What is better – central air conditioning, highwall or window units?
This depends largely on individual circumstances for example, how large is the area to be air conditioned, how large is the family, what temperatures are required, how well the house is insulated, where the house is located, etc. Central systems require internal ducting; window units take up valuable window space. In many cases, high-wall air conditioner is an optimal choice. Your contractor can advise you.
