\"AC-units-on-roof\"We offer service for light <\/span>commercial HVAC in High Springs, FL<\/span><\/a>. \u201cLight\u201d commercial means we work with AC and heating units that are 25 tons and under. No, that doesn\u2019t have anything to do with how much the equipment weighs. The \u201ctonnage\u201d of a system is a bit more complex, and it has to do with the amount of heating and cooling an HVAC unit can provide.\u00a0<\/span><\/p>\n

This applies to residential ACs and heaters as well, so even if you don\u2019t own or operate a commercial facility, you may wish to stick around and learn about how professionals determine the amount of power necessary to provide climate control for a building.<\/span><\/p>\n

Tons of Cooling, Tons of Heating!<\/b><\/h2>\n

The tonnage of a system is a handy description for HVAC professionals to express the capacity of an HVAC unit to either remove heat from a building (cooling) or add heat to it (heating). The standard measurement of heat (either added or subtracted) is the British Thermal Unit or BTU. A BTU is the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit.\u00a0<\/span><\/p>\n

If you look at a small window air conditioning unit, you\u2019ll see BTUs listed on it: that\u2019s the amount of BTUs of heat the AC can remove from a space over an hour. Most window ACs can remove about 5,000\u20136,000 BTUs per hour. But when you start moving to any system larger than window air conditioners, you\u2019ll be dealing with extremely large numbers. For example, a standard light commercial air conditioning system may remove 240,000 BTUs an hour.\u00a0<\/span><\/p>\n

Here is where the <\/span>ton<\/span><\/i> comes along: it\u2019s an easier measurement than using the smaller BTU. One ton is equal to 12,000 BTUs removed per hour. Residential air conditioners are between 1 to 5 tons. Up to 25 tons is light commercial, and anything above that is considered a heavy commercial or industrial system.<\/span><\/p>\n

But Why Is It Called \u201cTons\u201d?<\/b><\/h2>\n

Yeah, it does sound strange. But there\u2019s a reason for it, and the reason 12,000 BTUs was selected as the base unit for heat measurement: 12,000 BTUs is the amount of heat necessary to melt one ton<\/strong> of ice at 32\u00b0F in 24 hours. This measure was set by the American Society of Refrigerating Engineers way back at the beginning of the century, and we\u2019re still using it. (Except for small equipment like window ACs, which are only fractions of a ton.)<\/span><\/p>\n

Professionals and Proper Sizing<\/b><\/h2>\n

If you\u2019re wondering how many tons of heating or cooling your commercial business requires, we have good news: you don\u2019t have to worry about that when it comes to installing or replacing equipment.
