Efficiency | Goodman Versus Ducane Gas Furnaces

First we’ll begin with the efficiency and gas furnace Energy Star ratings of the units. Efficiency is significant these days, considering that you want to get the best efficiency out of your HVAC system as possible. The higher the AFUE rating for the furnace, the lower your gas bill should be. That saves you money in the long run. Typically, the higher the efficiency, the more the equipment cost; however, this upfront cost is offset by a quicker ROI or return on investment.

That saves energy while saving you every month on your gas bill. Both gas furnaces are Energy Star rated, but in this category for efficiency. Goodman wins coming in at 98% AFUE compared to Ducane’s 96% AFUE.

Blowers and Furnace Staging

Both have ECM variable-speed blower motors so this comparison is the same. That is important for the electrical efficiency of the unit and also some comfort factors. That feature all depends on the control. There are several settings for the Goodman gas furnace and the Ducane gas furnace. It is important before the HVAC installer is finished installing the new furnace that they make sure these settings are correct. Settings are on a circuit board with dip switches.

The staging is important for efficiency also. Goodman comes out ahead in this category with the modulating furnace. While the Ducane furnace is a two stage gas furnace. There is a difference in both the comfort and efficiency of the systems. In the following chart, we demonstrate efficiency and comfort.

As you can see from the graphic above the modulating gas furnace leaves temperatures more even throughout the run time while the single and two stage gas furnaces offer a higher frequency of temperatures. This means if you set the thermostat for 70° F the temperature should stay very close to 70° F while the other types of furnaces will vary out of that range. I would chose the modulating gas furnace for both efficiency and comfort.

Control, Heat Exchangers, and Warranties

Control relates to the thermostat for the consumer. Conventional control means you will have a typical type of thermostat that use many different thermostat wiring colors to attached the thermostat to the gas furnace. These types of thermostats are non-proprietary and can be purchased online or from a hardware store. Ducane mentions nothing about this in their literature, but Goodman does for this furnace.

Goodman refers to it as the ComfortBridge™, and it is proprietary to Goodman and Amana select systems. ComfortBridge is not a thermostat but software inside the controls of the equipment. It is an automated control routine that collects performance data. The data collect allows the internal program to set specific control sequences that aid efficiency but never affect comfort. It works with any thermostat and is independent of any thermostat.

The heat exchangers for these two furnaces are the same. Both the secondary and primary heat exchangers are nearly exact. They both also offer limited lifetime warranties for the heat exchangers, which is the most common big item failure on a gas furnace. Both have similar warranties on the rest of the furnace, which is a 10-year limited warranty. Always make sure you read the warranty and understand it.

Keep in mind, the most common warranty for most manufacturers only include the part and not labor. Labor can be costly, so I would ask if there is an extended labor warranty to match the parts warranty.

Diagnostics and Igniter for Gas Heating

Diagnostics are good for troubleshooting problems with the gas furnace. These types of diagnostic abilities make it easier for the HVAC technician to figure out problems on trouble calls. That has the potential to save you money based on time of repair.

The Silicon Nitride Igniter is durable and will give you long use. It also eliminates pilot lights and lights the burners directly.

Conclusion | Goodman Versus Ducane Gas Furnaces

Overall, from my experience in the field, both bands offer reliability and long use if installed properly and maintained on a regular schedule. Proper furnace maintenance is important not only for safety but also for reliability. Maintenance agreements are always recommended and purchased at the time of furnace purchase. Most maintenance agreements will cover basic maintenance for the gas furnace and an associated air conditioner. The safety factor for gas furnaces is important especially to have the furnace heat exchanger checked on a regular basis.
