What Size Should My Replacement Air Conditioner Be?
You’ve come to the point where it’s time for an air conditioner replacement or perhaps you see this point on the horizon, but how do you determine the size of system you’ll need? Choosing the correct size is very important for your system’s efficiency and your home’s comfort. There’s a perfect air conditioner out there for you and your home’s needs.
 
When replacing your system, bigger isn’t always better.
Buying a system that is too large wastes energy and money. A larger system will constantly be warming up and cooling down because it’s output will not require it to runas long. This is known as “short cycling” and it increases the wear on your system and in turn hurts the life of your system. An oversized unit will cost you more money up front and over time.
 
On the other hand, a system that is too small will operate too long and will not be able to fully cool your home when the weather gets warm. An incorrectly sized system will have to work harder, your energy expenses may be higher and your comfort will suffer because of that. It’s very important to talk to a pro that will complete a load calculation and advise you on the best system for your needs.
 
How is Load Calculation Determined?
A home’s load calculation used to be calculated based exclusively on square footage and was often incorrect. Technology and knowledge have evolved a lot since then. When you’re ready for a replacement air conditioner, one of the experts from Connolly Electric & Mechanical will study your home as a whole and then be able to provide an accurate load calculation. Load calculations are composed of everything from the construction of your home, amount of insulation, the local climate as well as type and color of your roof, to the number of home occupants – a truly comprehensive assessment of your needs.
