FAQs
What is a whole-home dehumidifier and how does it work with my heating and air-conditioning system?
A whole-home dehumidifier is a permanently installed appliance that pulls excess moisture from all the air circulated by your HVAC system. It is typically ducted into your existing supply and/or return ductwork, where a dedicated fan draws humid air across a cold evaporator coil. Moisture condenses on the coil and is drained away, while the dried air is reheated slightly and sent back through the ducts. Because the unit ties directly into your HVAC controls, it can run independently of heating or cooling to maintain your set humidity level year-round.
Why is dehumidification so important in Reliance?
Reliance experiences long stretches of warm, humid weather that can push indoor relative humidity above the recommended 30â50 %. High humidity promotes mold, dust-mite growth, wood warping, and that sticky, uncomfortable feeling even when the thermostat reads a comfortable temperature. By removing moisture, a whole-home dehumidifier protects your homeâs structure and finishes, improves indoor air quality, and allows you to set the thermostat a few degrees higher without sacrificing comfort, reducing cooling costs in our humid climate.
Can a whole-home dehumidifier be added to my existing HVAC system, or do I need new equipment?
In most cases, we can integrate a dehumidifier with your current forced-air furnace or heat-pump system. Our technicians install a dedicated return or supply bypass duct, wire the unit to your air handler, and connect it to a digital humidistat or your smart thermostat. You only need new equipment if your system lacks sufficient airflow or if the ductwork is inaccessible. During your free in-home assessment, we measure static pressure, airflow, and moisture load to size the dehumidifier correctly and confirm compatibility.
What is involved in the installation, and how long does it take?
A standard installation includes mounting the dehumidifier near your air handler (often in the basement, mechanical closet, or attic), cutting and connecting 6â8 in. insulated bypass ducts, adding a condensate drain to the nearest plumbing line or condensate pump, wiring the power supply, and integrating the control wiring with your thermostat or a dedicated humidistat. Most projects take 4â6 hours and are completed in a single visit. We test for leaks, calibrate the humidistat, and show you how to adjust settings before we leave.
How much maintenance does a whole-home dehumidifier require?
Routine upkeep is simple: replace or clean the unitâs air filter every 6â12 months (or as indicated by the filter monitor), keep the condensate drain line clear, and have the coil and fan inspected annually during your HVAC tune-up. Unlike portable units, youâll never have to empty water bucketsâthe system drains automatically. With proper maintenance, most whole-home dehumidifiers last 10â15 years.
Will a dehumidifier increase my energy usage, and can it help lower cooling costs?
A whole-home dehumidifier uses electricityâtypically 3â6 kWh per day during peak summer monthsâbut it can reduce your overall energy bill. By keeping humidity in check, you can raise the thermostat 2â3 °F and still feel comfortable, cutting air-conditioner runtime by up to 15 %. Lower humidity also helps your HVAC system run more efficiently by preventing evaporator-coil moisture overload. Many homeowners see a net energy savings, especially in Relianceâs humid climate.
