Requirements for home central air conditioning?

Question

I have a three story home. The top floor has its own a/c system for a living area of about 1,000 square feet with 12 foot ceilings thoughout most of the area and a large surface area for windows. The area is approximately sqaure and by the looks of the attic is not overly well-insulated. My central a/c unit went stopped working (it is 7 years old). What type / brand /size seer rating should I recplace the broken unit with? I was thinking of putting in a whole new unit since it is 7 years old. I currently have a 2.5 ton unit but it can't keep up on hot days, so I was thinking of going with a 3.0 ton unit instead. Any advice?

Answer 1

Have a reputable h.v.a.c company come size the unit properly

the unit is not that old and probly can be repaired.check with the b.b.b in your area and neghbors that have used the company word of mouth is the best

Answer 2

Keep the 2.5 ton on the outside and put a 3 ton on the inside for more latent(moisture)heat removal.You don't want to oversize your tonnage or it will work against you.Like satisfying on temperature before adequate humidity is removed.

I like American Standard.They are top of the line and a little higher in cost.Rheem is a quality unit as well.Goodman is at the other end of the price range but is also a quality unit.

All the makes are comparable to one another in efficiency on 14 SEER or higher and the warranties are also similar.

Answer 3

money is one
