Have you noticed a thick, muggy feeling in the air when your AC is on? Is more condensation present on your windows and mirrors? Maintaining a healthy humidity level in your home is essential to your health and comfort. If your AC is producing excess moisture, the system is likely malfunctioning. Here are a few of the reasons your AC unit may be increasing your humidity level.
Wrong Thermostat Setting
Air conditioners naturally remove moisture from the air as they cool your home. If your thermostat is set to ON rather than AUTO, your blower will continue to circulate air even when the AC unit isn’t cooling the home. This can be especially detrimental to your indoor comfort if you live in an area with a high humidity level. Instead of leaving your blower on constantly, switch your settings to AUTO and rely on ceiling fans or a ventilation system instead.
Frozen Evaporator Coils
Once your air filter gets dirty or you begin to experience water leaks, you’re at a higher risk of dealing with frozen evaporator coils. These coils are responsible for cooling the refrigerant so that it can continue to absorb heat from the home. Once these coils are frozen, you’re more likely to see humidity issues as well as higher energy bills. Turn your air conditioner off to avoid further damage and look for anything that may be affecting airflow in the system. An expert technician can replace your filters and fix any water leaks in your AC unit.
Dirty Condenser Coils
You may also experience higher humidity levels if your condenser coils become dirty. As the refrigerant in your AC unit cools the home, it also gathers heat that needs to be released outside. Dirt, dust and debris can cover the outdoor unit, which will obstruct the unit’s airflow. Your air conditioner will be unable to effectively remove excessive humidity from your home. Fortunately, this issue can be easily corrected by keeping your outdoor unit clean and clear of any obstructions.
A clogged drain line or cracked overflow pan can quickly cause water issues in the home. AC units constantly create moisture as they cool your home. This water should be safely carried out of your unit via the drain line, which can easily become clogged with mildew and debris. If water is lingering in your system or leaking into the home, your humidity level will increase over time. The best way to minimize AC unit leaks is by relying on professional HVAC services.
Your ductwork plays a significant role in your home’s indoor comfort. As your ductwork ages, it’s more likely to break down, tear or corrode. This allows warm air into your ductwork, which can create condensation and increase your humidity level. If you’ve recently moved into a new home and notice moisture issues, you should have your ductwork professionally appraised to ensure it’s correctly zoned. If additional rooms or spaces have been given ducts, this structural change may have affected your HVAC system’s ability to efficiently cool the home.
Outdated AC Unit
It’s possible that your AC unit may be too old to keep up with your home’s cooling needs. Older systems lose efficiency over the years, affecting how much cool air and temperature control they can provide. If you’ve noticed an increase in maintenance needs as well as higher utility bills, your system may need to be replaced with a new and improved model. Changing out your AC unit before it completely breaks down can save you money and protect you against a potential HVAC emergency. Consult with an expert technician to determine the best way to keep your home comfortable.
