This has been quite interesting I mist say. As a Tech, I love it when customers have been doing my job longer than I right @Russ989 😂 Had one today in fact. But in All seriousness…
So being a certified Carrier tech now 23 yrs and have replaced alot of heatexchangers and knowing IDC, they are notorious for not informing customers this option, if your within the 20 year period of that Heatxchanger you qualify for a credit towards a new furnace. Too late now. But Anything 15+ years and the HE goes, I highly recomend the customer to go this route. Hogh eff furnaces typical life span is 20 anyway. The new carier High eff furnaces (around since 12’) have stainless steel heat exchangers and a 10yr parts warranty. Just food for thought.
As for that class action suit. Its a joke IMO. Just another sue happy feak situation. Good for the customer tho. Those HE’rs have been around since 1990 and some still going on the original. Yes there is a small issue that can occur cuz of the acitic moisture that comes from a condensing furnace running through steel and any type of coating will rot over time. LP (Propane for those in Reo Linda) is 10 times more acidic than NG. If u run out of LP in your tank you draw the sulfer out of the bottom and that will do damage to the “Secondary HE” key here, its not the secondary's fault! Will also rot the burners (as shown in the OP’s first post) Looking at those burners, this is what has happend or over time without changing the burners on LP preferably every 3-5 years so you have a more complete burn and a long lasting HE. Gas pressure matters as well but I have not sen it out spec that far often enough to make a difference causing that. Usually its a supply and demand to the home not set up correctly as in adding a Standby Gen (Non certified guys) and it Robbing Peter to pay Paul if you will. Also, the primary HE’s do not need to be replaced unless there cracked and can be kicked back by carrier in some cases if there not cracked.
Fyi if your all still with me here, @Russ989 knows this, all band High eff furnace HE’s can fail the same way without proper yearly maintenance. Check GP, Burners, keeping the internal moisture trap of the furnace clear and above all no screens or restrictions at the venting intake and exhaust. Those restrictions will change the fuel air mixture and therefore failed HE’rs I see it every year. Also a Pressure switch will only shut a system down if there is a restriction or the inducer assembly (draft motor) isnt pulling enough. The only PS that will shut a furn down for GP is the one at the GV (gas valve) supplied with an LP conversion kit if the pressure at the “TANK” drops, not at the burners! that PS is located at the inlet of the GV. Not outlet. Little tip, they fail/dont work 1/2 the time.
That tech was using a Combustion analyzer BTW. They are nice but complex and for certain applications but not necessary in many. Alot of younger techs are using them on EVERYTHING Thats a single stage furnace, a simple manometer would have been fine to set that up. 15-20 min max and out.
Thats the end of our lesson, there will be a quiz at 0700 tomorrow! 🥳
