What Size Should My Replacement Air Conditioner Be?
You’ve found yourself the point where it’s time for an air conditioner replacement or perhaps you see this point approaching quickly, but how do you determine the size of system you’ll need? Choosing the best size is critical 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 production will not require it to workas long. This is known as “short cycling” and it increases the wear on your system and in turn reduces the lifecycle of your system. An oversized air conditioner will cost you more money up front and in the long run.
 
On the other hand, a system that is too little will operate too long and won’t be able to fully cool your home when the weather gets hot. An incorrectly sized system will have to work harder, your energy expenses will be higher and your comfort will be affected because of that. It’s very important to talk to an expert that will do 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 decided based only 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 professionals from Contra Costa Heating & AC will study your home as a whole and then be able to offer an accurate load calculation. Load calculations are made of everything from the construction of your home, amount of insulation, the local climate and type and color of your roof, to the number of home occupants – a truly complete assessment of your needs.
