Evansville HVAC FAQs
How does Ohio River humidity affect cooling in Evansville?
High moisture loads make short cooling cycles feel clammy. Longer, lower-speed operation and clean coils remove more moisture, which helps rooms feel cooler at the same setpoint.
What should I do before a same-day service visit?
Open all supply and return grilles, clear access to the air handler, thermostat, panel, and outdoor unit, and note when symptoms happen. If a coil is iced, set cooling Off and fan On until a technician arrives.
Which thermostat features actually help in our climate?
Look for dehumidify on cool, adaptive recovery, and staging control. These features favor steady operation that manages humidity and reduces swings.
Do I need permits when replacing HVAC equipment around Vanderburgh County?
Most equipment replacements require permitting and inspections for electrical and mechanical work. A+ Derr Heating & Cooling handles the paperwork and coordinates inspections.
What SEER2 rating is a good fit for Evansville summers?
Mid to high SEER2 systems paired with sealed ducts, verified airflow, and smart controls typically provide a strong balance of comfort and cost.
Why do some rooms stay warm even after a repair?
Duct balance and return paths may need attention. Adding returns to closed bedrooms, correcting undersized runs, and setting the right blower speed often evens out temperatures.
Are heat pumps practical here or should I stick with a furnace and AC?
Heat pumps work well for cooling and shoulder-season heating. Many homes stay with a dual-fuel setup that uses the heat pump most days and the furnace during colder snaps.
What maintenance tasks make the biggest difference before peak heat?
Replace filters on time, keep the outdoor coil clear of cottonwood and grass clippings, and make sure the condensate drain is flowing. A spring tune-up catches issues before a heat wave.
How can I reduce HVAC noise that carries through walls or patios?
Level the outdoor unit, maintain clearances, add vibration pads, and check that indoor returns are sized correctly. Flexible connectors and proper duct supports also help.
What should I check if the system will not start after a storm?
Give the thermostat and controls a few minutes for built-in delays, then check breakers and the outdoor disconnect. If a breaker trips again or the fan hums without spinning, power the system off and schedule service.
