FAQs
Why is a whole-home dehumidifier important in Chattanoogaâs climate?
Chattanooga sits in the Tennessee River Valley where average outdoor relative humidity hovers between 70 â 90 % for much of the year. Warm, moisture-laden air infiltrates homes, raising indoor humidity above the ideal 45-50 % range. Excess water vapor can make rooms feel stuffy, drive up air-conditioning costs, and promote mold, mildew, and dust-mite growth. A whole-home dehumidifier tied into your HVAC ductwork automatically removes pints of moisture every hour, keeping humidity in check even during muggy spring and summer months.
How does a dehumidifier integrate with my existing heating and air-conditioning system?
Our technicians install the dehumidifier in the return-air plenum or a dedicated bypass loop. The unit draws moist air from your home, cools it to condense water vapor, drains the condensate to a safe outlet, then reheats and returns the drier air to your supply ducts. The dehumidifier is wired to your HVAC blower so it can operate independently of heating or cooling cycles, and a wall-mounted humidistat lets you select your target RH just like a thermostat sets temperature.
What size dehumidifier does my Chattanooga home need?
Sizing is based on several factors: square footage, ceiling height, typical infiltration rates in older vs. newer construction, the number of occupants, and moisture-producing activities such as cooking and showering. Most area homes require units rated between 70 and 130 pints per day, but our load calculation (following ACCA Manual LLH guidelines) will determine the right capacity so the system cycles properly without short-running or overworking.
Will a dehumidifier help with mold, allergens, and comfort?
Yes. Mold spores and dust mites thrive when RH is above 60 %. By maintaining humidity around 50 %, a whole-home dehumidifier drastically slows biological growth, reducing musty odors and allergy triggers. Lower RH also lets perspiration evaporate more readily from your skin, so you feel cooler at higher thermostat settingsâoften allowing a 2-3 °F temperature increase without sacrificing comfort and saving on A/C costs.
What is the installation process and how long does it take?
A standard installation usually takes 4-6 hours. After confirming capacity and location, we cut access into the ductwork, set the dehumidifier on vibration-isolating pads or hang it from joists, connect supply/return collars, plumb the condensate line with a trap and overflow safety switch, wire the control circuit to the air handler, and program the humidistat. Before we leave, we check airflow, verify drain operation, and demonstrate settings to the homeowner.
How much does it cost and will it save energy?
In the Chattanooga market, professionally installed whole-home dehumidifiers range from $2,000 to $3,500 depending on capacity and duct modifications. While the unit adds a small electrical load (about the same as a window A/C), homeowners typically set their main air conditioner 2-4 °F higher, cutting compressor run time. Studies show total HVAC energy use can drop 8-15 %, and preventing moisture-related damage saves on future repair and remediation costs.
