45 000 12 000 3 75.
3 ton furnace square footage.
3 75 1 0 2 75 so you d need a 2 5 or a 3 ton sized central air conditioning unit.
You can also get a rough estimate by looking at the square footage of your house.
Using your formula i figured a total square footage in my home at 1595 25 sq ft.
Acs are sized in tonnage which measures the amount of cooling the unit can provide in an hour.
If you are looking to save on energy costs you can consider buying a 3 ton heat pump split system.
This home would require a furnace that has a tonnage of approximately 3.
House square footage times 30 divided by 12 000 1 0 required tonnage.
But it s vital to understand that there are.
High efficiency furnaces can help you save during the colder months of the year by using less natural gas to heat your home.
This chart is a general guideline that covers tiny houses to average size homes.
Some of the most efficient units today can get up to 97 3 annual fuel utilization efficiency afue ratings.
For example a 95 rated efficiency furnace with a power rating of 80 000 btu hr has a power output of 0 95 x 80 000 btu hr 76 000 btu hr.
I felt a 3 ton unit would be enough but in the square footage i measured itt includes a den with a high open beam celling.
In general purchase according to 1 000 square feet per ton.
A gas furnace does require that your home is.
A quality three ton heat pump can effectively heat or cool an average area of 1 500 square feet but will be too large for smaller spaces.
Its like a rectangle measuring 17 5 x 19 5.
1 500 x 30 45 000.
Divide the result from step 4 by 12 000 to determine the tonnage requirement of the furnace.
Many different factors other than square footage that determine how effective the any heat pump will be.
So while 3 ton heat pump may be labeled and sold as three ton unit it may not produce anything close to its rated 36 000 btu h in cooling.
Furnace output and air conditioner size for a bungalow.
So for instance a 1 500 square foot home would look something like this.
The outside edge is 10 ft high then it goes up a little over 12 ft.
The celling is on the longer side of the four walls.
Keep in mind that the following furnace output power estimates are aside from the furnace s nominal power ratings.
In the example you would divide 35 000 by 12 000 and get 2 92.
Typically residential acs range from 1 ton units to 5 ton units half sizes included i e 2 5 tons.
