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 rapidly approaching, but how do you determine the size of system you’ll need? Picking 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.
Installing a system that is too large wastes energy and money. A larger system will constantly be warming up and cooling down because it’s productivity will not require it to runas long. This is known as “short cycling” and it increases the wear on your system and in turn decreases the lifecycle of your system. An oversized unit will cost you more money up front and in the long run.
 
On the other hand, a system that is too little will run too long and can’t fully cool your home when the weather gets hot. An inadequately sized system will have to work harder, your bills could be higher and your comfort will be affected because of that. It’s very important to work with a pro that will perform a load calculation and advise you on the correct system for your needs.
 
How is Load Calculation Determined?
A home’s load calculation used to be determined based solely on square footage and was often wrong. Technology and knowledge have evolved a lot since then. When you’re ready for a replacement air conditioner, one of the experts from Three Rivers Heating & Cooling will study your home as a whole and then be able to provide an accurate load calculation. Load calculations include 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.
 
A correctly sized and functioning HVAC system will not only keep you more comfortable, it could also save you money.
