// Bottom Line
This ACiQ system delivers solid efficiency for homeowners in mixed climates who need both heating and cooling without overspending. The 96% AFUE furnace and 13 SEER air conditioner balance performance with reasonable upfront costs, making it a smart choice for retrofits and new construction in cold to moderate regions.

Review

The ACiQ 4-ton combo represents a practical middle ground in the HVAC market. You get a 120,000 BTU furnace rated at 96% AFUE paired with a 48,000 BTU cooling unit at 13 SEER, both Energy Star certified. This SKU (ACIQ-48-EHPD-UPG) replaces older Goodman models and addresses the shift toward lower-GWP refrigerants like R454B. At $3,136, it lands between budget units and premium variable-capacity systems, appealing to cost-conscious contractors and homeowners who refuse to sacrifice efficiency.

Furnace performance is the standout here. The two-stage burner and 96% AFUE mean minimal wasted fuel oil escaping up the flue, translating to real monthly savings in heating-dominant regions. The variable-speed ECM blower motor delivers up to 2,000 CFM, reducing overshooting and boosting comfort. On the cooling side, 13 SEER is respectable but not exceptional. The single-stage reciprocating compressor runs at full capacity whenever called, missing opportunities to coast through mild spring and fall days at lower power consumption.

Pros & Cons

Pros

  • 96% AFUE gas furnace means you recover nearly all combustion heat, translating to lower winter utility bills
  • 13 SEER air conditioner with R454B refrigerant meets current EPA standards and earns Energy Star certification
  • Variable-speed ECM blower motor adjusts airflow up to 2000 CFM, improving comfort and reducing runtime noise
  • Two-stage burner on furnace reduces short-cycling and maintains steadier temperatures throughout the heating season
  • 10-year warranty with online registration provides meaningful protection for both components
  • PVC/plastic exhaust flue compatibility simplifies installation in modern homes and reduces venting costs

Cons

  • Single-stage compressor on the air conditioning side cannot modulate capacity, meaning less efficient operation during mild weather
  • 76 dB noise level during cooling is louder than many competing units and may be noticeable in quiet neighborhoods
  • 5-ton condenser paired with 4-ton heating creates a slight mismatch that limits optimization on cooling-heavy climates

Who Should Buy

Best For

Contractors installing complete HVAC systems in cold to moderate climates where heating and cooling demands are roughly balanced, and homeowners replacing failing furnace-AC combos in existing homes. This system excels in areas with real winters where the 96% AFUE furnace payoff justifies the investment.

Consider Alternatives If

Customers in hot climates prioritizing cooling efficiency should look at higher SEER ratings. Those sensitive to operating noise or seeking maximum part-load efficiency will find better matches elsewhere.

Installation

Installation is straightforward for qualified HVAC techs. The unit accepts both natural gas and propane, requires 115V single-phase power with a 26.3 to 45-amp breaker, and uses standard 3/8-inch sweat valve connections. Downflow configuration fits basements and crawl spaces. PVC exhaust flue compatibility eliminates expensive metal ductwork. Technicians should budget 4 to 6 hours for a retrofit, slightly longer for new construction.

Warranty & Reliability

Goodman's 10-year parts warranty activates upon online registration, covering both furnace and air conditioner components. This is industry standard and meaningful protection, though it does not include labor. Registration is quick and typically completed during commissioning. No manufacturer rebates are explicitly advertised, though contractors may access regional utility incentives for Energy Star units.

Frequently Asked Questions

What's the difference between this 4-ton unit and the 5-ton condenser listed in specs? +
The furnace is 4-ton capacity (120,000 BTU heating), but the outdoor condenser is 5-ton (48,000 BTU cooling). This slight mismatch means cooling runs at higher capacity than heating, fine for most mixed climates but slightly oversized if cooling demand dominates your region.
Does this system work with existing ductwork? +
Yes, if your current ductwork is sized for 4-ton airflow (2000 CFM maximum). The variable-speed blower adapts to moderate undersizing, but undersized ducts will reduce efficiency. Have a technician perform a Manual D calculation before installation.
How much will I save monthly compared to an 80% AFUE furnace? +
A 96% versus 80% AFUE furnace saves roughly 16 percentage points on heating fuel. In cold climates burning 1,000 therms annually, expect $150 to $250 annual savings depending on gas prices and home insulation.
Is 13 SEER competitive with other 4-ton units at this price? +
Yes, 13 SEER is standard for this price tier. Higher SEER options (15+) exist but cost $500 to $1,200 more. They pay back only in very hot climates with long cooling seasons. Stick with 13 SEER if heating matters equally in your region.
Will I need to upgrade my electrical panel? +
Only if your current furnace breaker is undersized. This unit needs 26.3 to 45 amps. Most homes have adequate capacity. Electrician inspection takes one hour.
