It may seem impossible to go overboard with air conditioning at first. The whole point of an AC is to regulate the air temperature in your home, and you can hardly have too much control now, can you? As it turns out, your AC may be oversized for your home if you factor in the cost of installation and operation. In order to answer the question “How much AC do I need?” you need to take into account various factors and understand how your home’s airflow works. BTUs are used to measure the effectiveness of air conditioning. British Thermal Units measure how much heat an AC unit can remove from the airspace in one hour. 20 BTUs per square foot are recommended. Additionally, there are a few other factors to consider. A room’s size and purpose must be considered when cooling it. Multiply the square footage of the room by 20. This is the recommended BTU for your air conditioner. You should usually go a bit above your recommended BTU when choosing a unit. Particularly if your room receives a lot of natural light or if it is a common gathering spot for your family. The appliances in kitchens and laundry rooms will also produce heat on their own, making stronger air conditioning necessary. Climate is another important factor to consider. If you live in a warmer climate, you may need a more powerful air conditioner. To prevent sea air erosion, you might need to consider the unit’s specific protective coating if you live in a cooler coastal climate. The answer to the question, “How much AC do I need?” depends on a couple of factors. Decide whether you want a single-zone mini split AC system or an entire house AC system. In addition, you should consider the size of the space you wish to cool. By doing so, you can calculate the required number of BTUs and the right AC size.
