In the humid subtropical climate of Birmingham, AL, homeowners and business owners are constantly battling high moisture levels. While we often think of our HVAC systems purely for heating and cooling, their impact on indoor humidity is arguably just as critical for comfort, health, and property preservation. At Plus One Heating, Air & Plumbing, we understand that managing the humidity inside your home is key to creating a truly comfortable and healthy living environment. Failing to properly control indoor humidity can lead to sticky, uncomfortable air in the summer and dry, irritating air in the winter, all while inviting issues like mold growth or damage to wood furnishings. Our expertise ensures that when we install, maintain, or repair your system, we’re addressing both temperature and moisture control.
Summer Humidity: The Dehumidification Role
Birmingham summers bring high heat coupled with high humidity, making the air feel much heavier and warmer than the thermometer indicates. Your air conditioning unit is your primary defense against this moisture.
How Your AC Dehumidifies
When your air conditioner runs, it does more than cool the air; it actively dehumidifies it. Warm, moist air from your home passes over the cold evaporator coil. As the air cools below its dew point, moisture condenses out of the air and collects as water droplets on the coil. This water then drains away through the condensate pan and line. This process is why you see water dripping from your unit outside. A properly functioning AC unit should maintain indoor humidity levels between 40% and 55% during the cooling season, which is considered the ideal comfort zone.
Common Dehumidification Issues
If your home feels clammy or sticky, even when the temperature is cool, your AC may be failing to properly remove moisture. Two primary culprits are often at play:
Oversized Systems: If an AC unit is too large for the space, it cools the air quickly and satisfies the thermostat before it has run long enough to adequately remove moisture. This "short cycling" leaves the air cool but saturated with humidity. Correct system sizing is a fundamental service that Plus One Heating, Air & Plumbing prioritizes during installation.
Dirty Coils or Clogged Drain Lines: A clogged drain line prevents condensate water from escaping, causing the unit to retain moisture and potentially leading to leaks or water damage. Dirty evaporator coils reduce the efficiency of the cooling process, hindering the unit's ability to condense moisture effectively. Regular maintenance through our Plus 1 Club ensures these issues are caught and addressed promptly.
Winter Humidity: The Need for Humidification
While the summer fight is against excess moisture, winter brings a different challenge. Running a furnace or heat pump in the winter often dries out the air significantly. Since cold air naturally holds less moisture than warm air, continuously heating this dry air can result in uncomfortable indoor conditions.
The Effects of Low Humidity
If your indoor humidity drops below 30%, you and your home can suffer. You may experience dry, itchy skin, irritated sinuses, and static electricity shocks. The dry air can also pull moisture from wood, causing wood floors, trim, and furniture to crack or separate.
Solutions for Winter Dryness
For homes in the Birmingham area struggling with excessively dry air in the winter, Plus One Heating, Air & Plumbing recommends the installation of a whole-house humidifier. Unlike portable units, a whole-house humidifier is integrated directly into your HVAC system. It delivers a consistent level of moisture to the entire home, ensuring the ideal 40% to 55% humidity level is maintained year-round, regardless of how cold it gets outside. This holistic approach to humidity control is far more effective than trying to manage individual rooms with small, portable humidifiers.
Whole-House Solutions for Year-Round Balance
For true control over your indoor environment in Alabama's fluctuating climate, dedicated humidity control is the key. While the AC cools, a specialized dehumidifier can be integrated into your existing ductwork to handle moisture removal independently, which is especially useful on mild but muggy days when you don't need cooling.
