Can you add freon to an air conditioning unit? The amount of Freon or other refrigerant necessary to fill any size air conditioning unit depends on factors such as the size of the evaporator coil and whether the air conditioner is an all-in-one, self-contained exterior unit or a split system unit in which the condenser and compressor are outside and the air handler and coil are inside. The length of the lineset, the copper pipes which connect the outside condensing unit to the indoor evaporator coil on a split system unit, also affects the amount of Freon necessary to fill the unit, as does the diameter of the lineset tubing. The seasonal energy efficiency ratio of the unit also impacts the amount of Freon an air conditioner requires;

the higher the SEER rating, the larger the evaporating coil. The larger coil surface makes the air conditioner more efficient while increasing the amount of Freon needed to fill the unit. Freon, also known as R-22, is regulated by the Environmental Protection Agency, and only an EPA-certified technician can buy and handle it. How do you put Freon in a car?

Return to central air conditioner and refrigeration cycle from Gibson central air conditioners reviewOf course, there are more than 3 reasons that your 3 ton air conditioner isn't really 3 tons, starting with the fact that it's not 3 tons in weight. That unit refers to cooling capacity and harkens back to the days of ice. 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. David Butler wrote about two of these reasons in a guest post on ACCA's Manual S protocol for selecting HVAC equipment two years ago, and that's a great article for understanding some of the subtleties. 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%. That's closer to the actual conditions that most homes actually operate at than AHRI's conditions. Let's think about the temperature difference and see what effect that might have on the cooling capacity. 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. Is it harder to cool cooler air or warmer air?

The answer is the former. The lower the temperature goes, the harder it is to remove more heat from it. Just ask the folks at the Microkelvin Laboratory at the University of Florida, where they get about as close to absolute zero as is possible. 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. To find the answer here, you have to factor in the humidity levels, too. 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. In this case, we get a little of that lost capacity back here in Atlanta. 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 just harder for that refrigerant to give up those BTUs to air that's hotter. It's important to remember that the three reasons above don't have anything to do with poor design, installation, commissioning, or maintenance. Plenty of other factors related to those issues also affect capacity: These are not good reasons to oversize an air conditioner! The main thing to be aware of is that you need to know more than just the result of the Manual J cooling load calculation. 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. That's why Manual S, the equipment selection protocol, is so important. The thing is, though, that even with these issues that mostly reduce the capacity of your your air conditioner, most air conditioners still end up oversized.
