FAQs
Why is a whole-home dehumidifier important for preventing mold growth in Hillsboro?
Hillsboro’s marine-influenced climate brings frequent rain and extended periods of mild, damp weather. When indoor humidity stays above 60 %, moisture condenses on walls, ductwork, and inside the air handler, creating a perfect environment for mold spores to colonize. A whole-home dehumidifier attaches to your HVAC system and automatically pulls moisture out of the air before it circulates through the house, keeping relative humidity in the 40-50 % range that the EPA recommends to inhibit mold growth and protect furnishings, drywall, and electronics.
How does high humidity affect my current heating and air-conditioning equipment?
Excess moisture forces your air conditioner to run longer because it must cool the air and remove water vapor before the thermostat is satisfied. This added runtime increases energy bills, accelerates wear on compressors and blower motors, and can rust coils or drip pans. Humidity also reduces furnace efficiency in winter: damp air feels cooler, so occupants raise the thermostat, burning more fuel. By controlling moisture with a dehumidifier, you reduce the load on both heating and cooling components, extend their service life, and maintain steadier comfort levels.
Can’t I just use portable dehumidifiers instead of a professionally installed unit?
Portable units only treat the single room they are placed in, remove a limited amount of moisture (usually 30–70 pints per day), and require you to empty buckets or connect a drain hose. A whole-home system is hard-ducted into your return plenum, rated for 90–200+ pints per day, automatically drains to a floor sink or condensate pump, and is controlled by a humidistat that works in tandem with your thermostat. The result is consistent humidity control throughout all conditioned spaces, lower noise, and virtually zero daily maintenance.
What size dehumidifier does my Hillsboro home need?
Sizing is based on square footage, typical moisture load, the tightness of the building envelope, and basement or crawl-space conditions. As a rule of thumb, a 2,000–2,500 sq ft home in our climate needs a 90-100 pint-per-day unit, while larger or multi-story homes may require 120–150 pints. During our free in-home assessment we measure indoor humidity, inspect insulation and duct leakage, and use ACCA Manual J calculations to recommend a model that will maintain the desired RH without short-cycling or wasting energy.
How much does professional installation cost, and are there local rebates?
Most whole-home dehumidifier installations in Hillsboro range from $2,200 to $3,800, including equipment, ductwork modifications, a dedicated condensate drain, electrical hookup, and a digital humidistat. Actual cost depends on capacity, whether a fresh-air ventilation feature is added, and the accessibility of your furnace or air-handler. Energy Trust of Oregon currently offers incentives of $150–$250 for ENERGY STAR® certified models, and some utility companies provide low-interest financing or on-bill repayment. We handle all rebate paperwork for you.
What maintenance is required after installation?
Whole-home dehumidifiers are low-maintenance but not maintenance-free. Plan on: • Replacing or cleaning the internal air filter every 6–12 months (more often if you have pets). • Flushing the condensate line annually to prevent algae buildup. • Having our technician inspect the coil, blower wheel, and humidistat calibration during your spring or fall HVAC tune-up. The entire service typically takes under 30 minutes and helps the unit maintain peak efficiency and a 10-15-year life span.
