Review
The ACiQ 2-ton heat pump (model ACIQ-24-EHPD-UPG) occupies practical middle ground in the residential HVAC market. This unit directly replaces Goodman's GSZ140251, making it attractive to contractors managing retrofit projects. The system combines modest capacity with solid efficiency credentials, positioning it as a sensible choice for homeowners seeking dependability over cutting-edge technology.
Performance specs reveal balanced engineering. The unit delivers 24,000 BTU cooling and 34,100 BTU heating, sufficient for moderate-sized homes in mixed climates. Its 14 SEER1 rating and Energy Star certification indicate competent efficiency, though not exceptional by today's standards. The scroll compressor operates single-stage, meaning it cycles on and off rather than modulating power, a design that prioritizes reliability over variable-load optimization.
Pros & Cons
Pros
- 14 SEER1 efficiency meets Energy Star standards with R454B low-GWP refrigerant
- 34,100 BTU heating output provides substantial winter performance for 2-ton systems
- Single-stage scroll compressor design is proven reliable across residential applications
- Multi-speed PSC blower motor adjusts airflow with 1,150 CFM maximum capacity
- 10-year warranty with online registration gives reasonable long-term protection
Cons
- 14 SEER is mid-range efficiency, not competitive with 16+ SEER alternatives available today
- Single-stage compressor runs at full capacity, less efficient than variable-speed models
- 70 dB noise level is moderately loud for residential outdoor installations
Who Should Buy
Best For
Budget-conscious homeowners in transitional climates who need balanced cooling and heating without investing in premium variable-capacity systems. Contractors replacing older Goodman units like the GSZ140251 will appreciate the direct compatibility.
Consider Alternatives If
Buyers in hot climates who prioritize cooling efficiency should explore 16+ SEER models, and those in very cold regions may want higher heating BTU ratings or dual-fuel backup.
Installation
Installation requires standard 208/230/240-volt single-phase power with 57 to 60-amp breaker capacity. The unit weighs 120 pounds and measures 45 inches tall, 17.5 inches wide, and 21 inches deep, fitting typical outdoor pad spaces. Suction and liquid lines use 3/4-inch and 3/8-inch sweat connections respectively, with 50-foot maximum line length and 3/4-inch insulation thickness specified.
Warranty & Reliability
Goodman covers this unit with a full 10-year warranty upon online registration. This protection is industry-standard for mid-tier residential heat pumps. Coverage includes compressor and parts, providing meaningful security against manufacturer defects during typical equipment lifespan.
