Why Fuse Service
Why Choose Fuse Service for Your
Mini-Split Replacement?
Licensed & EPA-Certified Technicians
Every mini-split replacement is performed by a licensed, bonded, and EPA‑certified HVAC technician. We handle all refrigerant recovery according to Washington State code — safely and legally.
Same-Day Availability
We offer free in-home estimates with same-day scheduling across King County and Snohomish county. When your old mini-split fails in the middle of a Seattle summer, we move fast.
Upfront Pricing — No Surprises
You’ll get a clear written estimate before any work begins. The quote covers removal of the old system, the new equipment, installation, and commissioning. The price we quote is the price you pay.
3-Year Labor + Up to 12-Year Parts
As an authorized dealer of leading HVAC brands, we provide manufacturer parts warranties of up to 12 years on equipment and back every installation with a 3-year labor warranty of our own. Fuse Care 5-year and 10-year labor coverage is available as an optional paid upgrade.

Free In-Home Assessment
Every mini-split replacement starts with a visit: one of our certified technicians evaluates your existing mini-split system, room layout, and specific comfort needs. We assess the number of zones required, BTU requirements per room, and the best mounting locations for the new indoor air handlers.

System Selection & Right-Sizing
We help you choose from leading brands — Mitsubishi, Daikin, Carrier, Trane, and others — selecting the right BTU capacity, SEER rating, and configuration (single-zone or multi-zone) for your Seattle-area home or business. We present a clear, written quote with no hidden costs.

Safe Decommissioning & Removal
We recover the refrigerant from the old system to EPA standards, disconnect the indoor and outdoor units, and haul the old equipment away for recycling.

Precision Installation
During the mini-split replacement we mount the new indoor air handler(s), install the outdoor condenser unit on a level pad or wall bracket, run new refrigerant line sets and communication wiring, and make all electrical connections to code. Proper line set sizing and flare fittings ensure a leak-free system.

System Commissioning & Walkthrough
After the mini-split replacement, we charge the system with the correct refrigerant amount, verify operating pressures, test all zones for proper airflow and temperature control, and program your remote or smart thermostat. We walk you through operation, filters, and maintenance best practices.
to a New Mini-Split
Modern mini-split systems are dramatically more efficient, quieter, and smarter than units from 10+ years ago.
Your System is 10–15+ Years Old
The average mini-split lasts 15–20 years with proper maintenance. Beyond 10–12 years, efficiency degrades and replacement parts become scarce.
Rising Energy Bills with No Explanation
If your usage hasn’t changed but the bills keep climbing, the system is losing efficiency. Worn compressors and aging inverter boards use more power to deliver the same comfort.
Frequent or Expensive Repairs
Follow the “5,000 rule”: if the repair cost × system age exceeds $5,000, replacement is the smarter investment. Compressor failures, refrigerant leaks, and PCB board failures on older systems often signal the end of useful life.
Inconsistent Temperatures & Poor Performance
Struggling to reach set temperature, rooms that stay hot or cold, unusual noises, or ice buildup on the outdoor unit are all signs that the system can no longer perform as intended.
R-22 Refrigerant System
Mini-splits manufactured before 2010 may use R-22 (Freon), which is no longer produced and extremely expensive to source. Replacing it with a current R-32 or R-454B system eliminates that cost.
Areas We Serve
Fuse Service replaces ductless mini-split systems across King and Snohomish County. Every mini-split replacement starts with a free in-home visit, and you get a written price before any work is scheduled.
