2.5 Ton 15 SEER 96% AFUE 60,000 BTU Goodman Gas Furnace and Air Conditioner System - Horizontal Review 2026

// Bottom Line

This Goodman system is best for homeowners upgrading from older single-stage equipment who want strong efficiency without premium pricing. The 96% AFUE heating and 16 SEER cooling make it a solid all-around choice for moderate climates where both seasons matter equally.

Review

This Goodman horizontal system combines a 60,000 BTU furnace with a 29,000 BTU condenser unit into one integrated package designed for downflow or horizontal attic installations. Priced at $2,466, it targets the middle market where efficiency matters but premium two-stage features stay out of budget. Goodman maintains solid contractor support and parts availability across most regions, making long-term ownership straightforward for HVAC service technicians.

The furnace delivers 96% AFUE through modulating two-stage burners and sealed combustion, a genuine jump from 80-85% standard equipment. Cooling pulls 16 SEER2 from a scroll compressor and A-coil configuration, though the single-stage design means it runs at full load or stops completely. The variable-speed ECM blower motor (maximum 1200 CFM) adjusts to demand, improving seasonal efficiency and reducing runtime noise compared to fixed-speed alternatives. Energy Star certification validates these claims across third-party testing.

Pros & Cons

Pros

96% AFUE furnace efficiency reduces heating costs by 15-20% versus 80% AFUE baseline models
16 SEER2 cooling performance exceeds the stated 15 SEER marketing claim, delivering real energy savings
Variable-speed ECM blower motor optimizes comfort and efficiency across partial-load conditions
Two-stage burner minimizes short cycling and improves temperature consistency in heating mode
10-year comprehensive warranty with online registration covers parts and labor appropriately

Cons

Single-stage compressor cannot modulate cooling capacity, running at full capacity or off
71.5 dB noise level registers as moderately loud, noticeable during compressor operation
3-ton cooling capacity exceeds the advertised 2.5-ton specification, creating sizing mismatch confusion

Who Should Buy

Best For

Homeowners in mixed climates needing reliable heating and cooling without spending $3,500+ on modulating systems. Contractors building mid-range packages for moderate-income customers who value efficiency rebates and straightforward serviceability.

Consider Alternatives If

Anyone in hot climates where single-stage cooling creates inefficiency, or noise-sensitive applications near bedrooms and living spaces where 71.5 dB becomes problematic.

Installation

Installation requires 115V single-phase 60Hz power, 17.1 to 25-amp breaker sizing, and standard refrigerant lines (3/8 inch liquid, 7/8 inch suction with 3/4 inch insulation). The unit weighs 30 pounds and measures 34.5 inches high, 17.5 inches wide, and 28.75 inches deep, fitting tight attic spaces. PVC exhaust flue must be properly sized and pitched for condensate drainage. Ductwork and electrical work require licensed contractors in most jurisdictions.

Warranty & Reliability

Ten-year comprehensive warranty covers parts and labor when registered online through Goodman. This compares favorably to five-year baseline coverage, effectively doubling replacement protection for compressors and heat exchangers. Registration takes minutes and requires proof of purchase. Online Supply, the distributor, backs Goodman's warranty terms without additional dealer markups.

Frequently Asked Questions

Does this 2.5-ton system really cool 3 tons of capacity? +

The spec sheet lists both 2.5 tons marketing and 3 tons actual cooling tonnage. You receive 29,000 BTU cooling (roughly 2.4 tons), making the 3-ton spec incorrect. Verify actual tonnage with your installer before purchase to ensure proper load matching and avoid undersizing or oversizing issues.

What refrigerant should I buy for this unit? +

The system accepts either R410A or R22, though R22 is being phased out and costs significantly more. R410A is the standard choice and standard for new installations. Confirm compatibility with your existing outdoor condenser before servicing, as mixing refrigerants damages compressors and voids warranty.

How much will I save on heating costs versus an 80% AFUE furnace? +

A 96% AFUE unit saves roughly 16-20% on annual heating fuel compared to 80% AFUE baseline equipment. At $1,200 annual heating costs, expect $190-240 yearly savings. Payback occurs in 8-10 years depending on energy prices, weather, and actual usage patterns in your climate zone.

Is 71.5 dB noise level considered loud for an HVAC system? +

Yes, 71.5 dB ranks as moderately loud, comparable to a vacuum cleaner or busy traffic. Two-stage compressors and variable-speed blowers typically run 65-68 dB. If you value quietness near bedrooms, look for systems rated 68 dB or lower, or position the unit away from occupied spaces.

Do I need ductwork modifications for this horizontal unit? +

Horizontal A-coil systems require supply and return ducts sized for 1200 CFM maximum airflow. Existing ductwork may need cleaning and sealing if transitioning from older equipment. A load calculation by your HVAC contractor ensures proper duct sizing, preventing efficiency loss and comfort complaints.
