As a member of Lennox’s Elite Series of furnaces, the G32 is a discontinued mid-level furnace offering up to 94 percent AFUE. According to information from its introduction in 2001, this model features two-stage heating, meaning it was designed to consistently operate on a lower heating level until the system detects a change in the temperature. Benefits of two-stage heating include even heating throughout the home, reduced energy usage and increased temperature regulation, according to the manufacturer.
Additional components of the G32 include a low speed continuous fan operation setting for increased air circulation, an insulated blower motor compartment designed to reduce operation noise, and a two-stage gas valve that quietly adjusts the levels of gas depending on which stage of heating is operating.
Had a 98% efficient Lennox Signature Collection model g32v3-75-5 furnace installed in June 2003. In October 2008, four months after the warranty expired, had to replace an ignitor and fuel valve to the tune of $800. In March, 2009, had to replace a circulator fan module for another $600. Neither the installer, Apollo Heating Inc., Schenectady, NY nor Lennox Customer Service in Dallas, TX, (and the CEO) would respond to inquiries for consideration/extension of warranty coverage. In fact, absolutely no response was received despite sending two letters. Absolutely will NOT recommend a Lennox furnace.
"Water sounds in the Fan"
Water sounds in the fan which caused the g32 unit to quit. I have called Winnipeg Supply for several calls, but they can not find the root cause. So far all I do is spend money on last minute calls when the unit fails. Never buy a Lennox.
Lennox and the G32 receive mixed review around the web. Contractors on hvac-talk.com regard Lennox products as quality equipment, but then note the amount of troubleshooting issues they have with the brand. Several professionals state that they frequently receive service calls for Lennox products and the company isn't proficient at developing the solutions to system issues until after the problem is identified.
These contractors also cite experiencing problems with several components of the G32, including the inducer and roll-outs. These reviewers advise cleaning this unit out frequently to prevent problems, as the piping and internal system are susceptible to accumulating debris and access buildup.
In turn, homeowners on hvac-talk.com post troubleshooting problems with the G32, including trouble with the system wiring and recurring failures and service calls.
The G32 is equipped with a 20-year warranty on the heat exchanger and a 5-year limited parts warranty. Lennox does not require homeowners to register their product to receive the full warranty. Additional coverage must be purchased through a Lennox dealer and must be registered.
