Equipment that is 10 years or older is extremely inefficient and should be replaced, preferably with an energy-efficient model (i.e. Energy Star qualified). When purchasing any type of HVAC equipment, it's smart to go with an energy-efficient model. It will save you a ton of money over the years. You're probably wondering, "So if I choose energy-efficient equipment, why does sizing matter?" It matters! Choosing the proper-sized equipment (i.e. proper heating/cooling output) directly affects your comfort, your HVAC system's efficiency and its maintenance and operating costs. You can see how important and underestimated this topic is. In fact, it has been estimated that over half of the HVAC industry does not size your HVAC systems properly. When you oversize an HVAC system, it can affect a number of areas within the process. For example, the installation will be more expensive. Typically oversized systems tend to cost more to operate, break down often, run inefficiently and require more maintenance.


Oversized air conditioners tend to shut off before they've had a chance to dehumidify the air properly. This results in a clammy environment that may be prone to mold. Oversized furnaces create uncomfortable temperature swings. When your HVAC technician attempts to size your system, they should not be reading a label or simple by-the-book standards. Instead, the calculation should be multi-variable and include factors that are unique to your situation. For example, what is the climate like in your area? How many windows do you have and what size are they? How much insulation is there and what type of insulation is it? How big is the house? Is the house two-story or one-story? How much outside are is sneaking in? How many occupants are there? There are two industry standards that should be used to help determine the proper size for your system. These are "Manual J" and "Manual D", created by the Air Conditioning Contractors of America. Manual J, also called "Residential Load Calculation", is primarily used to determine HVAC size calculations. A reputable HVAC company will tell you that they use Manual J to determine sizing. Manual D, also called "Residential Duct Design", is used to determine duct sizing. When looking for a company to help install your new HVAC system, always be sure to inquire whether or not they use Manual J and D in their sizing and installation process.
