Keeping Cool in a Humid Ohio Summer
Short answer: change the filter, keep the outdoor unit clear and book a spring tune-up. In humid weather, an AC that removes moisture well matters as much as one that cools fast.
Request an HVAC technicianSpring check
Have coils cleaned and refrigerant checked before the first heat wave.
Filters
Change filters regularly in summer too.
Outdoor unit
Keep grass, leaves and shrubs at least two feet away.
Humidity
Oversized units leave the house cool but clammy.
Basements
A dehumidifier helps in damp basements.
Thermostat settings
Raise the setting a few degrees when you're away.
Frozen lines
Ice on the lines means turn the AC off and call a technician.
Drain lines
Clogged condensate drains can overflow onto the furnace.
Window units
Homes with boilers often rely on window units until ductless is added.
Storms
Summer storms can trip breakers; reset once and call if it trips again.
Ceiling fans
Ceiling fans let you raise the thermostat a couple of degrees and still feel comfortable, which takes some load off an older AC.
Upstairs rooms
Second floors and finished attics run hot in older homes with ductwork sized for heating. A ductless head can even things out.
