Need new furnance- is this coil compatablie to AC unit

[cking]

I have a 2007 York Affinity 15.5 seer outside AC unit. Need new furnace and have a quote on a Carrier Infinity 80. I was told the coil on the York AC would have to be replaced by Carrier coil CNPHP3612ATA. Will this void the warranty on my AC unit?

What brand, model, eFf, age is the furnace you plan to replace?

I think it's important to have a matching coil and AC condenser.

I would like to know why Carrier dealer recommends the replacement of your evap coil.

If this was my decision, I would probably look at a York furnace to keep everything of same manufacturer.

Do you mind sharing your location?

Post back.

Is the current coil matched to the York? If so, I'd tell that Carrier guy to take a hike. If not, then a new coil should be installed but like Tiger said, should be a York coil. The coil should match the unit, critical with high SEER. If you want another brand of furnace, fine.

no reason they cant use the exsisting coil and make what ever adaptions needed to make it work with the carrier furnace

i agree if you change the coil then it should be matched to the york condenser

My current furnace (the circuit board no longer works) is a 1990 York that is not variable speed. The coil and AC condenser are matched up - in April a new coil put in because originial was defective - York did not place recall on it but took care of it when customers called in due to AC not working. Dealer said coil will not match up with Carrier. Richmond VA

21 year old condenser with a new coil

you wont get to much more life out of the old dog and may be time to replace everthing and save some money on operating cost of the ac unit

maybe you can get a better deal by replacing everything at the same time

[pauls heating &]

it should be adaptable somehow to the new furnace..wether a duct transition.
the coil doesnt know what furnace blows air thru it..
will it be more work than a carrier coil ? perhaps - but a good installer should be able to do it

tin, it's a 4 year old outdoor unit and new coil.

No way should a Carrier dealer throw away a brand new matched coil to sell you his. That is nuts. If he can't keep it, he shouldn't be installing. What a ripoff.

sorry my bad :cheers:


would never sugest replacing the coil in this case. No reason in the world the furnce cant work with this coil even if some transition is needed it can be done and done properly
get a new quote

what size and btu is the old furnace and what size and btu is the proposed furnace .

[beenthere]

Using a Carrier coil will make your A/C a mismatch, and you could end up with a lot lower SEER A/C. Get quotes on a York Affinity furnace.

What is your location?

Here is link to York furnaces.

I would want to try and get a matching system if at all possible.

What's the model number of the coil you have installed now? Was it replaced at the same time as the outdoor unit in 2007?

Thank you for asking this question.

While at first glance I understand most of my colleagues reactions and answers to this question. At second look I have to ask why does this contractor say the coil needs replacing? What are the sizes involved? Is the coil plugged or dirty? Is it too small and causing an airflow question or high static? What visual evidence or test readings does he have to support this? I have often recomended replacing a coil with the furnace if certain conditions exist. If I am installing a new furnace warrrantied through us, then I will test/engineer the airflow. If he is a carrier dealer then in reality I would not always expect him to quote a York coil or furnace. Since our company has recently dumped York products due to numerous warranty issues, we would not probably quote matching York stuff unless you ask either.

The new coil was replaced in April 2011. There are so many number, I think this is the coil number HD48S3XH1H AN1C1864485. The Affinity AC is CZE03611B. Do you need the serial number for the new coil?

I'm just so confused with what to choose. Carrier CVA (80%), York TM8V or TM9V. Everyone gives such a different pitch.

[second opinion]

I would choose the York, the TM8V would use your existing vent style and the TM9V will use two new pipes to the outside

These guys are right. While there are really good reasons to keep your coil if it's matched to the outdoor unit, there is no reason why that same matched coil shouldn't be used other than somoene wants to sell you something so that they can make a little more and potentially save some time on the install. Which works out gret for them if they get away with it.

This is when I would get that Carrier dealer to explain exactly why your coil isn't able to be re-used. If it's anything other than it's a mismatch to the outdoor unit then I would call up either your local Carrier distributor or Carrier corp and talk to someone about it. They can be pretty particular about their dealers and something like this might be of interest to the right people. I can tell you that due to a history poor installations and other issues that there are some former Carrier dealers out there.

If nobody complains then nobody else knows. I always suggest passing on the word when you are either completely satisfied or dissatisfied.

[BaldLoonie]

Looks like an ADP coil.

Still doesn't make sense to throw out a brand new coil and sell a different brand. Unless he can come up with a good reason, I would think it is just easier to slap a new cased coil above his furnace than make this one work.

You can post pictures of the current installation.

I had a couple of companies here that use Carrier products and called Carrier - they agreed with you about using the old coil. When I called the first company back and asked the salesman told me it would be "most" efficient to replace the coil but I could, certainly, use the old one...his reason he was "transitioning" me to Carrier for when that 4 year old York AC gives out.

Doing some checking I wonder about the York TM8V and TM9V which no-one mentioned.

[beenthere]

In other words, he was trying to lock you into them as a customer.

[grasshopper]

If the coil was damaged, plugged dirty or too small for the new furnace's airflow then I might see some reason to replace it. In absence of those reasons, I would tell the Carrier guy to take a hike. I would get some different estimates. Check with someone new perharps. That he would screw up a 4 yr old system to try and lock you in to them for the future failure???? Poor ethics. I would try to gain your loyalty to replace the AC when it fails buy doing the best job possible and then performing great maint/service of bolth appliances in the future to keep them bolth running right until it is time to replace. That 4 yr old could run for 5-10 yrs or more.
