FAQs

Why is a whole-house dehumidifier important in Decatur’s climate?

Decatur experiences long, hot, and humid summers, and moisture levels frequently exceed 60 % RH indoors. High humidity makes rooms feel warmer, forces your air conditioner to run longer, encourages mold growth, and can warp wood floors or furniture. A whole-house dehumidifier automatically removes excess moisture across every room, keeping indoor relative humidity in the ideal 40–50 % range, which improves comfort, protects your home’s structure, and helps your AC cool more efficiently.

How is a whole-house dehumidifier installed in my existing HVAC system?

Our technicians mount the dehumidifier in a mechanical room, attic, or crawl space and connect it to your supply and/or return ductwork so the unit treats all the air handled by your HVAC system. A dedicated condensate drain line carries the collected water to a floor drain or condensate pump. The installer also adds a 120 V or 240 V electrical circuit (depending on model) and an integrated or stand-alone humidistat so you can set your desired humidity level. The process normally takes 4–6 hours and leaves no visible equipment inside your living areas.

What size dehumidifier do I need for my Decatur home?

Capacity is measured in pints of water removed per day and is based on square footage, ceiling height, typical indoor moisture load, and infiltration rates. Most Decatur homes require units rated 70–120 pints/day, but larger houses or those with basement moisture issues may need 130–200 pints/day. During an on-site assessment we perform a Manual J load calculation, inspect ductwork, and use hygrometers to determine actual conditions before recommending the correctly sized model so you avoid under- or over-sizing.

Will a whole-house dehumidifier raise my energy bills?

A dehumidifier does consume electricity (generally 3–7 amps), but it often lowers overall energy costs because drier air feels cooler, allowing you to set your thermostat 2–3 °F higher without sacrificing comfort. Reduced run time for your air conditioner and prevention of mold-related repairs also offset operating costs. ENERGY STAR® rated models we install remove up to 30 % more moisture per kilowatt-hour than standard units, making them an efficient upgrade for Decatur homeowners.

What routine maintenance does a whole-house dehumidifier require?

Compared with portable units, whole-house systems need minimal upkeep. Every 3–6 months you should replace or clean the air filter to maintain airflow. Twice a year inspect and flush the condensate drain to prevent clogs and algae growth. During your annual HVAC tune-up, our technician will check refrigerant pressures, clean the evaporator coil, verify humidistat calibration, and ensure duct connections remain airtight. Following this schedule keeps your unit running reliably for 10–15 years.

How much does professional installation cost in Decatur and what factors affect the price?

Total project cost typically ranges from $2,200 to $3,800, including equipment, labor, electrical work, and a new humidistat. Pricing varies based on unit capacity, ENERGY STAR® or high-performance models, the need for additional return or supply ducts, crawl-space versus attic placement, and whether a condensate pump must be added.
