FAQs
Why do homeowners in Cowan need a whole-home dehumidifier?
Cowan sits in a humid region of Tennessee where outdoor moisture routinely seeps indoors, raising relative humidity above the ideal 30–50 % range. Excess humidity encourages mold growth, dust-mite populations, musty odors, and that sticky, uncomfortable feeling even when the thermostat is set correctly. A whole-home dehumidifier removes the moisture load before it circulates through your living spaces, improving air quality, protecting wood floors and furnishings, and allowing your air conditioner to cool more efficiently.
How is a whole-home dehumidifier installed in my existing HVAC system?
Our technicians mount the dehumidifier in line with your home’s supply or return ductwork, typically near the air handler or furnace. A dedicated bypass duct draws humid air into the unit, where moisture condenses on a cooled coil and drains safely to a nearby condensate line or sump pump. Dry air is then delivered back into the supply plenum so every room benefits. Because the system ties into existing ducts and uses its own control board or your smart thermostat, you gain seamless, quiet operation without bulky portable units.
What size dehumidifier does my home require?
Sizing is based on square footage, ceiling height, infiltration levels, and the number of occupants and moisture-producing activities (cooking, showers, laundry). During your free in-home assessment, we perform load calculations that follow ACCA Manual D guidelines and recommend a unit rated in pints per day—most Cowan homes need 70–120 pints. Choosing the right capacity ensures the dehumidifier cycles properly, avoids short-cycling, and attains the target humidity without wasting energy.
Will a whole-home dehumidifier increase my energy bills?
Modern whole-home units are ENERGY STAR® certified and draw about the same power as a window AC. By taking latent heat (moisture) out of the air, they let your air conditioner run shorter cycles and at a higher temperature setting—many customers raise the thermostat 2–3 °F and still feel cooler. The result is little to no net increase in electricity costs, and some households actually see lower summer utility bills.
How often does my dehumidifier need maintenance?
Routine care is simple. Replace or clean the unit’s air filter every 6–12 months, pour a cup of diluted vinegar down the condensate drain each season to prevent algae buildup, and have the coil and blower inspected annually during your HVAC tune-up. Our Comfort Club members receive these inspections automatically, keeping the dehumidifier’s 5-year manufacturer warranty intact and performance at peak levels.
Will installing a dehumidifier affect my HVAC warranties or performance?
No. All equipment we install is manufacturer-approved for integration with forced-air systems. In fact, reducing indoor humidity eases the workload on your air conditioner and helps the heat exchanger in your furnace avoid corrosion, potentially extending equipment life. We register the new dehumidifier and document the installation so your existing HVAC warranties remain valid, and we back our workmanship with a 1-year labor guarantee for added peace of mind.
