FAQs

Why should I add a whole-home dehumidifier to my existing heating and air-conditioning system in Blountville?

Blountville’s warm, humid summers often push indoor relative humidity well above the 50 % comfort target. Excess moisture encourages mold, dust-mite growth, musty odors, and can make the air feel several degrees hotter, forcing your A/C to run longer. A whole-home dehumidifier tied into your ductwork removes this moisture before it circulates through the house, improving comfort, protecting furnishings and structural materials, and allowing you to raise the thermostat 2–3 °F without sacrificing comfort—cutting cooling costs by up to 10 %.

Can a dehumidifier be connected to my current ductwork without major remodeling?

Yes. Most modern whole-home dehumidifiers are designed for retrofit applications. We install a small supply and return bypass into your existing duct trunk (often near the air handler), so the unit draws humid air in, dries it, and sends it back through the main supply. Because the cabinet is similar in size to a media filter or small air handler, installation rarely requires new ducts or structural changes—just proper placement, a dedicated 120 V outlet, and a condensate drain or pump.

How do you determine what size dehumidifier my Blountville home needs?

During our free in-home assessment we measure square footage, ceiling height, insulation levels, current humidity readings, and average infiltration rates. We also consider lifestyle factors—number of occupants, pets, frequency of cooking or showering, and basement or crawl-space moisture. Using ACCA Manual H guidelines, we match those numbers to a unit’s moisture-removal capacity (pints per day). Most 2,000–3,000 ft² Blountville homes require a 70–95 pint model; larger or leakier houses may need 120 + pints.

Will running the dehumidifier increase my energy bills?

A dehumidifier does draw electricity (typically 4–8 amps while running), but it lets your air conditioner cycle less often and at a higher setpoint. Independent studies show that in the Tennessee Valley climate, the net result is usually a 5–15 % reduction in total summer HVAC energy use. The unit’s high-efficiency scroll compressor and EC fan motor keep operating costs low, averaging $25–$40 per month in peak season for a 2,500 ft² home.

How long does installation take and will my HVAC be out of service?

Most projects are completed in one workday—about 4–6 hours. We shut off the air handler only long enough to cut in the two 6-inch collars and seal the connections (roughly 60–90 minutes). Your HVAC is fully operational the same evening. All work complies with local Blountville mechanical codes, and we pull any required permits.

What ongoing maintenance or warranty coverage is included?

Whole-home dehumidifiers are low-maintenance. Simply rinse or replace the air filter every 6 months and ensure the condensate drain remains clear. During your annual HVAC tune-up we check refrigerant pressures, clean the coil, and verify humidity set points at no extra charge. Most brands we install carry a 5-year parts warranty and a 1-year labor warranty, which we extend to 3 years for Blountville residents enrolled in our Comfort Club service plan.
