FAQs

Why is a whole-home dehumidifier important for homes in Crab Orchard?

Crab Orchard’s warm, rainy summers keep average relative humidity above 70 %, which can leave homes feeling clammy, promote mold growth, and warp wood floors and furniture. A whole-home dehumidifier removes excess moisture from every conditioned room, helping you stay comfortable at a higher thermostat setting, protecting the structure of the house, and improving indoor air quality by discouraging dust mites, mildew, and musty odors.

How does a whole-home dehumidifier work with my existing heating and air-conditioning system?

The unit is installed in-line with your supply or return ductwork—usually at the air handler—so the same fan that circulates heating and cooling also pulls humid air through the dehumidifier. The moisture condenses on an internal coil, drains away through a dedicated condensate line, and the dried air is sent back through the ducts. A built-in humidistat automatically turns the unit on only when humidity rises above your set point, so operation is seamless and hands-free.

What is involved in the installation process and how long does it take?

Our licensed Crab Orchard HVAC technicians begin with a free in-home evaluation to size the dehumidifier (typically 70–120 pints per day). On install day we: 1. Isolate power to the HVAC system. 2. Cut in a mounting location on the return or supply plenum. 3. Attach vibration-isolating hangers or a platform, then seal all duct joints. 4. Run a PVC condensate line to a floor drain or condensate pump. 5. Wire the humidistat to your thermostat or a dedicated wall control. 6. Test for proper airflow, refrigerant pressures, and drainage. The job generally takes 4–6 hours and there is minimal disruption to drywall or finished surfaces.

How much does a professionally installed whole-home dehumidifier cost in the Crab Orchard area?

Pricing depends on capacity, controls, and any needed duct modifications, but most homeowners spend $2,000–$3,500 for a complete turn-key installation. This includes the dehumidifier unit, condensate pump if required, labor, all permits, and a one-year workmanship warranty. We provide written estimates up-front and offer financing plans so you can spread the investment over manageable monthly payments.

What maintenance does the dehumidifier require after installation?

Whole-home dehumidifiers are low maintenance. Plan on: • Cleaning or replacing the internal MERV-rated filter every 6–12 months (more often if you have pets or allergies). • Flushing the condensate line annually to prevent algae buildup. • Verifying the humidistat calibration during your regular HVAC tune-up. We can bundle dehumidifier service with your spring or fall HVAC maintenance visit to keep everything running efficiently without extra appointments.

Will operating a dehumidifier increase my energy bills?

A typical 70-pint Energy Star certified dehumidifier draws around 5–6 amps—roughly the same as a small window AC—but because drier air feels cooler, most homeowners raise the thermostat 2–3 °F. The reduced air-conditioning runtime usually offsets most, if not all, of the dehumidifier’s electrical use. In addition, controlling humidity extends the life of HVAC equipment and can prevent costly moisture-related repairs, making the system a smart long-term investment.
