Added a ductless system to a century-old house and now it blinks, drips or goes cold? We handle mini-split repair in Snohomish for most brands, Mitsubishi included, and you hear the price before any work begins.



Plenty of Snohomish homes began life with no ducts at all, so ductless heads became the retrofit of choice. Long refrigerant runs through plaster walls and valley dampness create their own set of faults.
Long, shallow condensate runs in old framing sag and clog. Water then spills from the bottom of the head onto a wall or windowsill.
A communication fault between indoor and outdoor units often hides behind a flashing light. Jot down the pattern before you reset anything.
Dirty coils, a buried outdoor unit or a head asked to heat too many rooms all cut output when the thermometer drops toward freezing.
Low airflow or a slow refrigerant leak turns the indoor coil to ice during cooling. Switch to fan only and let it thaw.
Damp valley air feeds grime on the blower wheel. A true cleaning means pulling the wheel, not just rinsing the filter.
Dead batteries, a Wi-Fi adapter that lost its network after a router swap, or a failed receiver board can look alike from the couch.
Rinsing a filter is fine. Opening the head, spraying cleaner into it or hosing down the outdoor coil is not. If the breaker trips twice, leave it off and call us.
We keep the process simple and repeatable. On the money side, a visit to your home goes like this:
We trace the fault, show you what failed and explain the options. The fee is waived when we finish the repair the same day.
The repair price is quoted up front. Nothing gets opened, ordered or replaced until you approve the number.
For a larger fix, Wisetack spreads the cost across monthly payments, with 0% interest for qualified buyers.
Not sure it is worth fixing? We will say so plainly. If a sensor is the culprit, a small repair beats a new system.
Our shop is a short drive up SR 9 in Lake Stevens, which is why same-day visits are usually possible.
Mitsubishi, Fujitsu, Daikin, LG and more. We are a Mitsubishi Electric Diamond Contractor, but your unit does not need that badge.
We chase the actual fault first. A new system only comes up when the old one truly cannot be saved.
Most mini-splits we see in Snohomish are worth fixing. A bad sensor, drain or flare fitting rarely justifies a whole new system.
Replacement starts to make sense when the compressor has failed on an older outdoor unit, when the system is discontinued and boards are hard to find, or when one head was always asked to heat far more space than it was sized for. We will lay out both paths with real numbers, then leave the decision to you.
A yearly cleaning ahead of fall keeps small faults from turning into winter breakdowns, and it is far cheaper than an emergency call in January.

Yes. We repair most brands and models, whoever put them in. Bring us the model number if you have it, and we will start from there.
The usual cause is a clogged or sagging drain line, or a failed condensate pump. Turn the unit off, catch the water and call us before the wall or floor takes damage.
Yes. Repairs happen on equipment already in place, so we work around your finishes and keep the visit tidy. Questions about changes to the exterior are best put to the City first.
We answer 24/7, and same-day visits are usually available. We never promise exact arrival times, but you will get a clear window when you call.
Yes, brief steam and a whoosh mean the unit is melting frost, which is defrost mode. Call if ice builds up and never clears, or the unit stops heating.
Yes, through our S.M.A.R.T. Maintenance plans. Mini-splits count as heat pumps, so they are covered under the Heating and Cooling Plan.
