Yes it is,but there is no communicating board in the condenser. The only reason that air handler is matched with that condenser is because it meets the tax credit criteria. I assume the blower motor in that model is really the determining factor in achieving that efficiency.
that tcont900 stat will run a single stage condenser as long as the a/h is a communicating a/h

the reason to use the 900 with a single stage system is;

you will be able to use many airflow benefits like dehumidification on demand

so it's a good idea IMO



.
 
this is why NC code is now requiring us to do a block load calc on all c/o now starting 2011.

I agree I can't stand the price shopping crap, I could quote 500 jobs a year and get 50, That's alot of free labor on my end for what.

If you already are my custome then yep I don't charge the quote, but if you just call me out of the blue, it's a service charge. whether it's diagnosing a trouble call or diagnosing your system eligabilty for an upgrade you are gonna pay me.

and this is something we need to stop in this industry. A homeowner get's 7 quotes WTF.

Interesting, so when the A/H is in communicating mode it still puts 24v out to Y1 and Y2?
 
look at the quote it says single stage

this is technical stuff i don't want to cause any trouble

when it comes to wiring, we can talk about this in the pro section, but not here

.
Yeah, fair enough. Still waiting on pro status though, but I was definitely wrong on the 900 not working. Thanks for that,i always assumed the other terminals were unusable. It is a great controller i'd use it on every system if i could.

I am the director of a non profit business, which I founded. I have to compete for drying up government funding, against much larger businesses with grant writers and lobbyists. I understand competing for dollars, and how unfair it can be.

Most consumers, including yourself, compare prices everyday on everything from food to purchasing a car. Why should your business be any different? And how do you as a business owner say you don't care about the plight of the very people you depend on to stay in business?
maybe all the HVAC companies need to charge for estimates

I erased my post because I realize this side discussion is off topic. We can agree to disagree.
can you answer my question about what you do to earn a living?

I am a GC and Mechanical contractor, I don't make money if I bid work for a person taking 7 bids for a changeout and don't get the job, bids cost me time which is money.

I make money by either servicing their equipment, selling them a new unit, fixing their broken system, or charging for consulting.

Buying a new a/c system is different than comparing a price on a commodity such as food, or other commodity items like it.

When i go to Publix or some other place like it and I see something costs $5.99 a lb, I didn't have publix come out to my house and give me a bid for it, i drove there and checked the price myself, can't compare the two.

If you are in a non profit, you are making money somehow, either through grants or other ways to raise money, then you pay yourself, staff and other overhead, you don't have to make money, but you do have to bring in more than you spend or you go out of business.

What does your non profit do?

I am bidding some work for a non profit organization right now and because they are a non profit I am trying to bid it as close to my cost as possible, but if I screw up, the job will cost me money, but they don't care as long as they get the job done cheap, and so far no one else that is qualified to do the job is bidding it.

They expect people who bid work for them to not make money because they are a non profit, yet they have paid staff.

I run a drug prevention agency. Just because the agency is non profit, doesn't mean that they don't have money to pay for work. It may be that they can't pay for your work through their existing dollars. Funders tell you how you can and can not spend your money. For instance, I couldn't pay for our fan through grant dollars, so I had to get a contract to make the money to buy a van. However, I still believe they should pay an appropriate amount for your work. If you want to give them a deal, see if you can write off the reduced amount.

I am not arguing against contractors making money. I am just sharing the view of many of us consumers who find ourselves having to invest a lot of money into equipment and work with little information to judge what is a fair cost for this work. Yes, I agree that there are those who go for the lowest dollar amount, but that happens in most things that people pay for.

From a contractors view, should the consumer just go with the first person that comes out? How does the consumer learn what is a fair price?
 
I can sometimes, (keyword there), go into a heavy bid situation and be as thorough as possible. Catching a good bit of things along the way that will help me get the job along with doing a Man. J, whole house.
But, in an almost equal # of those jobs the owner will take the observations and either discount them as me trying to screw them or go back to other bidders to get that stuff added, of which 1/2 of those will tell them I'm trying to screw them and it doesn't need done.
 
Re: Multiple estimates

Hello,

I came here looking for some reasonably objective info to help me choose between the bids I'd received, and learned a lot from many of you - thank you!

I read this thread because a model number search brought it up, and joined the forum just to add my thoughts to this...

I can understand the frustration of those who've complained about customers getting multiple bids and "wasting their time", but what is the average uninformed (or only slightly informed) person to do? Everyone from the BBB to Consumer Reports to state regulators recommend getting at least three estimates for things like A/C, roofing, etc.

Then I come here and learn of all of the evaluations that *should* be done by an A/C company, yet none of the companies that gave me estimates had even suggested any of it. It's not that they told me of what should be done, and what it would cost to do it right, and I was too cheap and turned them down - it was never even mentioned as an option.

So what then should I do? Keep calling companies out to give estimates, until someone gets it right? Aren't I just wasting more people's time?

Here's the condensed (well, semi-condensed {sheepish smile}) version of what happened:

I divide my time between FL and VA, so I'm not here year round. Late last summer, the HP wasn't cooling well, icing inside. Called original installing company, they added freon, found a small leak, said it would need expensive repair, or replace system. It seemed to run fine the rest of the year, so I decided to wait as long as possible. (Hard for me to afford replace or large repair.)

Come back down a few weeks ago, to find system again not working well. Called different (large local) company (who did a system for my brother in law) for a "second opinion" - they say freon level is still good, but compressor is dying. Very expensive compressor replacement, or replace system.

Trane system is 13-14 years old - ok, I'll bite the bullet and replace the system...

So, I asked company who was already there for an estimate - I got a verbal estimate that seemed high, with the pitch that his manager will often make a deal and take some off the price, or maybe do some attic insulation for free with system purchase/install. Seems this company does this also. This made me wary - nothing in writing, and sounding like a bad used car salesman - with the manager in the back office making deals and throwing in some free undercoating on a car... :( Oh yeah, and he also spent at least half the time trying to sell me on a very expensive air cleaner...

So, then I call the company (medium size local) that put in the current system, and ask for an estimate on replacing it. They come out, look at the tag on the inside unit, look at the tag on the outside unit, then sit down and write down an estimate. He's gone within ten minutes, without asking me any questions, or looking at anything else in the house. His estimate is nearly $2000 less than the first guy, for what seems like a similar system. (3 ton single stage 15 SEER Carrier, v. 3 ton single stage 15 SEER Trane from the first guy.)

Ok, now I'm even more confused... :(

So, I call a third company (medium size local, don't know anything about them other than they've been in business here for decades) for an estimate on replacing the system. Guy comes out, looks at the old system, has me run it, takes temp at all the ducts in the house, asks how well it's worked for me up till now, how long did I plan to stay in the house, etc, etc. Asks habits, thermostat settings, etc. Suggests variable speed AH to remove more humidity, especially when I'm gone and thermostat is set at higher temp. (First I've heard of it, sounds very useful!) Writes estimates for two different systems (Trane and Amana), and explains the differences. (Both 15 SEER 3 ton single stage.) His prices are within about $100 of the second guy, but will do much more for it - include the variable speed AH, change the lines v. flushing them, change the breaker, etc.

Sounds pretty good overall, and I do have my recommended three estimates at this point - but that first verbal one was weird and didn't seem legit, so I figure to play it safe and get one more...

Call fourth company (again, medium size local, been here for while). Guy comes out, does much more than the second guy, but a little less than the third. Writes estimates for two systems (both 3 ton single stage 15 SEER - Trane and Carrier). Comparing his Trane estimate to the third guy's Trane estimate, and adding in everything this guy will charge extra for (variable speed AH, change lines, change breaker, etc) to get it as close to "apples and apples" as possible, he's about $1400 higher than the third guy.

Well, then I guess I've done all I can with the estimates, now to do a little hunting online - see if there's a trend in repair problems with any of them, or any knowledgeable objective advice that would give me a good reason not to go with what seemed like the best of the three - both in price, and in the time/effort taken to at least make a better guesstimate (as I know now) of the best system for my needs.

Which is what led me here yesterday...

While I'm reading, a friend calls - knows I'm getting estimates, and insists I call a friend of a friend who recently moved here and started his own A/C business, and supposedly does good work. Ok, I've nothing against "the little guy", I'll give a small operation a chance... He comes out, looks at the inside and outside units, asks me how well it's worked for me (fine till now), then tells me I need a 3.5 ton. Tells me that he's been doing this since he was 12 years old, and the new units are in essence rigged to meet the SEER numbers and don't put out the same cooling, and that I *have* to go bigger. He calls back later with a verbal estimate of about $1100 less then the estimate I was ready to take (from the third company), for a 3.5 ton Goodman.

No thanks. Leaving aside the brand issues and how they apply to my particular circumstances (this is already too long!), I have learned enough in my reading to know that one of the side effects of a too large system is not removing enough humidity, the exact opposite of what I'm hoping to actually improve a little with the variable speed AH.

So, no, these multiple estimates haven't just been about price. That is a major issue for me (enough so that I can't afford to add hundreds of dollars to the cost of the replacement, to have someone do all of the evaluations that "should" be done) but it's not the only one...

In the end, I got three estimates that made at least some reasonable logical sense, I spent a day reading various sources of info online (this forum being the overall most helpful to me), and tried to apply what I'd learned to my own circumstances, in deciding which system to buy - then made sure the installers were certified/factory trained employees. I've done about all I can afford to do, and then I rolled the dice... {shrug}

Perhaps, in a more perfect world, there would be a compromise that was fair to both customers and companies - one that might work would be A/C consultants that did nothing *but* the evaluations/recommendations. You paid someone to come out and objectively tell you what you needed, who didn't have a stake in selling you anything. Then you took that info and comparison shopped the installers by quality of work/price/etc. By phone/website/salesperson/whatever... Then the customer feels confident they are getting what they need, and can more easily shop around - without wasting the time of the more highly trained people... More efficient for everyone... Just a thought...

Well, if you managed to read all this, thank you for your patience/interest! Maybe, for those of you in the business, it might temper some of your frustration - to have a little insight into how frustrating this can be for the customer as well... This past week should be a horror story of how bad things can be out here - but it is, I'm afraid, much too common... :(

It's ironic, when you stop to think about it - customers are criticized for getting multiple estimates, because we are afraid of being taken advantage of by contractors who will either sell us what we don't need, or overcharge us, or both. Then we come here to get better informed, and learn that we have in fact already been taken advantage of (in the estimating process)... :(

I thank all of you who have shared your knowledge, and your knowledgeable opinions - it's been educational, and much appreciated! I doubt I'll post again, unless someone has a question about what I've written.

Take care...

Non-profit is a misnomer. There can be extensive profits. The difference lies in the structure of the organization, where the corporate (or other structure) is a trust, where the profits are held. This differs from a for-profit organization, where profits are directly distributed to owners, or to stock holders in the case of corporations.

So yes, 'employees' of NPs are paid, some handsomely. Did you happen to see the expose on NPR executive salaries? Some positions were paid more highly than corresponding private sector positions.

Sorry, don't have the link handy.

Let me give you my take on your experience with multiple quotes.......

What consumers need to understand is HVAC systems are not appliances. If you can find the same refrigerator at home depot for $50 less delivered to your house then that's a good deal because the only skill required is plugging the cord into the wall and connecting the icemaker.

When I come to your house for an estimate, I have to determine what kind of consumer you are....

1. are you looking for the cheapest price because you think the "hvac boxes" are just "appliances"?

2. Do you want a system that is integrated with your house, to provide excellent airflow and comfort, installed following all manufacturers instructions, local codes, correcting rooms that don't heat or cool properly, taking into account any subsequent or existing upgrades to your home-replacement windows, insulation? ACCA Manual J,D, S performed

I have to find a solution between the 2. The number 2 solution is what I would do in my personal house. The number 1 solution I typically WILL NOT do because if I see problems which will cause me warranty calls, unreasonable expectations that a "new box" will solve my airflow problems because a "comfort specialist" told me it would.:)

And I ALWAYS do the J,d,s to ensure i will have NO WARRANTY CALLS.

Here is an example from this month:

1. Oil furnace to heatpump conversion-the cheap bids did not address the tiny return the oil furnace had. Putting a new "heatpump box" where the "oil furnace box" would never have worked. but let me clarify-it would have worked for a short time untill it took out a compressor at 3 years or so and have been plagued with problems from low airflow. And doing it the correct way was significant $$$

HVAC systems are custom work-skills required-

Any company can put a box in to blow cold air-but it's really about getting the right air to the right places.
 
Save
I also have to say this because its saturday morning and I am watching TV.......

You will NEVER see me with an american flag bow-tie with a saw in my hand cutting a heatpump in half saying we are having a 1/2 price sale!!!!:gah:
 
Save
I'm in the same position as FLCat.

Our 1993 York 3.5 ton split system heat pump is getting expensive to maintain and because of our inadequate air return, under the house ducting and small floor registers (which was JUST made known to us AFTER three contractors had given us bids, with no Manual J/D calcs)...... we had to start over and seek new bids because the LAST contractor was up to speed and did Manual J/D calculations. Now we have to be sure that these NEW contractors will peek under the house, in the attic and do Manual J/D calcs.

Now to further complicate things, I had read about ductless split units. It sounded off-hand, these would eliminate new air return and new ducting under the house. One Mitsu contractor did ManJ and decided a 3 ton unit would suffice for our 2287 sq.ft. single level, 3 bed, 2bath and huge great room with kitchen, dining and living room, combined therein.

Another Mitsu dealer came by and said NO WAY would it work and will come up with a bid for a conventional heat pump with new air return and ducting.

Another Mitsu dealer will be here next week and from my description over the phone it sounded like a double Mitsu unit with more than 4 wall units, some ducted, some ductless, might work. But he will also see about a conventional heat pump for us. :gah:

We never had a heat pump before we moved here 5 years ago and so all this was a learning process for me. The more contractors that come here, the more I learn. Albeit, slowly, but learn nonetheless.

So, that is why there have been 6 licensed contractors here, another coming and I can see me calling another 2 or 3 after it is settled, once and for all, if I need a ductless or conventional heat pump.

I also tried to find a solution between #1 and #2 - using the logic that if I didn't seem have any ducting/airflow or system sizing issues previously (even temp throughout the house, system ran at reasonable rates for outside temps, electric bills were reasonable, no changes in windows or insulation and only a little more shade than previously (trees have grown), etc, etc) then I assumed that replacing the system with one of the same size and approximately the same quality should give me approximately the same results - *if* (very big if!) it was installed well/correctly.

[snip]

HVAC systems are custom work-skills required-

Any company can put a box in to blow cold air-but it's really about getting the right air to the right places.


What frustrates me is that with 3 of the 5 estimates I ultimately ended up with, they never even asked if I'd been happy with the results from the old system, or any other questions to determine if I might have issues that needed more work or professional evaluation - those three companies approached it simply as swapping out the old system for "a new box to blow cold air"... :(

Thanks for your input!

Hello folks, as the title states, just got it installed 3 hours ago.

I live in South Florida, temps are hot and HUMID! i purchased this home about a year and half ago, it had a 3 ton 12 year old A/H and a 2.5 ton 4 year old A/C mismatched size and brand total cooling area 1740 sq ft

i just had a Trane 3.5ton 4TEE3C04A1000A A/H, 4TTR5042E1000A A/C XR15

they did not install a XL900 T-stat, that i am looking to have added. i know it can do better take advantage of using the A/H to it's fullest potential.

the tech was not not very tech-savvy, he had to call someone to program the unit for start-up.

i am not pleased with the amount of force of air coming out of the vents. it's almost blowing the same amount as the old unit. i was hoping to really feel a difference in the amount of circulating throughout the house. i tried to watch as the tech did the programming, i also tried to to find a programming manual to see what the setting are and why. the blower is set to 50% and the CFM are set to 350. when he was talking to someone on the phone they did not ask my SQ FT or anything of the sort, only changing some settings to whatever for whatever reason. i asked the tech after it started up if the Blower can be set higher, he said if i want it to i can call they will up the CFM.

is this something simple enough for me to do with trial and error? (sorry if this falls into the DIY clause, yes i read the rules too :D )

where can i find a manual for these setting? (i have looked every online)

what is the proper line pressure? i looked at it just as they were disconnecting the gauges, and the low read approx @ 120, and the high was about @ 350 PSI, is this a correct pressure?

i hear the pressure line hissing (the gas expansion) , is this OK? its sound identical to my old one LOL
