FAQs
Why is a whole-home dehumidifier important for controlling mold and mildew in Duff’s humid climate?
Duff experiences long stretches of warm, humid weather in which indoor relative humidity (RH) can easily climb above 60 percent—the threshold at which mold spores start to germinate. A whole-home dehumidifier, installed in the HVAC ductwork, continuously removes excess moisture from every room, keeping RH in the ideal 40–50 percent range. By depriving mold and mildew of the moisture they need, the unit protects drywall, wood framing, and furnishings, while also improving indoor air quality and comfort.
How do I know if the moldy smell in my home is coming from my HVAC system?
Musty odors that intensify when the heat or air conditioning cycles on are a strong clue that mold or mildew is growing inside the air handler, drain pan, or ducts. Other indicators include visible black or white growth on supply registers, condensation on ducts or around the indoor coil, and occupants experiencing respiratory irritation only while indoors. Our technicians can confirm the source by performing a moisture inspection, duct camera scan, and air-sampling test to pinpoint contaminated areas before recommending dehumidification and remediation.
What is involved in a professional dehumidifier installation?
1) Load calculation: We measure the home’s square footage, average moisture load, and HVAC airflow to select a properly sized unit. 2) Placement: The dehumidifier is mounted in the mechanical room, crawl space, or attic and tied into the return plenum so dry air is distributed through existing ducts. 3) Drainage: A dedicated PVC drain line or condensate pump is installed to route water safely to a floor drain or exterior. 4) Controls: A wall-mounted or integrated humidistat is wired to the furnace/air-handler control board. 5) Commissioning: We verify airflow, check for leaks, calibrate the humidistat, and demonstrate operation and maintenance to the homeowner. Most projects take 4–6 hours and require no drywall repair.
Will installing a dehumidifier increase my energy bill?
A whole-home dehumidifier does consume electricity (typically 3–8 amps, 115 V), but it often lowers overall energy costs because the air conditioner no longer has to over-cool the house to wring out moisture. By keeping RH in check, the thermostat can be set 2–3 °F higher without sacrificing comfort, and the AC compressor runs less. Homeowners in Duff commonly see summer energy savings of 5–15 percent, while also avoiding the expense of mold remediation and structural repairs.
How often does the dehumidifier need maintenance and filter changes?
Replace or clean the dehumidifier’s air filter every six months, or more frequently if you have pets or recent construction dust. The condensate drain line should be flushed with a mild vinegar solution annually to prevent clogs, and the evaporator coil should be inspected for dirt or biofilm buildup at the same time. During our annual maintenance visit we also test the humidistat, verify refrigerant pressures, and sanitize the cabinet, ensuring optimum performance and mold prevention.
Can a dehumidifier be integrated with my existing heating and air conditioning equipment, or do I need a new system?
In most Duff homes a whole-home dehumidifier can be retrofitted to your current furnace or air-handler. We tap into the supply and return plenums so the unit shares ductwork with the HVAC system, and we coordinate controls so heating, cooling, and dehumidification work together instead of competing. Only if your existing equipment is significantly undersized, has major duct leaks, or is nearing the end of its life would we advise upgrading the HVAC system at the same time. Otherwise, integration is straightforward, cost-effective, and minimally disruptive.
