Ductless Mini-Split Repair
Ductless systems are reliable, but they are also different from conventional equipment: inverter-driven compressors, communicating controls, and error codes that require the manufacturer's diagnostic procedure rather than a generic gauge set.
Our technicians are trained on inverter equipment and carry the tools to read fault codes, test communication between indoor and outdoor units, and repair mini-splits properly instead of guessing at parts.

What to Watch For
Common Ductless Problems We Fix
If your mini-split is doing any of the following, it needs service rather than another reset.
Blinking lights or an error code
Each manufacturer uses its own fault codes, and reading them correctly is the fastest path to the actual failure.
Water dripping from the indoor unit
A blocked condensate drain or failed condensate pump — common, and easy to fix before it damages drywall.
Weak airflow or poor cooling
A dirty blower wheel or filter, or a refrigerant charge issue in the line set.
The unit runs but never reaches setpoint
Sensor faults, inverter board problems, or a slow refrigerant leak at a flare connection.
Musty odor from the indoor head
Biological growth on the coil and blower wheel that requires a deep cleaning, not a spray-and-go.
One zone works, others do not
Branch box, valve, or communication wiring issues in multi-zone systems.
How It Works
How We Repair Ductless Systems
- 1
Read the system
We pull fault history, check communication between units, and test sensors and board voltages using the manufacturer's diagnostic sequence.
- 2
Verify the refrigerant circuit
Flare connections are the most common leak point on mini-splits. We pressure test and locate leaks rather than just topping off the charge.
- 3
Flat written quote
You approve the repair price before we start, including honest guidance when a board replacement approaches the cost of new equipment.
- 4
Repair and verify
We complete the repair, deep clean the indoor unit if needed, and confirm performance in both heating and cooling modes.
Pricing
What Affects the Cost
Mini-split repair pricing depends heavily on which part of the system failed.
Component type
Sensors and condensate pumps are inexpensive; inverter and control boards are the costliest common failure.
Parts availability
Major brands stock parts well; off-brand systems sold online can be very difficult to source.
Refrigerant leak repair
Locating and repairing a leak, then evacuating and recharging, takes longer than a simple part swap.
Deep cleaning
Full blower wheel and coil cleaning requires partial disassembly of the indoor head.
Zone count
Multi-zone systems have branch boxes and additional communication paths to test.
