Ductless Mini Split Repair in Manchester, NH
All Brands
Our technicians service all brands, including Mitsubishi, Fujitsu, Daikin, LG, Samsung, and Gree. We read the fault codes, test the system, and explain the repair before work begins.
Leak Detection & Repair
Water at an indoor unit often points to a clogged or disconnected condensate drain. Refrigerant leaks require proper leak detection, repair, and system charging according to the manufacturer's specifications.
Electrical Diagnostics
Communication errors between indoor and outdoor units, board failures, and sensor faults. We diagnose and repair the whole control system.
Deep Cleaning
Dust and biological buildup can collect on the blower wheel and coil. A proper cleaning can restore airflow, reduce odors, and help the system operate more effectively.

Thorough Mini Split Diagnosis in Manchester
Ductless problems are not always caused by the first symptom you notice. Water near an indoor unit may come from a blocked drain, drain-pan problem, or failed condensate pump. Weak airflow may point to dirty filters, buildup on the blower wheel, or a coil problem. Loss of heating or cooling can involve controls, sensors, wiring, or the refrigerant circuit. Our technicians work through the system in order, identify the cause, and explain the repair before replacing parts.

Ductless Mini Split Repair FAQ
My mini split is leaking water inside. Is this serious?
A clogged condensate drain is a common cause, but the unit should still be checked before water damages the wall or floor. We clear the drain, inspect the pan and pump when present, and confirm that the unit is draining correctly.
The unit is running but not cooling. What's wrong?
Most common causes: low refrigerant (leak), dirty indoor filter, frozen evaporator coil, or a failing outdoor compressor. We diagnose to find the specific cause and give you an upfront quote.
Is it worth repairing an old mini split?
We look at the system's age, brand, parts availability, repair cost, and overall condition. A sound system with one failed component may be worth repairing. An older system with a major refrigerant or compressor problem may be a better candidate for replacement. We explain both options when they are reasonable.
Can I clean my mini split myself?
Homeowners can wash or vacuum the reusable filters according to the manufacturer's instructions. Cleaning the blower wheel, drain pan, and indoor coil requires partial disassembly and is better handled by a technician. Check the filters regularly during heavy heating or cooling use.
