AC tonnage in the heating and cooling industry refers to an HVAC’s ability to cool a home by removing heat. Tonnage depends on how many BTUs (British Thermal Units) your unit absorbs and removes per hour. The tonnage in average residential HVAC units can range from 1.5 tons, at its smallest, to 5 tons.

In its most basic calculation, tonnage is often determined by the square footage of a home. A general rule of thumb is 600 square feet per ton on an average home. However, square footage may only be one half of the qualifying criteria to determine tonnage. If you go by square footage alone, you may risk installing too much and having your unit frequently short-cycle, sacrificing home comfort.

For the most accurate measurement, you’ll want to have a load calculation performed by a licensed HVAC technician. On top of square footage, load calculations take into consideration the volume of the home, insulation efficiency, roof type, home elevation direction and other determining factors.

A load calculation will say how many BTUs you will lose in the winter versus how many BTUs are you going to gain in the summer. And based off those two numbers, an ideal tonnage size is determined.

Dirt caused the most HVAC issues. We often see dirty outdoor coils, dirty indoor coils, dirty filters and dirty drains. Most HVAC issues can be traced back to dirt that was allowed to get dirtier over time until reaching a critical mass and unit failure.

This is why Parthenon recommends two seasonal tune-ups a year: to keep your unit clean and prevent future issues if left untreated. Parthenon Partners is the best way to receive your tune-ups for a fraction of the cost, as well as receiving top priority and discounts on repairs, installs, and plumbing services!
