Using air conditioning to repel mosquitoes was a stupid way to deal with them, and it was unnecessary to use the AC in early summer or early autumn. Besides, the AC should not always be turned on. People should open windows for ventilation from time to time, or else the indoor air quality would be poor for their health.
In addition, Sphynx cats were rather special because they had no hair to cover their bodies, and unlike bulldogs, they did not have abundant fat to keep them warm during the cold. They were very sensitive to changes in the temperature, and if they were directly exposed to the cold air from the AC, they would catch a cold and get diarrhea easily.
