Accessories

This category covers the add-ons that keep systems running safely and efficiently: Curbs & Adapter Curbs for rooftop placements, 3 Phase Heat Strips for electric heat, 3 Phase Service Parts, and Equipment Accessories including condensate safety devices and fittings. Ideal for licensed contractors, property managers, and DIY-capable owners who plan pro installation, most items are priced from $1 to $245.

Use this section to add or replace electric heat in 3-phase air handlers, set units on code-compliant curbs, and maintain drain safety with float switches and pans. Electric heat kits are offered in common kW sizes-5kW, 8kW, 10kW, 15kW, 18kW, 20kW, 30kW, 40kW, 45kW, and 60kW-so you can match capacity and electrical limits. Rooftop curbs and adapter curbs simplify changeouts when the new unit footprint differs from the existing curb.

Specs note: SEER2 and HSPF2 do not apply to most accessories; BTU or tonnage matters only when matching to the connected air handler or rooftop unit. Refrigerant details are generally equipment-driven, so choose service parts that align with your system’s refrigerant and controls. Always verify ampacity, breaker size, and maximum allowable heat per the air handler nameplate-professional installation is required for 3-phase work.

Frequently Asked Questions

  • How do I choose the correct kW rating for a 3-phase heat strip?

    Match the air handler’s maximum electric heat rating, available ampacity, and required airflow. Select from 5kW-60kW options to meet the load and code requirements.

  • Are curbs and adapter curbs compatible with my rooftop unit brand?

    Yes-use model-specific curbs or adapter curbs. Have both the existing curb dimensions and the new unit model number to confirm a proper fit.

  • What accessories are required when adding electric heat to a Daikin air handler?

    Typically a matched heat kit, appropriate breakers or fuses, wiring harnesses, and a field disconnect. Follow the unit’s documentation for approved kits and wiring.

  • Do 3-phase service parts in this category fit both new and legacy models?

    Many parts are model-specific. Verify part numbers, serial ranges, and control compatibility before ordering.

  • Can I install a heat strip myself or is a licensed electrician required?

    Professional installation is required. 3-phase electric heat involves permits, code compliance, and equipment warranty considerations.

  • How do I size and select a curb or adapter curb for replacement units?

    Measure roof opening, duct sizes, supply/return orientation, and unit footprint/weight. Use an adapter curb when the new unit’s base does not match the existing curb.

  • Which brands of accessories are available for Daikin systems?

    We offer Daikin-compatible OEM heat kits and accessories, plus complementary parts from Goodman, Aquaguard, Parker, and others where appropriate.

  • What safety devices are recommended for condensate overflow in accessory installs?

    Use float or pan switches, secondary drain pans, proper traps, and cleanout fittings to shut down equipment and prevent water damage.

  • Are these accessories suitable for light commercial applications?

    Yes. They’re selected for 3-phase and light commercial service; confirm electrical ratings and mechanical fit for each job.

  • What is the typical price range and lead time?

    Most accessories run about $1-$245. Stocked items ship quickly; custom or made-to-order curbs may require additional lead time.
