Plainfield Plumber for Whole-Home Humidity
Leto Plumbing & Heating, Inc. installs and repairs whole-home humidifiers in Plainfield and across Will County. When your furnace runs around the clock from November through February, it strips moisture from every room. Dry skin, cracked lips, nosebleeds and worse asthma are what happens when humidity drops below 35% and stays there. We've fixed that for local homeowners for 24 years, with a 4.8-star rating across 53 Google reviews. Call (815) 609-3150.
A whole-home unit ties into your furnace's ductwork and water supply, and it has to be matched to your existing heating system. Our background-checked technicians know when you need a bypass unit and when you need a fan-powered one. Financing is available.

Humidifier Services We Provide in Plainfield
New Humidifier Installation
We size the unit to your furnace, ductwork and square footage, and handle the water line, humidistat wiring and duct connection in one visit.
Humidifier Repair
No moisture, leaking, or a humidistat that won't hold? Common repairs (solenoid valves, water panels, distribution trays) are done the same visit. An improperly seated connection can leak behind the unit for months, so we check every one.
Annual Maintenance
Mineral scale builds up with Will County water. We clean, inspect and replace the water panel at the start of heating season, ideally alongside heating system maintenance.
Humidistat Replacement
A bad humidistat under- or over-humidifies. We replace and calibrate it, and install smart thermostats with humidity control.

Kathy WendellWritten on behalf of my mom Annie: I am very satisfied with Chris Leto's service. He addressed the issue quickly and professionally. Charged a fair price.
Alvin KIn February of 2026 I used Leto Plumbing & Heating on two occasions. First for an emergency after hours weekend call when my sump pump line was frozen during our recent sub-zero weather. The second was a routine maintenance call to flush my hot water heaters. Both times the individuals that came out were pros who were friendly, knowledgeable and got the job done right the first time. Would highly recommend!
