2 Ton 14 SEER 92% AFUE 100,000 Goodman Gas Furnace and Air Conditioner System - Upflow Review 2026

// Bottom Line

This Goodman system is ideal for budget-conscious homeowners replacing an older furnace and AC unit together, particularly in moderate climates where 2-ton cooling capacity matches existing ductwork. At $647, you're getting respectable efficiency with a trusted manufacturer, though don't expect premium features or high-efficiency ratings.

Review

The Goodman CAPF3743C6 is a straightforward 2-ton combined gas furnace and air conditioning unit positioned in the value segment of the residential HVAC market. With a $647 price tag and 100,000 BTU heating capacity, this system targets budget-conscious homeowners and contractors who prioritize affordability without expecting premium features. Goodman's reputation for durability in light commercial and residential applications gives this unit credibility, though it competes directly with Lennox and Carrier entry-level offerings.

The 92% AFUE rating on the heating side outperforms standard 80% efficiency furnaces by roughly 12 percentage points, translating to meaningful annual fuel savings in colder months. On cooling, the 14 SEER rating delivers 24,000 BTU capacity through a single-stage scroll compressor, handling moderate climate demands efficiently. The multi-speed blower motor automatically adjusts airflow up to 2000 CFM, reducing runtime during partial load operation. At 71 dB, noise output is perceptible but acceptable for basement or utility closet placement.

Pros & Cons

Pros

92% AFUE furnace efficiency delivers real heating savings compared to 80% AFUE units, roughly 12% lower fuel costs annually
14 SEER cooling efficiency is solid for the price point, well above baseline 13 SEER requirements
Multi-speed blower motor adapts to different ductwork configurations and reduces energy waste during partial heating cycles
PVC flue compatibility simplifies venting installation and reduces material costs versus metal flue systems
Scroll compressor is proven reliable with good warranties and widely available replacement parts
2-ton capacity matches most existing residential ductwork without expensive modifications

Cons

Single-stage burner and compressor mean less modulation, leading to slightly higher short cycling and energy waste in mild weather
71 dB noise level is perceptible and louder than some competitors, noticeable in quiet living spaces
No Energy Star certification indicates this doesn't meet the highest efficiency tiers available in the market
Refrigerant flexibility (R410A or R22) could create confusion during service calls and future repairs

Who Should Buy

Best For

Homeowners in moderate climate zones replacing aging furnace and AC units simultaneously who value affordability and don't need premium efficiency features. Contractors installing systems in rental properties or first-time replacements will appreciate the straightforward design and low price point.

Consider Alternatives If

Energy-conscious buyers in extreme climates, SEER2-focused consumers, or anyone seeking variable-capacity cooling should look at higher SEER systems or dual-stage options instead.

Installation

Installation requires 208/230V single-phase 60Hz power with breaker sizing between 14.3 and 25 amps, making it compatible with most residential electrical panels. The upflow/downflow configuration accommodates both basement and attic placement. PVC plastic venting simplifies flue installation by avoiding metal ductwork. Standard refrigerant line sizes (3/8 inch liquid, 7/8 inch suction) and the A-coil style integrate with typical residential ductwork without extensive modifications.

Warranty & Reliability

Goodman provides a 10-year parts warranty upon online registration, covering compressor, scroll pump, and major components. This is competitive for the price tier but requires activation to be valid. The coverage excludes labor and routine maintenance, so budget accordingly for service calls during the warranty period. Registration typically takes minutes online through Goodman's portal.

Frequently Asked Questions

How much will this system reduce my heating costs compared to an old 80% AFUE furnace? +

The 92% AFUE rating means approximately 12% more of your fuel becomes usable heat. On a $1,200 annual heating bill, expect $140 to $160 in annual savings depending on local gas rates and climate severity. Payback typically occurs within 5 to 7 years.

Can this furnace work with my existing ductwork and AC lines? +

Most likely yes. The 2-ton capacity and A-coil configuration are standard residential sizes. Verify your current system tonnage and coil type before purchase. The 3/8 inch and 7/8 inch refrigerant line sizes are universal, requiring only a flush if replacing R22 with R410A.

Is 14 SEER cooling efficiency good enough for hot climates? +

14 SEER is adequate for moderate climates but marginal for regions with 100+ degree summers. Consider upgrading to 16+ SEER for high-heat areas where the unit runs continuously during peak season, as lower SEER ratings will strain the system and increase energy costs significantly.

How does this compare to budget options from Lennox or Carrier? +

Goodman typically undercuts competitors by 15% to 20% on price while matching efficiency ratings. Lennox and Carrier offer slightly quieter units and better service networks, but Goodman's warranty and parts availability are equally strong. Choose Goodman for cost savings if your local technician supports the brand.

What does the 10-year warranty actually cover if something breaks? +

Parts replacement for compressor, blower motor, and internal components is covered. Labor costs are your responsibility. Online registration is mandatory, and coverage excludes damage from improper installation, low refrigerant, or lack of maintenance.
