Carrier Furnace.

I have a carrier Furnace with a faulty heat exchanger. Carrier says they will either replace the secondary exchanger or give $1250.00 towards purchase of another furnace. Has anybody had this done? Can I use the money for a furnace brand of my choice? Waiting for a service tech to verify the problem.
 
Unless your furnace is still under partial warranty, I would assume that discount would be only towards another Carrier unit.

My late uncle used to install for Carrier and swore by them! I have no personal experience with them.

How old is your existing furnace? This is a bad time of year to be getting a furnace, as you can often get a much better deal in the Spring. However, if you have an exchanger that's going bad, might be worth it to have a new unit installed fresh.
 
If the money is cash, take it. Even if you need additional resources to make it happen I don't like Carrier because of their worker displacement after promising to keep jobs in Indy. If the $ are in house, I would replace the exchanger. Jim
 
If the rest of the furnace is close to ten years old or more, I would think twice about repairing it. The same corrosion that took out the first heat exchanger will be throughout the rest of the furnace components too. If the frame has some rust, I would not repair it. Check what kind of a warranty will be on a furnace repaired or replaced under warranty.

Within the next year, try to have a furnace tech look over your furnace installation for what caused the early failure of the heat exchanger: poor moisture drainage; excessive dirt; damp environment; lack of maintenance, etc. The guy who works on your furnace might be willing to check into that too.
 
Trane did the same thing for me a couple years ago. Gave me credit towards a new furnace. I took advantage of it and bought the most expensive new model from trane, even though my in-laws sell and install comfortmaker. Wife didn't care what I did. Glad I did now when it has been so cold, and wife doesn't talk to her brothers now anyway because of estate issues. They main thing is if you like the dealer and they give good service. That is more important then saving a couple hundred bucks.
 
Our Carrier is nine years old and had to have the heat exchanger replaced this fall. Thankfully we have a ten year warranty that covered the total cost. New heat exchanger warranties for only five years. Tech said it was a poor design to begin with. I saw the guts of the old one, nearly rusted shut, looked like an extremely clogged radiator. If they clog completely your CO level goes sky high. With your unit being 18 years old I would replace it. New ones are ultra efficient. Good luck!
 
replace it with a 97% furnace I bought a goodman furnace on line and put it in my self not that big of deal saved thousands look into it before you jump mine was a 60000 btu downdraft cost around 800.00 free shipping 😎
 
The carrier heat exchanger failure was the lining in the secondary would come loose and plug the passageway. If left too long it would rust through. Usually the pressure switch would short cycle. Furnace was designed to have a minimum temp of 60 degrees at the heat exchanger or it would fail. Changed out quite a few not the best because other things would fail and be a bad desision. If it old don?t fix replace. I was oem incorrectly installed would do it also. for five years. Only way it can pass co is if the exchanger was rusted through and that is operator usage and not the heat exchangers warranty.
 
A friend that does HVAC has told me numerous times that when a heat exchanger fails, unless the furnace is fairly new, it is a death sentence for a furnace. He said usually a heat exchanger on a run of the mill furnace is $750+ for a run of the mill furnace. That is HIS dealer cost before it is marked up, and who knows how much that it. Then there is the labor to install, and he says most are not the first thing to come out of the furnace. So he says to replace a heat exchanger that is out of warranty just doesn't make sense unless you do everything yourself, which is *not* recommended

I ran my old Payne for 24 years, finally burnt a hole through heat exchanger and smoked up the house, scared wife bad. New Rheem on order. Natural gas. I only got so many years out of it because we run only a month or so out of 12 in Texas.
Take that credit and put in a new one.
 
Back in 2016 Northern Natural gas shut me off due to old line put in in 1937.They paid me for new{Lennox-top of the line} furnace, new hot water heater, new cook stove, new 1000 gal propane tank w/ fill, line run to house and installation of all plus cash besides. Old furnace and water heater needed to be replaced any way so the timeing was right on. Can sure tell the difference in my electric bill{quite some cheaper}but I do miss my natural gas.
 
WOW ! You hit the lotto ! Wonder why they didn't just rejet the old appliances to work on LP ?
 
I would ask the local Carrier dealer what he could do for you. $1250 towards a new unit seems like the way to go but your dealer may have some insight as to what would be best. Sounds like this unit has some time on it and other things might be on their way out too.
 
On older furnacees with a pilot lite; shut off pilot lite during the summer. It will cause the pipes to rust out.
 
(quoted from post at 11:41:05 01/15/18) Furnace is 18 years old. I,m thinking to replace it not fix.
Agreed.

The heat exchanger at Dad's house went out just about the same time he passed. It was over 21 years old. We were told that this was fairly rare; that most units in that area never went beyond 15-20 years. As the house was sitting vacant, we couldn't justify putting in a whole new unit to just sit there not running, or for some yahoo to come along and steal it.

The plenum in the old system had dripped water to the point where there was a lot of black "growth" in there. It had not spread to other parts of the house and, as it had not been checked whether it was mold or mildew, we just kept our mouthes shut. New owners bought the house (to flip) knowing the heat pump exchanger was bad, and they had new unit with full install.
 
(quoted from post at 15:02:30 01/15/18) They are not going to give him money. they are giving him credit towards a new one.

And that credit will only be applied to the full M.S.R.P.

So shop around and get quotes from whom ever you want to make sure YOU come out ahead.
 
I had this happen on a 25 year old Lennox pulse furnace. The heat exchanger had a lifetime warranty/guarantee. They told me the heat exchangers were getting a little scarce, and I might get a new Lennox pulse furnace instead. Regardless of the outcome, I would have to pay the labor for replacing the heat exchanger or the furnace. They found a new heat exchanger in the parts system. I think it cost me a couple hundred bucks labor. As I recall, this furnace had either an electronic ignition or a hot glow igniter.................I cannot recall as I sold the house 12 years ago after I repaired this. I had trust in the firm whom I was working with, as it was the actual owner who came to service the furnace. He has indicated mine was one of the very first pulse furnaces made by Lennox, and they had proven themselves to be reliable and durable, since there weren't a lot of electronic controls on the unit. In the house I have now, it had a Carrier high efficiency furnace with a hot glow igniter, so there was no pilot light. It was about 21 years old at the time replaced it with a ground source heat pump. I think you have questions that only your furnace technician and supplier can answer. I would suspect if the inner components are in good shape, and not corroded, you should be okay in just replacing the heat exchanger, provided they can obtain one for you. I also suspect Carrier went to this $1250 credit, which would leave the choice of replacement furnace up to you, so you could choose to go with whatever unit you wish to go with, leaving it open to go with a low cost furnace, a value priced furnace, or a premium furnace. Thinking back to my old Lennox, I suspect if the company had to replace my furnace, rather than replacing the heat exchanger, it would have been a lower quality/lower priced unit, rather than a better model.
 
Service tech confirmed that the secondary heat exchanger was bad. Salesman came out with a quote of $4141.00 for a 96.7% 60,000 btu furnace, model# 59TN6. With a buy back of $800.00 for a total of $3381.00. Salesman claims the $1250.00 allowance is bogus. I am getting a quote from a local shop. Would rather spend a little more money with the local guy if need to.
 
That seems pretty high priced to me. When that happened to my Trane, I bought a new 100000 btu for $2400 installed. My new furnace is 97% efficient, and has two stage burner with variable speed fan. I would shop around.
 
Get a new high efficiency unit. Also get a brand new HVAC coil if you have so. Don't mess around with old stuff. My neighbor across the street is Hvac installer and you should so some of the busted up rotten stuff he replaces. Another thing around this time of year ask you installer if the supply warehouse has any year-end models for less. You can save almost 1/2 the price on a unit. Saved almost $800.oo on my unit. I would also tell you with hi efficency units. If the installer says your house should have a 80,000 unit tell him you want the next higher unit. When they are sized correctly it takes for EVER for them to pick the heat back up after a power outage or if the outside temps go really far down. My unit is correct and when the temp was 4? outside the heater ran nonstop for two days. Sort of like just in time manufacturing. Rotten equipment that means. OLD is OLD !! One more thing. When they hook up your little water drain pump for the condensation from the burnners. DON'T run the little hose through the wall. If that little hose freezes you are SOL!. Your furnace will shut down. Take a look at how I redid mine. Took some time, looks like a Steam Punk unit, but she works perfectly. The hose goes through the end of the stack so there is no way it can freeze. Just carefully drill a hole to fit a piece of plastic pipe that will fit the little clear tubing and glue everything together. Feed that tube outside and glue the OUTER elbows on one at a time as you fish the tube through them. I have been told this is the way they do it way up north but I came up with this idea all by myself. You cannot believe how much water that furnace will pump out in just 24 hours. I mean gallons.

Do a search for faulty furnace heat exchanger on the net. I had a Bryant furnace with a bad heat exchanger. I don't remember which furnace company is the one that makes the exchanger for several different other brands. My dealer gave me a good price on a new furnace. This furnace was out of warranty. The replacement route was a lot cheaper than just replacing the exchanger in the old unit.
About a year after the forgoing I was informed about by some legal eagle that I would fall under the class action suit and needed to provide further info on the purchase. Did that and then several months later they requested more info about the furnace and it's purchase. Since I had given them all the information on their first request, I asked them how much I could expect out of the class action suit. They told me about $250 at which point it wasn't worth my time. The deal my dealer gave me was worth more than that. Since you don't have a new furnace from your dealer it might be worth checking out if there was a class action settlement on your furnace.
Long, but I hope it helps.
 
You can use this money to buy any brand furnace of your choice provided it's made by Carrier.
 
we had a carrier furnace where the exchanger went bad also, maybe about 8 yrs ago.i also had my neighbors furnace in basement for parts, traded them both in for a new non carrier furnace, 10 yr exchanger warrentee, cost $800. we did go for one larger furnace too because when the furnace would run, the air wouldnt even feel warm, cold days would run steady. the new one almost runs too hot, as it really gets hot in the bathroom, where the register is next to toilet
 
Glad I didn't buy a Carrier furnace when I built the house in 1978. I have had inspected every other year and still has original heat exchanger and dealer says it in excellent shape. It's a General Electric propane.

I may have given a outdated link but from what I heard Carrier is still standing behind these units.
Your local Carrier dealer should have the effected model numbers.
If he feels his dealer is giving him the run around or short changing him a call to 1 800 carrier will get him straight.
 
Lennox was replacing heat exchangers on early pulse furnaces under warranty. That program expired years ago. I have a Pulse furnace installed in 1992. It has been flawless.
 
Being in the hvac business for 44 years I wouldn?t a Carrier or Trane residential furnace.
 
WGM ...... do any of the manufacturers make their own parts? I suspect they all use components made by someone else right? If that's the case, anybody's furnace is only as good as the parts which make it up. I'm sure there are different grades of the same parts available. I wonder how one brand can be any better than another.
 
I think they are trying to do away with farm customers. I have 4 N. gas lines that run through my farm,wanted them to hook me to one of them,told me it would be too expensive for them to do that.

The regulator(s) to go from 200 to 1500psi in transmission lines to a few inches of water column for one customer are not cheap.
