ACE HI PLUMBING, HEATING, & AIR – GOODMAN FURNACES

There are eleven types of furnaces that Goodman produces, The company separates these into a ‘standard-efficiency’ class and a ‘high-efficiency’ class. Efficiency is measured in AFUE (annual fuel utilization efficiency), which reflects the percentage of heating energy that reflects the percentage of heating energy that gets converted to thermal energy for a house.

Most Goodman’s furnaces use heated aluminum coils. Some of theses have secondary heat exchanges made from stainless steel. All of the Goodman’s furnaces are gray and have highly durable finishes to protect their exterior.

STANDARD EFFICIENCY FURNACES

All of Goodman’s standard furnace models list AFUE of up to 80% and the standard efficiency models include GHS8,GME8, GMH8, GMS8, and GMVC8. There are several features distributed among these models, in various combinations.

MULTI-SPEED heaters can save on energy because they can operate at various different levels. This depends on the amount of work that needs to be done.  Goodman’s multi-speed heaters have four different operations.

VARIABLE SPEED furnaces operate according to a similar principle. Instead of providing discrete options, they have the capacity to vary their speed across a continuous range.

MULTI-POSITION furnaces can be installed in different positions that may be useful to homeowners who need to fit a furnace into an unconventional location.

SILICON NITRIDE IGNITERS are electric igniters that can increase energy efficiency because they don’t require gas.

COMFORNET COMPATIBILITY

Some of the furnaces are compatible with Goodman’s ComfortNet, which is a system that monitors temperatures in order to create rapid and efficient responses from the heating system. This includes a thermostat display and can be connected with four wires to the main unit.

Goodman’s High Efficiency models include GMVC95, GCV95/9, GMH95, GCH95/9, and GKS9. These range in efficiency from 92% AFUE to 95% AFUE. Some efficiency is due to more sensitive control over the heating function and some is due to better insulation. Many have the same combinations of features as above are available.

There are two stages that some of the efficient furnaces have, meaning that in addition to operating at multiple or variable speeds, they engage a separate component for heavy-duty heating. This process is relatively energy efficient. Two of these models, GCV95 and GCH95 are downflow furnaces, meaning that cool air enters at the top and is heated by rising warmth from the bottom. Since the heat is going to rise anyway, this makes for an efficient model.

The “top model” of these furnaces is the GMV95, which has a 95% AFUE, variable speed, and two stages. It has an electronic control board that allows individualized control over its various elements.

CARE AND MAINTENANCE

Goodman recommends that homeowners work with a professional contractor for maintenance purposes and that they schedule tune-ups for their central air system annually.

WARRANTIES

Most models come with a ten-year limited warranty for their parts. Top models also come with lifetime warranties on their heat exchangers. Through the GoodCare program, you can purchase additional maintenance.
