Luxaire G9T Furnace Reviews

"Absolute junk, won’t take if given out free"

1.0 rating
Very Unsatisfied

Had to replace a board on the furnace, to save couple of box, the manufacturer has re-designed the board to make it fit to different models. The replacement kit wouldn’t fit at all, had to customize it. A job that normally takes 30 minutes, took me 2 hours, and after the start the board was giving error flash code that wouldn’t make any sense at all, don’t buy luxaire, don’t take it if given out for free, you end up paying more on fixing it.

I am not a customer. I am a dealer. I want to say I’m sorry for all these people that are not satisfied. It is the Dealer not the Furnace. We give free 10 year parts warrranty on all parts. Modules and everythng. All we have to do to get this for our Customers is to go on line and register. There is no cost to us or you the consumer. Our Labor is 1 year. Our customers love Luxaire and that is alll we sell. We have been in business here in New York for over 50 years and have wonderful customers. Again, find a reputuable dealer, there are some scammers out there. They install them and walk away. If your dealer is any kind of a good person he will stand by you and make sure they warranty their products. By reading all these comments, it sounds like the techs aren’t trained properly. That’s not your furnaces fault.It could also be that your tech is getting free parts and charging you for them. But their warranty is great!!!

I have a Luxaire (G9T10014UPC13C) that ran okay for about six years and since then had a series of problems. One of the top companies in Chicago services it. Heat still keeps going off.

"Lois in Pickerington, Ohio"

1.0 rating
Very Unsatisfied

This unit went through 3 inducer motors. The first went after two years, replaced with one that went out in 2 weeks and the third went after 6 more years. I got a total of 12 years out of this furnace. The inducer motor was made by Fasco and was a Swirlwind. I located Fasco and was told that Luxaire was putting in the wrong type of inducers in this model furnace. I tore down the inducer and saw that the bearing were worn out, causing the turbine fan fins to hit on the inside of the motor housing. I think Fasco was lying and since these motors are made in Mexico, what can you expect. I bought a Carrier. Better, longer warranty.

"Looking for an Upper Heat Exchange unit"

5.0 rating
Very Satisfied

While we have never had a problem with our g9t unit and we have been very satisfied with its performance, at 11 years old we are in need of a new Upper Heat Exchange Unit. Our local Luxaire authorized repair center placed the order 12/10/2009 and still have not received the part. They tell me the part is still on order to be received in the USA and that Luxaire has no current inventory of this part anywhere. Living in PA, it has been a very cold 4 weeks and I would really love to find this part asap. Can anyone tell me where I might find this part? Pls email me at [email protected]
