So, I'm in the process of re-thinking my A/C. I may simply be replacing a unit (one of three), or just re-designing the whole darn thing.
Hence, I'm asking all sorts of questions.
I'm a slightly strange homeowner -- HVAC problems actually keep me awake at night!
In any case, and this is a question I've pondered over the years, here goes...
How does one best deal with an area in a house that gets a lot of exposure to the outside?
In my own house I have three such areas. This is South West Fla.
1) A laundry room, right off the kitchen, that leads to the garage. We are going in and out constantly. At times, we go in and out so often, that the door might as well be open full time.
2) A living room. Very large, 20' X 20', but communicates with the pool area. So, when the pool is in use, the kids are in and out non-stop.
3) A bedroom. Right by the pool. Less use but still, the door is letting in a lot of outside air.
In short, we live a very indoor/outdoor lifestyle.
I've thought of two solutions:
1) Just install an additional, large, regular A/C return over each entrance.
2) Over each often-used entrance (inside the house, I mean), for example in the laundry room foyer, I could install an in-line fan. It would be exhausted to the outside. I would run it at low CFMs, say 20-40CFM -- but constantly.
Negative pressure is not a problem, because we're coming and going so often. But, if each area that get open to the outside all the time, has an exhaust fan, less of the hot, not-conditioned air gets into the house. Or so I'm thinking??
And all input is always very carefully considered, and much appreciated!! (And will keep me awake...considering...things...)
