There is nothing quite so uncomfortable as sitting in a building, no matter what it might be, for any length of time in the heat of the summer with no form of interior cooling available. While most church buildings are so designed as to remain relatively cool in the hot summer months, ante-rooms and offices attached to the church are not generally so well designed.
In order to keep people cool, there needs to be some kind of air cooling system in place. Unfortunately, the installation of large HVAC systems can be prohibitively expensive, especially for churches in localities with small congregations and similarly small budgets.
Portable Air Cooling
Luckily, there is a simple and often relatively inexpensive solution to the problem and one that has been adopted in a number of southwestern churches for their smaller rooms. That is buying in those small, portable air conditioning units that are powerful enough to keep a small to medium sized office cool without cutting into the budget both for purchase and day to day running.
We put our first one in nearly eight years ago and immediately benefitted from its rather incredible air cooling ability that was a most welcome addition for our secretary's office where we had four people working at any given time. The unit was placed near to a small window and the exhaust vent simply connected to an old window fan apperture that hadn't been used in years. The cooler working atmosphere was a welcome respite to a particularly hot summer!
