Home A/C?

[Geoff87]

What's the rule of thumb as far as BTU's/Size of room in sq. ft.?

Different for a split system vs window mount?

I just know that you need 4000 BTU's per/1000 cubic feet. Also you got to factor in the windows, doors and furniture. But normally a standard bedroom is about 1000 sq. ft but there are no 4000 BTU's for an airconditioner so you will have to purchase a 5000 BTU A/C.

 

[Geoff87]

Thanks!

So, the general rule of thumb would be 4000/100 sq ft. Give or take? (Hot side of home), etc...

(Can't be per 1000 sq ft.....!! )

If you interested in a split system let me know. I have a good friend that installs and sell split units for home a commercial.

Screw the BTU Limits...the bigger the better..comes with a bigger elec bill though I should know...our house has central a/c. our elec bill sees mid $400/mo. sometimes lower in the high $300 range. once it was over $600 cause it was one all day...all night, when we 1st got the house.

oh boy

Geoff,

usually for residential construction, we use 350-400 sq ft per 12,000 btu (35-30 btu/sq ft). west facing rooms getting the higher loads. if your rooms have a lot of windows, you may want to add a few 1,000 btu's.

window a/c:
cheapest first cost
not as energy efficient as a split system.
louder.
need electrical outlet nearby.

if you use the window unit, get one that has a "slinger". this will almost eliminate any condensate dripping from the unit.

ductless split

higher cost (~$2500 for a 12,000 btu system)
indoor unit should be mounted on the exterior wall.
be careful of where the condensate drain is routed, especially if you have ground termite treatment. the condensate can wash away the chemicals.

if you want to a/c multiple rooms, the split has a 3 in 1 package where 3 indoor units are connected to one outdoor unit. the hard part routing the pipes from each indoor unit to the outdoor unit.


bigger is not necessarily better. a little bigger is fine, but grossly oversized systems will make the compressor cycle on-off too quickly reducing the useful life of the equipment.

Thanks for the info Carey! Now when are you going to race that car?

with AC....bigger is not always better

When I had my central air installed and they showed me the outside unit I thought it was kind of small. I asked if I could have a larger system and here is what I was told.....

"Too many people buy a larger system than they need. You do not want a system that is too large for your house becuase it will cool the house down before it removes the humidity. That leaves you with a cold wet house. A smaller unit will get the house just as cool but will take longer to do so, thus removing more humidity from the air."

I remember someone telling me the same thing a while back. Thanks for reconfirming that.
