Review
Goodman's 3-ton gas furnace and air conditioner combo targets contractors and homeowners seeking straightforward, affordable equipment. This upflow A-coil configuration fits standard attic or closet installations in residential homes. At $643 with ENERGY STAR certification, it competes directly against other mid-range split systems. Goodman maintains strong market presence due to parts availability and contractor familiarity, making service calls less expensive than boutique brands.
The furnace delivers 60,000 BTU at 96% AFUE, converting nearly all natural gas or propane into usable heat. The air conditioner produces 34,800 cooling BTU with a 16 SEER1 rating, making it Energy Star qualified. A two-stage burner handles partial-load operation efficiently during shoulder seasons, while the variable-speed ECM blower adapts to actual demand. These specs indicate solid performance for moderate climate zones without premium pricing.
Pros & Cons
Pros
- 96% AFUE furnace efficiency maximizes heating dollars in cold climates, reducing winter fuel costs significantly
- Two-stage burner allows the furnace to run at lower output during mild weather, improving comfort and efficiency
- Variable-speed ECM blower motor adjusts airflow demand, using less electricity than fixed-speed alternatives
- ENERGY STAR certified with lifetime heat exchanger warranty, protecting your largest investment long-term
- PVC exhaust compatible, simplifying venting in retrofit or new construction applications
- AHRI certified for proper matching and performance verification
Cons
- Single-stage condenser limits cooling efficiency on extremely hot days compared to two-stage units
- 73.5 dB noise level is moderately loud, noticeable in quiet homes during operation
- SEER1 rating of 16 is solid but not exceptional for newer equipment, so cooling costs won't be minimal
Who Should Buy
Best For
This system suits homeowners in heating-dominant climates who prioritize furnace efficiency over air conditioning performance. It's perfect for budget renovations or replacements where both heating and cooling are needed but cooling load is moderate.
Consider Alternatives If
Skip this if you live in a hot climate where cooling dominates your annual energy use, as the single-stage 3-ton condenser (34,800 cooling BTU) underperforms against two-stage or inverter-driven competitors.
Installation
Installation requires standard 115V single-phase 60Hz power with 18.7 to 30-amp breaker capacity. The unit weighs 30 pounds, making solo handling feasible. PVC exhaust venting simplifies ductwork, and suction line insulation (3/4 inch thick, 50 feet) comes pre-included. Refrigerant lines use standard 3/8 inch and 7/8 inch connections. Most contractors complete setup in 4-6 hours for experienced crews.
Warranty & Reliability
Goodman backs the heat exchanger with lifetime coverage and provides 10 years of parts warranty upon online registration. This is generous for the price tier, protecting against furnace cracking while covering compressor, fan motor, and other components. Registration is mandatory to activate the extended coverage, so document your purchase immediately.
