FAQs
What causes musty odors in my Collegedale home and how can a whole-home dehumidifier help?
Musty odors are usually created when indoor humidity stays above 60%, allowing mold, mildew, and bacteria to thrive in ductwork, crawl spaces, and other dark areas. A whole-home dehumidifier draws moist air across a cold coil, condenses and drains the water, then sends the drier air back through your HVAC system. By keeping relative humidity in the 40–50% range, it stops microbial growth at the source and removes the stale, musty smell that goes with it.
How does a dehumidifier integrate with my existing HVAC system?
We install the dehumidifier in line with your return or supply ductwork—or as a dedicated bypass loop—so it treats all the air that circulates through your heating and cooling equipment. A built-in or wall-mounted humidistat communicates with the HVAC thermostat to make sure only one system runs at a time, preventing short-cycling and maximizing efficiency. The unit has its own condensate drain or pump, so you don’t have to empty a bucket.
What size dehumidifier do I need for my home in Collegedale?
Sizing is based on square footage, typical moisture load, crawl-space or basement conditions, and family lifestyle. In most Collegedale homes, units rated between 70 and 120 pints per day do the job. During a free in-home assessment, we measure the space, inspect ductwork and insulation, and use ACCA Manual P guidelines to recommend the right capacity so the system isn’t undersized (ineffective) or oversized (short-cycles and wastes energy).
How soon will I notice an improvement in air quality after installation?
Most homeowners report a noticeable drop in odor and stickiness within 24–48 hours. Because the dehumidifier runs continuously until it reaches the target setpoint, moisture levels fall quickly, and your HVAC filter traps the now-dry mold spores and dust. Within the first week you should also feel cooler at a higher thermostat setting, often allowing you to raise the temperature 2–3°F without losing comfort.
Will a dehumidifier increase my energy bills?
While the dehumidifier uses electricity, it lets you run your air conditioner less. Drier air feels cooler, so many customers raise the thermostat and cut AC runtime by 10–15%. The unit itself is energy-efficient (most draw 4–7 amps) and only cycles when humidity is high. Net annual operating cost in the Collegedale climate typically ranges from $4–$10 per month, and many households see a slight overall drop in energy costs.
What maintenance is required to keep my dehumidifier and HVAC system running efficiently?
Maintenance is straightforward: replace or wash the dehumidifier’s air filter every 3–6 months, inspect and clear the condensate drain line seasonally, and have our technicians clean the internal coil once a year. During your spring or fall HVAC tune-up, we also verify refrigerant pressures, calibrate the humidistat, and check duct connections. With these simple steps, most units last 10–15 years and stay covered under the manufacturer’s warranty.
