Review
The ACiQ 2 ton heat pump (SKU ACIQ-24-EHPD-UPG) represents a direct upgrade path for contractors and homeowners maintaining Goodman equipment. As a replacement for the discontinued GSZ140251, this unit preserves installation familiarity while introducing modern R454B refrigerant compliance. The 14 SEER efficiency rating positions it as a practical middle ground, outperforming baseline systems while remaining competitively priced against premium variable-capacity models.
Performance specs tell a practical story. Cooling output reaches 24,000 BTU with heating capability of 34,100 BTU, covering most moderate climate needs. The scroll compressor operates on 208/230/240 volts single phase, requiring a 57 to 60 amp breaker. At 70 dB, expect audible operation during peak cooling. Multi-speed EEM blower motor pushes 1,050 CFM maximum, adequate for 2 ton sizing in properly sealed homes. Energy Star certification confirms the 14 SEER rating meets federal efficiency thresholds without rebate hassles.
Pros & Cons
Pros
- 14 SEER efficiency rating exceeds baseline requirements and qualifies for Energy Star certification
- R454B refrigerant meets modern environmental standards without costly system redesigns
- Dual-function design delivers 24,000 BTU cooling and 34,100 BTU heating from one outdoor unit
- Scroll compressor is proven technology with lower field failure rates than rotary designs
- 10 year warranty with online registration provides solid long-term protection
- Optional electric backup heat up to 10 kilowatts handles extreme cold without fossil fuels
Cons
- Single-stage compressor means less efficient part-load operation compared to variable-capacity competitors
- 70 dB noise level is audible and may concern noise-sensitive residential locations
- 2 ton capacity limits applications to smaller homes or rooms, ruling out whole-house retrofit for larger properties
Who Should Buy
Best For
Contractors replacing GSZ140251 units will appreciate the direct compatibility and familiar Goodman service network. Homeowners in mild to moderate climates with homes under 1,200 square feet will see meaningful savings on heating and cooling bills with the 14 SEER rating.
Consider Alternatives If
Buyers in extremely cold climates should look at higher tonnage models with auxiliary heating, and noise-sensitive properties near bedrooms need units rated below 65 dB.
Installation
Sweat-type connections (3/8 inch liquid line, 3/4 inch suction line) require trained technicians comfortable with brazing. The 45 inch height, 17.5 inch width, and 21 inch depth fit standard outdoor pads. Pre-charged 50 foot linesets simplify job site logistics. Electrical rough-in demands single-phase wiring with appropriate breaker sizing, a straightforward requirement for most residential installations.
Warranty & Reliability
Ten years of parts coverage kicks in after online registration, protecting against defects in compressor, coil, and controls. This covers most field failures contractors encounter. Owner must maintain professional service records and proper refrigerant charge for validity. Registration is mandatory, not automatic, so document the process at commissioning.
