About the service
I specialize in installing ductless mini-split systems for owners of private homes and apartments without central ventilation, where running ductwork is impractical or too expensive. Most often I work with owners of old homes, converted attics, extensions, and garage conversions — for such spaces a mini-split system solves cooling and heating without cutting wall channels for ducts: one outdoor compressor-condenser unit, one or several indoor wall-mounted, cassette, or floor panels, and a thin refrigerant line through a hole about 7-8 cm in diameter.
The work starts with a site visit and thermal load calculation. I don't estimate power by eye based on room area, but calculate required BTU accounting for wall insulation, window orientation, ceiling height, and regional climate data — oversized capacity leads to frequent on-off cycles and energy waste, undersized capacity can't handle peak heat. After agreeing on the model — I regularly work with Mitsubishi, Daikin, Fujitsu, Gree, and Midea equipment, both single-circuit and multi-split lines — I handle the full scope: mounting the indoor unit level on a solid base, laying and insulating the line, drilling and sealing the wall opening, installing the outdoor unit on a vibration-dampening pad with proper clearances, and if needed, running a separate electrical line.
Vacuuming and pressure testing is a stage where dishonest installers often cut corners, so I always vacuum the line to 500 microns with a hold before releasing factory refrigerant, and additionally check superheat and subcooling with gauges rather than relying only on the sight glass. Every installation ends with full commissioning: I check condensate drainage and drain pump operation if present, test cooling and heating modes, remote control or smart module binding, and explain maintenance and filter cleaning procedures to the customer.
A single-unit system typically installs in one work day, a multi-split with two to four indoor units in two to three days depending on line length and finishing work after installation. I provide a photo report of the hidden line, electrical connections, and startup parameters for warranty service. I also handle repair and replacement of compressors and lines on already-installed systems if the previous installer left a leak or undercharge of refrigerant.
