Humidifiers &
Dehumidifiers.

Ideal indoor humidity sits between 30% and 50%. Too low (common in Utah winters), and you get dry skin, bloody noses, cracked hardwood floors, static shocks, and respiratory irritation. Too high (common in basements and finished lower levels), and you get mold, musty smells, dust mites, wood rot, and condensation on windows. Whole-home humidifiers and dehumidifiers keep indoor humidity in the healthy zone automatically — without the hassle of portable units.

Salt Lake Valley's average winter humidity runs 25% to 35%, but indoor levels often drop below 20% when furnaces are running hard. At those levels, viruses survive longer in the air, respiratory tissue dries out, and wood construction actually contracts enough to create gaps and squeaks. A whole-home humidifier — bypass, fan-powered, or steam — integrates with your HVAC to add moisture to every room automatically.

On the flip side, Utah basements often trap humidity from groundwater, showering, cooking, and laundry. A whole-home dehumidifier or HRV/ERV (heat-recovery or energy-recovery ventilator) pulls excess moisture out while exchanging stale indoor air for fresh filtered outdoor air. HRV/ERV systems are especially valuable for tightly-sealed modern homes where fresh air exchange is the difference between healthy air and stale, stuffy indoor air.

Whole-home humidifiers come in three flavors. Bypass humidifiers are the most common and least expensive — they use your furnace blower to push air across a water panel, evaporating moisture into your supply ducts. Fan-powered humidifiers add their own small fan for better performance and work with systems that don't run the blower continuously. Steam humidifiers generate their own steam electrically, producing the most moisture (best for very large or very dry homes) but costing more to run. We'll recommend the right type based on your home's square footage, blower runtime, and humidity goals.

Whole-home dehumidifiers make the most sense for finished basements, homes with unusually humid summers, or homes where air conditioning alone can't keep humidity below 55%. Unlike portable basement dehumidifiers, whole-home units tie directly into your ductwork, drain automatically, and operate quietly with a humidistat that maintains your setpoint automatically. Capacities range from 70 to 130+ pints per day depending on the size of the space.

HRV and ERV systems are different from humidifiers and dehumidifiers — they're fresh-air ventilators. An HRV (Heat Recovery Ventilator) exchanges stale indoor air for fresh outdoor air while capturing 60 to 80% of the thermal energy from the outgoing air. An ERV (Energy Recovery Ventilator) does the same but also transfers humidity, which is especially valuable in Utah where you want to retain humidity in winter and keep humidity out in summer. Modern tight-sealed homes almost always need HRV/ERV ventilation to maintain healthy indoor air quality — without fresh air exchange, CO2, VOCs, and indoor pollutants build up to levels well above outdoor ambient.
