What Size Should My Replacement Air Conditioner Be?
You’ve reached the point where it’s time for an air conditioner replacement or perhaps you see this point approaching quickly, but how do you figure out 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 production will not require it to operateas long. This is known as “short cycling” and it increases the wear on your system and in turn reduces the lifespan of your system. An oversized air conditioner will cost you more money up front and down the road.
 
On the other hand, a system that is too little will run 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 costs will be higher and your comfort will be impacted because of that. It’s very important to talk to a pro that will do a load calculation and advise you on the right system for your needs.
 
How is Load Calculation Determined?
A home’s load calculation used to be calculated based only on square footage and was often erroneous. Technology and knowledge have made a lot of advances since then. When you’re ready for a replacement air conditioner, one of the pros from Precision Mechanical will study your home as a whole and then be able to provide 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 all-encompassing assessment of your needs.
 
An accurately sized and functioning HVAC system will not only keep you more comfortable, it could also save you money.
