Mini-Split Repair — Book a Visit Today
We repair ductless mini-splits and multi-zone systems for homeowners across Illinois, Indiana, Kentucky, Ohio, Tennessee and West Virginia, and you can book a visit any day we are open. Most failures we find are one of a handful of things: a clogged blower wheel or filter screen in the indoor head, a plugged condensate drain that trips the unit off, a failed outdoor fan motor or control board, low refrigerant charge from a loose flare connection, or a remote and thermostat setting fighting the system. A visit starts with the head that is misbehaving, then the outdoor unit, then the line set and electrical connections. We tell you what failed and what the repair involves before we touch it. Call us or send a message with your model and what you are seeing.

The mini-split symptoms we hear most
- One room is freezing and the other three are fine Zone control, indoor unit board or a refrigerant distribution fault on a multi-zone system
- Water is dripping down the wall under the indoor head Blocked condensate drain, sagging drain line or a frozen coil thawing
- The indoor unit blows but the air is not cold Low refrigerant charge, dirty coil or an outdoor compressor and fan problem
- Blinking lights on the head and nothing happens Stored error code from a sensor, communication wire or control board fault
- Musty smell every time the mini-split starts up Biological growth on the blower wheel and evaporator coil, an IAQ and cleaning issue
Whether you call it mini-split repair or ductless AC repair, the work is identical and so is the quote you approve first.
Safe things to check first
Worth a look before you call — sometimes it saves you the visit.
- 1Check the thermostat or remote: fresh batteries, mode set to cool or heat rather than fan or dry, and a setpoint that actually calls for the system to run.
- 2Look at your breaker panel and any outdoor disconnect switch for a tripped breaker, and reset it once. If it trips again, stop and call us.
- 3Pull the washable filter screens out of each indoor head. If they are grey with dust, rinse them, dry them fully and reseat them.
- 4Clear leaves, grass clippings, mulch and stored items away from the outdoor unit so it has open space on all sides and above.

Can a mini-split head be repaired, or does the whole system have to be replaced?
Most of the time the head itself is repairable. Blower motors, control boards, sensors and drain pans are replaceable parts. We only talk about replacement when the outdoor compressor has failed on an older system or parts are no longer available for that model.
Why does only one zone of my multi-zone system stop working?
Multi-zone outdoor units use an electronic valve for each indoor head. When one zone quits and the rest keep running, that valve, the communication wiring to that head, or the head's own control board is usually the cause. We test each zone separately.
My mini-split is icing up outside in winter. Is that normal?
A light coat of frost is normal in heat mode, and the system should shed it during a defrost cycle. Solid ice that never clears points to a defrost sensor, reversing valve or charge problem, and that is worth a service call before it worsens.
How often should mini-splits be cleaned?
Once a year for most homes, more if you have pets or run the system year round. Rinsing the filter screens is homeowner work. Deep cleaning the blower wheel and evaporator coil takes a proper wash kit and is part of what we do on a service visit.
What do the blinking lights and error codes mean?
Each manufacturer uses its own code list, and the pattern tells us which sensor or circuit reported a fault. Write down the number of blinks or the code shown, then give it to us when you call. It shortens the diagnosis considerably.
The remote is dead. Is that my whole problem?
Sometimes, yes. Try fresh batteries first. If the head still ignores the remote, the infrared receiver in the indoor unit or its control board may have failed. Many units also have a small manual button on the housing that confirms whether the unit itself still runs.
How it works
- Step 1
Tell us the symptom
Call or fill in the quote form. We ask what changed, when it started, and what the thermostat reads. That short conversation tells us whether you need a visit today or tomorrow morning.
- Step 2
We diagnose on site
A technician checks the thermostat, the electrical side, airflow through the filter and ducts, and the equipment itself. We find the actual cause instead of swapping parts and hoping the noise goes away.
- Step 3
You decide before we work
We explain what failed, what the repair involves, and what we would do if it were our own house. Nothing gets replaced until you say go. Then we test the system before leaving.

Why homeowners call us
- Old houses and new onesWe are used to century-old homes with retrofitted ductwork and 1970s subdivisions with original returns. Tight crawl spaces, low basement headroom and odd attic runs are normal parts of the day for us, not surprises that stall the job.
- Built for the swingsHumid summers push AC systems hard and January freezes expose weak igniters and cracked flues. We repair for both extremes across the region, so the fix holds when the weather turns instead of failing the first hard week.
- Air conditioning and heating bothAir conditioner repair in July, heating repair in January, and the IAQ and airflow problems that hide in between. One crew that knows how your cooling and heating share the same blower and the same duct system.
- Plain talk, no pressureWe tell you when a repair makes sense and when replacement is the honest answer. No scare tactics about your BTU load, no upsell scripts. You get the condition of the system and a clear next step.

- Straight answersIf a system is not worth repairing, we say so, often right on the phone.
