Why does only one of my indoor heads stop working?
Each head has its own fan motor, sensors and control board, plus wiring back to the outdoor unit. A single dead zone usually points to that head or its communication line rather than the whole system, which is good news for the repair.
What does the blinking light on my mini-split mean?
It is an error code, and the pattern matters. Count the blinks and note whether the timer or operation light is involved, then tell us when you call. That code narrows the diagnosis before we open anything up.
Can a leaking indoor head be repaired, or does it need replacing?
Usually repaired. Most leaks come from a blocked condensate drain or a filthy blower wheel throwing water past the pan. We clear the drain, clean the coil and blower, and confirm the line still drains under load.
Why does my mini-split ice up outside in winter?
Wet, cold weather across the region loads outdoor coils with frost, and the unit is designed to defrost periodically. Persistent ice means the defrost cycle, a sensor or the refrigerant charge needs attention. Do not chip at the ice.
How soon can you get to my Issaquah home?
Call or book online and we will give you the next available window rather than a vague promise. During the first real heat stretch of summer and after the first hard cold snap, AC repair and heating repair calls stack up across the region, so booking early in the day helps. If you smell gas or suspect carbon monoxide, leave the house first, call 911 or your gas utility, then call us.
How it works
- Step 1
Tell us the symptom
Call or fill in the quote form. Describe the noise, the smell, the temperature, and when it started. That detail helps us bring the right parts and gives you an honest idea of the visit ahead.
- Step 2
We diagnose on site
A technician checks the thermostat, airflow, electrical connections, refrigerant behaviour and the outdoor unit. We tell you what failed and why, in plain language, before anyone reaches for a part or a price.
- Step 3
You choose the repair
We lay out the fix, any parts on order, and what happens if you wait. Once you agree, we do the work and confirm the system holds temperature before we pack up and leave.

Why homeowners call us
- Heat pumps are our normalIn this region heat pumps outnumber furnaces, so defrost boards, reversing valves and short cycling in wet weather are everyday work for us. We know how these systems behave in a cold December rain, not just on a test bench.
- Wet winter defrost problemsIce on the outdoor coil, a unit that runs and runs without warming the house, puddles that refreeze under the pad. We trace whether it is a sensor, a stuck valve, drainage, or airflow, then fix the actual cause.
- Filtration after smoke seasonWildfire smoke turned indoor air quality into a real conversation here. We look at filter fit, return sizing and IAQ options that your blower can actually push air through, rather than choking the system with the wrong media.
- We explain before we chargeYou get the diagnosis, the options and the trade-offs before work starts. If a repair is not worth it on an old system, we say so. No pressure, no jargon dumped on you at the door.
