Replacing 20 year old system

[imnosupermom]

I have a 1225sq ft house in SoCal, currently with a 2.5 ton Payne system. I have had 7 companies out to give me estimates on new 3 ton systems and have done a bit of research, but am having a hard time making a decision.

I'm not sure its possible to find, but I'm looking for some nonbiased opinions.

I can get a 14 seer Rheem (R22) with a variable speed furnace for the same price I can get a 13 seer Carrier (choice of R22 or Puron) with a single stage furnace or a 14 seer Carrier with Puron with single stage furnace.

The Carrier guy is throwing in an extended warranty and 2 years of maintenance. He is not a Carrier authorized dealer, but gets permits and seems like a nice guy. The Rheem place is an authorized dealer, but does not get permits.

Not only am I torn between Rheem and Carrier, I am still torn between R22 and Puron. While most my research on the net says puron is the way to go, only Carrier sales guys were trying to get me to go with the new refrigerant, everyone else was really pushing to stay with R22.

TIA!

[dash]

A lot of the "most everyone else "guys ,have little to no experience with Puron/R10a.


I'm a Carrier guy ,but go variable speed with Rheem ,if that's what the budget dictates.

1.V/S
2.SEER
3.Puron

First, 3 tons for 1225 sq ft seems excessive. If your current 2.5 ton doesn't do the job, may be duct issues not just undersized. Spending a little money on insulation or window tinting may be a better investment than a bigger A/C.

The Rheem system is great equipment but pricing scares me. Is the Rheem dealer particularly low and cutting a corner or is the Carrier dealer particularly high? Read the fine print carefully to be sure the Rheem guy is doing everything the Carrier guy is doing. Not pulling permits if required by law scares me too. On the other hand, what does it mean if the Carrier dealer is not authorized? Where is he getting his equipment? How about future warranty & support?

[imnosupermom]

Baldloonie,

All the questions you ask are the questions I've been asking myself and why this decision has been so difficult. Both the Carrier and the Rheem guys prices were much higher, but the Rheem guy and another Rheem guy started a bidding war with each other and then my Carrier guy lowered his prices and added in the extended warranty.

I was actally considering going cheap with a 10seer Rheem with single stage furnace vs the other Rheem guy with a 13seer VS, when the 1st guy said he would let me talk to his Rheem rep to get a better understanding of if I needed/wanted VS. I got another call, and when I called him back he said he had talked to his rep and they could give me the 14 seer VS at the price he originally quoted me for 14seer single stage which was a few hundred more than the other Rheem guys 13 seer VS. Hope that made sense.

I don't think the Carrier prices are necessarily overpriced as I've had other Carrier bids that were even higher. Part of the issue is rebates I get from the electric company and whatnot. The Carrier guy gets his product from US Air I think its called. He tells me that it is fully warranted by the manufacturer and it doesn't matter that he is not an authorized dealer. Of the 7 bids I had only Sears, this guy and one other get permits even though they are required by law. Sears and the other were several thousand more though for the same product.

I had our ducting looked at and was told it was sufficient. None of our windows get much direct sun light and we have little attic space for insulation as we are single story with high vaulted ceilings. Our current coil is completely blocked by the morons before us using the wrong size filter, so that may be hy we only feel a trickle and why our house doesn't cool below 80.

Thanks for all the input!

[simpleman]

Thats so funny..they started a pricing war and even the carrier guy follow suit.

Hey Supermom..maybe you should let them keep fighting.Heck
at this point you might even get two stage equipment for even a lower price then whats was quoted before.

LOL!

[love_hvac]

I wouldnt go with a rheem, im my opinion they are junk. I would recommend getting some estimates on american standard or trane. If your going to spend the money... get something good. Good luck!

[imnosupermom]

I had an estimate on a Trane and it was more than double the price for the above mentioned systems. I could get a 14 seer American Standard VS for about a grand more than the Rheem or Carier, but I'm already maxed out budget wise.

[BaldLoonie]

I wouldnt go with a rheem, im my opinion they are junk.

Care to be more specific and your credentials for bashing a popular brand?

I am a homeowner in Virginia. You will get what you pay for. Make sure the big difference in prices for systems of similar capabilities are not due to the prices for the equipment, unless you are getting manufacturer's promotion prices. Could be the differences will be between CHEAP installation and GOOD quality installation. It looks to me like the operators who do not get permits are bootleg guys. Stay away from them. Do they have licenses if required by the state? Insurance? Stay away from CHEAP, it will cost you later, maybe big-time. Go with contractors with good reputations. How long have they been in business for themselves? Check with your Better Business Bureau and county/city consumer affairs office for any complaint record before your final decision.

Find someone to do a Manual J calculation on your cooling/heating requirements. Like Baldloonie said, 3 ton seems excessive. That's the capacity I have for my 2400 square foot two story with design temp of 95 degrees. And half of the top floor is vaulted ceiling, like yours. But nobody can tell for sure without spending 20-30 minutes in your place to check out the construction, etc for Manual J which takes a few minutes in the computer. If the system is oversized, you will not be comfortable.

By the way, one more bid would not hurt. Check with Home Depot who will send you a contractor with Trane. Compare that with Sears, and then compare all the others with those two. If there are big differences, you should be able to pick out the reasons, or there is something fishy about the low bids.

R-22 or R-410/Puron? That should not be a major factor in your decision, just a tie breaker, maybe, if you think you cannot live without the R-410.

Hope this helps.

Scares me also I worry about a City as big a Houston shutting down totally if we all pulled permits to set a condenser or replace a coil, they have just gone to far but it's the almighty dollar that these cities are after to fatten up their budget that they never do any improvements with any way.

Got to be an American Standard salesman are someone that is clueless about Rheem/Ruud which I would put up against any brand as for as performance or quality.

Dash, Baldy:

You guys are some damned smart professionals and I respect your abilities tremendously. But for the life of me I can't understand why you guys entertain this ill-conceived thought process. It's like were at Wal-Mart trying to decide what goodies to put in the basket. As you know so very well Mom isn't buying goodies she's buying a service. She should spend 95% of her energy on finding the most competent contractor. Whatever that contractor recommends IS the best choice, period. I know you touched on it a little. But Al is the only one that’s put a fine point on it so far. And he’s a homeowner!

Mom,

You're approaching this in a very normal way. Most homeowners focus on brand. But you've got to understand that arguing HVAC differences is like arguing muscle cars. The Ford guy says his will do zero to sixty in 5.2 seconds so the Chevy guy says his will do it in 5.0 seconds and proceeds to do the chicken dance. Who gives a rat's behind? They're both wicked fast! The same goes for HVAC. All of them have their stupid little features that they claim exclusivity on. But so what? Any mainstream brand will serve you well.

But here's the real catch Mom. Taking our car analogy further: What if instead of that Ford being assembled in a billion dollar plant with a thousand computers and a dozen eggheads watching, that car was assembled by a guy who just got paroled last year and started building cars because of the vocational training he took in prison? You'd stop caring about the brand and features and start worrying big time about the schmuck that's building it!

That's exactly what you're dealing with Mom. First of all Trane, Carrier or whoever hasn't got one thing to do with the design and installation of the system. They are bit players as far as I'm concerned because all they do is supply parts. Second, that nice Carrier guy or any of the other sales jerks you've met aren't likely to be the ones installing the system. They've got crews and you don't know them from Adam. Third and crucially, painfully FEW do an installation by the book. I'd guess that MAYBE one and if you're super lucky two of the contractors you've met will even come close to doing everything (http://hphaa.com/services/installation/installation.htm) they should. That list could be four times as long if I had the time to write it. And unfortunately, even some of those that do perform truly superior (http://www.hvac-talk.com/vbb/showthread.php?threadid=38790) installations will push garbage like this (http://hphaa.com/editorials/index.htm).

Call me a negative alarmist if you like. But I use to work for second largest so called reputable residential HVAC contractor in my area. Their sister company was the largest and I got to know them well. Virtually none of their systems got put in by the book. Sure they got by and customers were generally pleased. But few customers have a clue about how a system should perform and how it should be installed. They've dealt with wretched HVAC systems all their life. And when the contractor comes in and takes wretched and improves it to only bad, they're happy. I'd say that trade propagandists have performed masterfully. We can give our customers mediocrity, sell them snake oil and they love (some of) us for it.

I hope that helped. If not, at least I feel better. :D

[imnosupermom]

Thanks for all the feedback today. I appreciate it and feel much more comfortable making a decision.

I've got one last question... my original bid for the Rheem single stage did not include a thermostat as I have a new digital one and didn't need one. If I end up going VS, can it use my regular Hunter one I got at Lowes or does a VS require a special one that I would need to make sure gets written into the new contract?

Thanks again!

[Irascible]

I'm glad you took my advice to heart. :rolleyes:

No special thermostat is needed.

[imnosupermom]

I did take your advice to heart, but there is only so much I feel I can do on my end to ensure I am picking the best company. Not to mention I was in a car accident Friday and feel like dog crap...

I checked the BBB, and both Rheem dealers get an A rating and have been in business years. One showed 2 complaints (in 36mo), the other none. The Carrier guy has a BBB (tripple B) rating, but no complaints in 36mo, but his license is expired which I found interesting.

The Rheem guy who is also the American Standard guy called me this morning to see if I had made a decision. I told him that I thought the other Rheem guy had made an offer he could not match. We talked for a few and he called me back about 30 minutes later. He is offering me his 14 seer AS VS at the price he quoted me his single stage before, which is less than $500 more than the Rheem. This guy is the one with no complaints with the BBB and will get permits if I request them, he will just add it to the price where as the other guy wanted about $300 to get permits and strongly discouraged them. Ii'm under the impression that the guy I have been speaking with will be present at the install and is responsible to make sure everything gets done how we discussed.

Just so you know, I made more than 30 calls to local HVAC companies of various brands and could only get 7 bids. Most companies wouldn't schedule an appointment when I called and never even bothered to call back. Its funny as a home owner I get so many solicitors for products/services I don't need and when I'm ready to fork over some serious cash I practically have to beg someone to take my money.

edited to add... am I missing something? What else should I be doing? What else can I do? We are fairly new to the area and I asked everyone I know for referrals, but nobody has really BTDT. One friend's mom just got a new system, and well the company hasn't called me back. I called before the holiday weekend.

You're doing fine. Excuse my sarcastic remark above. It's just that when I devote nearly 500 words to a single homeowner I crave a little more response than the "thanks to everyone" reply. I'm a bit narcissistic that way. ;)

Your comment about the lack of response reminds me of a customer who I got because I was responsive. She says to me one day: "I'm beginning to think that all contractors are independently wealthy because they never call me back!!!"

Ditto.

Sorry about not giving you more personal attention. :-) Blame it on pain from the car accident.

If you are in a humid climate,I'd get a stat that has the ability to set the humidty ,for cooling and control the fan speed to dehumidify,as a minimum.You can add a seperate control for this,if you want to reuse your stat.

GEEZ,IT JUST KILLS ME TO SEE TWO COMPANIES SO DARN HUNGARY TO CUT EACH OTHERS THROAT.ILL CRACK UP OVER THAT ONE-I CANT KEEP UP WITH MY NEW INSTALLS OR SERVICE WORK-WHEN YOU DO IT RIGHT YOU DONT HAVE TO CUT EACH OTHERS THROAT -WORD GETS AROUND-YOU DONT HAVE TO ADVERTISE EITHER,I NEVER HAVE AND HAVE ALWAYS HAD MORE THAN I COULD DO YEAR AROUND.WHY DO YOU GUYS TRY TO OUT DO EACH OTHER-ISNT THERE PLENTY FOR EVERBODY?IVE NEVER HAD THAT PROBLEM-THANK GOD-I JUST DO IT RIGHT.
THANK YOU,

[imnosupermom]

It just kills me when people are so angry they must yell at me by typing in all caps.

[42yrs exp]

I think that you should get seven(7)more estimates, and after that get seven more, and after that get seven more, and after that get seven more, and after that get 777777777777777 more. No wonder you are confused. Good Grief! Boy am I glad you did not call me.

[imnosupermom]

Hmmm, someone doesn't like educated consumers???

I've never bought a central heating/cooling system before. There are several brands to choose from and thousands of dealers. I was just doing my homework so that I could make the best decision for me and my family.

I get a carfax before I buy a used car and I check consumer reports. I test drive a few different makes/models to narrow it down then I find the best overal deal (meaning person/dealer, price, perks, etc.) and buy the vehicle. I don't just look in the penny saver and find a yugo and go get it. I don't have the option to test drive AC units, so I had to educate myself the best I could.

[kawkvulcan500]

I'm confused. I thought R22, like R12, was/is being phased out?
But manufacturers are still building systems with R22?

[kawkvulcan500]

I am also considering replacing a 20+ year old unit.
I am thinking of relocating the condensor unit outside to the otherside of the house. It will be approx. 50-60 feet away from the evap coil. Is this too far?
Will I lose unit efficiency?

It's in the backyard where it is an eyesore and in the way of a future deck. FYI.

[Irascible]

mom,
The ratio of bad contractors to good is probably 20 to 1. So if you blindly called you'd need 20 estimates. But if you narrowed it down by doing a little pre-screening then maybe you found a good one out of the seven.

Of course I define contractors that just go along to get along as being bad. They may put in OK stuff that works. But mediocrity is their way of life. Manual D & J are alien concepts. Custom engineering the diffuser selection for proper throw to each room is a few too many syllables for them. And the only thing "air balancing" means to them is having all four tires inflated to the same pressure.

If you're just a cheapskate looking to get something for nothing from a desperate contractor willing to work for minimum wage then you'll get what you deserve. But if you're looking for that one in twenty contractor that actually knows how to make a kick a** system then get 7 more bids if you have too! I'm right there with you.

vulcan,
They can't make R-22 equipment after 2010 and they can't make the R-22 refrigerant after 2020. Existing stock will be around for a long time after that. And drop in replacements will be available. At this exact moment there's no clear advantage to getting an R22 system or a R410A system. They both have pros and cons. But as it stands I think R22 equipment is still the higher volume product by quite a bit.

50 or 60 feet is not a problem. In some cases a suction line will need to be made one size bigger to compensate for distance. But that would most likely be true only if the current line is already a bit on the small side.

[Edited by Irascible on 06-08-2005 at 09:10 AM]

[imnosupermom]

I wasn't being a cheapskate, just trying to get the best deal for my money. If I could actually get 7 more companies out here to find a competetively priced one that got pemits and really feel like they would do it by the book I would. But like I said its not easy even getting them to return calls.

BTW, my dad bought a new heat pump about a year ago. He narrowed it down to the brand he wanted first, then had 6 bids, went with the first one (who was not the cheapest).

I'm really glad this is a purchase I only have to make oce every 15-20 years.

[mark beiser]

By entertaining the bidding war, you virtually guarantee that the eventual installation will be substandard at best.

Bid is an acronym for Beat Idiots Deal.

A quality contractor will give you a proposal for all of the required work, possibly with some options. Usually any lowering of the price will be as the result of lowering the level of equipment, or dropping options.

If the "contractors" you have bids from are dropping the price of the system that was already much lower than some of the other proposals, and are offering better equipment at the new lower price, RUN FROM THEM! You will not be getting a quality installation from them.

You are doing fine. And this is a learning process. It's just that buying HVAC is not quite like buying a car because HVAC involves local labor and skill as a major component of the whole deal. Please review my first post on page one of this thread. When I wrote, I had the feeling you were encouraging a bidding war. When I buy a car, do my research and rove around dealers like you do, but when I start talking price, I say I want their best price NOW, and when I walk away I let them know I consider this to be their best price. I do not share pricing info with other dealers. I do not always buy the lowest bid either.

Have you called Home Depot for a Trane offer? Many of the pros here hate the idea of Home Deport and Sears being in the HVAC market. But for you, this would be a sanity check on what the other contractors are telling you. And by the way, at the Trane web site, you can find a list of local Trane dealers.
http://trane.com/Residential/DealerInfo/DealerInfo.aspx
Hopefully there will be a few who have a red icon by their names designating "Trane Comfort Specialist."

Good Luck,
Al

I would hope one call to Home Depot will suffice. You already have a lot of info.

I assume your dad is not close by, or you would have gone to his contractor. But he should be able to sort through all the details with you and give his advice. Not that you have to take it or course.

Also, think back as to whether you have shared a lot of information from one contractor to another. Some sales people will ask if you have had other contractors visiting and will pump you for info. I'd rather just say yes and little else. Let the guy visiting you at the time stand on his own two feet. Of course you should use your knowledge to help him focus on the features you want and to stay close to your budget, but you need not let him know who said what. Otherwise, some contractors will just bad mouth the competition, sometimes with lies or through ignorance.

By the way, back to your first post about the 2 1/2 ton Payne and the 3 ton bids. Manual J can solve that discrepancy. But if your house is similar to others in the neighborhood, it might help to learn what your neighbors have done to replace their original systems, especially if you can find one or two where the orientation to the sun is the same. It is very unusual to find an original system that is undersized. Usually it is oversized.

Good luck,
Al

[imnosupermom]

Home Depot was one of the companies that never called me back. However when one of the guys I had called on my own came he was a Bryant and Trane rep and I asked if he did work for HD cause the name was familiar and he said yes... I think it was the same company that was suppose to call me for HD and never did. The Trane estimate he gave me was huge... 5 numbers before the decimal point, lol.

I also started thinking this morning about what a nightmare it was buying carpet from HD and working with subcontractors getting it installed, I wonder if AC would be similiar.

I honestly wasn't trying to fuel the bid war. Mainly what I did was say our top budget ix X and I'm considering these brands. I have a feeling I did provide more info to the competing dealers than I should have.

My dad is over 1000 miles away. None of the neighbors I know have replaced their system yet.

It is all a learning curve, right...

It is very unusual to find an original system that is undersized. Usually it is oversized.This is extremely good advice. Don't upsize your system just because you want 'more cooling'. As you've already said, the existing system is broken because of the clogged coil. Also note that you can't size a system by rules of thumb such as so-many-square-feet per ton.

Make acceptance of any proposal contingent on a Manual J heat gain calculation, with a credit for each half ton if it turns out you only need 2.0 or 2.5T

[imnosupermom]

I'm guessing the manual J calculation isn't just something I can do. :D I have a feeling I'm driving the guys as crazy as I'm driving some of you. I did question yesterday if 3 ton was too big and I should stick to 2.5 and he said it was fine, but didn't do the manual J.

Top right corner of the page there's a bulls-eye. You can indeed do a load calc yourself.

What he siad should get him off your short list of contractors.

Larger system= Larger Ducts.

You need to majke a list of theadvice items on this thread and stick to them,to get a good job on your home.

[imnosupermom]

I already had the ducts checked to make sure they could handle the 3 ton system and that was one thing all contractors agreed upon.

How did the test them or did they just "take a look"?

Not trying to be a pain,but didn't they agree no Man J is needed to determine the correct size.

[imnosupermom]

They just looked in the crawl space and said 'they can handle a 3 ton, but no bigger'. No testing involved. Nobody mentioned a manual j calculation. I think they said I had a 6" going into the bathroom.

K, I did the manual j (guestimated best I could) how do I interperate the results? I've got a heat gain # and a heat loss #. Which # do I use and what do I divide it by to get the tonage I should use?

[Irascible]

If your version is similar to the pro version then you can click on "reports" and then save one of the reports as a .pdf file. Post it or e-mail it to me and I'll post it.

[Irascible]

(I posted the calc before I looked at it. But it doesn't have the info we need yet.)

[Edited by Irascible on 06-08-2005 at 02:20 PM]

[imnosupermom]

So the big question is, what tonage would be best?

[dash]

Loking in the crawl,like using tons per sq ft is not very accurate.

Contractors seldom oversize the duct system,more are undersized then oversized.

With a straight face? What a disappointment. When things settle down, I would report that guy to your local Home Depot store's top manager. 5 numbers could be good for two systems in a mansion. When I checked with a Home Depot's contractor last year for my daughter's condo, he priced out reasonably exactly where I expected.

[hugodrax]

If your trying to get the cheapest install you will not be happy down the line.

You will even probably pay a higher electric bill than what you should be if it was properly installed.

go to the Wall of shame and see what cheapest gets you.

Concentrate on service and proper install.

[Irascible]

I use to refer people to the wall of shame myself. But you have to go through a lot of service call stuff, commercial stuff and Payson stuff just to find a few botched resi installs.
