Over 174, verified 5-star customer reviews
Utility-verified for efficiency and workmanship
Parts and labor covered on replacements, if needed
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.

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.
Cascadia Comfort came to service our HVAC system as well as to provide estimates for some work we would like done. Scheduling was a breeze and when I had to cancel the original appointment due to travel, they were very accommodating. Our technician called when he was an hour out and arrived promptly. He was very informative and thorough as we went through the scope of work. The maintenance on our furnace indicated the need for replacing a part, and the technician explained not only the function of that part, but also showed me the multimeter reading. He had the part on the truck and was able to take care if it immediately. We are very happy to have had Cascadia Comfort to provide the maintenance. We would definitely have them perform this work in the future. It will take a few days to get the estimate back for additional work, so I am not able to comment on that pricing, but the maintenance and repair price and part seemed reasonable!Posted on Google Lea Ellis Very friendly and helpful teamPosted on Google Sai Rahul Kasula We recently booked an AC and furnace tune-up through Groupon with Cascadia Comfort, and we had a great experience from start to finish. Kyle was very professional, knowledgeable, and courteous throughout the service. His communication was top-notch, and he took the time to explain everything clearly and answer our questions. The entire process was smooth, efficient, and hassle-free. We really appreciated the excellent customer service and attention to detail. We would definitely recommend Cascadia Comfort to anyone looking for reliable HVAC service and will gladly use them again in the future.Posted on Google Manali Great service, friendly, timely.Posted on Google Jay Anderson They are the best! Our HVAC system was leaking, and Riley from the company came to our home the very same day. He was extremely knowledgeable, quickly identified the issue, and shared many helpful tips on how to maintain our HVAC system for the long term. We really appreciated getting a same-day appointment, which made the whole experience even better. The team was professional, courteous, and efficient from start to finish. I highly recommend them!Posted on Google Aman Mahajan Regis came out for regular maintenance on my heat pump and furnace and he was awesome! He took the time to check everything in detail and then went over what he found with me. He was patient and answered all of the many questions I peppered him with. We'll definitely call Cascadia Comfort again in the future.Posted on Google Nate Regis was wonderful and professional. He left us with a functioning AC after less than 30 min after a previous tech couldn’t fix it. Highly recommend!Posted on Google Alicia Mangubat-Medina Great company! Highly recommend. Super friendly technician, Regis, was quick, thorough, didn't leave any mess, very communicative, and punctual. Was very respectful of our house, efficient, and made sure everything was good to go and my questions answered before leaving. Definitely will use them again!Posted on Google Stephanie Reading

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.
