Is ACCA Manual J Calculation Important for My Home?

In very few words, actually just one word, yes. And here is why.

Most of the times, when a contractor doesn’t perform the ACCA Manual J Calculation, he will select an AC that is far too big for the space you live in. 

Will this have negative consequences for you? Absolutely. 

First and foremost, a large AC will definitely show up on your bills. Second of all, being so large, it will cool off your house extremely quickly. You might think that’s great, that’s what I want, but you would be wrong.

Bringing down the temperature too quickly will make the AC turn off many times during the day, essentially going into short cycles. This will shorten its life span and prevent it from eliminating humidity and possible mold spores. 

Moreover, it will use more electricity. Every time it comes back on, the AC causes a spike in your electricity usage. All of these things combined are enough to make you see why it’s crucial to install an AC that is the perfect size for your house.
