How to Know if Your Heater is Powerful Enough for Your Space

As the temperatures drop even more, your heater’s job becomes increasingly important. You want to stay warm without any doubts about your system’s power. But what if your furnace is too big or too small for your house? That can have a huge impact on keeping your home warm and your family comfortable.

A furnace that is too small can cost you more on energy bills and add wear and tear to the system. A furnace that is too large can overheat and short cycle, leading to a shorter lifespan. If you’re not sure whether or not your heater is big enough, you may need heating services in Glendale, CA. Keep reading to learn more about how you know if your heater is powerful enough for your space.

Choosing a “Just Right” Furnace 

When you’re choosing a furnace size, you start by measuring the square footage of your home. If it’s not on the paperwork from your original home purchase, you can measure the individual rooms and add them all together. Keep in mind that you don’t have to measure garages or sunrooms that will not have air vents for heating and cooling. 

After that, you want to consider which of the US climate zones you live in. Glendale is in climate zone three. Because it doesn’t get quite as cold here, you don’t need a heavy-duty furnace. However, you may want more power for your air conditioning system in the summer when it’s warm. Talk to a member of our team to learn more about how climate zones impact your choice of a furnace.

In zone three you want to have between 40 and 45 BTUs per square foot of your home. BTU is an acronym for British thermal units, which is how experts measure the power of an HVAC system. Put simply, a BTU is the amount of energy that is necessary to heat a pound of water by 1°F. 

There’s more that goes into the calculation than just square footage and your climate zone, though. Furnace sizes can overlap a lot when it comes to the square footage of your home, so choosing the right unit requires the help of an HVAC expert. If trying to calculate, the furnace size is too much for you, we can help.
