FAQs
Why should I add a whole-home dehumidifier to my existing HVAC system in Loudon?
Loudon experiences warm, humid summers and shoulder seasons in which indoor moisture can stay high even when the air conditioner is running. A whole-home dehumidifier removes excess humidity that your air conditioner alone may not handle, preventing mold growth, musty odors, condensation on windows, and dust-mite activity. Lower indoor humidity also makes you feel cooler at higher thermostat settings, which can reduce your summer energy bills by 5–10 %.
Will the dehumidifier work during both heating and cooling seasons?
Yes. Unlike a traditional air conditioner, which only removes moisture when it is actively cooling, a dedicated whole-house dehumidifier can operate independently of the furnace or air-conditioner cycles. In the summer it supplements the A/C, and in mild spring or fall weather it keeps humidity in check even when you’re not running the A/C. During winter, the control system prevents the unit from over-drying your home, maintaining the recommended 30–50 % relative humidity.
How is a whole-house dehumidifier integrated into my existing ductwork?
Our technicians install the dehumidifier in a bypass or dedicated return-to-supply configuration. This means a small branch duct pulls humid air from the return plenum (or a central area of your home), passes it through the dehumidifier, and sends the dried air back into the supply plenum so it is distributed evenly through the HVAC system. The unit has its own condensate drain line and can be wired to your existing smart thermostat or a separate humidistat for automatic control.
What size dehumidifier does my Loudon home need?
Sizing is based on your home’s square footage, typical indoor moisture load, existing HVAC capacity, and building envelope tightness. A rule of thumb is 30–35 pints per day for every 1,000 sq ft, but we always perform a full load calculation using ACCA Manual J and the AHRI dehumidifier sizing chart. For most Loudon residences, recommended capacities range from 70 to 120 pints per day. Proper sizing ensures efficient moisture removal without excessive run time or short-cycling.
How much maintenance will the dehumidifier require after installation?
Maintenance is minimal. You should replace or rinse the dehumidifier’s air filter every 3–6 months (more often if you have pets or allergies) and confirm the condensate drain line is clear. During your annual HVAC tune-up, our technician will clean the internal coils, check refrigerant pressures, inspect electrical connections, and verify humidistat calibration. Most whole-house dehumidifiers have a service life of 10–15 years when maintained properly.
What does installation cost in Loudon, how long does it take, and are rebates available?
A typical whole-home dehumidifier installation in Loudon costs between $2,200 and $3,500, depending on the unit’s capacity, duct modifications required, and any smart controls you select. The work is usually completed in one day with no disruption to drywall or flooring. Loudon Utilities Board and TVA periodically offer rebates of $150–$300 for ENERGY STAR certified dehumidifiers, and federal tax credits under the Inflation Reduction Act may cover 30 % of the installed cost (up to $600). We’ll help you file the paperwork so you get every incentive you qualify for.
