Frequently Asked Questions

What Outdoor Packaged air handling unit does Daikin recommend for K-12 schools that need reliable heating in cold climates?2026-09-01T14:02:49+00:00

The Daikin Rebel Applied and Rebel packaged rooftop systems are built for low-rise commercial buildings like schools, with heat pump models rated to operate reliably down to -10°F. They use low-GWP R-32 refrigerant and are designed for year-round heating and cooling without relying on a separate boiler plant.

How energy efficient is the Daikin Rebel rooftop unit for school buildings, and does it help meet sustainability or grant requirements?2026-09-01T14:02:49+00:00

The Rebel rooftop system can achieve part-load efficiencies of up to 22.7 IEER, delivering up to 55% energy savings above ASHRAE 90.1 standards. That level of efficiency is often relevant for schools pursuing energy grants, ESSER-funded upgrades, or state sustainability mandates tied to ASHRAE compliance.

What HVAC equipment improves indoor air quality (IAQ) in classrooms?2026-09-01T14:02:49+00:00

Daikin’s Skyline and Vision air handling units use micro-filtration, UV lights to reduce airborne bacteria, and mold-resistant drain pans and antimicrobial liners to actively combat contamination — features commonly specified in school and healthcare-grade IAQ upgrades. TriState also supplies bipolar ionization (AtmosAir) and dedicated outdoor air systems for facilities prioritizing Energy Savings using the ASHRAE 62.1 IAQ Procedure for calculating the required amount of ventilation air.

Are unit ventilators still a good option for classroom heating and cooling, or should schools upgrade to newer equipment?2026-09-01T14:02:49+00:00

TriState continues to supply Daikin unit ventilators (the historic Herman Nelson/AAF/McQuay product lines), which remain an industry standard for classroom-level heating and cooling. Many schools retrofit these with updated cabinetry and controls rather than replacing the underlying zone-by-zone approach, since it still suits room-by-room classroom control.

Which rooftop unit size is right for a mid-size school building — 3-story office, gymnasium, or library-sized facility?2026-09-01T14:02:49+00:00

The Daikin Maverick II packaged rooftop system (30–50 tons) is specifically positioned for one- to three-story buildings like schools, libraries, and offices, and supports retrofit or new-construction projects. For smaller classroom wings or additions, the Rebel (3–31 tons) is typically the better fit; for larger campuses or applied installations, Rebel Applied scales up to 150 tons.

Does TriState HVAC offer quiet HVAC equipment that meets classroom noise requirements?2026-09-01T14:02:49+00:00

Yes. TriState supplies IAC Acoustics duct silencers for measurable, lab-tested noise reduction, and AcoustiFLO modular plenum fan systems designed specifically for tight mechanical spaces with strict noise limits. Daikin’s Skyline and Vision air handlers are also built as low-sound units, which is relevant for schools where mechanical rooms sit near classrooms, libraries, or auditoriums.
