However, selecting the perfect AC unit for your home can be tricky– even once you know your brand– especially given the abundance of options. This article will review Armstrong’s central air conditioning systems to help you determine which of their units is the right choice for your home.

Armstrong Air Conditioner Models

Armstrong offers six air conditioning units. These models range from 1.5 tons to 5 tons and have single-stage, two-stage, or variable capacity compressors.

They provide SEER ratings ranging from 14 to 20 SEER. While 20 SEER is not the best AC efficiency available on the market, it still offers fantastic energy cost reductions. Armstrong’s broad offering of various SEER ratings makes it easy to pick one for your climate and budget.

Armstrong prides itself on its innovation and product reliability.

Their MHTTM technology is a prime example of their innovative capabilities. The brand developed this fan system that pulls air evenly into each coil in the unit. This translates to all of the coils removing as much heat as possible, thus helping the unit’s efficiency.

The MHTTM technology integrates laced fins that extend contact time between the refrigerant and metal, which creates a more effective cooling system.

How To Determine Tonnage of Armstrong Air Conditioner

You can quickly determine the tonnage of your Armstrong air conditioner unit by examining the model number depicted on the data plate. Usually, the data plate is on the side of the condenser, which is also known as the outdoor unit.

Once you locate the model number, look at the end of the number. The number represents the unit’s nominal BTU in thousands and will be divisible by 6 or 12. A ton of air conditioning is equivalent to 12,000 BTU.

So, once you locate the two digits near the end of the model number, divide it by 12 to convert from BTUs to tons.

For example, if the model number were 8SHP57PD236P, the number would be 36. Divide that by 12, and you’re left with 3, meaning you have a 3-ton unit.

Armstrong’s older models may have a shorter number, but it is the same concept.

Here are some of the common ranges you will encounter:

  • 18 = 1.5 tons
  • 24 = 2 tons
  • 30 = 2.5 tons
  • 36 = 3 tons
  • 42 = 3.5 tons
  • 48 = 4 tons
  • 60 = 5 tons
