How much btu for A/C?

8 years ago

So we want to install an air conditioning unit in our townhouse (Quebec, Canada). There are 2 floors and each floor is about 625 sq.ft. We asked around for quotations and most companies recommended 12000 btu. I've googled online and it seems low. The other alternative that's 1000$ more expensive is 18000 btu. So I would like to ask advice, how much btu do you have at your property? Thanks!

Location, size, and climate are important...It would be helpful to know the usual summertime average temps your climate has...average not max!

you should know 2 small zones one system like you have can be problematic as far as comfort.

Your cooling load in Quebec is likely to be low, so a 1 ton (12,000 BTU) AC may be sufficient. Have this discussion with your dealer and ask to see the cooling load calculation. If it doesn't cool adequately, let them know that you'll be coming after them!

"a 1 ton system may be difficult to purchase..."

Yes, you're right. For some reason, I was thinking minisplit, but the smallest size a regular split system comes in is 1.5 tons.
