FAQs
Why would a home in Cumberland Gap need a whole-house dehumidifier?
Our region’s humid climate allows excess moisture to build up inside crawl spaces, basements, and living areas. A whole-house dehumidifier tied into your HVAC system removes that moisture before it circulates throughout the home, preventing mold growth, musty odors, wood warping, and higher cooling bills.
How is a dehumidifier installed in an existing heating and air conditioning system?
We mount the dehumidifier unit in your return-air ductwork or a dedicated bypass duct. The installer runs a low-voltage control wire to your thermostat/ humidistat, ties the condensate drain into the home’s plumbing or a sump, and balances the airflow so your existing furnace or air handler continues to deliver proper static pressure. The process typically takes 4–6 hours and does not require major remodeling.
Will a dehumidifier increase my energy usage?
While the dehumidifier itself draws a small amount of electricity, the drier air lets you raise the thermostat by 2–3 °F without sacrificing comfort, reducing A/C runtime. Most customers see a net drop in summer energy costs and less wear on their HVAC equipment.
How do I know what size dehumidifier my house needs?
Sizing is based on square footage, typical indoor humidity levels, foundation type, and the amount of infiltration your home experiences. During a free home evaluation, our technician measures these factors and recommends a unit rated in pints per day. Proper sizing ensures the system runs efficiently without short-cycling.
What maintenance does a whole-house dehumidifier require?
Every 6–12 months, replace or clean the air filter, clear the condensate drain, and inspect the coil for dust buildup. We offer affordable maintenance plans that align dehumidifier service with your routine HVAC tune-ups, so you never have to remember separate schedules.
Is professional installation really necessary, or can I use a portable dehumidifier?
Portable units treat only one room, need to be manually emptied, and can add heat to the space. A professionally installed whole-house dehumidifier integrates with your ductwork, automatically drains, and maintains balanced humidity throughout the entire home. It protects your structure and HVAC system far more effectively and qualifies for manufacturer warranties that require licensed installation.
