Costway 48k-60k BTU 4-5-Ton 17-17.5 SEER2 Ducted Central Air Conditioner with Heat Pump

The Costway 4–5 Ton 17–17.5 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. AHRI-certified under the 210/240-2024 standard (Ref. No. 217221417), this system pairs an outdoor condenser (FP10983US) with an indoor air handler (FP10986US) to serve as a direct central HVAC replacement for larger homes and light commercial spaces. Installation requires a licensed HVAC professional.

High efficiency replaces aging central AC

A 17–17.5 SEER2 rating puts this system above the federal minimum for most U.S. climate regions, reducing cooling energy costs compared to older central systems. The HSPF2 of 8.6–9.0 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 and building operators 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 — 4–5 ton capacity suits approximately 2,000–2,500 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.
• Overload protection — built-in safeguards protect the system from electrical overload, extending equipment lifespan.
• Quiet operation — 55 dB indoor noise level keeps disruption to a minimum during daily activities.

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 30A. The indoor unit fan motor is rated at 208/230V~60Hz, 1 Phase, 5.4A, 3/4HP, with a minimum circuit amperage of 7A. The indoor air handler (53.2 × 24.5 × 22.1 in. H×L×W, 171.5 lbs.) accommodates both horizontal and vertical mounting; the outdoor unit measures 29.5 × 29.5 × 32.9 in. and weighs 192 lbs. Installers should verify existing circuit capacity and line-set sizing before connecting.

Package includes

• 1 x Outdoor Unit (FP10983US)
• 1 x Indoor Unit (FP10986US)
• 1 x Screw Kit

Why choose the Costway 4–5 Ton 17–17.5 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 17.5 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.
