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
Best For
Contractors building affordable system packages for rental properties or first-time buyers. Homeowners in moderate climates seeking straightforward equipment that won't break their budget but delivers dependable performance for 10-15 years.
Consider Alternatives If
Anyone in extreme cold climates needing maximum heating efficiency, or those prioritizing whisper-quiet operation should explore alternatives.
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.
