This large church regularly holds services for up to 2,000 people at one time. The complex also has a number of departments, with many permanent employees. Because it might take up to three hours to cool the main auditorium,

normal air conditioning becomes a very expensive option when the area is normally only used for about two hours at a time.
But JH coolers have an immediate effect, replacing hot air with cool air in just a few minutes, resulting in large cost savings. And JH Coolers never re-circulate the same air, so illnesses such as colds and flu are never transmitted

to other parts of the church complex.
