Question Heat exchangers

I have a seven-year-old Rudd gas pack. The HVAC technician is inspecting and servicing it at the moment. He just told me that the heat exchanger has some small cracks. Always the skeptic, I took a close look at the cracks and pressed hard on one of the pipes -- and yep, there's a couple of small, rusty cracks about an inch long on the exchanger pipes. He said that cracks in a heat exchanger could cause carbon monoxide to enter the house, but that's it up to me as to whether I want to replace it. In any case I'll have to sign the statement saying that I was notified of the cracks. He's going to look up the price for a new heat exchanger and says it could take two or three weeks to get the replacement. His company specializes in Carrier equipment. Luckily it's summertime so I can still use the airconditioning.

What do you think? Should I have the heat exchanger replaced or would I be over-reacting? I'd bet that half the heat exchangers in this town are cracked and the homeowners don't even know it.

And does anyone know about how much a Rudd gas pack heat exchanger should cost (roughly) ?

Thanks in advance for advice, comments, suggestions and opinions.

Not sure what the cost might be. Being only 7 years old it should be under warranty and you'll pay labor.

If I were the tech it would be red tagged and the gas shut off. Don't take the chance.

Package units are know to have a lot of heat exchanger rusting due to design lay out.

As Matt said, it may be under warranity, check your papers.

It's a gas pack (air-conditioning and gas furnace combined). Is it okay to continue using the air-conditioning this summer until they get a new heat exchanger? It wouldn't seem like the air-conditioning part would have anything to do with the heat exchanger.

Thanks in advance for info.

Heat Exchanger

It is fine to run the system for cooling but not heating.
I too would think the heat exchanger would be under warranty.

The contractor told me this morning that the total cost of installing a new heat exchanger will be $612.00. He said there's three years of warranty remaining on the old one. I guess I'll tell him to do it. It's an old (since 1952) and reputable local company, good testimonials, member of Better Business Bureau, etc. etc.

The technicians that came yesterday to do the routine service and inspection seemed to be highly experienced, very knowledgeable and had answers to all my questions.

But $612.00? Yikes!

That's a decent price. Some of those can be a pain in the butt to change out.

I agree, that is a very good price for a change out.. As Matt said, they are a pain to change out, and take some time to do.

Make that three

I too agree the $612 is quite reasonable. Once in a great while you'll run into one that comes out & goes in easily but most of the time screws & bolts are rusted. Some wring off, some strip, some are just a pain to get out.
