Costway 24k-36k BTU 2-3-Ton 18.6-20 SEER2 Ducted Central Air Conditioner with Heat Pump

The Costway 2–3 Ton 18.6–20 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 2–3 tons and AHRI-certified under the 210/240-2024 standard (Ref. No. 217221416), this system pairs an outdoor condenser (FP10982US) with an indoor air handler (FP10985US) to serve as a direct central HVAC replacement. Installation requires a licensed HVAC professional.

High efficiency replaces aging central AC

An 18.6–20 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 9.0–9.4 supports cost-effective electric heat down to -4°F, covering most residential heating seasons without a backup furnace. Inverter technology continuously adjusts compressor speed to maintain desired comfort levels while minimizing energy use. 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 — 2–3 ton capacity suits approximately 1,000–1,500 sq. ft., depending on local climate and insulation levels.
• Basements and attics — the multi-position 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 -4°F with auto defrost eliminates the need for supplemental heat in moderate to cold 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.
• Inverter-driven compressor — modulates output for precise temperature control and lower operating costs versus single-stage systems.
• Auto defrost — built-in defrost cycle ensures reliable outdoor unit performance in extreme cold weather.
• Quiet operation — 49 dB indoor noise level won't disrupt daily activities or sleep.

Works with existing ductwork and wiring

The system runs on 208/230V single-phase, 60Hz power, matching standard residential and light commercial service. The outdoor unit fan motor is rated at 208/230V~60Hz, 1 Phase, 1.8A, 1/4HP, with a minimum circuit amperage of 20A. The indoor unit fan motor is rated at 208/230V~60Hz, 1 Phase, 3.8A, 1/2HP, with a minimum circuit amperage of 5A. The indoor air handler (45.8 × 22.1 × 19.7 in. H×L×W, 131 lbs.) accommodates both horizontal and vertical mounting; the outdoor unit measures 29.5 × 29.5 × 25 in. and weighs 141 lbs. Installers should verify existing circuit capacity and line-set sizing before connecting.

Why choose the Costway 2–3 Ton 18.6–20 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 -4°F, up to 20 SEER2 cooling efficiency, inverter-driven precision, and one-switch whole-house control, it covers both ends of the comfort calendar in a single ducted installation. Energy Star, ETL, and AHRI certifications confirm it meets the highest standards for efficiency, safety, and performance.
