There are so many things you don’t realize about buying and installing an air conditioning unit until you do it for the first time. As an example, most people assume that AC units come in one size – but that’s not the case at all. They vary in size depending on what you need for your home, and you must make the right choice to avoid wasting money and ending up with an ineffective air conditioning system.
How do you pick the right size AC for your home? It usually depends on these factors:
How Many Rooms Will It Cool?
Start off with an obvious question: what’s the purpose of your AC unit? If you want something that offers practical cooling solutions for your entire home, then you’ll need a much bigger unit than someone who’s just looking to cool one specific room.
For the former, you’re looking at a whole-home AC system that uses vents and units in different rooms to make sure everywhere stays cool. For the latter, you could probably get away with a portable AC unit from Amazon or Home Depot – especially if the room you need to cool is small.
The best thing to do is to find the square footage of your rooms and then search for AC units that cover this area. Most shops will have options to let you shop by room size, so you never end up buying something too small – or something that’s too big and wastes money/electricity.
The Heat Gain Calculation
If you stop after reading the above point, you still may end up with an inefficient AC unit for your home. As explained by SameDay Heating & Air, all homes need to undergo a heat gain calculation that works out one key thing:
- The amount of heat that enters your home during the summer
This calculation basically tells them how hot your home is likely to get, and it factors in things like insulation, room dimensions, ceiling heights, etc. It goes deeper than just looking at the square footage and deciding that a specific AC size is ideal for you. When you get this calculation done by professional HVAC experts, they’ll be able to pinpoint the exact size that makes sense based on how much heat your home retains.
It’s really useful for preventing you from spending a lot of money on a high-powered unit that simply isn’t necessary for your home. Too many people do this, and it results in them wasting electricity and money because their home is already decent at reflecting heat. Sometimes bigger homes have smaller units than small homes, and it’s all to do with heat gain.
Ultimately, these are the two main factors to think about when choosing the right size AC unit for your home. If you’re only cooling one room, you don’t always need to worry about the heat gain calculation, as any single-room AC unit will do the job. It gets more complicated when you seek whole-home solutions, in which case the calculation is essential for filtering out which AC units are more appropriate than others.
