Columbus Air Conditioning Question: Does Humid Air Affect How My AC Runs?
You’ve probably heard a dozen times that humidity is removed by your air conditioner. Unfortunately, the common assumption is that there is no inherent cost in allowing humidity to persist in your home. But did you know it costs significantly more to remove humidity from the air in your Columbus air conditioner than with a dehumidifier? Here’s why.
First consider the amount of energy it takes to raise the temperature of water by one degree – one BTU (a decent amount). But did you know it requires another 10 BTUs to change water from liquid to steam? So, imagine how much energy it takes to condense water vapor from the air (in the form of humidity) into a liquid. This is what your air conditioner does whenever it processes humid air. It takes about 1,050 BTUs to condense one pound of moisture in the air into liquid.
The cost of running your air conditioner strictly for dehumidification can be huge, especially considering the fact that humidity is heaviest in the morning and evening when you probably don’t need your air conditioner running anyways (at least not early and late in the summer). Imagine the cost difference if you used a dehumidifier to remove 150 or more pounds of moisture per week and an air conditioner when needed just to remove 15-20.

Negative Impact on How it Runs
Another thing to consider is that humidity can actually put an extra burden on your air conditioner. While the system is designed to remove that liquid from the air and get rid of it through the cooling coil and condensate drain, every extra minute the system is running is a bigger burden on it. Of course it will do its job for a few years, but the extra running time will add up, not only on your electricity bill, but eventually on the machine itself.
This added pressure will result in an eventual breakdown and require an early replacement. The easiest solution to prevent this is to purchase a dehumidifier. These run at a fraction of the energy level of most Columbus AC systems and work extremely well to remove humidity from your home. In fact, most air conditioners will only remove humidity after 20-30 minutes of continuous operation. For short cooling cycles, they may not even dehumidify the house. So a dehumidifier ensures higher levels of comfort all at a lower cost.
