Review
The Goodman GMVC961205DN combines a gas furnace and air conditioner into one horizontal unit, solving a real problem for contractors working in confined spaces. This 5-ton system delivers 120,000 BTU heating and 60,000 BTU cooling from a footprint measuring 34.5 inches tall by 24.5 inches wide by 28.75 inches deep. Goodman positions this as an efficient, cost-effective solution for residential retrofits where space constraints make traditional vertical mounting impractical. It carries Energy Star certification, which matters for homeowners pursuing rebates or energy credits.
Performance specs reveal this unit punches above its marketing numbers. The published 15 SEER rating understates actual efficiency, as the condenser achieves 16 SEER1 on the newer testing standard. The furnace reaches 96% AFUE, meaning only 4% of gas energy is wasted up the flue. Two-stage operation on both heating and cooling reduces short-cycling and extends runtime efficiency. The scroll compressor and variable-speed ECM blower modulate output to match real demand, not just cycle on and off like single-stage systems.
Pros & Cons
Pros
- 96% AFUE furnace efficiency recovers heat that competitors waste, cutting gas consumption measurably
- 16 SEER1 cooling rating significantly outperforms the 15 SEER marketing claim, delivering real savings on electricity
- Two-stage burner and two-stage compressor modulate output, reducing runtime and extending component life
- Variable-speed ECM blower motor adjusts airflow from 0 to 2000 CFM, eliminating unnecessary energy use
- Lifetime heat exchanger warranty provides long-term protection against the most expensive failure point
Cons
- Requires licensed HVAC technician for installation, no DIY option, and propane/natural gas safety risks are substantial
- 75 dB noise level runs louder than some premium competitors, notable in quiet residential settings
- Horizontal A-coil configuration limits placement flexibility compared to vertical coil designs
Who Should Buy
Best For
Contractors upgrading older systems in tight spaces, especially basements or attics where horizontal mounting is necessary. Homeowners in moderate climates seeking reliable heating and cooling without premium pricing.
Consider Alternatives If
Anyone uncomfortable with gas appliance installation complexity, renters without landlord approval, or those in extremely hot climates needing single-stage cooling efficiency.
Installation
Installation demands a trained, licensed technician due to gas safety protocols. The unit requires 115V single-phase 60 Hz power with breaker sizing between 37.2 and 60 amps depending on local code. Sweat-type refrigerant connections use 3/8 inch liquid lines and 7/8 inch suction lines. Flue venting requires plastic or PVC exhaust pipe rated for condensing furnace discharge. Horizontal mounting flexibility makes it valuable for basements or attics, but ductwork adaptation may be necessary.
Warranty & Reliability
Coverage includes a lifetime warranty on the heat exchanger, protecting against the costliest failure point, plus 10 years of parts coverage when registered online. This dual approach incentivizes proper registration and provides meaningful protection during the system's productive life. Lifetime heat exchanger coverage is generous for a mid-tier unit, though parts warranties lag behind premium competitors offering 15-year coverage.
