Proper System Sizing

A lot of real science is included in the methods of calculation when selecting the correct size key air conditioner for your domicile. For case, i of these methods is a Residential Load Calculation.

Another method for sizing air conditioners is determining the size of the air conditioner organisation that's currently in place. Manufacturers normally don't listing the size of the air conditioner unit but don't worry! The system capacity is almost e'er coded into the model number of the outdoor unit.

In about cases you tin use the conversion information below to help in determining the size of your existing air conditioner organisation (use the system model number Non the series number)

18 = 1.5 tons
24 = 2 tons
30 = 2.5 tons
36 = three tons
42 = iii.5 tons
48 = 4 tons
60 = 5 tons

A Warning Before Y'all First Sizing Your Air Conditioner: Practise non to make the error of buying an A/C that's also large! When yous install an air conditioner that'south besides large for the infinite, it does what is called a 'short cycle'. A short wheel is when the compressor doesn't run for enough time to dehumidify the surface area you're trying to climate control. A short cycling A/C system isn't the only concern; in most cases the system volition cycle on and off more often, this translates to an increase in operating costs and an overall reduction in the system'south life. Proper air conditioner sizing is critical to optimize performance.

Heating Guide

Hither nosotros will cover how to apply the heating guide portion of this selection guide. You will need to utilise the lower of the two numbers if you know your home to be well insulated; apply the higher number if your home is older and poorly insulated – be honest! It volition pay off in the stop. (Hither'southward another Hint: You should select the larger of the two numbers if you're completely unsure of your dwelling house's insulation)

If you lot can notice your furnace model number, you can skip the calculation and look up your model number to find exactly what you need. Please refer to this furnace model number decoder to aid determine what you lot currently accept. If you have issues with this, give us a call and nosotros are happy to help.

Yous will then rapidly multiply the correct number higher up past your home's total heated square footage. At this signal you will take arrived at your judge heating capacity requirement.

An example y'all tin reference: If your abode is in the yellow zone, your dwelling house is adequately insulated, and you've got 2000 heated square feet, the equation will look something similar this:

2000 square feet
X 40 heating factor (from the chart above)
80,000 Btu actual output

Adjacent, if yous demand to calculate the output yous need on a gas furnace, just multiply its efficiency by its listed input rating for the BTU output of estrus.

An example you can reference: If a furnace is listed with an input rating of 100,000 BTU's and an efficiency rating of 80%, it would produce:

100,000 Btu input
X .80 efficiency
lxxx,000 Btu actual output

If the aforementioned 100,000 BTU furnace has an efficiency rating of 93% it will produce:

100,000 Btu input
Ten .93 efficiency
93,000 Btu bodily output

Seeing a pattern here? In the example above, using an eighty% efficient furnace, the 2000 square foot habitation above would crave a 100,000 BTU input furnace which will produce the necessary 80,000 BTU's output of heat.

Variables

Let's talk about all of the variables that come into play when selecting a new air conditioner system or furnace. One such Variable is your insulation, some other whole fix of variables being the type and number of windows in the space, number of stories in your home, the construction type, etc. All of these variables will greatly bear on the required BTU's per foursquare for both heating and cooling. A skillful dominion to follow is if your home is well insulated and has newer style windows, y'all can (in most cases) safely choose the smaller size arrangement that conforms to the specs needed for your total square footage.

Is your home 2 story? If the reply to that question is 'yes' it volition place less of a load on the system in the downstairs flooring because the 2d floor acts as boosted insulation. If your home isn't well insulated or if information technology has older manner windows and an obscenely high number of windows, you're going to want to select a larger system that falls inside your specified square footage range. The less insulated and more windows inside the environment, the more than likely you will experience greater air and heat loss.
