In Mykolaiv, officials explained why air conditioners in trolleybuses may not be working

Abnormal heat is creating additional strain on Mykolaiv’s public electric transport. Extremely high temperatures can cause rails, overhead lines, electrical equipment and air-conditioning systems to overheat. This was reported on July 2 , 2026 by the municipal enterprise of the Mykolaiv City Council “Mykolaiv Electrotrans”. The enterprise noted that the period of abnormal heat has covered Ukraine and a large part of Europe. Even in countries with modern transport systems, such weather conditions cause delays and malfunctions of climate-control equipment.

Before departing on routes, trolleybuses and other rolling stock undergo a daily technical inspection. If defects are found, specialists carry out repairs or replace the vehicle with a reserve one. “Mykolaiv Electrotrans” also said they receive passenger reports about non-working air conditioners in some trolleybuses and respond to every message.

At the same time, the enterprise emphasized that at extremely high temperatures even properly functioning climate equipment can operate at the limit of its technical capabilities. For this reason, some malfunctions cannot be fully predicted or prevented. If an air conditioner is running in the cabin, passengers are asked not to open the windows. Open windows reduce the cooling efficiency because cool air quickly leaves the cabin and the system works under increased load.

A malfunctioning air conditioner can be reported to the hotline of the municipal enterprise “Mykolaiv Electrotrans” at: 095 084 38 04.

When reporting, you must indicate the route number, the vehicle’s fleet number and the approximate time of the trip. This will help the enterprise staff locate the vehicle faster and fix the malfunction.
