Our church building is really a converted manufacturing building with a flat roof; Originally, only the business’s offices were air conditioned… So when my associate and I purchased the building, one of the first things that needed to be done was install central air conditioning… A committee researched the possibilities by contacting local HVAC businesss… There was the conventional type of central air conditioning, in which an exterior component is connected to a forced air furnace.
The furnace would hold an evaporative heat exchanger plus fan, while the the outside unit would house the compressor, compressor fan plus a second heat exchanger; Comparatively, rooftop air conditioning units contain the entire system on the roof.
Aside from bypassing the furnace, rooftop air conditioning units limit the amount of work that the unit needs to do, lowering energy cost. Also, since a rooftop air conditioning unit is contained in one unit, any future concerns would be easy to address by an HVAC professional! Rooftop air conditioning units are popular with commercial buildings, as they are more efficient in cooling large spaces. Our sanctuary holds four hundred people, so this factor is pressing. Once the information had been gathered, my associate and I looked at the cost of installing either of the two systems. The traditional air conditioning occasion wasn’t as costly to install, however the long-term costs would add up to be more than the rooftop air conditioning unit. The main reason that rooftop air conditioning units are more expensive to install is that they have to be hauled up to the roof, requiring numerous certified HVAC professionals. The additional professionals would be needed for an entire afternoon in order to complete the initial set-up… My friend and I did end up going with occasion two, plus over the years my associate and I have enjoyed reliable, cooled air during our church services.
