// Bottom Line
This Goodman combo system excels for homeowners upgrading older split systems in tight spaces where horizontal configuration is mandatory. The 97% AFUE heating and 13 SEER cooling deliver solid year-round efficiency without premium pricing, making it a smart choice for moderate climates.

Review

Goodman's horizontal gas furnace and air conditioner system combines heating and cooling into one compact unit designed for tight spaces. The SKU ACiQ-36-EHPD-UPG targets contractors and homeowners upgrading older split systems in attics, crawlspaces, and mobile homes. At 3.5 tons with 36,000 cooling BTU and 80,000 heating BTU, this Energy Star qualified system bridges budget and efficiency concerns without premium brand pricing.

The 97% AFUE furnace rating puts this in the ultra-efficient category, meaning nearly all fuel converts to usable heat. Cooling delivers 13 SEER1 efficiency through a single-stage reciprocating compressor and variable-speed ECM blower. The modulating burner adjusts between stages for finer temperature control, while the 115V single-phase 60Hz electrical requirement keeps installation straightforward. R454B refrigerant and plastic PVC flue compatibility meet current environmental standards.

Pros & Cons

Pros

  • 97% AFUE furnace efficiency significantly reduces heating costs compared to standard 80-90% units
  • Modulating burner stages provide precise temperature control and better comfort than single-stage alternatives
  • 13 SEER1 rating qualifies for Energy Star, potentially unlocking utility rebates worth $300-500
  • Variable-speed ECM blower motor adjusts airflow dynamically, improving comfort and reducing runtime noise
  • Horizontal A-coil configuration fits cramped attics, basements, or mobile home spaces where vertical units won't fit
  • R454B refrigerant future-proofs against upcoming EPA phaseouts of older refrigerants

Cons

  • Single-stage compressor cannot match two-stage units in part-load efficiency during mild weather
  • 74 dB noise level acceptable but louder than premium variable-capacity competitors in cooling mode
  • 3.5 ton actual capacity exceeds the 3 ton rating, potentially oversizing for smaller homes and wasting energy

Who Should Buy

Best For

Contractors replacing failed Goodman units GSX130362, GSX130363, or GSX130365 will appreciate the direct compatibility. Homeowners in moderate climates seeking a horizontal furnace-coil combo for attic or basement installation will find the 97% AFUE and 13 SEER efficiency gains meaningful on monthly utility bills.

Consider Alternatives If

Skip this if you need variable-capacity cooling for hot climates or ultra-quiet operation, as single-stage reciprocating compressors cannot match inverter-driven alternatives.

Installation

Horizontal A-coil design requires downflow or horizontal airflow ducting, making it ideal for attic and basement installations. Sweat valve connections use 3/8 inch liquid lines and 3/4 inch suction lines with pre-installed 3/8 inch insulation. The 21 inch by 21.125 inch by 26 inch footprint fits tight spaces where vertical coils cannot. Installation requires 115V single-phase power with a 19.1 to 30 amp breaker.

Warranty & Reliability

Goodman backs this unit with a 10-year parts warranty when you register online after purchase. No labor coverage included, so contractor service calls during year two through ten remain out-of-pocket expenses. This warranty length matches Goodman's mid-tier standard across most product lines and requires proof of professional installation.

Frequently Asked Questions

Why does this say 3 ton but the specs show 3.5 tons? +
The title reflects nominal sizing, but actual tonnage is 3.5 tons, meaning 42,000 BTU cooling capacity. The 36,000 BTU spec shown is the outdoor condenser unit alone. This slight oversizing can increase efficiency in moderate climates but risks short-cycling in mild spring and fall conditions.
Can I install this horizontally in any orientation? +
The unit is configured for downflow/horizontal airflow with the flue exiting right. Improper orientation restricts drainage and exhaust flow, causing condensation backup and premature failure. Always verify airflow and flue direction match your ductwork layout before installation.
How does 97% AFUE compare to my current furnace? +
Most furnaces installed before 2010 operate at 78-80% AFUE, wasting 20-22% of fuel. This 97% unit recovers heat that older models vent outdoors. On an average $1,200 annual heating bill, upgrading saves roughly $240 yearly, paying for itself in 5-7 years.
Is 13 SEER1 good for cooling efficiency? +
13 SEER1 meets mid-range efficiency standards and qualifies for Energy Star rebates. Premium competitors reach 16-18 SEER2, but they cost $2,000-3,000 more. For moderate climates, 13 SEER1 balances reasonable upfront cost with solid long-term savings.
What does the 10-year warranty actually cover? +
It covers defective parts like compressors, motors, and coils. Labor, refrigerant, and ductwork repairs cost extra. Online registration is required within 60 days of installation to activate coverage.
