// Bottom Line
This Goodman system excels as an entry-level replacement for homeowners and contractors seeking efficient heating without premium pricing. Best suited for upflow installations in moderate climates where 2.5-ton cooling capacity matches existing ductwork.

Review

The Goodman 2.5-ton gas furnace and air conditioner system targets the value segment of the residential HVAC market. At $115, this is positioned as an affordable replacement option for contractors and homeowners managing renovation budgets. Goodman, a Daikin subsidiary, maintains strong contractor relationships through distribution channels like Online Supply. This upflow configuration serves homes with basement furnaces or crawlspace installations, covering roughly 1,000 to 1,400 square feet depending on climate zone and insulation quality.

The furnace delivers 100,000 BTU heating output with an impressive 96% AFUE rating, meaning 96 cents of every dollar spent on gas converts to usable heat. Cooling capacity registers at 29,000 BTU from the air conditioner section with a single-stage scroll compressor. The multi-speed ECM blower motor maxes out at 1,600 CFM and automatically adjusts between stages, reducing runtime noise during partial-load conditions. Two-stage burner firing provides smoother operation than single-stage alternatives, though the system still operates at 71.5 dB under full load.

Pros & Cons

Pros

  • 96% AFUE furnace efficiency significantly reduces heating costs compared to 80-90% units
  • Two-stage burner provides better comfort and modulation than single-stage alternatives
  • Multi-speed ECM blower motor optimizes airflow and reduces electricity consumption
  • Energy Star certified, qualifying for utility rebates in many regions
  • Two-piece construction with flexible piping makes installation manageable in tight spaces
  • PVC exhaust compatibility eliminates expensive chimney modifications

Cons

  • Cooling tonnage mismatch: specs list both 2.5-ton and 3.5-ton claims, creating confusion about actual capacity
  • SEER ratings inconsistent between product title (15 SEER) and specs (16 SEER1), though newer SEER2 standard not provided
  • Single-stage condenser limits cooling efficiency compared to two-stage alternatives at similar price points
  • 71.5 dB noise level runs louder than high-efficiency competitors, noticeable during operation

Who Should Buy

Best For

Budget-conscious homeowners replacing a failed system in homes with upflow ducting and contractors installing affordable equipment in rental properties or first-time flip projects. Ideal for areas where heating demands outweigh cooling needs.

Consider Alternatives If

Anyone in hot climates relying heavily on air conditioning should consider two-stage cooling units, and buyers needing whisper-quiet operation should look at models rated below 70 dB.

Installation

Installation requires standard 208/230V single-phase power with minimum 17.1-amp breaker capacity. The upflow/downflow flexible design accommodates both basement and attic mounting. Plastic PVC exhaust piping eliminates masonry flue costs, though proper condensate drainage to existing plumbing is critical for 96% AFUE efficiency. The 26-inch height, 21-inch width, and 21-inch depth fit standard furnace closets. Refrigerant line sets come in 50-foot lengths with pre-installed 3/4-inch suction line insulation.

Warranty & Reliability

Goodman provides 10 years parts coverage with online registration, a solid standard in the mid-tier segment. The evaporator coil carries separate warranty coverage included in documentation. Registration is straightforward but mandatory to activate protection. No labor coverage is included, so technician service calls are the homeowner's responsibility. Compare this to premium brands offering 10-year compressor-only or limited lifetime warranties on select components.

Frequently Asked Questions

The listing shows both 2.5-ton and 3.5-ton ratings. Which is correct? +
The product title claims 2.5 tons, but specifications list 3.5-ton tonnage with 29,000 BTU cooling output. This discrepancy suggests either documentation error or a mixed component pairing. Contact Online Supply with your SKU (LS38783850) before purchase to confirm actual cooling capacity for proper equipment matching.
Can this furnace vent through plastic PVC pipe instead of a traditional chimney? +
Yes, the unit requires PVC exhaust piping, a major advantage eliminating expensive chimney work. However, ensure your home's existing venting structure can accommodate horizontal or vertical PVC installation. Improper slope causes condensate backup into the furnace, voiding efficiency gains and warranty coverage.
How does 96% AFUE compare to other furnaces at this price point? +
Most competitor units in the $100 to $150 range offer 80 to 92% AFUE. This 96% efficiency saves approximately $150 to $200 annually on heating costs in cold climates, recovering the price premium in 12 to 18 months through reduced gas consumption.
Is the single-stage air conditioner a limitation compared to two-stage models? +
Single-stage cooling runs continuously at full capacity until temperature setpoint is reached, cycling on and off. Two-stage condenser alternatives modulate capacity, improving comfort and efficiency on moderate days. For cooling-dominant climates, two-stage justifies 15 to 20 percent higher upfront cost through reduced run times.
Does online registration for the 10-year warranty involve any fees? +
No, Goodman's 10-year warranty registration is complimentary through their online portal. You'll need the serial number and installation date. Keep your receipt as proof of purchase. Registration typically completes in minutes and immediately activates coverage.
