Daikin AMST Series Air Handler & Coil

Key Features & Benefits

Below are the main highlights of the Daikin AMST Series, incorporating helpful SEO/LSI terms such as “multi-position air handler,” “ECM blower motor,” “internal TXV,” and “all-aluminum evaporator coil.”

• 9-Speed ECM Blower Motor
  The AMST comes equipped with a 9-speed ECM, direct-drive blower motor that allows precise airflow control. This results in quieter performance, improved comfort, and better overall energy efficiency.

• Factory-Installed Internal TXV
  The built-in thermal expansion valve ensures accurate refrigerant metering. It supports both AC and heat pump applications, making it compatible with properly matched Daikin outdoor units.

• All-Aluminum Evaporator Coil & Low-Leakage Cabinet
  The coil uses an aluminum tube-and-fin design for corrosion resistance and long-term durability. The cabinet is tested for low air leakage (under 2.0% at 1.0″ H₂O and under 1.4% at 0.5″ H₂O) to enhance overall system performance.

• Multi-Position Configuration
  Whether your installation requires horizontal, vertical, up-flow or down-flow mounting, the AMST adapts easily. This flexibility makes it ideal for attics, closets, basements, and tight mechanical rooms in many Mississauga homes.

• Wide Capacity Range & Optional Electric Heat Kits
  Available from 1½ to 5 tons with optional electric heat kits (3 kW to 25 kW), the AMST provides a wide selection of configurations to meet different home comfort needs.

• SmartFrame™ Cabinet & Service-Friendly Design
  The cabinet features SmartFrame™ technology, foil-faced insulation, tool-less filter access, and condensation-reducing construction that simplifies servicing and enhances reliability.

Warranty & Registration

• The AMST Series includes a 12-Year Parts Limited Warranty when the unit is installed by a certified professional, registered within 60 days, and maintained annually as recommended.

• Warranty eligibility depends on correct equipment matching, proper installation, and ongoing maintenance.
