Our church’s main building is really an old, converted manufacturing building with a flat roof.
And originally, only the manufacturing company’s offices were air conditioned.
So when the group of us bought the building, a necessary thing that needed to be done was install central a/c. A committee looked into the opportunities by calling local Heating plus A/C businesss. There was the traditional type of central a/c, in which an exterior part is connected to a forced air furnace. The furnace would hold an evaporative heat exchanger plus fan, while the the exterior part would carry the compressor, compressor fan plus a third heat exchanger; Comparatively, rooftop cooling systems house the entire method on the roof. Aside from bypassing the furnace, rooftop cooling systems limit how much work that the component is required to do, therefore lowering energy cost. Additionally, since a rooftop cooling system is contained in a solo unit, any future issues would be simple to address by an Heating plus A/C business. Rooftop cooling systems are most popular with commercial buildings, as they are more efficient in cooling vast, open spaces. Our sanctuary holds almost four hundred people, so this factor is important to us. Once the information had been collected, every one of us looked at the total cost of installing either of the two systems. The conventional a/c option wasn’t as expensive to put in; however, the long-term costs would end up to be more than the rooftop cooling system. The primary reason that rooftop units are more expensive to put in is that they have to be carried up to the roof, requiring several certified Heating plus A/C techs. The additional techs would be needed for an entire day in order to fully complete the initial set-up. Every one of us did end up going with option two, plus over the years every one of us have loved having reliable, cooled air during our church services.
