Review
The Goodman CHPF3743C6 is a horizontal-mount combo system designed for budget-conscious homeowners and service contractors. At 3 tons cooling and 80,000 BTU heating capacity, it slots into the lower-mid range of the market where price matters as much as performance. Goodman has built its reputation on no-frills reliability and parts availability, and this unit reflects that positioning with straightforward engineering and proven components.
Cooling performance reaches 36,000 BTU with a 16 SEER rating, which qualifies for Energy Star but trails premium 18-20 SEER models by measurable margins on summer electric bills. The furnace delivers 80% AFUE efficiency, adequate for moderate climates but noticeably lower than 95% AFUE options common in northern regions. Two-stage operation on both heating and cooling minimizes short cycling, and the variable-speed blower can modulate from 0-2,000 CFM to match actual load conditions, reducing runtime waste.
Pros & Cons
Pros
- 16 SEER rating qualifies for Energy Star certification, reducing annual cooling costs for homes in moderate climates
- 80,000 BTU output with two-stage heating provides adequate warmth for 2,000-2,500 sq ft homes
- Variable speed blower motor adjusts CFM from 0-2,000, improving comfort and reducing energy waste during partial load conditions
- Two-stage compressor and condenser minimize runtime and operating noise at 70.4 dBA
- 10-year full warranty with online registration covers parts and compressor
Cons
- 80% AFUE is entry-level for furnaces; 95% AFUE models save significantly more on heating bills over time
- Requires metal exhaust flue, which adds installation cost in some retrofits where venting flexibility is needed
- R410A or R22 refrigerant compatibility suggests this is not the newest platform; newer units use lower GWP alternatives
Who Should Buy
Best For
Contractors who need reliable equipment for standard residential replacements will appreciate Goodman's consistent performance and easy parts availability. Budget-conscious homeowners in zones with moderate heating demands can justify the lower upfront cost through decent cooling efficiency.
Consider Alternatives If
Skip this if you're prioritizing maximum heating efficiency (95% AFUE models make sense in cold climates) or if you need a premium quiet operation system, as 70.4 dBA is louder than high-end alternatives.
Installation
This horizontal configuration fits tight attic spaces and standard return plenums without special modifications. The unit requires 208-230V single-phase power and breaker sizing between 21.8 and 35 amps, standard for most homes. Metal exhaust flue is mandatory for the furnace side, which may require venting upgrades in some older installations. Dimensions of 21 by 21.125 by 26 inches keep it compact enough to replace existing units without ductwork rework in most cases.
Warranty & Reliability
Goodman backs this system with a 10-year parts and compressor warranty when you register online. Registration is free but required, so homeowners must complete it within 60 days of installation. The warranty is solid for a unit at this price point, covering both major failures and routine part replacements without deductibles. Transfer eligibility depends on Goodman's current policy, so verify if you plan to sell.
