Split air conditioner ON or OFF during ventilation

Hello everyone,

this year we are heating our house completely for the first time with split air conditioning units. So far, it is working very well. Now I am wondering whether I should turn off the units for ventilation or let them run continuously. We do shock ventilation 3-4 times a day for about 5 minutes each time. Since the room air temperature naturally drops sharply during this time, the air conditioning units immediately start blowing warm air strongly. Within 10 minutes, the rooms return to the set temperature.

From the perspective of energy consumption, it obviously makes sense to turn off the units during each 5-minute ventilation. This is what you do with normal radiator thermostats as well. But what does this mean for the air conditioning units? Is it somehow problematic to turn them off briefly and then turn them back on?

How do others who heat with air conditioning handle this?

Regards Simon

Every compressor start causes wear, so this aspect should argue in favor of running continuously. The energy costs, on the other hand, are probably not significant. Turning off radiators is, in my opinion, nonsense and due to technical misunderstanding. When you turn off the valve, there is still hot water in the radiator and energy is lost. This energy loss is likely only slightly less during the 5 minutes of airing compared to when the valve is open and fresh water continuously flows in during these 5 minutes. Airing itself is already annoying enough, but turning off and on a dozen radiators every time to save 2°C...
