Review
ACiQ's 4 ton combo system pairs a 96% AFUE furnace with a 13 SEER1 air conditioner in a downflow-compatible cabinet. This is an Energy Star qualified unit that targets the mainstream replacement market, balancing solid efficiency ratings with accessible pricing. The system handles 100,000 BTU heating and 48,000 BTU cooling, making it sized correctly for average single-family homes in moderate climates.
Heating performance leverages a two-stage burner that adjusts output based on demand, maximizing fuel economy. The variable-speed ECM blower motor ramps from minimal to 2000 CFM, matching airflow to actual heating or cooling needs rather than running at constant speed. At 13 SEER1 with R454B refrigerant, cooling efficiency meets current standards. The single-stage compressor is straightforward and durable, though it lacks the modulation of pricier inverter models.
Pros & Cons
Pros
- 96% AFUE heating efficiency with two-stage burners reduces winter gas bills measurably
- 13 SEER1 cooling rating hits Energy Star certification, qualifying for utility rebates
- Variable-speed ECM blower motor adapts airflow from 0 to 2000 CFM for comfort and efficiency
- R454B refrigerant meets modern environmental standards with lower GWP than legacy options
- 10-year warranty with online registration provides solid long-term protection for major components
Cons
- 13 SEER1 is solid but not best-in-class compared to 14-16 SEER1 premium units
- Single-stage compressor means cooling cycles on/off rather than modulating capacity smoothly
- 76 dBA noise level runs audible, especially during cooling operation in quiet neighborhoods
Who Should Buy
Best For
Contractors and homeowners replacing aging furnace-AC combos who need reliable performance in downflow configurations. Good fit for those chasing rebates, building budgets, and wanting trustworthy efficiency without flagship pricing.
Consider Alternatives If
Buyers needing the absolute quietest operation or highest seasonal efficiency should explore 14+ SEER2 systems with variable-capacity compressors.
Installation
Downflow configuration requires horizontal or vertical dropping to lower ductwork, common in basements or utility closets. Line set runs up to 50 feet, with 3/8 inch liquid and 1 1/8 inch suction lines using sweat connections. Plastic or PVC exhaust flue is mandatory. Electrical demand ranges 26.3 to 45 amps at 115V single phase, so standard residential service accommodates it without upgrades in most homes.
Warranty & Reliability
Ten-year warranty on covered parts activates with online registration and provides peace of mind for homeowners. ACiQ backs the system factory-wide, though labor and refrigerant are typically contractor responsibility. Registration takes minutes and should be completed immediately after installation to lock in coverage.
