How many BTUs should my furnace be?

A good rule of thumb for unit sizing is you will want a system that will provide you 40 to 45 BTUs of heat per square foot of your home. For example: If your home is 3,000 square feet, you’ll want a furnace that produces between 120,000 BTUs and 135,000 BTUs.

What happens if my furnace is too big?

Oversized Furnace The problem with a furnace that’s too large is that it puts out too much heat for the space, which causes the thermostat to shut the system down early. This places extreme stress on the furnace, which will eventually cause the system to break down.

How many square feet will a 75000 BTU furnace heat?

A 75,000 BTU heater can heat a room of between 1,900 and 3,700 square feet in a cold climate if there is little to no insulation. In more temperate climates the heater fares better, heating an uninsulated room of any size from 2,400 to 4,600 square feet.

How many square feet does a 60000 BTU furnace heat?

A mid-sized home of 2,000 square feet would need approximately 50,000 to 60,000 Btu to heat it properly. With a less efficient furnace operating at 80 percent efficiency this would require a 60,000- to 72,000-Btu furnace.

Is a bigger furnace better?

When units are oversized for the space they’re heating, the furnace ends up working in quick bursts. They’ll turn on when the temperature is low and just end up creating heat pockets. … This makes over-sized furnaces really inefficient. For most homes, bigger units aren’t better.
