Goodman Gas Furnace Review

The Goodman line of gas furnaces is a well-established brand in the HVAC market segment. Goodman gas furnaces are a fixture in many homes because they offer high-efficiency gas furnaces at a price that will not break your budget. In this article our review will focus on the energy efficiencies, brand models, features, purchasing cost, warranty, and installation of the Goodman brand of gas furnaces. The Goodman brand emphasizes affordability without compromising quality and engineers their products with a no-fuss approach that avoids add-ons to their gas furnaces that would hike the price point with only marginal gains in usability. This approach is advantageous not only regarding cost but also in that the gas furnace still functions as it’s supposed to, but fewer components limit the number of failure points of the furnace.

Goodman Gas Furnaces Heat Efficiency

GoodmanFurnaceOne of the standards of measuring the efficiency of a gas furnace is the Annual Fuel Utilization Efficiency, abbreviated as AFUE. It is a measure of how efficiently the gas furnace converts gas fuel, be it, natural gas or propane into heat. The higher the AFUE percentage, the more heat you get per unit of fuel consumed.

The Goodman line of gas furnaces offers two categories of products when it comes to heat efficiency. One line has an 80% AFUE rating, and another line has a 90% plus AFUE efficiency. The models that have an 80% AFUE specification are:
  • GMVC8 - Two-stage, variable speed
  • GCVC8 - Two-stage, variable speed
  • GME8 - Two-stage, variable speed
  • GMH8/GDH8 - Two-stage, variable speed
  • GMS8 - Single-stage, variable speed
  • GHS8 - Single-stage, variable speed
  • GDS8 - Single-stage, variable speed
These gas furnaces are specified as either single-stage or two-stage. Let's look at these terms briefly.
  • Single-Stage Gas Furnaces

A single-stage gas furnace has a gas valve which you can only set to either on or off and a fixed speed hot air blowing motor which blows the heated air at a set speed when turned on. A single stage gas furnace operates at full capacity when on and cannot be adjusted to suit the harshness or mildness of the weather.
  • Two-Stage Gas Furnaces

This type of gas furnace has a gas valve with a variable setting of high and low. The hot air blowing motor also has a variable speed that determines how much hot air is pushed through the system. These two features allow you to adjust the output of the furnace depending on the harshness or mildness of the weather.
  • Advantages

    • They only consume as much fuel as is required, allowing you to save on fuel costs.
    • They produce less noise because the motor has a variable speed controller.
    • They can run continuously with fewer starts and stops
Now that we have taken a look at the furnaces with an 80% AFUE, let’s review Goodman’s large selection of higher efficiency gas furnaces, listed below:
  • GMVM97 - 98% AFUE
  • GCVM97 - 97% AFUE
  • GMVC96 - 96% AFUE
  • GMEC96 - 96% AFUE
  • GCEC96 - 96% AFUE
  • GMSS96 - 96% AFUE
  • GCSS96 - 96% AFUE
  • GMSS92 - 92% AFUE
  • GCSS92 - 92% AFUE
This line of gas furnaces incorporates models with self-calibrating gas valves that control the amount of gas fuel used with higher precision. The variable speed motors are also more finely tuned which reduces the noise output of these furnaces and distributes the heated air within the home more efficiently. This higher efficiency means lower utility bills for you.
  • Cost Versus Value

A comparative cost of the top 10 best gas furnaces reveals that Goodman offers the best value for your dollar. The Goodman line doesn’t add extra parts or unnecessary components which allows them to be competitive on price, product options warranty, efficiency, and low installation and maintenance costs
  • Installation

The higher AFUE rated gas furnaces have the option of multi-position installation. This means that they can be installed in a position that works with the space that you have available.
  • Warranty

Goodman offers a lifetime warranty on any heat exchanger, the most expensive part of a gas furnace, throughout their entire line. Consumers are advised to register the products within 60 days of purchase to take advantage of this lifetime warranty and ensure peace of mind.
  • Other Features

As if the furnace itself and the outstanding warranty weren’t already an excellent deal, Goodman gas furnaces also come with the option of dehumidification, and Comfort net which is a remote way of accessing your gas furnace over the internet.
