Question about Heating & Cooling
I am being sold a Hitachi Madris ac console of 18,000 btus for a 24x12 toom
Is this brand a good buy?
Do I need 1`8,00 btu for a 24x12 room?
Hitachi is a good brand, I wouldn't be afraid of it.
As to the size, it seems a little 'oversized' for the room you're talking about.
24x12 = 288 sq ft. As a general rule you need 12000 btu for every 600 sq ft.
I'm thinking between 6000 -10000 btu ought to be big enough.
Lots of things go into sizing, and the size of the room is important - but the 'heat load,' needs to be considered too. For example - will there be a lot of people in this room, or is there a lot of windows, is there electrical equipment in this room that will be putting off heat, and how well is it insulated? So you need to consider all of these things when deciding what size unit to buy.
For example - if this room is a bedroom and used primarily for sleeping - I wouldn't be afraid to put a 6000 btu unit in it - but if it was going to be used as a place with tv's, computers and other electrical equipment I might want to put a 10000 btu (or larger) in it.
Generally speaking, it sounds like 18000 btu is too much AC here, and there's no reason to spend more money than you need to and you can 'oversize' just as easy as you can 'undersize' when it comes to Air Condtioning.
