Humidifier Installation, Service & Repair in Chicagoland

McNally’s installs, services, and repairs Aprilaire whole-home humidifiers for homes throughout the Chicagoland area.

Schedule Your Appointment

Chicago winters are hard on indoor air. When the furnace runs for months at a time, humidity drops, and dry air brings scratchy throats, static shocks, cracked woodwork, and a home that feels colder than the thermostat says. A whole-home humidifier fixes that at the source.

What Is a Whole-Home Humidifier?

Unlike portable room units you have to refill and clean, a whole-home humidifier mounts on your furnace or ductwork and adds moisture to the air your heating system is already circulating. It draws its water supply automatically, works through your existing vents, and keeps your entire house at a comfortable, consistent humidity level all winter.
Proper humidity does more than end dry-air discomfort. It helps protect hardwood floors, trim, and furniture from shrinking and cracking, and air at the right humidity feels warmer, so many homeowners find they can set the thermostat a little lower without feeling it.
And when the seasons flip and the problem is too much moisture instead of too little, its summer counterpart, a whole-home dehumidifier, handles that side of the job.

Why Aprilaire?

McNally’s focuses on Aprilaire humidifiers: the brand that invented the whole-home evaporative humidifier and still builds them in the USA. Aprilaire units are reliable, straightforward to maintain, and parts are easy to get, which matters years down the road when it’s time for a new water panel or a repair.
We install, maintain, and repair the Aprilaire 500, 600, and 700 series, and we’ll help you pick the right model and control setup for your home. We don’t carry the 800-series steam line.

The Aprilaire Models We Install

Every home is different, so we carry the three Aprilaire families that cover nearly every Chicagoland house, each available with manual or automatic control.

Aprilaire 500 Series

The compact bypass humidifier. A great fit for small-to-mid-size homes and tighter mechanical spaces, with the same set-and-forget operation as its bigger siblings.

Aprilaire 600 Series

The large-capacity bypass humidifier and our most common install. More evaporative capacity for mid-to-large homes, in manual (600M) and automatic digital-control variants.

Aprilaire 700 Series

The fan-powered humidifier. Its built-in fan pushes moisture without a bypass duct, delivering the highest output of the line for large homes and homes without room for bypass ducting.

Not sure which fits your home? We’ll size it for you as part of the installation visit.

Humidifier Installation

McNally’s is proud to offer expert installation of both bypass and power humidifier installation. We mount the unit on your furnace or ductwork, tie it into your water supply and controls, and set it up for the way your home actually runs. Call us today for a free installation quote.

Humidifier Maintenance

Humidifiers are simple machines, but they do need a seasonal touch: a fresh water panel each year, a clean orifice and drain, and a control check before the heating season starts. We handle it as a quick standalone visit, or as part of your regular tune-up on the Pot of Gold Maintenance Plan.

Humidifier Repair

Unit not humidifying, leaking, or throwing an error on the control? We diagnose and repair Aprilaire 500, 600, and 700 series units, from solenoid valves and water panels to controls and wiring, and we’ll give you an honest answer if a repair no longer makes sense versus replacing the unit.

Why McNally’s For Your Humidifier?

McNally’s has been keeping Chicagoland homes comfortable since 1999. We’re family-owned, we know what a Midwest heating season does to indoor air, and we install the equipment we’d put in our own homes.
