Whether you’re building a new home or simply getting ready to replace the aging HVAC system in your existing property, the right air conditioning system will provide efficient and effective cooling and humidity removal to create the indoor environment you want. However, finding the right air conditioner means not only choosing the type of cooling system you prefer for your home, but also determining the size and capacity of the appliance you need to install as well. Installing an air conditioning system that is too big or too small for your home will result in poor temperature and humidity control that affects daily comfort, as well as greater system strain that will raise your cooling costs and shorten the expected lifetime of the unit. Before you schedule the installation date for your new air conditioner, it’s first important to work with your Miami HVAC service to calculate the capacity your AC until will need to ensure you make the most economical and appropriate choice.

The Size of Your Home

One of the most significant factors that affect the size of the AC unit that’s right for your needs is the size of your home. Air conditioners are rated with varying capacities, which are measured in tons of cooling. This measurement actually indicates the amount of heat an air conditioner can remove from a home in an hour. The amount of heat you’ll need to remove from your home each hour is directly affected by the amount of air in your home, which is related to its square footage and its volume. Most residential air conditioning systems range from one- to five-ton systems, and several smaller systems can be installed to achieve a cooling capacity higher than five tons if necessary. It’s also important to note that installing a larger AC unit than you need won’t provide more cooling—an air conditioner that is too large will cool just as inefficiently as an air conditioner that is too small.

Your Home’s Ability to Resist Heating

The ability of your home to naturally resist heating also plays a part in the capacity of the AC unit you’ll need. During the summer, both the sun’s energy and the ambient temperature outdoors will try to make the air inside your home warmer, while your air conditioner will work to counteract any heating that does occur. Thus, a home that is better able to resist heating will require a smaller air conditioner than a home that isn’t able to prevent heating as well. The amount and type of insulation in your home affects its resistance to heat, as well as the quality, amount, and condition of weatherstripping and other weather-resistant material around doors, windows, vents, and other access points. Additionally, the number of windows, doors, and other access points in your home will affect the amount of air transfer that can potentially occur throughout the day, causing cold air loss and hot air gain that must be offset by your AC.
