If you are new to the world of indoor cooling, you may want to learn what size central air conditioner to purchase for your home to take care of excess heat in the space. Some of the best air conditioners, after all, are central units, and these appliances ship in a wide array of tonnage sizes to suit different home layouts, from how many rooms you have, the insulation, how many windows there are, how many housemates you live with, etc. If you live in a very hot climate year-round, a central AC can be a great investment, but it’s important to get the sizing right since the wrong size can be ineffective and a waste of money and increase your energy bills. So if you’re wondering, “What size central air conditioner should I get?” keep reading to find out.
The size of an air conditioner depends largely on its cooling power and the overall dimensions of your home, which is why many people wonder what size air conditioner is perfect for 14×70 mobile homes. If you already have an air conditioner, just look at the BTU rating and replace it accordingly. You might want to look into energy-efficient models if you’re looking to save on your energy bills more. However, if you don’t have a central system in place, you need to figure out your home’s size and answer some other questions, such as how big of a generator you need to run a 5000 BTU AC Unit.
No matter what size you choose, remember to change out the air filters every two months or so, depending on usage.
Luckily, there are some fairly standard ways to pick a correctly sized AC unit for your home, so you can move on to learning where the contactor is located within your air conditioner.
There are plenty of calculators available online for just this purpose. These apps ask for some simple information, such as your home’s size in square footage, and come back with the perfect BTU rating for you. Once you have this information in hand, start shopping for a central air conditioner or full HVAC system. Many of the major AC manufacturers operate these calculation systems.
Generally speaking, you’ll add 1,000 British Thermal Units (BTUs) for every 100 square feet included in your home. An extremely small home of 150 square feet requires 1,000 BTUs, for instance, while a larger home of 1,000 square feet requires 20,000 BTUs. When shopping for a central AC system, check out the specs. These specifications typically include the cooling power in BTUs, and some even include the maximum amount of physical space the AC can handle.
As a last resort, simply call and talk to a professional AC installer. These pros will be more than happy to answer your questions about air conditioner sizes relating to home size. Have your home’s square footage available before making the call to find out the properly sized units faster on the call.
STAT: Having a little extra power from a slightly bigger size unit than you need isn’t bad. This will make sure your system can handle the load on days with extremely high or low temperatures. If you get a unit that’s too small, you may regret it on the hottest and coldest days of the year. (source)
