A whole-home dehumidifier helps reduce excess moisture, which can prevent mold, mildew, and musty odors—especially important during damp seasons in Spokane Valley. It also helps your HVAC system run more efficiently and makes your home feel fresher and more comfortable.
Mainstream starts with an in-home consultation to assess your humidity levels and HVAC system. Then our licensed technicians install the dehumidifier directly into your ductwork, ensuring seamless operation and long-term performance—all backed by our trusted service guarantee.
Yes! Mainstream services and repairs a wide range of whole-home dehumidifier brands. If your system isn’t performing as it should, our technicians can diagnose the issue and get it back up and running—fast and reliably.
Common signs include increased indoor humidity, musty smells, unusual noises, water leaks, or your unit not turning on at all. If you notice any of these issues, call Mainstream for a professional inspection before bigger problems develop.
Humidity is one of those invisible problems that can quietly wreak havoc on your home. From foggy windows and musty odors to mold growth and structural damage, too much moisture in the air can create serious issues for both your health and your property. That’s why Mainstream Electric, Heating, Cooling & Plumbing offers whole home dehumidifier systems—giving homeowners across Spokane and Northern Idaho a smart, long-lasting solution to moisture control.
If your home often feels damp or sticky—or if you’re constantly fighting mildew, allergy symptoms, or warped flooring—it might be time to consider the benefits of a professionally installed whole home dehumidifier.
Excess indoor humidity isn’t just uncomfortable—it’s potentially dangerous. When relative humidity rises above 50%, your home becomes a breeding ground for dust mites, mold, and bacteria. That means more allergy flare-ups, more asthma triggers, and more long-term damage to your walls, floors, and HVAC system.
In the Inland Northwest, we deal with humid summers, tightly sealed winter homes, and moisture-prone basements and crawlspaces. A whole home dehumidifier helps balance indoor humidity all year long by pulling moisture from the air and redistributing it through your existing HVAC system. The result? Cleaner, drier air in every room.
Since 2000, Mainstream has been the trusted name for home comfort across Spokane County and Northern Idaho. We install powerful, energy-efficient dehumidifiers that integrate directly with your current heating and cooling system—delivering whole-home coverage without the noise, maintenance, or space requirements of portable units.
Our licensed technicians take the time to understand your home’s layout, existing ductwork, and moisture patterns to recommend the right system for your needs. Whether you’re upgrading your indoor air quality or solving a persistent humidity issue, we’ll provide honest advice and top-tier service every step of the way.
We’re also available 24/7 for emergency HVAC services, because moisture problems don’t always wait for business hours—and neither do we.
