What makes a difference

Define the application before selecting equipment

01

Installation windows

Identify holidays, summer work periods and occupied-building restrictions. Request current lead times rather than assuming equipment will arrive within a particular break.

02

Existing-system capacity

Review fan capability, coil duty and available space before adding filtration or replacing components.

03

Room use and noise

Classrooms, labs, shops and kitchens need different solutions. Portable equipment selection should include acoustics, placement and service access.

04

Long-term maintenance

Plan filter and lamp replacement, cleaning access and spare components. IAQ equipment supplements an appropriate ventilation and building-maintenance plan.

Project questions, answered

Can we replace a coil without replacing the whole air handler?

Often a coil-only replacement can be evaluated. Provide drawings, dimensions, condition information and operating requirements so the replacement scope can be reviewed.

Can you guarantee equipment for summer installation?

We can request current factory lead times and review the project schedule. Availability and delivery commitments must be confirmed for the selected equipment.

Will a portable air cleaner replace outside-air ventilation?

No. Supplemental particulate cleaning and outside-air ventilation serve different functions. Review both as part of the campus HVAC plan.
