FAQs
What does your free moisture assessment include for McMinnville homes?
Our technician will inspect crawl spaces, attics, HVAC equipment, windows, and known trouble spots with thermal-imaging and hygrometer tools. We log indoor relative humidity, temperature differentials, and moisture content in structural wood to determine where excess dampness is entering or accumulating. You receive a written report the same day with photos, findings, and recommended corrective actions—whether that’s sealing air leaks, upgrading ventilation, or installing a whole-home dehumidifier.
Why is controlling indoor humidity so important in the Willamette Valley climate?
McMinnville’s mild, wet winters and warm, muggy summers create a year-round risk of indoor moisture problems. High humidity (above 60 %) encourages mold growth, dust-mite populations, musty odors, wood rot, and premature HVAC corrosion. By keeping relative humidity in the 40-50 % comfort zone, you protect your family ’s respiratory health, preserve furnishings, and improve energy efficiency because your AC doesn’t have to work as hard to remove latent heat.
How does a whole-home dehumidifier integrate with my existing heating and air conditioning system?
We install the dehumidifier in line with your return-air ductwork or as a dedicated ventilating unit, depending on your floor plan. A condensate drain is tied into an existing plumbing line or sump pump, and a smart humidistat is mounted next to your thermostat. The dehumidifier automatically activates when indoor RH rises above your setpoint, removing up to 12 gallons of water per day while sending dry, conditioned air back through your supply vents. It operates independently from the air-conditioning cycle, so you stay comfortable even on mild but humid days.
Will a dehumidifier increase my energy bill?
Standalone room dehumidifiers can add significant kilowatt hours, but a properly sized whole-home unit often lowers overall energy costs. By removing moisture more efficiently than your air conditioner, it lets you raise the thermostat 2–3 °F without sacrificing comfort. Most customers see a 5-10 % reduction in summer cooling costs, and the equipment’s Energy Star-rated compressor consumes about the same power as a standard refrigerator.
How long does installation take, and is there any disruption to my household?
A typical whole-home dehumidifier installation takes 4–6 hours. We schedule at your convenience, lay down protective floor coverings, and clean up every work area before leaving. The only service interruption is turning off the HVAC blower for roughly 30 minutes while we cut into the ductwork. You can remain in the home throughout the process, and we’ll walk you through system operation and maintenance before we leave.
Do you offer financing or rebates for dehumidifier installations in McMinnville?
Yes. We partner with local credit unions to provide zero-interest financing for up to 18 months on approved credit. Customers may also qualify for energy-efficiency rebates from the Energy Trust of Oregon—typically $200–$400—depending on the model’s Integrated Energy Factor (IEF) and your utility provider. We handle all paperwork and apply the rebate as an instant discount on your invoice.
