown during the first cold snap of the year, when service calls are hardest to schedule quickly.
