Types of Goodman Furnaces

‍

Single-Stage Furnaces

• One heat output: ON (full blast) or OFF
• Lower upfront cost
• Best for mild climates (like Arizona winters)

Two-Stage Furnaces

• Two heat levels: low (normal) + high (very cold days)
• More comfort and efficiency
• Quieter operation

Modulating Furnaces (Premium)

• Adjust heat output in small increments
• Best comfort + most efficient
• Rarely needed in warmer climates but top-tier performance

‍

Efficiency (AFUE Ratings)

AFUE = Annual Fuel Utilization Efficiency

• 80% AFUE → Standard efficiency (common in AZ)
• 90–98% AFUE → High efficiency (more common in colder states)

Example:90% AFUE = 90% of gas turns into heat, 10% lost

Pros of Goodman Furnaces

• Affordable upfront cost
• Easy to service & widely available parts
• Lifetime heat exchanger warranty (on many models)
• Good availability for quick installs/replacements

Cons to Consider

• Not as “premium-feeling” as brands like Trane or Lennox
• Efficiency options are good, but most installs in AZ stay at 80%
• Performance heavily depends on installation quality

‍

Real talk:

A properly installed Goodman often outperforms a poorly installed “high-end” unit.
