How Humidity Affects Air Conditioning and Heating Systems

When most people think of humidity, relative discomfort during the summer months comes to mind. How humidity affects air conditioning and heating systems, however, is a topic that is rarely discussed. If your home has an HVAC system, however, humidity is something worth talking about.

When Humidity Is Too High

An air conditioning system does more than cool your home — it removes the excess humidity from your home’s air supply. If there is too much humidity, your A/C system has to work harder to remove the excess heat and moisture in your home. Depending on the age of your A/C system, it may have to work harder than usual to balance out your home’s humidity; this results in a warmer home than you’d like due to the moisture in the air that your system was not able to remove. In addition to working harder, your system will be working for longer periods of time in order to produce results. This excess work results in wear and tear to your HVAC system as well as an increase in your utility bills.

While an HVAC system should be sizable enough to cool and heat your home effectively, a larger HVAC system is not always the answer in regards to resolving your home’s humidity issues. If your HVAC system is too large, it may think that it has cooled the room effectively and will turn off before it has had a chance to strip the room’s air of added moisture.

When Humidity Is Too Low

On the opposite end of the spectrum, during the winter months, a home’s humidity levels typically drop due to the simple fact that humidity levels drop outside. If your home’s humidity levels are too low, this can result in a colder living space. The heating system will then work overtime in an attempt to heat the home with little success. In fact, your home will likely feel colder as a result of too low humidity levels.

If your windows are foggy, if your air is clammy, or if you notice a musty smell in your home, chance are your humidity levels are too high.  In this case, a dehumidifier can work wonders. All in all, maintaining optimal humidity levels in the home is extremely important. If proper humidity levels are maintained, an HVAC system will not have to put in extra work and will save a homeowner time and money. Deciding on the right HVAC system for your home is crucial when it comes to making sure that it will cool and heat your home effectively.
