First off, I am a woman with very little knowledge in search of some answers to how HVAC systems should work. I've been reading some of the posts and some of the abreviations I don't get so if someone can "spell it out" for me that would be GREATLY appreciated.
I had a Carrier 48JZ unit installed on Jan 3, 2003. I've had it serviced faithfully 2 times a year.
I am now told that the combustion motor is shot (I saw the blades were rusted right off today) and the heat exchanger needs to be replaced due to rust as well. The GOOD thing is the heat exchanger is still covered under the 10 year warranty (labor is extra - a lot), but the combustion chamber is not.
I asked my tech was there ANYTHING that I could have done to prevent this from happening - NO, he said. He advised me that the combustion motors are a common problem with my model and in fact, the part is on back-order.
He further commented the high humidity of our NC weather contributes to the rust.
My question is... if this normal "wear & tear" or is this just an inferior product and ill-suited to the highly humid area where I live?
I mean if rust is a potential/probable issue WHY would someone recommend a unit that is going to rust and need a repair in 5-6 yrs that about 1/2 the cost of the original unit??
Shouldn't a "professional" recommend a unit that will hold up to the weather conditions? Or should I just expect/plan on replacing expensive parts every 5-6 yrs?
I need someone I can trust and honest advice.
Is it worth me calling Carrier to complain? (nicely of course) Because if the tech sees this problem "all the time" why has Carrier not addressed this?
Again, I do NOT know what the life of a combustion motor should be. But my gosh, it seems that it should last at least 10 yrs.
My last hvac unit lasted 12 yrs. I forget what kind it was, but it was faithful until the end...
