FAQs

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

Dunlap sits in the humid Sequatchie Valley, where summer dew-points often hover in the upper 60s and excess moisture lingers even in spring and fall. High indoor humidity fosters mold, dust-mites, musty odors, and can make a 75 °F room feel several degrees warmer. A whole-home dehumidifier removes this excess moisture before it circulates through your ductwork, creating a healthier living environment, protecting wooden floors and furnishings from warping, and allowing you to set the thermostat a few degrees higher without sacrificing comfort—often lowering cooling costs in the process.

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

We install the dehumidifier in-line with your return or supply ductwork, so it works in tandem with your HVAC equipment. When the humidistat senses moisture above your selected set-point, the unit draws air from the return side, extracts water, and sends the dry air back through the supply plenum to every room. Because it uses your existing ducts and blower, you get even humidity control throughout the house—no noisy portable units or buckets to empty. The system is wired to your HVAC thermostat or a dedicated wall control, so you can monitor and adjust humidity just as easily as temperature.

What does the installation process involve, and how long will it take?

A typical installation in Dunlap takes about one full work-day. Our NATE-certified technicians start by performing a load calculation to confirm sizing, then select an accessible spot near your air handler or furnace. We cut and seal a short section of duct to create the dehumidifier bypass, run a condensate drain to an approved location, and wire the unit to a dedicated 120 V or 240 V circuit. Finally, we program the humidistat, balance airflow, and test for proper operation. We protect floors, clean our workspace, and haul away all packaging—so the only thing you notice is drier, fresher air.

Will running a dehumidifier increase my energy bills?

The dehumidifier does draw electricity, but most homeowners see little to no net increase—and many see a decrease. Because drier air feels cooler, you can raise your AC set-point by 2-3 °F and still feel comfortable, saving up to 5 % per degree on cooling costs. The unit also allows your air conditioner to focus on temperature rather than moisture removal, reducing compressor run-time. In our experience, a properly sized dehumidifier in Dunlap often pays for itself in utility savings and reduced wear on the HVAC system.

What maintenance does a whole-home dehumidifier require after installation?

Maintenance is straightforward: (1) Replace or wash the internal air filter every 3-6 months, just as you do for your HVAC system. (2) Ensure the condensate drain remains clear; we treat it with enzyme tablets during annual tune-ups. (3) Once a year, our technician checks refrigerant pressures, cleans the evaporator coil, verifies electrical connections, and calibrates the humidistat. With these simple steps, most units last 12–15 years.

How do I know what size dehumidifier my home needs?

Proper sizing depends on square footage, ceiling height, infiltration rates, number of occupants, and local climate data. During our free in-home consultation, we perform a Manual J humidity load calculation and measure baseline indoor RH with calibrated instruments. Whole-home units are rated in pints per day—most Dunlap homes between 1,800 and 3,000 sq ft need a 70-95 pint model, but larger or more humid homes may require up to 130 pints. Correct sizing ensures efficient operation, even moisture removal, and lower operating costs.
