Review

Goodman's 2.5-ton gas furnace and air conditioner combo delivers competent performance at an accessible price point, currently listed at $2,787. This is an upflow configuration designed for standard residential installations. The system combines an 80,000 BTU furnace with a 29,000 BTU cooling capacity, making it suitable for medium-sized homes in temperate regions. Goodman maintains strong contractor loyalty through straightforward design and reasonable cost of ownership.

The furnace achieves 80% AFUE with two-stage burner control, while the air conditioner rates at 16 SEER2 with a scroll compressor. Variable-speed blower technology adjusts airflow between 0 and 2,000 CFM based on heating and cooling demand, improving comfort and reducing energy waste. The unit runs on natural gas or propane and handles standard R410A refrigerant. Energy Star certification means it meets EPA guidelines for efficiency, qualifying homeowners for utility rebates in many states.

Pros & Cons

Pros

  • Variable-speed blower motor delivers better comfort and efficiency than single-stage alternatives, cycling output to match actual demand
  • 16 SEER2 rating on the air conditioner significantly exceeds the 15 SEER advertised spec, offering measurable cooling efficiency gains
  • Two-stage burner in furnace allows for modulated heating, reducing short-cycling and improving comfort during mild weather
  • Energy Star certified system qualifies for utility rebates in many regions, offsetting purchase price
  • 10-year warranty with online registration provides solid coverage for major components at this price point

Cons

  • 80% AFUE is minimum standard for modern furnaces; higher efficiency models reach 95% AFUE but cost more upfront
  • Single-stage scroll compressor operates at full capacity or off, lacking the fine modulation of two-stage designs
  • 71.5 dBA noise level is moderate to loud during operation, noticeable in quiet homes or bedrooms nearby

Who Should Buy

Best For

Installation

The upflow configuration works with standard ducting and requires a metal exhaust flue for furnace venting. Electrical needs are modest, 120V single-phase 60 Hz with 17.1 to 25 amp breaker capacity. The compact footprint, 22 inches tall and 24.5 inches wide, fits most utility closets and basements. Technicians familiar with Goodman equipment will complete installation quickly, typically four to six hours for experienced crews.

Warranty & Reliability

Online Supply provides a 10-year warranty on parts and compressor when you register the system online. This standard coverage protects against manufacturing defects but excludes wear items and labor costs. Registration is straightforward and takes minutes. The warranty period is respectable for mid-market equipment, though premium brands sometimes offer longer terms.

Frequently Asked Questions

Why does the spec sheet show 3.5 tons when the product title says 2.5 tons? +
This appears to be a spec sheet error from the supplier. The title, pricing, and cooling capacity of 29,000 BTU all confirm this is a 2.5-ton unit. Verify tonnage with your installer and the AHRI certificate number 204633307 before ordering to ensure accuracy.
Can I install this in a crawlspace or attic instead of upright? +
This is configured for upflow or downflow operation. The downflow capability allows horizontal installation in attics or crawlspaces. Ensure adequate clearance around the unit and proper return air ducting. Consult the installation manual before choosing non-standard placement.
How much will this system reduce my energy bills? +
A 16 SEER2 air conditioner and 80% AFUE furnace with variable-speed blower typically cut cooling costs 15-25% versus 13 SEER single-stage units. Heating savings depend on your climate and thermostat settings. Energy Star certification often qualifies you for $300 to $1,500 in rebates.
How does this compare to higher-efficiency Goodman models? +
Goodman's premium lines reach 96% AFUE and 18-21 SEER2 but cost $4,000 to $6,000 more. This unit balances practical efficiency with affordability. Choose premium models only if you plan to stay 15+ years and want maximum bill reduction.
What does the 10-year warranty actually cover? +
Parts and compressor defects are covered for 10 years with registration. Labor, shipping, and maintenance are not included. Check your specific warranty document for exact exclusions and claim procedures before installation.
