FAQs

What are the main benefits of installing a whole-home dehumidifier in Shelbyville?

Shelbyville’s warm, humid summers often push indoor relative humidity well above the recommended 45–50 % range. A properly sized whole-home dehumidifier removes excess moisture from every room, helping prevent mold growth, dust-mite infestations, musty odors, and wood-warping. Lower humidity also lets you dial back the air-conditioner by 2–3 °F without sacrificing comfort, which can trim energy bills by up to 15 %. Homeowners report fewer allergy and asthma flare-ups, crisper indoor air, and longer HVAC equipment life because the A/C no longer has to over-work to wring out humidity.

How does a whole-home dehumidifier connect to my existing heating and air-conditioning system?

We install the dehumidifier in line with your home’s supply or return ductwork—usually near the air handler or furnace—in the same mechanical room. A dedicated condensate drain line directs the collected water to a floor drain or condensate pump. The unit is wired to your HVAC control board or to a stand-alone humidistat so it can run independently of the air-conditioner whenever indoor humidity exceeds the chosen setpoint. Because the air is already conditioned by your HVAC system, the dehumidifier can operate quietly and efficiently without altering your heating or cooling airflows.

What size dehumidifier do I need for my Shelbyville home, and how is it determined?

Sizing is based on square footage, ceiling height, typical occupancy, and moisture-generating activities such as cooking, showering, or owning a basement. We perform an on-site load calculation that measures both the latent (moisture) and sensible (temperature) gains in your home. For most Shelbyville residences, capacities range from 70 to 120 pints per day. Oversizing wastes energy and can over-dry the air, while undersizing will short-cycle and fail to control humidity on peak days—so a tailored load calculation is crucial.

How long does professional installation take, and will it disrupt my household?

A standard whole-home dehumidifier installation takes 3–5 hours. Our technicians protect flooring, isolate the work area, and shut off power to the HVAC equipment before modifying ductwork. Because the unit is installed within existing ducts, only brief interruptions to heating or cooling occur. Most homeowners experience minimal noise or dust, and the system is fully operational the same day. We provide a walk-through to demonstrate settings, filter changes, and the condensate drainage path before we leave.

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

Maintenance is simple and can be tied to your HVAC service schedule. 1) Replace or clean the dehumidifier’s MERV-rated air filter every 6 months (more often if you have pets or allergies). 2) Inspect and clear the condensate drain annually to prevent clogs and water backups. 3) Have the refrigeration coil and blower wheel cleaned every 2–3 years to maintain efficiency. During your seasonal HVAC tune-ups, our technicians can perform these tasks, check refrigerant pressure, and verify the humidistat calibration.

How much does a whole-home dehumidifier installation cost in Shelbyville, and are rebates available?

Total installed cost typically ranges from $1,800 to $3,200, depending on capacity, duct modifications, and whether a condensate pump is required. High-capacity ENERGY STAR® models may qualify for TVA’s local energy-efficiency rebates or federal tax credits under the Inflation Reduction Act—up to 30 % of the equipment cost, capped at $600. We provide an itemized quote up front and handle all rebate paperwork so you receive the maximum savings.
