// Bottom Line
This Goodman system is ideal for homeowners upgrading from single-stage equipment who want measurable energy savings without premium pricing. The 96% AFUE furnace and 18 SEER1 air conditioner deliver solid efficiency gains, especially in mixed climates where both heating and cooling run regularly throughout the year.

Review

Goodman's three-ton upflow gas furnace and air conditioning system targets the middle market, where homeowners want meaningful efficiency upgrades without boutique pricing. This unit pairs a 60,000 BTU furnace with a 35,000 BTU air conditioner in a compact vertical configuration. Online Supply rates this as an ENERGY STAR qualified unit with a 10-year warranty. The two-stage setup and variable-speed blower motor signal smart engineering for part-load performance.

The 96% AFUE rating means this furnace converts nearly all fuel to heat, compared to 92% on basic models. The 18 SEER1 air conditioner delivers cooling efficiency that matches mid-range units. Two-stage burners and scroll compressor operation at reduced capacity during mild weather extends comfort cycles and cuts energy waste. The 1200 CFM maximum airflow with ECM blower means quiet, modulated operation on most days. R410A refrigerant and standard sweat connections keep maintenance straightforward.

Pros & Cons

Pros

  • 96% AFUE furnace efficiency means 4% more usable heat than standard 92% models, translating to $150-250 annual savings for typical households
  • 18 SEER1 air conditioner exceeds ENERGY STAR minimum, with two-stage cooling that reduces short cycling and humidity swings
  • Variable-speed ECM blower motor runs only as hard as needed, cutting electricity draw compared to fixed-speed alternatives
  • Two-stage burner and compressor provide better part-load operation when full capacity isn't required
  • Plastic PVC exhaust flue reduces installation complexity and cost versus traditional metal ductwork

Cons

  • Specs show conflicting tonnage information, listing both 3 ton and 5 ton with 35,000 BTU cooling capacity, creating confusion at point of purchase
  • 71 dB noise level is audible, particularly during high-speed compressor operation on hot days
  • 10-year warranty requires online registration and may void coverage if units aren't matched properly

Who Should Buy

Best For

Homeowners in HVAC zones 4-7 with existing ductwork and moderate to high heating/cooling demand will see the fastest payback. Contractors upgrading customer systems who value reliable two-stage equipment at accessible price points are the core audience.

Consider Alternatives If

Those seeking premium efficiency above 20 SEER2 or needing minimal noise output should look at higher-tier models with variable-speed compressors and scroll compressor improvements.

Installation

This upflow unit requires vertical ductwork and accommodates both natural gas and propane with proper valve conversion. Electrical runs 115V single-phase 60Hz, needing 21.3 to 35-amp service. PVC exhaust flue simplifies venting compared to metal stacks. A/C lines require 3/8-inch liquid and 7/8-inch suction sizing with 3/4-inch insulation. Standard HVAC techs complete installations in 4-6 hours on replacement jobs.

Warranty & Reliability

The 10-year parts warranty covers manufacturing defects after online registration. Coverage assumes proper installation by licensed contractors and matched equipment configuration. Some components carry manufacturer-specific terms. Registration is mandatory to activate coverage. Most warranty claims process within 2-3 weeks with parts shipped directly.

Frequently Asked Questions

Does this unit qualify for government tax credits or rebates? +
Yes, it carries ENERGY STAR certification and 96% AFUE qualifies for federal tax incentives in some states. Many utilities offer rebates for SEER 18+ and AFUE 96%+ upgrades. Check your local program before purchase. Online Supply lists rebate availability on the product page.
Can I install this myself if I have HVAC experience? +
Installation requires EPA 608 refrigerant certification for the air conditioner side and gas piping licensing varies by jurisdiction. Most warranties void if non-licensed contractors install units. Hire certified technicians to ensure proper setup, charging, and warranty protection.
How much will this save on my energy bills compared to a 13 SEER unit? +
Moving from 13 SEER to 18 SEER cuts cooling costs roughly 28-35%. The 96% AFUE furnace versus 92% saves 4% on heating. Combined savings range $200-400 annually depending on climate, usage patterns, and local utility rates.
What's the difference between SEER and SEER1, and is 18 SEER1 good? +
SEER1 is the newer efficiency rating standard with stricter testing conditions. An 18 SEER1 rating roughly equals a 19-20 SEER on the old scale. This places it solidly in the mid-tier, above baseline 14 SEER but below premium 21+ models.
Is the 10-year warranty comprehensive? +
It covers parts and defects but excludes labor, refrigerant, and damage from improper installation. Warranty requires registration and matched equipment use. Read the full terms before purchase to understand exclusions.
