Review
The Goodman 3-ton horizontal system represents smart value in the mid-market HVAC segment. This combination unit pairs a 60,000 BTU furnace with a matching air conditioning coil, designed specifically for homes where standard upflow installation won't work. Goodman has built its reputation on no-nonsense equipment, and this horizontal variant maintains that straightforward approach while keeping the price accessible for budget-minded buyers and contractors alike.
Heating performance comes from a two-stage burner delivering 60,000 BTU and achieving 96% AFUE, meaning you're converting nearly all fuel to usable heat. Cooling delivers 35,000 BTU through a two-stage scroll compressor using R410A refrigerant with SEER1 rating of 18. The variable-speed ECM blower motor pulls 1,200 CFM maximum, adapting to actual demand rather than running full-blast constantly. These specs translate to real savings compared to single-stage 80 AFUE units, though peak cooling season costs will exceed higher-SEER premium models.
Pros & Cons
Pros
- 96% AFUE furnace efficiency rated among the best in its price category, reducing natural gas or propane bills significantly
- Two-stage compressor and condenser provide better part-load efficiency and quieter operation during mild weather
- Variable-speed ECM blower motor adjusts to demand, improving comfort and reducing electricity consumption compared to single-speed alternatives
- Horizontal configuration perfect for basements, crawlspaces, or attic installations where vertical clearance is limited
- PVC exhaust compatible with modern homes, eliminating costly masonry chimney requirements
Cons
- SEER1 rating of 18 falls below premium systems (20+ SEER2), meaning higher cooling costs in hot climates
- 3.5-ton capacity listed in specs but marketed as 3-ton, creating potential confusion for sizing purposes
- 71 dB noise level moderately loud compared to variable-speed competitors, noticeable during compressor operation
Who Should Buy
Best For
This system suits homeowners upgrading from 80% single-stage furnaces in moderate climates, especially those needing horizontal installation in tight spaces. Contractors looking for reliable, affordable combos for modest-sized homes will appreciate the straightforward design and solid efficiency gains.
Consider Alternatives If
Skip this if you live in very hot climates where high SEER ratings justify premium pricing, or if you need whisper-quiet operation in noise-sensitive settings.
Installation
Horizontal installation requires careful ductwork planning since the unit sits flat, not vertical. The 21-inch height by 26-inch depth footprint fits tight spaces, but technicians must ensure proper refrigerant line routing and slope for return flow. PVC exhaust compatibility simplifies venting, eliminating expensive chimney modifications. Electrical connection runs 208/230V single-phase 60Hz, requiring breaker sizing between 21.3 and 35 amps depending on final configuration.
Warranty & Reliability
Goodman covers this system for 10 years when registered online, a solid middle-ground warranty that protects against defects without matching extended programs some competitors offer. Registration matters here, so make sure to complete it immediately after purchase. This length gives reasonable security for homeowners planning to stay in their homes long-term.
