Gary Air warns Sarasota homeowners about rising indoor humidity as temperatures cool

Gary Air is urging Sarasota and Manatee County homeowners to monitor indoor humidity as Florida exits peak cooling season, saying moisture problems often worsen when air conditioners run less. The company says simple checks, the right fan setting and, in some homes, whole-home dehumidification can help prevent clammy air, odors and mold risk.

Why it matters: - Florida homeowners can see indoor humidity rise just as outdoor weather improves, creating a hidden comfort and health problem. - Indoor humidity above 60% can increase the risk of microbial growth and make homes feel cool but clammy. - Addressing moisture directly can reduce energy waste, limit wear on HVAC equipment and improve comfort without lowering the thermostat further.

What happened: - Gary Air is advising homeowners across Sarasota and Manatee County to start tracking indoor humidity as peak cooling season ends. - The company says the most common moisture problems in Florida homes often show up when the weather cools, not when summer heat is highest. - Gary Air is also pointing homeowners to practical steps such as checking humidity with an inexpensive hygrometer and reviewing HVAC settings and equipment performance.

The details: - Air conditioners dehumidify as a byproduct of cooling, because warm, moist air passes over a cold evaporator coil and the water condenses and drains away while the system runs. - From July and August into October, outdoor temperatures ease while dew points remain high, so the thermostat may satisfy quickly and the system spends less time removing moisture. - The Environmental Protection Agency recommends keeping indoor relative humidity below 60%, ideally between 30% and 50%. - Gary Air suggests placing one hygrometer in the main living area and another in a bedroom or closet on an exterior wall. - Oversized air conditioners can cool a home too quickly and stop before removing enough moisture, which can lead to short cycling, uneven temperatures and higher wear. - The thermostat fan setting matters. In AUTO mode, moisture is less likely to be re-evaporated into the living space. - Continuous fan operation can blow air across a coil that is still wet from the previous cycle and send that moisture back into the home. - The Florida Solar Energy Center found that fan operation can raise indoor humidity enough that people lower the thermostat just to feel drier. - ENERGY STAR guidance recommends AUTO rather than ON in humidity-sensitive situations and advises disabling supply fan overrun where moisture is a concern. - A whole-home dehumidifier can remove moisture directly when a house stays above 60% humidity through cooler months. - Other moisture sources worth checking include return-side duct leakage, a dirty filter or coil, and condensate drainage problems. - Gary Air installs and services dehumidifiers and provides duct cleaning, ventilation work, HEPA filtration, UV purification, cooling and heating service. - The company can be reached at 941-957-0049. - Gary Air is a veteran-owned, locally operated HVAC company serving Sarasota County, Manatee County and nearby areas. - The company is located at 1891 N East Ave, Sarasota, FL 34234.

Between the lines: - The advice reflects a common Florida HVAC problem: a system can seem to be doing fine because the home feels cooler, while indoor moisture quietly climbs. - The focus on humidity control suggests that comfort complaints in shoulder season may be solved less by lower temperatures and more by better moisture management. - The guidance also points to a broader HVAC message: bigger equipment is not always better in a humid climate.

What's next: - Homeowners are likely to notice humidity changes over the next several weeks as cooling runtime drops. - Households with persistently high readings may need a service check, better airflow, corrected duct issues or a dehumidifier. - Gary Air is positioning itself to handle those repairs, maintenance calls and indoor air quality upgrades as the season shifts.
