Review
The Goodman CHPF3636B6 combines heating and cooling capability in a horizontal format designed for tight spaces. This system targets homeowners upgrading from outdated single-stage equipment and seeking energy savings without replacing ductwork. Goodman's reputation for reliability in mid-range HVAC markets makes this an attractive retrofit option. The combination of 97% AFUE furnace efficiency and 16 SEER cooling places it in the efficient tier, though not premium high-efficiency class.
Performance specs are genuinely strong here. The furnace delivers 80,000 BTU heating with modulating burners that fire in stages, reducing wasted fuel on mild days. Cooling reaches 24,000 BTU (contradicting the 2 ton title), with a scroll compressor and two-stage condenser design. The variable-speed ECM blower maxes out at 1,200 CFM, allowing precise airflow matching. At 71 dB, operation remains reasonable for residential settings. Energy Star certification confirms the efficiency claims are EPA-verified.
Pros & Cons
Pros
- 97% AFUE furnace efficiency significantly reduces natural gas or propane consumption compared to older 80-85% models
- 16 SEER cooling with two-stage compressor balances performance and efficiency without excessive noise at 71 dBA
- Modulating burner stages provide precise heat control and reduce short cycling on mild days
- Horizontal configuration fits attics and crawl spaces where vertical units won't fit
- Variable-speed ECM blower motor adapts airflow to demand, improving comfort and reducing runtime costs
Cons
- Specs list 3 ton cooling capacity while product title claims 2 ton, creating clarity issues for contractors
- Price of $115 appears unrealistically low and may not reflect actual installed system cost with labor and ductwork
- PVC exhaust requirement limits installation flexibility in older homes with masonry chimneys
Who Should Buy
Best For
Homeowners replacing 15+ year old furnace and AC systems in attics or horizontal installations where space constraints exist. This unit works well for moderate climates where modulating burners justify efficiency gains over single-stage competitors.
Consider Alternatives If
Anyone needing a vertical upflow system for basement installations, or homes requiring masonry chimney venting without PVC adapter kits.
Installation
Horizontal orientation suits attics and crawl spaces where vertical clearance is limited. The unit weighs 50 lbs and measures 21.125" tall by 17.5" wide by 26" deep, fitting standard 24-inch attic joists. Refrigerant piping uses 3/8" liquid and 7/8" suction lines with sweat connections, standard for technicians. Electrical requires 115V single-phase 60 Hz service with 15.7 to 20 amp breaker. PVC exhaust venting is mandatory, incompatible with existing masonry flues.
Warranty & Reliability
Goodman provides a 10-year parts warranty upon online registration, covering compressor and major components. This is solid for the mid-range market, though premium brands often offer 12-year or longer coverage. Registration is required to activate full warranty protection, so save documentation. Coverage begins from installation date, not purchase date.
