// Bottom Line
This 2.5-ton Goodman system delivers excellent heating efficiency at 96% AFUE and strong cooling performance with 16 SEER2 rating, making it ideal for homeowners in moderate climates seeking Energy Star certification without premium pricing. The variable-speed ECM motor and two-stage burner provide comfort and operational flexibility.

Review

The Goodman 2.5-ton upflow system represents solid mid-range performance for homeowners balancing efficiency and cost. Manufactured by Online Supply, this unit combines a 96% AFUE furnace with a 16 SEER2 air conditioner in one package. Energy Star certification appeals to conscious buyers and opens eligibility for utility rebates. The variable-speed ECM blower motor distinguishes this system from basic single-speed alternatives, promising more consistent temperature control throughout the heating season.

Performance specs show 40,000 BTU heating capacity with two-stage burner operation and 29,000 BTU cooling output from a scroll compressor. The 1,200 CFM maximum airflow handles the tonnage appropriately without oversizing ducting. At 71.5 dBA, expect noticeable sound during operation, typical for scroll compressor systems at this price point. The A-coil configuration with 3/4-inch suction line insulation minimizes efficiency losses between indoor and outdoor units during the cooling cycle.

Pros & Cons

Pros

  • 96% AFUE furnace efficiency beats most mid-range competitors and reduces heating costs significantly
  • 16 SEER2 cooling efficiency qualifies for Energy Star and many utility rebates
  • Variable-speed ECM blower motor delivers 1,200 CFM maximum airflow with better temperature consistency
  • Two-stage burner and single-stage compressor provide balanced heating and cooling without excessive cycling
  • PVC plastic exhaust flue requirement simplifies installation compared to metal vent systems
  • 10-year warranty with online registration provides solid protection and peace of mind

Cons

  • 71.5 dBA noise level is moderately loud, noticeable during operation in quiet homes
  • Single-stage compressor means less sophisticated cooling modulation than variable-capacity units
  • Spec sheet shows conflicting tonnage claims (title says 2.5 ton, specs list 3 ton) requiring clarification before purchase

Who Should Buy

Best For

Homeowners in moderate climates who prioritize heating efficiency and want Energy Star certification without paying for premium variable-capacity cooling. Contractors installing in upflow configurations appreciate the straightforward PVC vent requirements and reliable Goodman components.

Consider Alternatives If

Buyers in extreme climates needing maximum efficiency tiers, or those sensitive to equipment noise should explore quieter and higher-SEER alternatives.

Installation

Installation favors upflow applications with plastic PVC exhaust flue requirements, reducing material costs compared to metal vent systems. The 115V single-phase 60Hz electrical specification works with standard residential circuits rated for 17.1 to 25 amperes. Unit dimensions of 26 inches tall by 17.5 inches wide by 21 inches deep fit most furnace closets and basement installations. Pre-charged refrigerant lines at 50 feet simplify field connections for certified technicians.

Warranty & Reliability

The 10-year comprehensive warranty applies with free online registration through Goodman. Coverage includes parts and compressor protection, standard for residential systems at this tier. Registration ensures access to warranty claim support and extends eligibility for certain component replacements. Extended warranties from retailers may offer additional protection beyond the manufacturer's baseline coverage.

Frequently Asked Questions

What's the actual tonnage of this system, 2.5 or 3 ton? +
Product documentation shows conflicting specifications. The title states 2.5 ton while specs list 3 ton. The 40,000 BTU furnace and 29,000 BTU cooling output align more closely with 2.5-ton capacity. Verify with the seller before purchase to confirm exact specifications and AHRI certificate number 7368841.
Can I install this in downflow configuration? +
Yes, the spec sheet indicates both upflow and downflow capability. However, confirm your specific ductwork layout matches the A-coil style. Plastic PVC exhaust flue requirement applies regardless of orientation. Your HVAC technician should verify AHRI certification for your exact configuration.
How does 96% AFUE compare to other furnaces? +
96% AFUE places this furnace in the high-efficiency tier, exceeding federal minimum standards of 92% and matching most premium residential units. The two-stage burner contributes to this rating by reducing short-cycling losses. You'll see measurable heating cost reductions compared to 80-90% AFUE systems.
Is 16 SEER2 good cooling efficiency for the price? +
16 SEER2 delivers solid cooling performance and Energy Star qualification at this price point. Variable-capacity systems reach 18-20 SEER2 but cost significantly more. For moderate climates with moderate cooling loads, this efficiency balances operating costs against upfront equipment investment.
Does the 10-year warranty cover refrigerant? +
Standard Goodman warranty covers compressor and parts for 10 years with registration. Confirm whether refrigerant charges are included or require separate coverage. Extended service agreements from installers often add refrigerant replacement protection beyond factory warranty terms.
