trane vs goodman vs rheem

______________________________________________________________________ give a TRANE, GOODMAN and a RHEEM which one is the worst performer. Also, which one will I have difficulty finding parts to maintain. Patrick B. Powe SR Replies: mastertech “Re(1):trane vs goodman vs rheem” , posted Wed 30 Nov 19:17: ______________________________________________________________________ Goodman worst preformer. Trane the best. Rheem is a good unit. As for HSI or spark ignitors i love HSI cant stand spark ignitors and probably never will. Reason why is some times they work and some times they dont, but HSI main flaw is they are extremely brittle and can break if touched(which u should never have to touch). Basicly ive seen many spark ignitors fail when sparking through gas but have never seen a HSI fail to light when glowing and gas turned on. Then all the clicking lol. As for parts there all about the same. Goodman parts cheapest and Trane & Rheem basicly the same price. Most top brands will cost about the same to fix excempt for Lennox which will cost more. I too have Trane in my house XLi 19 heat pump.

Only the secondary heat exchanger is stainless in a Trane. Goodman uses alumized-steel for both of their heat exchangers. Why is stainless better? because the heat exchanger does get condensation in it and with condensation you get rust. It could be compared to a car exhaust, the cheaper cars have aluminized-steel exhaust pipes The more expensive cars come with stainless exhaust. I have a 94 caddilac with stainless exhaust, I finally had to replace the exhaust last year. Rheem Has direct spark ignition. They use to have hot surface until they figured out it was not as dependable. Trane and Goodman do not. Rheem has a good solid cabinet with rubber sealed panels, held on by heavy steal screws to keep the panels sealed tight. Rheem is a very quiet running furnace. Rheem is the only manufacturer that makes a variable gase valve. In my area I can get parts for Rheem furnaces 24Hrs a day. To answer your question I would say Goodman is the worst. Rheem and Trane are the top 2 furnaces made today.

I am sure it was a honest over sight on Tom’s part.Also if you follow this link you will see that Goodman DOES use stainless on the secondary exchanger.http://pages.zdnet.com/vandykr/id1.html I am positive its a honest mistake on Tom’s part. Yes! I CAN fix that! Tom R “Re(3):trane vs goodman vs rheem” , posted Wed 30 Nov 22:47 ______________________________________________________________________ I did make a mistake, the Goodman’s secondary heat exchanger is stainless. As far as aluminized steal having a better transfer of heat, I would like to see the proof, since Rheem’s top of the line furnace is more efficient then Goodman’s top. It just doesn’t make any sense if they are getting 30% more heat out of the heat exchanger. Also, if you think about it, that would mean a furnace with a aluminized heat exchanger would be smaller then a Rheem since the exchanger would be smaller. Not the case, Rheem makes one of the smallest furnaces at only 35″ tall. I’m sure this was also an honest mistake by Ace.

I am sure it w … ______________________________________________________________________ So what you are saying is that a 90% furnace with a stainless heat exchange puts out 90% if the input btu, but one with an aluminized heat exchanger puts out 120% of the input btus. Hmm. care to explain that for me? acefurnacefixer “Re(4):trane vs goodman vs rheem” , posted Thu 1 Dec 06:53 ______________________________________________________________________ Heat transfer folks………….In other words the heat exchanger on a furnace with a aluminized heat exchanger can be up to 30% hotter then a stainless steel heat exchanger……withthe same amount of gas flowing through it. Tom, I have to correct you you stated “Goodman uses alumized-steel for both of their heat exchangers” if you follow the link I posted it the previous post, You will clearly see that you was wrong……have a great day my union brother! Yes! I CAN fix that! Tom R “Re(5):trane vs goodman vs rheem” , posted Fri 2 Dec 07:51 ______________________________________________________________________ Where’s the proof? If you compare the furnaces it just doesn’t ad up. Aluminum, itself is a better transfer of heat then stainless steel but we are talking about ALUMINIZED STEEL which has very lttle aluminum in it. “aluminized heat exchanger can be up to 30% hotter then a stainless steel heat exchanger……withthe same amount of gas flowing through it.” Why aren’t the aluminized heat exchangers smaller then? Something you need to think about. Tom acefurnacefixer “Re(6):trane vs goodman vs rheem” , posted Fri 2 Dec 16:23 ______________________________________________________________________ “Why aren’t the aluminized heat exchangers smaller then? Something you need to think about.” Tom, this requires very little thought…..the larger the surface of the heat exchanger, the larger the surface for the blower air to make contact. Tom I really have to ask this question……….are you a service tech, or a tin knocker?You dont seem to know much about the technical side of the trade, just what you read in a bias brochure. Yes! I CAN fix that! Tom R “Re(7):trane vs goodman vs rheem” , posted Fri 2 Dec 21:31: ______________________________________________________________________ “this requires very little thought…..the larger the surface of the heat exchanger, the larger the surface for the blower air to make contact.” Exactly my point! Eveyone else seems to get it but you. “Tom I really have to ask this question……….are you a service tech, or a tin knocker?” I have been a Union sheet metal worker in Cleveland Ohio for 17 years now. I have worked in all of the hospitals in the greater Cleveland area and ran a lot of those jobs installing the duct systems. Four years ago, I decided to start my own residential company since so many people wanted me to help them out and do work on their residential equipment. I also received my license at that time. I learned most of what I know from hands on experience and applying common sense. It really doesn’t take a rocket scientist to figure out why a furnace isn’t working. This past summer I had to go to Atlas Steel to replace a dust collector and duct that had been destroyed by an explosion. The explosion was caused by a spark in the duct with the right aluminum/air combination being met. This compnay makes the tubing for the heat exchangers. I seen the aliminized tubing that is used for the heat exchangers and how they are made. The steel tubing is basicaly coated with aluminum to slow down the corrosion process. They look just like exhaust pipes you use on a car. What I am getting at is, the pipes are still mostly steel with just a coating of aluminum. I hope this helps you understand. By the way what are your cradentials Ace? How many years was your aprenticeship? Do you hold an HVAC license?

He first said, aluminized is a better transfer of heat. That would mean a aluminized heat exchanger that is 30% smaller then a stainless would put out the same heat(WOW). Shank, you noticed something I didn’t. He then goes to say that you can get 30% more heat out of a btu with the aluminized. You can look at it like you did, and ask how can you get more heat then the actual flame it self or ask why furnaces with stainless heat exchangers aren’t rated at 70% or lower efficient. Tom shank “Re(5):trane vs goodman vs rheem” , posted Thu 1 Dec 10:56 ______________________________________________________________________ Well for whatever reason I’ll talk the stainless with lifetime warranty. And if personal comfort is you goal get the Rheem Modulating 90 hvac_dude “Re(1):trane vs goodman vs rheem” , posted Wed 30 Nov 17:07 ______________________________________________________________________ All depends on what you want to pay and how professional the installation is… I have a GOODMAN in my house, installed by me, I replaced an 18 year old TRANE…
