Get answers to common questions about hvac services in Seattle, Washington.
Seattle's high humidity and mild temperatures create a unique challenge, primarily promoting mold and mildew growth within your system, especially in the air handler and ductwork. This makes annual preventative maintenance, including coil cleaning and ensuring proper drainage, critical to maintain air quality and system efficiency. Furthermore, our long, cool heating season means your furnace or heat pump works extensively, so regular fall check-ups are more important than in many other climates.
For a standard efficiency replacement, costs typically range from $5,000 to $12,000+, with high-efficiency heat pump systems often on the higher end due to their dual heating and cooling capability. Crucially, Seattle homeowners should check for current rebates from Seattle City Light and Puget Sound Energy, as well as federal tax credits, which can significantly offset the cost of upgrading to an energy-efficient heat pump, a popular choice for our climate.
The absolute best times are during the "shoulder seasons"—late spring (April-May) or early fall (September-October). Scheduling outside of the peak summer heat waves and the first cold snaps of winter ensures greater technician availability, often shorter wait times, and potential off-season promotional pricing. Avoid calling during a sudden July heatwave or November cold front, as emergency calls will cause significant delays for non-urgent service.
Always verify the contractor is both Washington State Registered (with a "REG" number) and bonded/insured, which is a legal requirement. Look for companies with specific experience installing and servicing heat pumps, as they are the dominant high-efficiency choice here. Finally, check for strong local reviews mentioning punctuality, clear communication, and knowledge of local utility rebate programs to ensure a smooth process.
This is very common and often normal. Seattle's winter temperatures frequently sit in the 30s and 40s—the ideal operating range for a heat pump, which provides heat efficiently by moving air rather than generating it like a furnace. However, if it's running non-stop without adequately heating your home, it could indicate an issue like low refrigerant, a failing component, or that the system is undersized for our cooler, damp cold; a professional evaluation is recommended.
