Fast, Accurate Mini-Split Repair for Zoned Heating & Cooling
When your ductless mini-split stops cooling, heating, or responding to commands, Pack-Timco provides rapid, expert diagnostics designed specifically for high-end homes with multi-zone comfort needs. Mini-splits are precise, variable-speed systems — when they fail, comfort disappears instantly. Our specialists identify the root cause quickly, repair it correctly, and restore stable, efficient operation.
No guesswork, no unnecessary part replacements — just the right repair, done with engineering-level accuracy.
Precision Diagnostics for Ductless Mini-Split Systems
Mini-splits combine refrigeration technology, inverter-driven compressors, sensors, PC boards, and communication wiring. A failure in one area can cause performance issues throughout the entire zone network. That’s why Pack-Timco’s diagnostic process goes deeper than simple troubleshooting.
We diagnose all major mini-split issues, including:
- No heating or cooling output
- Poor temperature control or weak airflow
- Refrigerant leaks or low charge
- Frozen indoor coils
- Outdoor unit icing or water drainage problems
- Communication errors between indoor and outdoor units
- Thermistor, sensor, or control board failures
- Noisy operation or vibration
- Faulty expansion valves or metering devices
- Power issues, electrical faults, or breaker trips
- Wi-Fi control or remote malfunction
Our goal is to find the exact source of the problem — not just treat symptoms.
Expert Repairs for Single-Zone and Multi-Zone Systems
Mini-split systems require precise repairs due to their sensitive electronics and advanced inverter compressors. Pack-Timco technicians are trained in the specific requirements of ductless systems from the industry's leading manufacturers.
Our repair services include:
- Refrigerant leak detection and full recharge
- Compressor, fan motor, and reversing valve replacement
- Control board, sensor, and communication cable repair
- Line-set cleaning, insulation, and correction
- Coil cleaning and airflow restoration
- Drainage and condensate pump repairs
- Electrical and wiring corrections
- Calibration of inverter components and system testing
- Restoring proper defrost cycle and heating output
Every repair is verified with performance testing to ensure proper operation in both heating and cooling modes, especially during extreme seasonal conditions.
Safety-Focused Approach to Ductless Repairs
Even without combustion, mini-split systems can present safety risks when malfunctioning — including electrical hazards, refrigerant pressure issues, and water leakage that can damage walls or floors. Pack-Timco integrates a full safety review into every diagnostic.
Our engineers inspect:
- Electrical connections and grounding
- Refrigerant pressure stability
- Condensate drainage and pump operation
- Indoor coil condition and freeze risk
- Outdoor unit safety and clearance
- Secure mounting and vibration management
We ensure every repaired system is safe for long-term operation.
Expertise in Modern Variable-Speed Mini-Splits
Mini-split systems today are far more advanced than earlier generations. Pack-Timco provides specialist expertise with:
- Variable-speed inverter heat pumps
- Multi-zone and branch box configurations
- High-efficiency hyper-heat models for cold climates
- Ceiling cassette, wall-mounted, and concealed ducted units
- Smart controls, Wi-Fi modules, and building automation
- Hybrid systems integrating boilers, zoning, or central air
We bring the same engineering discipline to repairs as we do to full system design and installation.
Mini-Split Longevity Through Preventive Care
Mini-splits run nearly year-round — far more than traditional HVAC equipment. Preventive maintenance helps extend lifespan, improve efficiency, and prevent emergency failures.
Pack-Timco’s preventive care includes:
- Indoor and outdoor coil cleaning
- Refrigerant pressure and leak testing
- Electrical inspection and tightening
- Drain line, pump, and pan cleaning
- Defrost cycle verification
- Airflow and filter inspection
- Remote/Wi-Fi control calibration
- Full heating and cooling performance test
A well-maintained mini-split operates quieter, cleaner, and far more efficiently.
Signs Your Mini-Split Needs Immediate Service
Call Pack-Timco for a professional diagnostic if you notice:
- No heating or cooling from one or more zones
- Water dripping from the indoor head
- Ice buildup or frozen coils
- Unusual noises (clicking, buzzing, grinding, whistling)
- Unresponsive remote or irregular temperature swings
- Strong odors or airflow reduction
- Outdoor unit not running or short cycling
- Rising electricity bills
- Error codes on the display or remote
Early diagnostics prevent bigger failures, protect your home, and restore reliable comfort.
