All brands serviced. Mitsubishi-level training standard.
Flexible plans, approval in minutes
No power, no response from the head or the outdoor unit, even after a reset.
Running but not actually cooling or heating the room anymore.
Air is cool, but barely reaching the vents.
You’ve called us (or someone else) more than once this year for the same unit.
Clicking, buzzing, or grinding from the head or outdoor compressor.
Same usage, but the power bill keeps climbing every month.
Every replacement starts with a full assessment, not a guess. Here’s what happens from quote to walkthrough.
We check your current unit’s condition, sizing, refrigerant type, and how well it’s actually matched to the room before recommending anything.
You’ll see 2-3 system options with real pricing, no vague ranges. We explain the trade-offs so you can pick what fits your home and budget.
We size the new system to your room, not just swap in whatever matches the old one. Wrong sizing is the #1 reason mini-splits underperform.
Every install includes the required mechanical and electrical permits, pulled and paid for as part of your quote. No surprise fees, and no unpermitted work that could come back to bite you at resale or with your insurance.
Old unit removed, new indoor and outdoor units installed, lines set, and system charged to manufacturer spec.
We run the system through a full cycle, confirm performance, and walk you through the new controls before we leave.
Every Mitsubishi system we install is backed by a 10-year parts and labor warranty when registered through Cascadia Comfort. If something goes wrong that isn’t your fault, it’s on us, not you.
You’re not the first homeowner to trust us with a replacement. We’ve earned over 175 verified 5-star reviews from homeowners across Mill Creek, Bothell, Lynnwood, and beyond.
We install Mitsubishi on almost every replacement we do. Not because it’s the only good brand, but because it’s the one we trust most in Pacific Northwest winters.
HOW IT COMPARES:
| Mitsubishi | Daikin | Fujitsu | |
|---|---|---|---|
| Cold-climate performance | Best in class (Hyper-Heat) | Strong | Good |
| Parts availability (Seattle area) | Excellent | Good | Fair |
| Warranty (with certified install) | Up to 12 years | Up to 12 years | Up to 12 years |
| Local contractor support | Widely serviced | Widely serviced | Fewer certified installers |
WHY IT MATTERS FOR YOUR INSTALL:
Hyper-Heat technology holds performance down to -13°F. Most Puget Sound winters never test this, but the handful of cold snaps we do get are exactly when a lesser system struggles.
Parts are easier to source here. Mitsubishi has strong distribution in the Seattle area, so if something does need service down the line, we’re not waiting on a special order.
We’re factory-trained on Mitsubishi specifically. That means faster, more accurate installs and full support on warranty claims.
Every mini-split can be patched. The question is whether patching it is actually the smart move. Here’s how we make that call with homeowners:
REPLACEMENT IS WORTH CONSIDERING IF:
REPAIR USUALLY MAKES SENSE IF:
We’ll always tell you straight which category you’re in. If a repair is the right call, that’s what we’ll recommend.
ASSESS
1. Current system inspection — Check the age, condition, and refrigerant type of your existing unit.
2. Room and load evaluation — Measure the space, insulation, sun exposure, and window count to calculate proper sizing.
3. Electrical and lineset check — Confirm your home’s electrical capacity and whether existing line sets can be reused or need replacing.
4. Placement review — Evaluate indoor head and outdoor unit placement for airflow, noise, and aesthetics.
DECIDE
5. System options presented — We walk through Mitsubishi and Daikin options at different price points, sized correctly for your space.
6. Financing and timeline discussed — You approve the system and we schedule the install.
INSTALL
7. Old system removed — Indoor head, outdoor unit, and old line sets removed and disposed of properly.
8. New system installed — Mounted, wired, and connected per manufacturer spec.
9. Line set and electrical work — New or reused lines set, electrical connections completed and tested.
10. Vacuum and charge — System is vacuum-tested for leaks and charged to exact manufacturer spec.
11. Test and walkthrough — We run a full cycle test and walk you through the new remote/controls before we leave.
Mini-split replacement costs vary based on a few key factors. Here’s what actually moves the number:
Cascadia Comfort isn’t a truck with a phone number. We’re based in Mill Creek and we replace mini-splits throughout Bothell, Lynnwood, Everett, Snohomish, and Lake Stevens every week.
Why local knowledge matters for replacement:
PSE Trade Ally: Utility-verified contractor for Puget Sound Energy customers
Kicking Gas Partner: Helping Snohomish County homeowners access electrification subsidies
We look to provide a free system each year, for local nonprofits, including:
While we work on every type of system, we’re factory-trained on Mitsubishi systems, not generalists who install whatever’s on the truck. This is an exclusive club.
Every quote starts with a real load calculation. No guessing, no one-size-fits-all system.
We know current PSE and Snohomish PUD rebates and file the paperwork so you get the credit.
Founders grew up here. We know what actually holds up through a Puget Sound winter, and a toasty summer, not just what’s cheapest to install.
MINI-SPLIT MAINTENANCE
Keep your new system running efficiently with regular tune-ups. Extend its life and protect your warranty.
ELECTRICAL
Panel upgrades, new circuits, and wiring work to support your mini-split install, done by licensed electricians.
INDOOR AIR QUALITY
Pair your new system with filtration or purification add-ons for cleaner air alongside better heating and cooling.
Most systems are worth repairing if they’re under 8 years old and this is the first real issue. If your system is 10+ years old, on R-22 refrigerant, or you’ve had repeat repairs, replacement usually saves you money long-term. We’ll give you a straight answer on-site, not just an upsell.
Cost depends on the number of zones, system size, and whether existing line sets and electrical can be reused. We’ll give you a clear, itemized quote before any work starts, no vague ranges.
Mitsubishi’s Hyper-Heat systems hold performance in cold snaps better than most alternatives, parts are easy to source in the Seattle area, and our techs are factory-certified on their systems. We’ll install Daikin or another brand if that’s your preference, but Mitsubishi is what we recommend for most homes.
Yes. Mechanical and electrical permits are included in your quote, not billed as an extra. That keeps the install compliant and protects you at resale or with insurance.
Every system we install carries a 10-year parts and labor warranty when registered through Cascadia Comfort. If a covered issue comes up, it’s on us.
Most single-zone replacements are done in a day. Multi-zone systems or jobs that need electrical upgrades can take longer. We’ll give you a specific timeline with your quote.
Yes, we offer flexible plans with approval in minutes. We’ll walk you through options when we present your quote.
