Review
The Goodman 4 Ton 14 SEER furnace and AC combo addresses a specific market need: reliable, efficient heating and cooling for contractors managing space constraints. Online Supply's offering bundles a gas furnace with an air conditioning unit, designed as a complete downflow system. This configuration works well in basements and mechanical closets where traditional upflow installations won't fit. The unit carries ENERGY STAR certification, signaling compliance with current efficiency standards.
Performance metrics show a 96% AFUE furnace delivering 48,000 BTU of heating output with a single-stage burner. Cooling capacity matches at 48,000 BTU with 14 SEER efficiency and a scroll compressor using R410A refrigerant. The multi-speed blower reaches 2000 CFM maximum, supporting adequate airflow distribution. Operating at 74 dBA, it's audible but not exceptional. The 1-phase 208/230V electrical requirement demands standard residential breakers between 26.4 and 45 amps.
Pros & Cons
Pros
- 96% AFUE efficiency with 48,000 BTU heating output reduces gas consumption significantly
- 14 SEER cooling (16 SEER1 rating) paired with R410A refrigerant meets modern standards
- Compact 30x21x21 inch footprint works in downflow/horizontal configurations for tight spaces
- Multi-speed blower motor and 2000 CFM maximum airflow optimize comfort and distribution
- ENERGY STAR certified with 10-year warranty including online registration coverage
Cons
- Single-stage burner and condenser lack the modulation benefits of two-stage systems for efficiency
- 74 dBA noise level runs louder than premium models, noticeable during operation
- 5-ton condenser paired with furnace shows potential rating mismatch requiring verification
Who Should Buy
Best For
Contractors and homeowners replacing 80-85% AFUE systems in basements, utility closets, or confined horizontal installations. This system fits tight spaces while delivering measurable energy savings without premium pricing.
Consider Alternatives If
Those seeking ultra-quiet operation or maximum modulation efficiency should consider two-stage systems, which offer better part-load performance in milder weather months.
Installation
Downflow/horizontal configuration requires plastic PVC exhaust venting, flue exiting right side. The 30x21x21 inch dimensions fit tight spaces easily. Refrigerant lines use standard 3/8 inch liquid and 1 1/8 inch suction sizes with 1/2 inch insulation and 50-foot length included. Sweat-type valve connections demand basic soldering skills or professional installation. Multi-speed blower wiring varies by configuration.
Warranty & Reliability
Goodman provides 10 years comprehensive coverage upon online registration. This extended warranty covers parts and labor, protecting against compressor failure and heat exchanger defects. Registration is essential, so save documentation. Limited component coverage details require checking manufacturer terms, but 10-year protection is strong for this price tier.
