Horizontal A-Coil Flow Direction

[pcasciola]

Does anyone know if the flow direction on a Goodman CHPF horizontal A-coil matters?

I'm not a DIY, just trying to help my installer and save a few bucks by getting my own coil, and have it here and ready to go when he comes in 2-3 weeks to install it. I'm upgrading from an old 7" slab coil to an A-coil, and he wants me to make sure the connections and drain are on the same side as the current slab coil, and to do that I would have to have the air flowing into the point of the A.

One other piece of literature I found recommended a 12" transition between the furnace and the coil if going with the air flow direction I am looking at doing, but that was a different brand. I suppose this is because of the turbulence created by the top of the A-coil being too close to the burner?

Thanks in advance.

Sorry, I meant needing the transition because of the turbulence created by the top of the A-coil, AND the A-coil being too close to the burner.

DO NOT NOT NOT order it off the internet.
Your not helping your installer, in any way shape or form.

If your installer has told you, that you are helping by doing this, then you need to find a different installer.

Your going to lose money on the deal anyways.


That system will not have a warranty. I don't care what the site says. I don't care what your installer says.

Goodman SPECIFICALLY states that anything purchased off the internet voids the warranty.

How's it gonna work, if the installer opens the coil, and there is no nitrogen in it, indicating a leak?

At our company (which we wouldn't be in the situation to begin with), we would suggest we get the new coil, and then charge you for the cost of the coil, uninstalling, and reinstalling the new coil, plus delivery charge.

We would then give you your coil back, to do whatever with. No, we won't talk to whoever you bought it from. It's your coil, not ours.

If you decide to send the coil back to who ever you bought it from, it gets even more expensive. You'd pay the agree'd price, upfront, and then pay for an additional day of labor.

Thanks, that's a good point. The reason he originally asked me to try and find one is because I have a 7" slab coil which he said is not made anymore. He said if I can find one he'd be happy to put it in. He's very reasonable and does good work. He installed a Goodman condenser I bought off eBay last year and the whole job cost me right around half of what several local contractors wanted. It's so hard to find reasonable contractors here in New Jersey, they all think they should be making the same amount as surgeons.

After searching around for hours, I only found one 7" slab coil (by Summit), and I kept seeing these A-coils which look to be much more efficient than a slab coil, and I can get one that matches my current plenum size exactly with the included adapter for about half of local dealer price. The whole thing will cost me less than half of what an authorized Goodman dealer would probably charge me.

Prices are not permitted in post, I removed them.

if you are happy with the mechanic you are hiring to install the equipment... is your insurance company? is the system being inspected? who is to blame if something goes wrong and your house is damaged? what do you think the insurance company would say if something totally unrelated to the installation of the coil but in the area is damaged in your home, and there is no permit or inspection on the installation of this new piece of equipment?
licensed contractors have a LOT of overhead keeping homes from being an insurance nightmare. keep this in mind before you source parts on your own, and have them installed by a qualified tech...

all this said, the answer to your question will have to be answered by the company selling you the coil.

Try running a contracting business for a skilled trade sometime. I can assure you none of us are taking home surgeon pay...

Why shouldn't they? I sure would like to see a surgeon fix his own a/c. :grin2:

It's too bad I can't quote prices these guys charge. I guarantee your jaws would drop. Let's just say the labor charge alone on a 2-day whole house generator someone I know had installed was enough to buy a nice new car.

I will call a Goodman dealer and see what they want to do this job compared to what my local handyman HVAC guy wants. Don't get me wrong, I don't mind paying a little extra for an established business to install it, but double or triple the price, not a chance.

I'm pretty handy and do a lot of things myself including electrical, carpentry, auto work, but HVAC is out of my league. I mean, I'm a computer guy so I installed network controlled Proliphix T-stats in my house and have changed ignitors here and there, but as far as A/C and natural gas, forget it, I'm certain I'd blow something up.

Thats probably because some whole house generators cost as much as new cars. All reletive to the size of course.


As a side note, I wouldn't use the term "goodman authorized dealer" as something of high standing.

Plenty of contractors live in nice houses..
Yet, as a contractor, they do alot of the work themselves, allowing them to have more expensive houses.

The fact that your guy installed a unit off of ebay, is shamefull.

I'm sorry, it is the way it is. I'm sure he's a great guy, but there is no way I would even touch a unit like that.

I do hope you find a reputable company that can install the system to your satisfaction at the price you are willing to pay. keep in mind the future prices on savings, and on call backs/repeat repairs if not done properly, or with the design of your house needs...
price is dependent on customers spending what is asked. if enough customers are present to demand a certain price, it gets paid.

what do you do for a living?

Your're 100% on the money there. The big mortgage scam is when the contractor prices went through the roof here. Everyone was taking equity out of their homes and dumping it right back into their homes, and now the foreclosure rate here is through the roof, and contractor rates are finally starting to come somewhat back to reality since all the fake equity created by the mortgage scam has evaporated.


what do you do for a living?
I'm a computer software developer. I've had my own consulting business for almost 30 years so I know what it's like to be a contractor, but now most of my income comes from full time work since outsourcing drove my rate way down.

I'm sorry, it is the way it is. I'm sure he's a great guy, but there is no way I would even touch a unit like that.He is definitely is a great guy, and has his son helping him so he's teaching him a trade at the same time as making a decent living. I have a lot of respect for the guy, and will continue to hire him and refer him to others. If he can get me the coil I need I would gladly get it through him, but he knows I'm trying to retrofit an old system and is willing to work with me.

I realize Goodman is far from the best, but in this economy I'm lucky to even have air conditioning at all, and this is a 20 year old R22 system so putting in a high end coil would be like bricking an outhouse.

Slab coils are still easy enough to find. As far as goodman equipment, I do not personally deal it, but there is nothing wrong with it. It has gotten a bad rep because goodman distributors have sold goodman equipment for years to just about anyone who wanted it. Then it gets installed poorly and you have all kinds of nightmares out of it. Then the equipment gets blamed instead of the installer. A lot of people hammer Rheem equipment for the same reasons. But here in my neck of the woods, the distributor has always maintained a policy of only selling to licensed qualified contrantors. And as a result, Rheem equipment in our area has a name of being durable, reliable, and effecient. So, whatever you do, just make sure you use someone who will do the job right. It sounds like this guy may be a great guy, just do your homework on him like you are doing on the pricing.
