Been reading for hours and hours on this site. Great information, but I still have questions. I'm looking to replace my AC/Oil heat system with up to date equipment. I had two quotes one for the Infinity 24ANA1, and the IQ drive by Frigidaire (no model specified). Both did manual "J" and came to same conclusion - four ton and variable speed furnace fan. I tried to get a third estimate but never got a call back even after a second call. Actually three people never got back. I'm sure they must be very busy.
In addition to the current system being 20 years old, I have high humidity. Previous advice to let system cycle with fan on auto has helped somewhat but still high. Both quoted units look to be a possible answer to my humidity. From what I've read the IQ drive looks the most appealing but I'm still not sure I know all the facts about both units.
Any input about these two units would be appreciated.

The Infinity should alittle more beacause you r getting alot more than Frigidaire. 2 stage, communicating, micro tube, 21 seer, quiet, all metal with rock gaurd, back seating valves, forward swept blades.

The Infinity should a little more because your getting a lot more than Frigidaire.
Wrong there Bro IMO, there is no "Condenser" period on the market today that even comes
close to the IQ Drive Maytag or Frigidaire, and in 2009 Nordyne is stepping up to the plate
with something that will make the Infinity system look like a lego system. :D

Thats right in 2009, He is talking about today, this year, maytag asked me to sell their equipment and told me I would have to drop Carrier, I told them make a Decent quiet unit and get competive and maybe we will talk. Didn't maytag buy the name off miller or am I mistaking. I think Carrier has stepped up to the plate more time with 1 product than maytag has in the existence of all products.

Does that plate stepping include that wonderful Millenium Compressor technology?
They hit a home run with that one didn't they? :eek:
I cannot comment on the IQ system as I have not seen one run. But I will tell you that I have been in the biz for 11yrs and when I installed a new system last year I had the pick of the roost and could have installed any forced air system on the market, I choose a Carrier Infinity Dual Fuel system. Absolutly love it. By the way I work for a Trane Dealer.

Never heard of such a crock, we have sold Maytag and Carrier for the past 7 years together. I have not sold any 23.0 S.E.E.R. IQ drives , but have seen some run in Fort Worth area,they are very quiet and keep steady no matter how hot it gets outside! 105*+
As far as Carrier Infinity systems we have sold more than 100 complete , designed systems last year,with less than 1% call-back rate.
The INFINITY is hard to beat, and savings in our area are running from 45/53%.

Jack2007,
As you probably know the IQ is an inverter drive system and is a copy of the inverter systems used by many Asian manufacturer for decades. In fact, the compressor is made by Panasonic. Inverter technology is what the the rest of world has been using for some time now as they have much higher energy cost then we do here in the US.
If you are really interested in this type of system, as it is the top of the heap for top comfort systems, check out the systems by Daikin VRV-S, Sanyo Eco-i Mini, and Mitsubishi City Multi S. These manufacturers are often thought of when considering a mini-split, but these are not mini-splits rather fully modulating split systems.
These are heat pump systems which, depending on your energy cost, should be the cheapest way to heat your home. If supplemental heat is necessary, they can work with that too.
Unlike any US system, these can have multiple indoor units connected to one outdoor unit. Each indoor unit is a zone and the more you have the greater your comfort will be. The air handlers are very small, making it easy to tuck them away. This will eliminate the need for over sized complicated duct work, which is one area least understood be contractors. Depending on how many indoor units you connect to the outdoor unit, system capacity can go higher than the nominal rating and operating efficiency is maximized.
These systems do not have SEER ratings as they are smallest in the commercial lines and there are so many indoor/outdoor combinations to choose from. But, they are very efficient as you can see from comparing EER ratings.
The entire system is handled by a single controller that you can be tuck away in a closet while each zone will have a small match book sized temp sensor. Each zone can have its own temp settings and even be completely turned off when not needed (can't do that with the typical zoned system).
With the highly sophisticated controls, component failure is rare as it will shut itself down when operating parameters are outside the norm. Protected from self destruction, Daikin claims an expected life of 20 - 25 years.

Nordyne bought the right to use the Maytag name, Maytag doesn't do anything with central systems.
The IQ system is modulating. The Infinity is 2 stages.
Carrier and the other big names will be playing catch up to the IQ abilities.

I've seen the iQ system in action; it's quite impressive.
The price point is steep, which will keep the iQ from gaining wider acceptance until that point drops, IMO. Rising energy costs may help drive sales a bit, but mainly if the price point is not also driven up by these same costs. I'd love to have one in my home, but kind of hard to justify the cost for an 1,800 square foot house.

I agree, I went to one of there classes here in Houston a few months ago and I agree impressive to say the least. Isn't it funny that when we old school folks "Like me" did not accept NATE or other supposedly industry new achievements or advancements I am a "old school fool". But now when you have something like the IQ technology brought to America by Panasonic and they incorporate that technology into the Nordyne products and they become the flat out leaders in Condenser technology, no one wants to accept that. Don't believe me, just attend one of there classes if you ever get a chance, this thing is miles ahead of anything out there right now, and the person that said this thing was loud, well obviously he has been Blue Oval or Trane washed or just flat out don't know what he is talking about. :rolleyes:

Carrier has had research and development going into variable speed products, for longer than many manufacturers have been on the market. They introduced Puron in 1998, have been using it in their equipment ever since. The Infinity system is on the cutting edge and is their top of the line.
There would be no question in my mind, it would be Infinity all the way.

I agree "anyone" can have research and development going on but it's still not a variable speed leader by no means, unless you can that compressor that had to "STOP" to change speeds modern technology, Carrier should say thank God for Copeland or they would have nothing in Compressor technology. :rolleyes:

Rheem- Box Car condensers-1980
Lennox-Pulse 1982
General Electric-Round Condensers
And so on, The field of hvac is constantly changing with all company trying to secure a share in the market place.So, as technicians and dealers of hvac products why not just say that one unit will do what it was designed to do if installed properly, maintained .
I have sold, serviced, installed Lennox, Day-night, Rheem, Coleman, Goodman, Amana, Trane, American Standard,York,Frigidaire,Maytag, Carrier and also Geo-thermal heat pumps, Water furnace,FHP, Commandaire,Climatemaster.
All have issue in one area or another, there just isn't a perfect piece of equipment out there. Brands are like choosing a car or appliance there are different points to each manufacture. So brands can come and go from one year to the next with different components and functions.
Choose your equipment by the knowledge and experience of your contractor and his ability to perform load calculations into the design of your home comfort system.And get that design incorporated into function.
Just an opinion,

Maytag, fridgid air are what you call, manufactors that ride the coat tales of the bigger brands. I like Carrier due to the product line up, the support they give us, the training they provide my company, They market the product and last but not least the reputation. I have Installed frigid air and I would put it in the same catagory as frazer johnson, Cheap crap with poor design flaws. Maytag has a long way to go before they can say they have proven themselves, Okay they have made a good unit at the end of Carrier last product change. Next year Carrier will introduce it new product line like they do every 3 years and then we will be were we are right now, ahead of the competition and cutting edge technology. Another reason I like Carrier over the other brands is they treat their dealer to a vacation every single year and reward the people who sell a certain amount of product. This year we went on a carribean cruise and they paid for trip,excursions, drinks and even tips. I had a hard time getting a hat off fridgid air. I support products that give it to me in return. Oh two last thing they paid for my last van wrap $3000.00. Was not expecting that. They also gave me A/C, furnace, purifier, Infinity controls and U V lights. That is why I support them. Can you blame me? I didn't think s:eek:!

As a contractor who has installed both systems. I'll give my 2 cents.
I was a Bryant dealer and installed several of their Evolution Systems which are the same as Infinity systems.
They are a top of the line system and if you want a heat pump or need more than a 4 ton system that would be my decision maker.
However if you don't need a heat pump or more than 4 tons of cooling (4 ton was the largest IQ Drive when I did the installs) then I would want the IQ Drive. I think this comes with a furnace but I'm not sure because we don't see those here in South Florida.
It has a modulating compressor and a vari speed evap and condenser motor. You have to use the controller that comes with it. The Carrier can use a 2 stage Tstat and will work.
The IQ Drive is very quiet and removes huge amounts of humidity.
The only down side is it's cost. The warranty is at least 10 years on parts and the comfort pledge is 10 years ( new condensing unit if the compressor quits in the first 10 years) which tells me inverter tech is here to stay.
Nordyne builds the IQ Drive in several brands> Contractors have to be IQ Drive certified to do the install. Check out Nordyne's web site (and Carrier's) and talk with several contractors. Once you choose the equipment the contractor is really the big choice too getting a quality system.

So Don't get me wrong, I can't beleive how little I know when it comes to other products and I have really only givin to manufactors my personal best, Lemox and Carrier. The pulse stole my shorts and we were having to wait for parts in middle of winter for 2 to 3 days, Customers started question us. My team rep has been so helpful with Carrier, that they have fulfilled just about every expectation we have demanded and thats what I needed. so when maytag approached us and said maytag 100% they lost out big time. The rep I see at every home show,probably wishes he had been alittle less demanding.
They have picked up a guy in my area now. He has phoned me for some sub contract work, but im not feeding my competitor.

Here is my thoughts. on the Infinity vs. the IQ
The Infinity works,is proven, and they have a full line.
We were heavely recruited to sell the Maytag brand, so i took the trip to Houston to see the product in action.
the compressor is nothing new so I didn't see any problems there and very quiet. My main problem is the IQ is very gadget based. By that I mean alot of bolt ons. The carrier system is simple and easy to install.
In my opinion the IQ was released a couple years to early. Maybe in 09 they will have the full line. Another problem I had was (Tappan, Maytag, Westinghouse, Figidaire, and I know there is another all have the 23 SEER IQ.
But all honesty screw the equipment go with the contractor you feel is the best and everything else will work itself out.

I that doesn't make them better than you tell me what does.
I don't know. I haven't been in the trade long enough to say product ABC is better than product XYZ. If I was to say that though...I would back that statement up with something more quantifiable from the customers point of view than the fact that company ABC gives me a bunch of free stuff to say it's better.

The Infinity should alittle more beacause you r getting alot more than Frigidaire. 2 stage, communicating, micro tube, 21 seer, quiet, all metal with rock gaurd, back seating valves, forward swept blades.
The IQ drive system is variable capacity from 40% to 118% of nominal capacity, without stopping the compressor. It is fully communicating, 23 SEER, except for the 4 ton which is 21 SEER, has a louvered metal cabinet, swept wing fan blades, an electronic TXV, and is exceptionally quiet.
It has a dehumidification mode that ramps the airflow down, and manipulates the refrigerant flow, to maintain a 35º evaporator temperature during the dehumidification mode.
If you don't need a heat pump, or a 5 ton unit, how are you "getting a lot more" with the Infinity?
mchild
04-20-2008, 06:24 PM
mchild brought up something I have not heard of before.
This sounds very similar to the mini-splits.
My point was not that duct work isn't needed. These systems have both ducted and ductless indoor units that can be mixed and matched to go with the outdoor unit.
For the ducted units, each small air handler will have its own ducts, and thus, be a dedicated zone. Compared to a typical system, when zoning, ducts are over sized by 25%, a bypass duct is needed in most cases, and all the ducts (supply and return) must all be able to get back to a single air handler. This can be a real challenge in some homes and can add to the cost. Also, a zone can not be shut off completely where with the VRV/VRF systems zones can be shut off if not being used.

With out going into specific numbers, do you think the type system you are talking about, all other things being equal, are comparable cost wise to a standard type IQ Drive central system?
I have existing duct work, but a new system like you are talking about would require new ductwork obviously.

NEW YORK -- Constantly changing business conditions -- when India and China heat up, the US housing business slows to a crawl -- make juggling one of Tom Bettcher's key job descriptions.
Managing often-conflicting business trends is all part of a day's work for Mr Bettcher, the business leader of Emerson Electric Co's Climate Technologies division.
The $US3.6 billion ($4.09 billion) division makes components used in heating, ventilation and air conditioning (HVAC) equipment for customers like United Technologies Corp's Carrier unit, Johnson Controls Inc's York division, and Trane Inc, which is being bought by Ingersoll-Rand Co Ltd.

.
I don't know what your cost of the IQ system would be, but I have heard it is a pricey system.
Only a contractor on site could tell you if any or all of your duct work could be retained. I was able to keep all of mine and split it into four zones. I have two duct systems, one for the first floor with it going basically front to back. It will be split into two separate duct systems with one air handler for the front zone and one for the back. To accomplish this a section in the middle will be removed and the new air handlers will be back to back. The second floor duct system is also front to back and located in a conditioned attic. It will have a similar treatment.
The front of my home faces east and the back west, so I have a fair amount of load diversity within the home. With this system each air handler is sized for the maximum load it will have. Thus, the east units will be working more than the west in the early hours of a summer day and vice versa in the late afternoon.
Zoning the home to the load requirements will allow for a better match up the compressor output to the true load on each zone. Could also allow for a smaller overall systems too. Your contractor will have to investigate those issues.
The compressor will normally run as low as 25 - 30% of nominal capacity and with its ability to change speeds to meet the load it will have extremely long run times. This is how the system is able to provide very close settings to the t-stat setting and keep the humidity very low. Both the indoor and outdoor unit are very quiet.
Also, these systems put out much more heat at lower temps than any typical heat pump system. Often no supplemental heat is required.
Daikin has the largest market share of the VRV/VRF systems. If you choose to go with their equipment they will provide your contractor with help in the design of the system and generally will be on site when it is commissioned.

If he is putting this on an oil furnace on a 24ANA1 will not work,it only works with an IFINITY heater and the INFINTY control which will not work with the oil heater.FYI! Page 7 Experts Reference guide 2006

I two was looking at the IQ vs Infinity vs Trane XLi19. I currently have a fully variable xv1500 trane thats been working for 17 years. 4 service calls isn't bad. My reason for looking is outdoor condensor aluminum is breaking off and can't clean very good. I have had variable speed every house and office since buying XV unit. The humidity removal is awesome and I want the exact same in new unit. {Low humidity Low noise Freeze out inJuly August}

Manny, you needto talk to your Frigidare distributor,on the perks that you are recieving I distribute the Tappan product and we do all of the things that Carrier is doing for you.What are the design flaws that you see in the product?You said wait until next year for Carriers new product line ,well wait unil Nordyne releases there new line. The Nordyne product is no where near a Frazier Johnson,maybe several years ago you could say that but you would have to go way back.

Another reason I like Carrier over the other brands is they treat their dealer to a vacation every single year and reward the people who sell a certain amount of product. This year we went on a carribean cruise and they paid for trip,excursions, drinks and even tips. I had a hard time getting a hat off fridgid air. I support products that give it to me in return. Oh two last thing they paid for my last van wrap $3000.00. Was not expecting that. They also gave me A/C, furnace, purifier, Infinity controls and U V lights. That is why I support them. Can you blame me? I didn't think s:eek:!
Good info for homeowners.

I agree, I went to one of there classes here in Houston a few months ago and I agree impressive to say the least. Isn't it funny that when we old school folks "Like me" did not accept NATE or other supposedly industry new achievements or advancements I am a "old school fool". But now when you have something like the IQ technology brought to America by Panasonic and they incorporate that technology into the Nordyne products and they become the flat out leaders in Condenser technology, no one wants to accept that. Don't believe me, just attend one of there classes if you ever get a chance, this thing is miles ahead of anything out there right now, and the person that said this thing was loud, well obviously he has been Blue Oval or Trane washed or just flat out don't know what he is talking about. :rolleyes:
I'd probably be more "old school" if I wasn't around more complex HVAC systems all the time. Since I spend my days around controls that modulate, vary, monitor, alarm, trend, etc. and then come home to my residential system that does little more than switch on and off via a thermostat, with no genuine ability to adjust itself to the load; when I saw the iQ system I was impressed that such a concept could be had in a typical residential setting, like mine.
Only the price point made me balk...and it's hard to justify ripping out a system that is working well to install something I can't afford. :D :o I know the comfort and energy saving gains would be there...but I wanna build my wood shop now vs. buying the iQ...of course I could put the iQ in the shop...hmmmm..... :D

Does anyone know where I could find a picture of the XV15? I would really like to see what they looked like. Dumb, I know, but curious.
Also,
I know that Carrier's Infinity control is really good, communicating with all components, but isn't the only difference between most other manufacturers two stage condensing units, and Carrier's Infinity system the inside fan controller and the outdoor fan controller? I know you can set to dehumidify, and it has a little more control over the indoor fan, and it also tests the static pressure of the duct and filter system with torque curves and amperage, but other than their Bristol TS in the 24ANA7, isn't the Copeland Ultra Tech used in the 24ANA1 the same compressor used in just about every other 2 step manufacturer's condensing units?
Just curious.

Sure do thank you. I have quite a few local pictures compiled ov old GE around here. I want to get some more before summer really kicks in. I think people will start replace these units, even if they still work.
So, when did Trane go to the weather guard top? That would have been when they still had the wire tops and weather beater tops?

When I was buying fridgid air equipment, I couldn't even get a frickin baseball hat or even lunch and in Edmonton let me know when or where you next billboard sign Campaign will be,Last year did not see 1 fridgid air. Carrier had over 8 at 1 Time and for 2 months. They are doing more commercials this year than last year. If you seen what I seen in las vegas 2 years ago at the dealer meeting and was only a proto type but they are do to intro duce it soon. I will be at the factory in Indy May 1 08 so I will question the engineers on why I should not switch to the nordyne product and if they can't answer me in a positive way, I will take on new product, I am in no way tied too any manufactor, my job is to make sure my customers have a choice of good of product along with excellent service. Oh 1 more point, from a dealers prospective, Carrier is very competive and yet standing on cutting edge technollogy. Have a good day Tim.

Must be the Canadian spelling.:rolleyes:
The Infinity,will handle dehumidifcation just fine as it does here in steamy Florida.Hybrid Heat (dual fuel,gas furnace and a heat pump),might be worth looking into.
The IQ may do as well,haven't heard great things about them from those that have installed them,so I'll leave it at that.
