Review
The Goodman CAPF3636C6 is a competent mid-market gas furnace and air conditioner combo targeting the replacement retrofit market. At 92% AFUE and 14 SEER, it sits comfortably above entry-level equipment but below premium modulating systems. This upflow configuration with PVC exhaust makes it well-suited for homes where traditional chimneys aren't available and utility space is tight. Goodman's established dealer network and straightforward mechanical design appeal to contractors focused on reliability over cutting-edge features.
Performance specs show a 100,000 BTU heating output with single-stage burner operation and a multi-speed blower reaching 2,000 CFM maximum. The cooling side delivers 24,000 BTU through a scroll compressor rated for single-stage cycling. The 92% AFUE means roughly 8 cents more efficiency per heating dollar versus 80% units, adding up over seasons in northern climates. At 71 dB, noise levels are moderate, acceptable for basements but noticeable in utility rooms adjacent to living spaces. Electrical requirements are straightforward at 208/230V single-phase, 60 Hz, with breaker sizing between 14.3 and 25 amps.
Pros & Cons
Pros
- 92% AFUE furnace efficiency reduces heating costs compared to 80% units, particularly valuable in colder climates
- 14 SEER air conditioner meets Energy Star adjacency and handles 24,000 BTU cooling on 2-ton nominal capacity
- Multi-speed blower motor allows system to adapt airflow, improving comfort and reducing runtime noise compared to single-speed alternatives
- Compact footprint measures 21 by 21 by 22 inches, fitting tight utility closets and retrofit installations
- PVC exhaust flue compatibility eliminates costly chimney modifications on older homes
- 10-year parts warranty with online registration provides meaningful protection at this price point
- Single-stage burner and scroll compressor are reliable, field-proven components with strong contractor support
Cons
- Spec sheet lists tonnage as 3 Ton but cooling output is only 24,000 BTU (standard 2-ton capacity), creating potential confusion during sizing
- 71 dB noise level runs slightly louder than premium competitors, noticeable during heating cycles in quiet homes
- Not Energy Star certified despite respectable efficiency ratings, missing promotional rebates in some utility programs
- Single-stage compressor and burner mean less granular capacity modulation than higher-end systems
- R410A or R22 refrigerant compatibility noted without clarity on which the unit ships with, requiring verification
Who Should Buy
Best For
Contractors installing replacement systems in residential upflow applications where existing ductwork and utility space are constrained. Homeowners in moderate climates seeking efficiency improvements over 10-year-old equipment without spending premium dollars on modulating stages or variable-speed components.
Consider Alternatives If
Buyers in Energy Star rebate programs, homes requiring downflow-only configuration, or those prioritizing whisper-quiet operation should evaluate alternatives, as this unit's single-stage design and 71 dB output have limitations.
Installation
Installation favors contractors familiar with standard split systems. The compact 21 by 21 by 22 inch cabinet fits most utility closets, and the multi-position design handles upflow or horizontal orientations. PVC exhaust flue requirements simplify venting through exterior walls, eliminating costly masonry work. Refrigerant line sizes are 3/8 inch liquid and 3/4 inch suction, standard gauges reducing specialized tooling needs. Indoor coil pairing and outdoor condenser matching must follow Goodman specifications to maintain warranty.
Warranty & Reliability
Goodman covers parts for 10 years when owners complete online registration at purchase. This surpasses the typical 5-year baseline and reflects the brand's confidence in component reliability. Compressor coverage is included, though labor and refrigerant charges fall to the service contractor. Activation is straightforward and required within a defined period, so buyers should not delay registration after installation.
