Heil Heat exchanger gone bad. What to do?


Thanks for the replies. Here are my current options:

1. Repair HX: $600 parts and labor (absolute cheapest route, I order the part and craigslist guy does the install)
2. Replaced by licensed Craigslist guy: $3200 (Goodman 2.5 Ton Gas Pack)
3. Replaced by lesser known but legit company in Charlotte: $5169 (Trane 2.5 Ton Gas Pack after $1500 govt. tax credit and $200 local power company rebate)
4. Replaced by largest and most reputable company in Charlotte: $6830 (York 2.5 Ton Gas Pack)


What do you guys suggest?

If the Trane qualifies for the tax credit, and the other ones don't.
You aren't comparing apples to apples.

You should get quotes on equipment that are in the same line and SEER to each other.

Heil Heat exchanger gone bad. What to do?


Thanks, I wish I had time to research this more and make it apples to apples, but unfortunately, I don't (and I can barely type this as it's 41F in this room right now). I had them all come tonight, and of course, they all showed up at about the same time. So it was a little hectic and I didn't get all of the numbers. What makes this even more difficult is guessing whether or not a unit qualifies for the tax credit. None of the estimators could give me a straight answer or made me confident that their unit would qualify except for option #3. I don't guess this is the first time govt. has made things complicated.

BTW, company #3 gave me a detailed printout and the model number on the Trane would be 4YCY4030A1075A.

Yeah. The Trane meets the tax credit requirements.
need model numbers of the others to know if they do or not.
If they hee hawed around it. They are probably quoting units that don't.

You should repair if the chance of the repair holding for a reasonable amount of time is at least 100($600/$3200) = 19%.
I don't think, at 11 years, you are experiencing the increasing failure rate of the parts that is expected of normal wearout. I think you are still in the random failure phase of equipment lifetime, but the HVAC guys know the quirks of individual makes and models.

Very good information. I believe you've changed my mind, think I may just repair instead...

My licensed craigslist guy has found a HX in stock in Charlotte for $397.30. Labor $250. Can install tomorrow morning. This is the route I'm planning on taking, I'll keep you guys posted.

So at 11 years. You have already gotten more then 50% of expected life span from that unit.
Better off replacing.
And having a warranty on all parts again. In stead of having to pay for more parts in a year or 2.
What he said.

Being out doors the gas pack gets beat to death.

Well, the ship has already set sail, so we'll see in a few years if anything else goes bad. Don't be surprised to see me post an update in 2 years (or heck, this summer) with me asking for suggestions on a new compressor

Yep.
Might end up with spending $3,900.00 bucks over 3 years to keep that unit going.

After all. it has passed the 2/3 ways of its expected life span.

Especially in a humid climate. Circuit boards, fan motors etc are exposed to the moisture, corrode faster etc than an indoor unit.

In any case, have 3 CO detectors in your house. Try to get the kind that are more sensitive, that detect below 70 PPM.

I think the unit should definitely be replaced but due to the weather and your financial situation maybe spending 6oo is not a bad idea.

But I would just use the new heat X as a temporary unit and be looking to replace in the upcoming months.

What I would do is homework find out all the information you can on what units are out there, prices, efficiency, Companies, rebates, ETC and start over on getting prices.

Take the 600 as well spent getting you through the winter then get a new system.

Right now is not the time to be getting quotes on new systems, Ok OK lighten up all you businessmen.

I just can't imagine it being all that cold in NC.
that 2 or 3 space heaters wouldn't hold him over until he could choose a good company to replace the unit,
