Costway 24k BTU 2-Ton 18 SEER2 Ducted Central Air Conditioner with Heat Pump

The Costway 2 Ton 18 SEER2 Ducted Central Heat Pump System with Air Handler is a matched split system heat pump that delivers whole-home heating and cooling through existing ductwork, using R454B — a low-GWP refrigerant that replaces the outgoing R410A. Rated at 24,000 BTU and AHRI-certified under the 210/240-2024 standard (Ref. No. 217169696), this 2 ton heat pump system pairs an outdoor condenser (FP11018US) with an indoor air handler (FP11021US) to serve as a direct central HVAC replacement. Installation requires a licensed HVAC professional.

Key specifications

• Cooling & heating capacity — 24,000 BTU (2 tons); rated at 95°F cooling / 47°F heating per AHRI 210/240-2024
• Efficiency ratings — SEER2 18.00 / HSPF2 9.00 (Region IV) / EER2 10.00
• Operating temperature range — 5°F–122°F (-15°C–50°C) with built-in auto defrost
• Refrigerant — R454B (low-GWP; regulatory-compliant replacement for R410A)
• Certifications — ETL listed; AHRI certified, Ref. No. 217169696

High efficiency replaces aging central AC

An 18 SEER2 rating puts this system well above the federal minimum for most U.S. climate regions, reducing cooling energy costs compared to older central systems. The HSPF2 of 9.00 supports cost-effective electric heat down to 5°F, covering most residential heating seasons without a backup furnace. For homeowners with existing ductwork, this is a straightforward upgrade that preserves the whole-house coverage of a central system without the complexity of a multi-zone ductless installation.

Key Applications

• Central AC replacement — designed to drop in where a forced-air system already serves the house, reusing existing ducts and line-set routing.
• Large residential spaces — 24,000 BTU capacity suits approximately 1,000–1,200 sq. ft., depending on local climate and insulation levels.
• Basements and attics — the air handler installs horizontally or vertically, making it practical in low-clearance mechanical rooms or tight attic installations.
• Cold-climate homes — reliable operation down to 5°F with auto defrost eliminates the need for supplemental heat in moderate winter climates.
• Light commercial spaces — 208/230V compatibility and ETL listing support small commercial applications alongside residential use.

Flexible installation and control options

• Dual communication modes — supports RS485 or standard 24V thermostat wiring for compatibility with most smart home platforms and programmable thermostats.
• 6 operating modes — Auto, Cool, Dry, Fan, Heat, and Emergency Heat.
• 8 fan speeds — Mute through Turbo (plus Auto), with low-noise settings for occupied rooms.
• Timer scheduling — 12-hour, 24-hour, or weekly schedules via the included wall thermostat and 49 ft. thermostat wire.

Works with existing ductwork and wiring

The system runs on 208/230V single-phase, 60Hz power, matching standard residential and light commercial service. Refrigerant line connections use copper pipe: 3/8 in. liquid and 3/4 in. gas, with four connectors included. The package also includes 49 ft. of connection wire. The indoor air handler (45.5 × 21 × 21 in., 128 lbs.) accommodates both horizontal and vertical mounting; the outdoor unit measures 23 × 28.8 × 28.8 in. and weighs 134 lbs. At 850 CFM airflow, the air handler is sized for the unit's full 2-ton output. Installers should verify existing circuit capacity and line-set sizing before connecting.

Why choose the Costway 2 Ton 18 SEER2 Ducted Central Heat Pump System?

Unlike mixing unmatched components, this system ships as an AHRI-certified pair — the efficiency ratings are guaranteed for this specific indoor/outdoor combination, not estimated. The switch to R454B refrigerant protects the investment against R410A phase-out timelines, avoiding a forced retrofit down the road. With cold-weather operation to 5°F, 18 SEER2 cooling efficiency, and one-switch whole-house control, it covers both ends of the comfort calendar in a single ducted installation.
