Review
The ACiQ 4-ton combination system delivers heating and cooling in a proven Goodman-based package. This 5-ton condenser paired with 120,000 BTU furnace represents practical engineering for contractors and homeowners replacing standard equipment. The horizontal A-coil configuration fits common attic and basement installations. At $3,136, this system sits in the accessible mid-range where reliability and decent efficiency matter more than premium features.
Heating efficiency reaches 96% AFUE with a two-stage natural gas or propane burner that modulates output based on demand. Cooling delivers 48,000 BTU at 13 SEER1 using R454B refrigerant, enough for moderate climates and medium-sized homes. The variable-speed ECM blower motor adjusts airflow up to 2,000 CFM, reducing runtime waste. These specifications represent solid middle-ground performance, not leading-edge, but appropriate for replacement cycles and budgets under $3,500.
Pros & Cons
Pros
- 96% AFUE heating efficiency reduces fuel costs compared to 80-90% units, especially in heating-heavy regions
- 13 SEER1 rating with R454B refrigerant meets current efficiency standards and qualifies for Energy Star certification
- Two-stage burner and variable-speed ECM blower motor optimize performance across different load conditions
- 120,000 BTU heating output handles mid-size homes effectively, paired with 48,000 BTU cooling capacity
- 10-year warranty with online registration provides solid coverage without excessive complexity
- Reciprocating compressor design is field-serviceable and proven reliable for contractor maintenance
Cons
- Single-stage cooling means less granular temperature control and higher runtime in mild weather compared to two-stage units
- 76 dB noise level is louder than premium inverter-driven systems, noticeable during operation
- SEER1 of 13 is mid-range, not top-tier, so energy bill savings won't match 16+ SEER units over system lifetime
Who Should Buy
Best For
Contractors replacing failed Goodman units in customer homes, or homeowners with 2,000-3,000 square foot homes in moderate climates seeking reliable heating and cooling without premium pricing. This system excels for those replacing 10-15 year old equipment where efficiency gains matter more than cutting-edge performance.
Consider Alternatives If
Homeowners in very hot or very cold climates needing maximum efficiency, or those prioritizing silent operation should look at higher SEER/AFUE tier systems or variable-capacity models.
Installation
This horizontal unit requires 115V single-phase 60Hz power with breaker sizing between 26.3 and 45 amps, straightforward for standard residential panels. The sweat valve connections use 3/8-inch liquid and 1 1/8-inch suction lines, standard for field installation. Plastic PVC exhaust flue compatibility simplifies venting. Overall installation complexity is moderate, typical for HVAC contractors, with no unusual ductwork or electrical demands.
Warranty & Reliability
ACiQ backs this system with 10 years parts coverage upon online registration, a solid middle-tier warranty. Registration takes minutes and documents proof of purchase. Coverage excludes wear items and improper installation. This warranty length is typical for mid-range systems, offering reasonable protection without the extended terms seen on premium equipment.
