The episode features an interview with Marek Mozga, a mechanic and motorization enthusiast, on Radio Plus Szczecin. The host introduces air conditioning as a standard but often overlooked car feature. Marek begins by explaining that air conditioning systems naturally lose small amounts of refrigerant over time, debunking the myth of perfect tightness. He recommends servicing every 2-3 years to check for leaks and replenish oil. The conversation covers the cabin filter, which should be replaced yearly or every 10,000-15,000 km to prevent health issues from accumulated dirt. Marek addresses common problems like bad smells from vents, often due to a dirty filter or evaporator needing cleaning. He discusses why air conditioning might stop cooling, typically from refrigerant loss or compressor failure. Marek notes that air conditioning technology has changed little over 25 years, with automatic controls being the main update. He advises using air conditioning year-round to dry air and prevent fogging, which reduces system issues. The episode touches on zoning for disinfection, a concept from the COVID period. Marek strongly warns against using old refrigerant in new systems, as it can damage compressors and require expensive repairs. He mentions that professional workshops now check refrigerant quality before servicing. For used car buyers, Marek suggests checking cooling function and the condenser's condition, but emphasizes professional inspection. Repair costs vary: a condenser replacement might cost 400-600 zlotys, while compressor issues can run into thousands. The episode concludes with Marek stressing that proper maintenance saves money.
