// Bottom Line
This 2.5-ton system delivers solid efficiency with a 96% AFUE furnace and 13 SEER air conditioner, making it ideal for homeowners upgrading existing systems or installing in attics and crawlspaces where vertical equipment won't fit. The horizontal A-coil design and PVC flue compatibility simplify retrofits.

Review

The ACiQ 2.5-ton horizontal system combines a Goodman gas furnace and air conditioner into a space-efficient package designed for installations where traditional upflow configurations won't work. This unit addresses a real market need, particularly among contractors handling attic and crawlspace retrofits. The horizontal A-coil design maintains proper refrigerant circulation while fitting tight overhead spaces, a practical advantage that standard vertical equipment cannot match.

Efficiency numbers tell the real story here. The furnace delivers 96% AFUE across 40,000 BTU of heating capacity, meaning 96 cents of every heating dollar actually warms your home. The air conditioner provides 30,000 BTU cooling at 13 SEER with a reciprocating compressor and single-stage operation. The 800 CFM maximum airflow with multi-speed ECM blower gives adequate circulation for 2.5-ton capacity without excessive noise, though the 73 dB operating level is measurably louder than variable-capacity competitors.

Pros & Cons

Pros

  • 96% AFUE furnace efficiency reduces heating costs by approximately 4% compared to 92% AFUE units
  • 13 SEER air conditioner with Energy Star certification for reliable summer cooling
  • Horizontal configuration fits attics, crawlspaces, and basements where upflow units cannot
  • Multi-speed ECM blower motor reaches 800 CFM for balanced airflow in medium-sized homes
  • 10-year warranty with online registration provides peace of mind on both heating and cooling components

Cons

  • Single-stage compressor cannot modulate cooling capacity, resulting in slightly lower efficiency during partial-load conditions
  • 73 dB noise level runs louder than variable-capacity competitors, noticeable near outdoor unit placement
  • R454B refrigerant requires EPA certification for service technicians, limiting repair options in some rural areas

Who Should Buy

Best For

Homeowners in homes with attics or tight mechanical spaces who need a balanced heating and cooling upgrade without major ductwork changes. Contractors handling retrofit projects in older homes where furnace orientation is constrained by space limitations.

Consider Alternatives If

Buyers seeking absolute whisper-quiet operation or homeowners in areas with very limited HVAC service availability should explore higher-SEER variable-capacity alternatives.

Installation

Installation complexity depends on existing ductwork orientation. The horizontal design accepts both upflow and leftward discharge, with PVC flue requirements simplifying new vent runs compared to metal alternatives. Suction line insulation measures 3/4 inches thick, and refrigerant lines use 3/4-inch and 3/8-inch connections with sweat valve fittings. 120-pound weight suits overhead installation without reinforcement in most homes.

Warranty & Reliability

ACiQ backs this system with 10 years coverage on both furnace and air conditioner components when you register online. The registration requirement is straightforward and typically takes five minutes. Coverage includes compressor, heat exchanger, and major components, though labor costs remain your responsibility.

Frequently Asked Questions

Why choose 13 SEER over higher-efficiency models? +
13 SEER balances upfront cost against operational savings. For moderate climates, the energy difference between 13 and 16 SEER recovers in 10-12 years. Single-stage simplicity also means fewer components to fail, supporting long-term reliability in residential applications.
Will this system fit in my attic alongside existing ductwork? +
Yes. The horizontal A-coil design specifically accommodates attic installation. Verify your space allows 50 inches length, 26 inches depth, and 17.5 inches height. The 120-pound weight requires adequate joists or bracing, a detail your installer should assess during equipment selection.
How does 96% AFUE affect my monthly heating bill? +
A 96% unit loses only 4% of fuel as exhaust heat, compared to 8% loss in 92% models. On annual heating costs of $1,200, you save approximately $48 per year. Payback extends longer in mild climates but accelerates in northern zones with extended heating seasons.
Can I use this system to replace my existing furnace and AC separately? +
Absolutely. This combined system works as a complete replacement for older split systems. Ensure your current refrigerant lines, ductwork diameter, and electrical panel support 16.7 to 25-amp breaker requirements. Your HVAC contractor should verify compatibility before installation.
What does the 10-year warranty actually cover? +
The warranty covers manufacturing defects in the compressor, heat exchanger, and major components. Labor is your responsibility. Online registration is required to activate coverage. ACiQ honors claims through authorized dealers within the warranty period.
