The Goodman GMVC95 furnace is a discontinued series with an AFUE rating of up to 96%. This gas unit was a two-stage, variable-speed furnace designed for for either upflow or horizontal installation, depending on the space available. The unit had an aluminized steel heat exchanger and a stainless steel secondary heat exchanger, and utilized a silicon nitride igniter. The GMVC95 was compatible with other Goodman ComfortNet communicating systems.
As many here know, Goodman says its product must be registered within 60 days to qualify for the 10-year warranty. Canadians should be aware that under Federal Law, such a registration request is illegal. The 10-year warranty must be observed by Goodman Inc. As long as the unit is installed by a qualified installer and maintained accordingly. In voiding the 60 day registration requirement, this law prevents E.G. Goodman Inc. From claiming they “didn’t receive the warranty card” or whatever nonsense they might cook up to get out of the 10-year warranty. Be also aware that this furnace, among other Goodman products, uses a ClimateTalk Alliance open source communication system between the thermostat and the furnace, AC, etc. The thermostats are very expensive, typically starting at $500 US just for the thermostat and more for the installation. Ours broke a few months after the 5-year warranty. Dealer wanted $700 for a new thermostat. Ridiculous. The furnace control board will accept a regular thermostat like a Nest, Honeywell or Ecobee without major modifications or reprogramming the control board if you know what you’re doing. There are lethal voltages on the board so it’s best to install e.g. a cheap $50 thermostat by a technician but mine wanted over $200 to do it. It’s a 15 minute job.
"Way too many repeated problems"
Of the two identical units installed in a duplex, one has ongoing problems of no heat. A flame season they say. About every six weeks it needs service. The other unit works fine. Main circuit board and numerous flame sensor cleanings have created a very untrustworthy experience. What is worse is Goodman customer service. They have blamed me for not asking to have a company service technician work on it. They have blamed me for not registering the units. Check your records Goodman, I did that. They have blamed me for not buying a service contract. They have blamed me for operating it in the vicinity of a clothes dryer…..really? Warranty means nothing to Goodman Mfg. Deflecting and blaming they are good at, listening and keeping the customer happy, not so much. Do not consider this brand. Stay away from Goodman. Spend your money on a more reliable brand.
"Heat exchanger goes bad in 4 years"
The furnace is only four years old and the heat exchanger went bad. The Cu piping was rusted through and created a leak; extremely poor workmanship/design. Material is under warranty but labor and coolant are not; the total bill is $1,250.
"Goodman brand furnace exceeded my expectations"
This furnace has exceeded my expectations. It is very quiet and very efficient. The average gas usage you will save is around 20%. The average kilowatt savings from just the variable speed fan motor is anywhere from 25% to 75% less wattage. When combined with Goodman brands 5″ filter box, this product stays clean and will last a long time. Goodman brand 5″ filters usually need to be replaced once a year and are around $30.
After just 5-6 years of ownership of this heating unit it died, and apparently they have a little caveat in their 10-year warranty that you must register the product, otherwise it is only a 5-year warranty. I didn’t get the impression that the guy on the phone even thought it was a good product, because he started to compare the $10,000 investment in their heating air-conditioning unit to buying shoes that wouldn’t usually last 5 years. In any case, it seems that their product isn’t good and their customer service is worse so avoid buying Goodman.
A homeowner asks the hvac-talk.com forum about choosing between the GMVC95 and the GMVM 96 furnace by Goodman. A professional member recommends the GMVC95 due to better humidity control and better overall value.
A GMVC95 owner writes to justanswer.com that he receives an error message from his control panel each day about a drainage pipe problem. He goes over everything that has been checked by his HVAC technician; the expert online concludes that the homeowner should try a larger PVC drainage pipe, as that is the only thing left that has not been tried.
Another Goodman GMVC95 owner discusses the fact that he wants a different thermostat for his unit on hvac-talk.com. The current thermostat is single-stage, so the owner is not getting the benefits of a two-stage furnace. He plans to install a Goodman air conditioner in the near future, so the online contractors suggest he should check out the ComfortNet system, through which all the HVAC equipment can communicate information such as diagnostics and errors. The owner states that the unit was just installed, so one expert advises that he contact the installing technician for a different thermostat.
Goodman guarantees the heat exchanger with a limited lifetime warranty for the original owner. If the heat exchanger fails within the first 10 years, Goodman will replace the unit. Parts for the GMVC95 are covered by a 10-year limited warranty. Product registration within 60 days of installation is required for maximum warranty coverage.
