Central air conditioners frequently use just one thermostat to manage their cooling ability and fan velocity. When the thermostat is found in the lounge wherever the airflow is large, the central air conditioner will not likely ramp up its cooling power for the bedroom that is certainly struggling from minimal airflow since it detects sufficient cooling in the lounge.
However, the above duct work for hvac mentioned won't promise you a a single-time good results because you will discover other factors such as duct length, inner cleanliness of the duct and etceteras that will impact the conduct in the airflow.
