Tired of waking up with a dry, sore throat or irritated sinuses during the Chicago winter? While freezing outdoor temperatures are tough, the bone-dry air inside your home can be just as damaging to your health and comfort. Low indoor humidity strips moisture from your skin and respiratory passages, causes static shock, and can even shrink and crack your hardwood floors and wood furniture.
Watch our quick video guide to see why dry indoor air happens and how a whole-home humidifier restores balanced comfort across your entire living space:
At Deljo Heating, Cooling & Plumbing, we provide complete whole-house humidifier services, ensuring your family stays healthy and your home stays protected. Whether you need a brand-new installation or a repair on an existing unit, our team is available 24/7 for live call intake and priority service dispatch.
Why Install a Whole House System?
A central humidifier installation does more than a small, portable unit. Instead of just adding moisture to one room, a whole-home system integrates with your HVAC ductwork to distribute moisture evenly to every corner of your house.
By balancing humidity levels, you will:
- Feel more comfortable at lower temperatures (saving energy).
- Sleep better by relieving a dry throat and nasal passages.
- Protect your home, including hardwood floors, musical instruments, and antique furniture.
Professional Whole House Humidifier Installation
Stop filling portable tanks every day. Our whole-house humidifier installers can find the perfect solution for your specific heating system. We install and service the three primary types of whole-home systems:
- Steam Humidifiers: The most efficient option, boiling water to create steam independent of your furnace cycle. Ideally suited for larger homes or those requiring precise humidity control.
- Bypass Humidifiers: A reliable, energy-efficient choice that uses your furnace’s own airflow to pass air through a water panel.
- Fan-Powered Humidifiers: Perfect for tight spaces where bypass installation isn’t feasible, using an internal fan to push moisture directly into the supply duct.
Our Installation Process
We don’t just plug it in and leave. When you choose Deljo for your whole house humidifier installation or whole home humidifier installation:
- We Measure: We calculate your home’s square footage and insulation factors to size the unit correctly.
- We Connect: We professionally plumb the unit into your water line and wire it to your furnace controls.
- We Test: We verify the humidistat is reading accurately and the drainage is flowing freely.
- We Educate: We show you how to adjust settings for different outdoor temperatures.
Fast Whole House Humidifier Repair
Is your humidifier leaking, making strange noises, or failing to keep humidity levels up? A broken humidifier can lead to water damage in your basement or a return to uncomfortable dry air.
Our team has 100+ years of experience in Chicago, meaning we have seen (and fixed) every make and model. We offer 24/7 emergency service for whole house humidifier repair, addressing common issues such as:
- Clogged water panels or mineral buildup.
- Leaking water lines or backed-up drain lines.
- Faulty solenoids (the valve that lets water in).
- Humidistat control failures.
Whole Home Humidifier Maintenance
Because these systems rely on water, they are prone to mineral scale and mold if neglected. To keep your system hygienic and efficient, whole house humidifier maintenance (or whole home humidifier maintenance) is required at least once a year—typically right before winter begins.
What Does a Maintenance Visit Include? While basic upkeep is easy, we take it a step further to ensure longevity:
- Replacing the Water Panel: The evaporator pad creates the humidity; if it’s clogged with calcium, the unit stops working.
- Clearing the Drain Line: We ensure water isn’t backing up into your furnace.
- Cleaning the Distribution Tray: Ensuring water flows evenly across the pad.
- System Check: Verifying the humidistat turns the water on and off correctly.
