// Bottom Line
This horizontal Goodman system works best for contractors needing reliable equipment in tight attic or basement spaces without premium pricing. The 80% AFUE furnace and 17 SEER cooling deliver solid year-round performance for moderate climates, and the $2160 price point makes it competitive for budget-conscious homeowners upgrading older systems.

Review

Goodman's horizontal 3-ton system lands at an attractive price point for contractors and homeowners trading premium features for solid core performance. SKU CHPF3743D6 combines an 80% AFUE furnace pushing 80,000 BTU with a 3-ton air conditioner delivering 35,000 BTU cooling capacity. The horizontal orientation fits tight attic or basement installations where vertical equipment won't work, and the compact footprint, 63 pounds total weight, makes handling manageable on retrofit jobs. This is genuine workhorse equipment without flashy extras.

Performance numbers tell a practical story. The furnace burns propane or natural gas with two-stage burner control, meaning it runs at reduced capacity during shoulder seasons instead of cycling on and off constantly. Cooling delivers 17 SEER efficiency with a scroll compressor and two-stage condenser, matching modern efficiency standards without premium pricing. A variable-speed blower motor adjusts to actual heating and cooling demand, improving comfort and reducing electricity costs compared to fixed-speed alternatives. Maximum 2000 CFM airflow suits the 3-ton capacity well.

Pros & Cons

Pros

  • Aggressive $2160 price point for a complete 3-ton heating and cooling system
  • Two-stage burner and two-stage compressor allow efficient partial-load operation during mild weather
  • Horizontal configuration fits tight spaces, 21.125 inches wide and 24.5 inches tall
  • Variable-speed blower motor optimizes airflow and reduces energy waste
  • Energy Star certified with 17 SEER cooling efficiency
  • 80,000 BTU heating capacity handles most residential heating needs

Cons

  • 80% AFUE furnace lags behind high-efficiency 95% systems, costing more to heat over time
  • 17 SEER rating is solid but not class-leading compared to 18+ SEER competitors
  • 71 dB noise level audible during operation, typical for two-stage equipment

Who Should Buy

Installation

The horizontal configuration requires proper ductwork connection at the inlet and outlet, with metal exhaust flue requirement for safe gas venting. Electrical demand runs 208/230V single-phase at 60 Hz, with breaker sizing between 21.9 and 35 amps depending on local code. Refrigerant lines use 3/8 inch liquid and 7/8 inch suction connections with sweat-type valves, standard for most residential installations. Installation manual and specs sheet are available as PDFs.

Warranty & Reliability

Goodman backs this system with a 10-year parts warranty when you register online, a straightforward approach that covers major components like the compressor and heat exchanger. No additional evaporator coil warranty documentation is provided beyond standard coverage. Registration takes minutes and protects your investment if failure occurs, though labor and refrigerant charges are your responsibility after the warranty period.

Frequently Asked Questions

How much will this system cost to operate yearly compared to a 95% AFUE furnace? +
An 80% AFUE furnace wastes 20% of fuel energy, roughly 15-25% higher heating costs than a 95% AFUE model in cold climates. Over 10 years, that gap could reach $500-1200 depending on heating degree days and gas prices, offsetting the lower purchase price for many buyers.
Can this horizontal unit connect to existing ductwork in a standard attic installation? +
Yes, horizontal configuration is standard for attic placement. Ensure adequate clearance around the 21.125 inch width and 26 inch depth. The metal exhaust flue must vent safely to the exterior, typically through the roof or gable wall, following local codes.
Is 17 SEER cooling efficiency good for the price point? +
Absolutely. 17 SEER meets Energy Star requirements and keeps cooling costs reasonable. Some competitors offer 18-20 SEER at higher price tags, but the $2160 price means this system reaches better overall value for budget-conscious buyers accepting slightly higher electricity costs.
How does the two-stage burner improve comfort compared to single-stage furnaces? +
Two-stage burners run at low capacity (Stage 1) during mild weather, reducing on-off cycling and temperature swings. Full capacity (Stage 2) activates only during cold snaps. This creates steadier indoor temperatures and quieter operation than constant cycling typical of single-stage furnaces.
What does the 10-year warranty actually cover if my compressor fails? +
Parts replacement only. Goodman covers the compressor, heat exchanger, and other internal components. You pay for labor to remove and install a replacement compressor, plus refrigerant recharge costs, typically $300-600 depending on your location.
