Costway 36k BTU 3-Ton 19 SEER2 Ducted Central Air Conditioner with Heat Pump

The Costway 3 Ton 19 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 36,000 BTU and AHRI-certified under the 210/240-2024 standard, this 3 ton heat pump system pairs an outdoor condenser (FP11019US) with an indoor air handler (FP11022US) to serve as a direct central HVAC replacement. Installation requires a licensed HVAC professional.

Key specifications

• Cooling & heating capacity — 36,000 BTU (3 tons); rated at 95°F cooling / 47°F heating per AHRI 210/240-2024
• Efficiency ratings — SEER2 19.00 / 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. 217169695

High efficiency replaces aging central AC

A 19 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 — 36,000 BTU capacity suits approximately 1,500–1,800 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., 129.5 lbs.) accommodates both horizontal and vertical mounting; the outdoor unit measures 23 × 28.8 × 28.8 in. and weighs 149 lbs. At 850 CFM airflow, the air handler is sized for the unit's full 3-ton output. Installers should verify existing circuit capacity and line-set sizing before connecting.

Why choose the Costway 3 Ton 19 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, 19 SEER2 cooling efficiency, and one-switch whole-house control, it covers both ends of the comfort calendar in a single ducted installation.
