FAQs

Why should I add a dehumidifier to my existing HVAC system in Tullahoma’s climate?

Middle Tennessee experiences long stretches of warm, humid weather. Excess indoor humidity (anything above 50–55 %) can make your home feel muggy, encourage mold and dust-mite growth, and force the air conditioner to run longer than necessary. A whole-home dehumidifier removes moisture independently of your AC cycle, helping you stay comfortable at a higher thermostat setting, protecting furnishings and building materials, and lowering the risk of allergens and musty odors.

Will a whole-home dehumidifier work with my current furnace/air-handler and ductwork?

In most cases, yes. We install the dehumidifier in parallel with your supply-return ductwork so it can treat all the air that moves through the system. During our free in-home evaluation we confirm the size of your equipment, available static pressure, and electrical capacity to be sure the dehumidifier integrates properly. If minor duct modifications or an additional return grille are needed, we’ll outline those changes up front.

How is a dehumidifier installed, and how long does the process take?

After sizing the unit, our technicians mount the dehumidifier next to your air handler or in the attic/basement, tie it into the supply and return plenums with insulated flex or hard pipe, run a dedicated condensate drain to the exterior or floor drain, wire the control to your existing thermostat or provide a new humidistat, and add a 120-V or 240-V electrical connection. A typical retrofit takes 4–6 hours and rarely requires drywall or finish repairs.

What impact will the dehumidifier have on my energy bills?

The unit draws power while it removes moisture, but because dry air feels cooler, most homeowners raise their thermostat by 2–3 °F and reduce AC runtimes. Field studies show a net energy change ranging from a slight increase to a 10 % reduction in summer cooling costs. We install ENERGY STAR® rated equipment and can help you calculate expected operating costs based on local Tullahoma utility rates.

What maintenance is required after installation?

Maintenance is straightforward: replace or clean the dehumidifier’s MERV-rated filter every 6–12 months, flush the condensate line annually, and have the refrigeration coil checked during your regular HVAC tune-up. We include the first-year service visit at no charge and can bundle future dehumidifier inspections into our semi-annual Comfort Club plan.

Is the dehumidifier noisy, and where will it be located?

Whole-home units are designed for quiet operation (45–55 dB). Because they sit in a mechanical space—attic, basement, crawl space, or next to the indoor air handler—most homeowners never notice them running. When attic or crawl-space access is limited, we can install the unit on vibration-isolating pads by the furnace and use acoustic ducting to keep sound levels minimal in living areas.
