Cost Guides (Twin Cities)
How much does an indoor air quality system cost?
The short answer
Installed indoor-air-quality equipment in the Twin Cities generally runs about: a whole-home humidifier $400–$1,200; a media air cleaner $600–$1,500; a whole-home dehumidifier $1,500–$3,000+; and a UV lamp $300–$800. Which one (or combination) is right depends on what you're noticing, a free assessment pins it down.
What each system costs, installed
Here's the honest installed range for the most common whole-home IAQ equipment:
- Whole-home humidifier, about $400–$1,200. Adds controlled moisture through your ductwork for Minnesota's bone-dry winters.
- Media air cleaner, about $600–$1,500. A high-MERV whole-home filter that captures far more dust, pollen, and dander than a basic 1-inch filter.
- Whole-home dehumidifier, about $1,500–$3,000+. Clears muggy, clammy summer air and damp basements.
- UV lamp, about $300–$800. Controls mold and bacteria growth on the damp evaporator coil and in the air handler.
These are installed ranges, the exact figure depends on the equipment tier and how it integrates with your system.
What each system does (and who needs it)
Match the equipment to the symptom, not to the biggest package:
- Static shocks, cracked skin, gaps in wood floors? That's dry winter air, a whole-home humidifier. See humidifiers and dehumidifiers in MN.
- Muggy, clammy summers or a damp basement? A whole-home dehumidifier (or a correctly sized AC running longer cycles).
- Dust, allergies, pet dander, pollen? A high-MERV media air cleaner sized to your blower.
- Musty "dirty sock" smell or coil grime? A UV lamp at the coil, see UV light vs. air purifier.
What drives the price up or down?
Within each range, the cost moves with:
- Equipment tier. We install AprilAire whole-home IAQ equipment, and the model and capacity affect the price.
- Integration complexity. Tying into your existing ductwork, drains, and controls is straightforward in some homes and more involved in others.
- Whole-home vs. portable. Whole-home units cost more than a portable tank but treat every room, drain or fill automatically, and run from a humidistat, no refilling.
- Combining systems. A layered setup (filtration plus humidity control, for example) costs more than a single piece but solves more at once.
Financing and getting the right system
The goal is the system that fixes your actual problem, not the most equipment we can sell. A few honest notes:
- Start with the basics. Clean ductwork and the right filter often deliver the biggest, most affordable improvement before you add anything else.
- Financing. For larger or layered IAQ projects, monthly payments keep it manageable, explore financing options.
- Free assessment. We'll tell you whether the fix is humidity, filtration, AC sizing, or ventilation, and whether any current utility rebate applies , so you don't overspend.

Frequently asked questions
- Which indoor air quality system should I get first?
- Start with the problem you actually notice. Dry-air symptoms point to a humidifier, a muggy basement to a dehumidifier, dust and allergies to a media air cleaner, and a musty coil smell to a UV lamp. Often the most affordable first step is clean ducts and a better filter.
- Is a whole-home system worth it over a portable one?
- For treating an entire house, yes. Whole-home units integrate with your HVAC system, condition every room through the ducts, manage water automatically, and run from a humidistat, so you skip the constant refilling and emptying a portable unit needs.
- Do I need all four of these?
- Almost never. Most homes need one or two pieces that target a specific issue. We'll recommend only what solves your problem rather than bundling equipment you won't benefit from.
- What brand of IAQ equipment do you install?
- We install AprilAire whole-home humidifiers, dehumidifiers, media air cleaners, and ventilation, proven equipment that integrates cleanly with your existing system.
