Review
The ACiQ ACIQ-48-EHPD-UPG combines a Goodman gas furnace with integrated heat pump functionality in a compact downflow A-coil configuration. Rated at 4 tons for cooling and 5 tons for heating capacity, this system targets contractors managing equipment replacements and homeowners transitioning from traditional furnace-only setups. The downflow design suits attic or basement installations where horizontal ductwork dominates, making it a practical choice for retrofit applications across varied home configurations.
Performance metrics are straightforward and competitive. The gas furnace delivers 100,000 BTU at 96% AFUE efficiency, meaning minimal energy loss during heating season. The heat pump side contributes 46,000 BTU of cooling capacity with 14 SEER1 rating, qualifying for Energy Star recognition. The scroll compressor operates as single-stage, which prioritizes reliability over modulating efficiency. Multi-speed blower control up to 2,000 CFM allows operators to balance airflow with noise considerations, though the 74 dB operating level remains moderately audible in living spaces.
Pros & Cons
Pros
- Exceptional heating efficiency at 96% AFUE, delivering 100,000 BTU with minimal fuel waste
- 14 SEER cooling efficiency meets Energy Star standards with R454B refrigerant for environmental compliance
- Multi-speed blower motor provides flexible airflow control up to 2,000 CFM for balanced comfort
- 5-ton cooling capacity with single-stage scroll compressor ensures reliable operation in varied climates
- 10-year warranty with online registration covers manufacturing defects and provides contractor peace of mind
Cons
- 74 dB noise level is moderately loud for residential settings, particularly during heating cycles
- Single-stage compressor and burner design lack modulation efficiency of higher-end variable capacity systems
- Requires 26.4 to 40 amp breaker, demanding proper electrical infrastructure that older homes may lack
Who Should Buy
Best For
Contractors replacing failed Goodman GSZ140491 units will appreciate the direct compatibility and streamlined installation. Homeowners in moderate climates seeking balanced heating and cooling performance without premium pricing will find good value in this 4-ton system.
Consider Alternatives If
Those prioritizing ultra-quiet operation or living in high-cooling-demand regions should explore variable-capacity heat pumps rated above 15 SEER.
Installation
Installation requires standard HVAC practices for downflow systems. The unit accepts 3/8 inch liquid lines and 1 1/8 inch suction lines with factory-supplied 1/2 inch insulation rated for 50-foot runs. Electrical connections use 115V single-phase 60Hz power with breaker sizing between 26.4 and 40 amps, depending on local code. PVC exhaust venting simplifies ductwork compared to metal alternatives. Sweat valve connections demand soldering competency or professional installation.
Warranty & Reliability
ACiQ provides 10-year coverage on parts and labor when you register the unit online. This warranty protects against compressor failure, heat exchanger cracks, and component defects, but excludes wear items like filters and refrigerant top-ups. Registration is quick and often unlocks rebate eligibility mentioned in product documentation, adding real financial value beyond the warranty itself.
