// Bottom Line
This system works best for homeowners in moderate climates who want solid efficiency without premium pricing, or contractors looking for a dependable combo unit for retrofit applications. The 96% AFUE furnace and 13 SEER condenser deliver meaningful energy savings while keeping installation straightforward.

Review

The ACiQ-36-EHPD-UPG represents Goodman's mainstream approach to combined heating and cooling. This 3.5 ton horizontal unit pairs a 100,000 BTU gas furnace with a 36,000 BTU air conditioner in a single assembly, simplifying installation for new builds and replacements. The horizontal configuration targets attic or crawlspace mounting where vertical space is limited. As an Energy Star certified system, it competes directly with mid-tier offerings from Carrier and Lennox.

The furnace hits 96% AFUE efficiency using two-stage combustion, meaning nearly all fuel converts to usable heat. The condenser delivers 13 SEER1 cooling with a reciprocating compressor and sweat fittings for 3/8 inch liquid and 7/8 inch suction lines. The variable-speed ECM blower runs on 115V single-phase power and reaches 2000 CFM maximum, with electrical requirements between 19.1 and 30 amps. AHRI certificate 7368836 validates the matched-unit pairing.

Pros & Cons

Pros

  • 96% AFUE heating efficiency means minimal natural gas waste with 100,000 BTU output
  • 13 SEER1 cooling is Energy Star certified and handles 3.5 ton capacity effectively
  • Variable speed ECM blower motor optimizes airflow between 0-2000 CFM based on demand
  • Two-stage burner reduces short-cycling and improves comfort consistency
  • 10-year warranty with online registration provides solid coverage for the investment

Cons

  • Single-stage cooling compressor lacks modulation for peak efficiency in high-load conditions
  • 74 dB noise level at full capacity may be noticeable in quiet residential settings
  • Reciprocating compressor type is less efficient than scroll designs found in premium units

Who Should Buy

Best For

Contractors managing horizontal installations in attics or crawlspaces will appreciate the compact 21 by 21.125 by 26 inch footprint. Homeowners replacing older Goodman units like the GSX130362 or GSX130363 get direct compatibility with proven reliability at reasonable cost.

Consider Alternatives If

Buyers in very hot climates wanting maximum cooling efficiency should look at higher SEER ratings, and those seeking whisper-quiet operation may want to investigate variable-capacity condensers with lower decibel ratings.

Installation

This horizontal unit requires plastic or PVC exhaust venting, which simplifies routing compared to metal ductwork. Sweat connections mean technicians need soldering skills or should hire licensed installers for refrigerant lines. The 120-pound weight demands two-person handling, especially in confined attic spaces. Pre-charged refrigerant lines up to 30 feet minimize field charging complexity. Plan 4-6 hours for a complete install including ductwork connections.

Warranty & Reliability

Goodman covers parts and compressor for 10 years when you register online after purchase. This is solid mid-range protection that covers manufacturing defects and compressor failure. Labor costs and refrigerant are your responsibility, so factor service call expenses into long-term ownership. Online registration is straightforward and extends coverage significantly beyond the standard limited warranty.

Frequently Asked Questions

What does 96% AFUE mean for my heating bills? +
AFUE measures fuel efficiency as a percentage. At 96%, this furnace converts 96 cents of every fuel dollar into heat, losing only 4% up the flue. Older systems sit around 80%, so upgrading saves approximately 16% on annual heating costs depending on your climate and home size.
Can I install this in my horizontal attic space? +
Yes, this unit is designed for horizontal mounting. Its 26-inch depth and 21-inch height fit most attic framing. You'll need clear ductwork connections above and below, plus accessible service space. Verify your attic can support the 120-pound weight before installation.
How does 13 SEER compare to newer systems? +
13 SEER1 is mid-tier efficiency. Current minimum standards require 14-15 SEER for new units in many regions. You'll save money upfront versus 16+ SEER units, but higher-rated systems reduce cooling costs over time. Best for moderate climates rather than extreme heat zones.
Does this replace my old Goodman GSX130362? +
Yes, this unit explicitly replaces GSX130362, GSX130363, and GSX130365. Connection sizes and mounting patterns align with these models. Have a technician verify existing ductwork and electrical service can handle the new unit before purchasing.
What happens after 10 years of warranty? +
After 10 years, you're responsible for all repairs and parts. Most systems last 15-20 years with regular maintenance. Budget for potential compressor replacement near year 12-15, which typically costs 1500-3000 dollars depending on labor in your area.
