I work as a cleaning guy part time for a church here in my local area. The time of year that the church has to be cleaned the most is during the Summer months when it is very hot and humid outside. At this time of year, a ton of dust and dander gets all over the place from the doors being closed up and people coming in and out. This is why the church has recently invested in a brand new, top quality heating and cooling system with an air purifier system as well. This has made my job a lot easier this year with the wonderful air conditioning system and air purifier. I have a lot less to clean and not to mention it is very nice and cool in there. This is the latest in HVAC technology and it has helped not only me, but those who come to the church weekly for service. They feel a lot more relaxed in here and they breath better. Even the weddings they have had been a lot more relaxed since they put in this brand new, up to date and very top of the line heating and cooling system with the air purifier in it. It makes the whole experience a lot better, not to mention, the HVAC system works really great! I think I may actually look into a top quality brand new top of the line heating and cooling system for my home as well. After experiencing this here, it has become a major must for me this year as well. Onward and upward as they say! And I will be getting one real soon!
