// Bottom Line
This Goodman system is ideal for homeowners seeking balanced heating and cooling efficiency without premium pricing. The 96% AFUE furnace paired with an 18 SEER2 condenser makes it a solid mid-to-upper tier choice for cold climates where heating dominates seasonal costs.

Review

The Goodman CAPT4961C4 positions itself as a mainstream efficiency choice for homeowners balancing performance and cost. This split system pairs a gas furnace with an air conditioner condenser, both featuring two-stage operation. Weighing 73 pounds and occupying compact dimensions of 30 by 21 by 21 inches, it fits standard equipment pads. The system carries Energy Star certification, signaling above-code efficiency without reaching premium-tier pricing.

The furnace delivers 100,000 BTU heating output at 96% AFUE using two-stage burners, significantly better than baseline 80% models common in older homes. Cooling capacity reaches 47,000 BTU with an 18 SEER2 rating from the scroll compressor and two-stage condenser. The variable-speed ECM blower motor adjusts to 2,000 CFM maximum, reducing runtime and electricity costs. Operating noise measures 72 dB, comparable to window units but noticeable during peak cooling.

Pros & Cons

Pros

  • 96% AFUE furnace efficiency significantly reduces natural gas or propane consumption compared to older 80-85% models
  • 18 SEER2 condenser rating delivers strong cooling efficiency, earning Energy Star certification
  • Two-stage operation on both furnace and compressor reduces short-cycling and improves comfort consistency
  • Variable-speed ECM blower motor fine-tunes airflow and reduces electricity waste
  • PVC exhaust compatibility simplifies venting in modern homes without masonry chimneys
  • 10-year warranty with online registration provides solid coverage at this price point

Cons

  • Spec sheet lists conflicting tonnage: 4-ton in title but 5-ton in specs, creating confusion for proper system matching
  • 72 dB noise level ranks as moderately loud for outdoor condenser operation near bedrooms or living spaces
  • Two-stage heating and cooling, while efficient, doesn't match the comfort ceiling of variable-capacity inverter models

Who Should Buy

Best For

Homeowners in northern climates replacing old furnaces want measurable heating cost reductions from the 96% AFUE rating. Contractors installing split systems in existing homes appreciate the straightforward upflow configuration and PVC venting compatibility.

Consider Alternatives If

Budget shoppers seeking absolute lowest price should explore 14-16 SEER2 units, and homeowners in variable-load climates may prefer variable-capacity systems for maximum efficiency.

Installation

This system requires standard split installation with refrigerant lines, electrical service between 29.3 and 50 amps at 115V single-phase, and PVC exhaust piping for the furnace. The upflow orientation suits basements or utility closets. Liquid and suction lines measure 3/8 and 7/8 inches respectively with sweat connections. Most HVAC contractors complete installation in one day assuming existing ductwork is compatible.

Warranty & Reliability

Goodman provides a 10-year parts warranty activated through online registration. This covers compressor, heat exchanger, and major components but typically excludes labor and refrigerant. Activation requires proof of professional installation and serial number registration within 60 days of purchase.

Frequently Asked Questions

Does this system qualify for utility rebates? +
The 96% AFUE furnace and 18 SEER2 condenser often trigger utility company rebates in cold climates. Check local provider programs, which typically cover 10-30% of equipment cost. Many states also offer tax credits for systems meeting Energy Star standards.
Can I use existing ductwork and furnace pad with this unit? +
Yes, if your current pad fits 30x21x21 inches and ductwork accommodates upflow airflow. The 2,000 CFM maximum blower requires properly sized ducts to avoid noise and efficiency loss. Have a contractor measure static pressure and duct cross-section.
How much will heating costs drop compared to an old 80% furnace? +
A 96% AFUE furnace wastes only 4% of fuel versus 20% for 80% models. On a 100,000 BTU system, expect 15-20% annual gas bill reduction depending on climate and usage. Actual savings vary by local gas rates and winter severity.
Is 18 SEER2 better than 16 SEER2 systems from competitors? +
Yes, marginally. An 18 SEER2 unit delivers roughly 12% better cooling efficiency than 16 SEER2. Over 15 years, this translates to $400-600 electricity savings in moderate climates. The upgrade cost typically exceeds long-term savings for mild climates.
What does the 10-year warranty cover and exclude? +
Parts coverage includes compressor, heat exchanger, and sealed components. Excludes labor, refrigerant, ductwork, and damage from improper maintenance. Requires online registration within 60 days and professional installation by licensed contractors.
