Is High Humidity Affecting Your HVAC Performance?
Is your home feeling a little too muggy these days? If you live in Newnan, chances are you've noticed that the humidity has been particularly high lately. In recent years, high humidity levels have become more common, especially during summer. And while many people believe that high humidity is simply an uncomfortable annoyance, it can have a serious impact on your home's HVAC performance. Read on to learn more about how humidity affects your HVAC and tips from HVAC experts in Newnan to mitigate the effects.
How does humidity affect your HVAC System?
High humidity can cause several problems for your HVAC system, including:
Increased stress on your AC unit: When the humidity level is high, the air is thicker and contains more moisture. This increased moisture makes it more difficult for your HVAC system to cool and dehumidify the air. As a result, your system will use more energy and will be less effective at cooling your home. In addition, high humidity can cause problems with your home's insulation, leading to increased energy usage and higher utility bills. In fact, our HVAC maintenance professionals in Newnan estimate that when relative humidity was increased by 20%, HVAC performance decreased by as much as 15%.
Compromised indoor air quality: When the humidity levels are high, the air is more saturated with water molecules. This means there is a higher likelihood of the air holding onto contaminants, such as dust, pollen, and smoke. This can lead to poor indoor air quality, which can cause allergies, asthma, and other respiratory problems. Additionally, high humidity can cause your HVAC system to work harder in order to cool or heat the air, which can lead to higher energy costs.
Is your HVAC performance affected by high humidity?
There are several signs that can indicate your HVAC performance is being impacted by high humidity levels. These are some of the most common that our HVAC experts from Newnan highlight:
- The unit running for longer periods of time in order to achieve the desired temperature
- The unit's energy usage increasing
- The unit's cooling output decreasing
- Moisture appearing on windows or walls

What You Can Do to Help Your HVAC Unit cope With High Humidity
There are a few things you can do to help your HVAC system deal with high humidity, including:
- Opening doors and windows: This will help ventilate your home and get rid of some of the excess moisture in the air. Just be sure to close them again once your AC unit has turned on.
- Using a dehumidifier: A dehumidifier will help remove moisture from the air, making it easier for your AC unit to do its job. Just be sure to empty the dehumidifier regularly so it doesn't overflow.

- Using fans: Fans will help circulate the air in your home and make it feel cooler without having to lower the temperature on your AC unit.
- Sealing leaks: If there are any leaks in your home, now is a good time to seal them up. This will help keep humid air from coming in and making things worse.
- Regular maintenance: In order for your unit to run smoothly in high-humidity environments, it's important to keep up with regular maintenance. This includes cleaning the coils and filters regularly, as well as checking the refrigerant levels. An HVAC maintenance expert in Newnan can help keep your HVAC unit in good condition and ensure that it runs efficiently, even when the humidity is high.
High humidity can take a toll on your HVAC system, but there are things you can do to help mitigate the effects. By opening doors and windows, using a dehumidifier, using fans, sealing up any leaks and regular maintenance, you'll help keep your HVAC system running smoothly all year long.
