Air Conditioning Sizing Question. First Home Purchase
Well I finally saved enough money for a house even after my stock market losses. This is a new house being built by Ryan homes in North Carolina where it can get up to 95 degrees in the summer and of course 100% humidity. The house will be 2300 sq feet, 2 story with R13 in the walls and I think R30 in the ceilings and such. There is a crawl space. There are no rooms over the garage. 4 bedrooms are upstairs. Windows are double paned. Do not know which way the house faces for sun exposure. 9 foot ceilings down and 8 foot upstairs. There is no basement, all ceilings are flat-no vaulted ceilings. Okay, they wanted to put in a single 3 ton unit outside for this 2300 sq foot house. Now I am used to apt living and like the temp inside to be about 70-72 degrees in the summer. However I live on a bottom floor. The builder does not normally add a second unit unless your house is 2500 square feet or more. However they cut me a deal of $4,000 more with a $2600 credit for a net of $1300 to go to 2 units. Note the house will have gas heat. They recommended and told me this is what theft plan to do: Upstairs: 2 ton unit, 50,000 BTU's, I do not know the tonnage of the blower if that is important. Do not know make or efficiency rating. Not sure if BTU's should match tonnage. Not sure if tonnage is correct.
Answer:
I recall a printing plant back in the 50's that installed air-conditioning. It was not done for the comfort of the employees, but rather the ability to handle paper on the printing presses. Humidity was the prime concern. On cool muggy days they not only ran the AC but the boilers to heat the very cold air. We use the term "air conditioning" in reference to air that is cooled. Truth is, conditioning of air means to filter, adjust the temperature and humidity.
