THE EQUIPMENT GUIDE / Ventilation & indoor air

Whole-home humidifiers

Add moisture with the building envelope in mind.

A whole-home humidifier adds moisture to an air system. The appropriate control strategy depends on the building and outdoor conditions, not simply a preferred indoor setting.

PLANNING / SELECTION / HANDOVER

Before choosing the equipment

Describe dry-air concerns and any existing window condensation. Ask which humidifier type fits the equipment and how water quality, drainage and maintenance affect the choice.

What belongs in the quote

The proposal should include water connections and control integration. Ask for operating guidance that addresses changing weather and signs that the moisture setting needs review.

Think about the surrounding system

Describe the actual concern: moisture, stale rooms, particles, odours or an exhaust requirement. These are different problems. Ask the designer to explain what the proposed equipment addresses, what remains outside its scope and how the result will be measured. Include filter access and regular maintenance in the plan.

Three questions for your contractor

  1. Which humidifier type fits this system?
  2. How will condensation risk be considered?
  3. What cleaning and water-related upkeep is required?

Prepare a useful first conversation

Bring the site location, building use, equipment model details and photographs of accessible equipment. Describe the problem or planned change and any access or shutdown constraints. Ask the contractor to identify design assumptions, excluded work, required approvals and who will commission the finished system.

This is a project-planning guide. Final equipment selection and installation details need a qualified contractor or designer familiar with the site.
