When it comes to heating and cooling your home, it’s very important you get the correct size. The size of your equipment actually plays a huge role; if you buy an HVAC system that’s too big, you’ll end up wasting money and energy, and if it’s too small, you won’t get enough cool or warm air flowing through your home.
When we refer to size, we’re not talking physical size of your unit, we’re talking number of BTU’s. BTU is a unit of measurement for energy; one BTU is equal to the amount of energy used to raise the temperature of one pound of water one degree Fahrenheit. You can usually get a rough estimate of BTU’s needed by looking at the square footage of your home. Check out the chart above.
GEN3 Electric & HVACcan help you determine exactly which make, model and size unit is best for you and your needs. Sometimes, having a little extra power isn’t bad, as it will ensure your system can handle the load on days with extremely high or low temperatures. If you end up with a unit that’s too small, you may regret it on the hottest or coldest days of the year.
Just beware of getting too big of a unit, because it will heat or cool your home too quickly and then shut off. This frequent on and off cycle will cause uneven temperatures and higher energy bills. A good rule of thumb is the maximum size unit you should buy would be 15% over the BTU’s you need for cooling and 40% of the BTU’s for heating. The max for heat pumps is 25%, since it handles both heating and cooling.
