The indoor coil is fabricated from copper tube and aluminum fins and is located inside the unit for protection against damage. The outdoor coil is internally mounted on the top tier of the unit.Low sound ratings ensure a quiet indoor and outdoor environment with sound ratings as low as 72dBA.Easy to service cabinets provide easy 3 panel accessibility to serviceable components during maintenance and installation. The basepan with integrated drain pan provides easy ground level installation with a mounting pad. A nesting feature ensures a positive basepan to roof curb seal when the unit is roof mounted. A convenient 3/4-in. (19.05 mm) wide perimeter flange makes frame mounting on a rooftop easy.Dehumidification FeatureThis unit has independent fan speeds for low stage cooling and high stage cooling. In addition, 208/230 VAC models have thefield-selectable capability to run an enhanced dehumidification (’DHUM’) speed on high stage cooling (as low as 320CFM perton).

Coupled with the improved dehumidification associated with low stage cooling, the DHUM speed allows for a complete dehumidification solution independent of cooling stage. The dehumidification control must open the control circuit on humidity rise above the dehumidification set point.

I'm also not talking about any of the multitude of reasons having to do with improper design, faulty installations, or lack of maintenance, topics that I discuss plenty in this space. No, today I'm going to tell you that your 3 ton (or 2 ton or whatever size you have) air conditioner may not be what you think it is even when everything's designed, installed, commissioned, and maintained perfectly. So, what are these 3 reasons?

The first reason is that when we talk about air conditioner capacity, we're usually giving the nominal size. A 3 ton air conditioner has a nominal capacity of 36,000 BTU per hour, but the actual rating using the operating conditions specified by AHRI is rarely the same as the nominal capacity. For example, the AC shown in the AHRI certificate below is a 3 ton air conditioner (36,000 BTU/hr) with an actual capacity of 2.8 tons (34,000 BTU/hr). As David Butler discussed in his article on Manual S, AHRI ratings are done for an indoor dry bulb temperature of 80° F and indoor wet bulb temperature of 67° F. ACCA recommends using an indoor design temperature (dry bulb) of 75° F and relative humidity of 50%. Which way do you think it would go if we bring cooler air into the air conditioner than it was rated for? Well, let's frame that a little differently. If it's harder to cool air at 75° F than air at 80° F, then that means the 2.8 ton air conditioner above isn't even going to be 2.8 tons.

As David wrote, it's a moving target, but the net result of AHRI's operating conditions is that your air conditioner's capacity is lower than it's rated (unless you keep the thermostat at 80° F or higher). AHRI uses 95° F as its outdoor test temperature, so if your outdoor cooling design temperature differs from that, your AC capacity will again vary from the AHRI rated capacity. Our design temperature is 92° F, which means that the air conditoner has an easier job of dumping heat into the outside air than it would if it had to dump the heat into 95° F air. If you live in Tucson, Arizona, with a design temperature of 103° F, however, your 3 ton air conditioner has now dropped in capacity again. It's important to remember that the three reasons above don't have anything to do with poor design, installation, commissioning, or maintenance. A Manual J report may say you need a 3 ton air conditoner, but for the three reasons above, you might really need to install a 3.5 ton unit.
