Why Fuse Service
Why Choose Fuse Service for Your Mini-Split Replacement?
Licensed EPA-Certified Technicians
Every mini-split installation is handled by a licensed, certified technician, not a subcontractor. Correct sizing on the first visit keeps your system running efficiently instead of turning on and off every few minutes.
Same-Day Availability
Seattle doesn’t get many hot stretches, and they don’t last long. Book a same-day consultation and we’ll bump you up the schedule, so the system’s in and running before the next heat wave instead of during it.
Upfront Pricing — No Surprises
You’ll receive a detailed written estimate before any work begins. The price covers equipment, labor, refrigerant lines, and electrical connections. What we quote is what you pay.
Up to 12-Year Equipment Warranty
Our mini-split installations come with up to a 12-year parts and labor warranty. If any component fails after installation, we return and resolve it — no service call fee, no conditions.

Benefits of a Ductless Mini-Split System
No Ductwork Required
Mini-splits are ideal for homes without existing ductwork — older Seattle houses, additions, converted garages, and ADUs. Installation is clean and non-invasive: one small wall penetration per zone.
Zone-by-Zone Control
Each indoor unit operates independently. Heat the bedroom, cool the living room, turn off what’s not in use. Multi-zone systems eliminate the waste of conditioning empty rooms.
Heating & Cooling in One System
Modern mini-splits are heat pumps — they provide efficient heating down to 5°F outside. In Seattle’s mild climate, a mini-split can replace both your AC and supplemental electric heating.
High Energy Efficiency
Ductless systems avoid the 20–30% energy loss common in forced-air duct systems. Combined with high SEER2 ratings, they consistently deliver lower monthly utility bills.
Whisper-Quiet Operation
Indoor units operate at 19–26 dB — quieter than a library. Inverter-driven compressors modulate output gradually instead of switching on and off, eliminating the noise spikes of traditional systems.
Fast Installation, Minimal Disruption
A single-zone mini-split installation typically takes 3–5 hours. Multi-zone systems are usually complete in one day. No major construction, no drywall work, no days of downtime.
AC Brands We are Installetion
We install ductless systems from the brands that lead the industry in reliability, efficiency, and warranty coverage. All equipment comes with manufacturer warranties backed by our own labor guarantee.
Areas We Serve
Fuse Service installs ductless mini-split systems across King County and Snohomish County. Our technicians know local permitting requirements, building codes, and the specific comfort challenges of Pacific Northwest homes — from craftsman bungalows to new construction.
