Look out, trainers- Carrier has a new certification program called Energy Experts. Still finding out what they're teaching, but it looks like a faction apart from BPI and RESNET.



  • Hello David,

    I always enjoy your posts,

    Please note my comment was restricted to "existing houses", where as you correctly point out, none of the inputs to the load calculation model are known values without "extensive testing". Anyone who has done this testing knows the inputs can have wide variances, for example ACH could easily vary by 1/2 an air change, system losses could be 10-35%, who knows?

    So all the guys doing the "calculations" without the testing are simply making the model "come out" and not calculating anything at all, that is a fact. There is no difference between making it come out and simply guessing the size, just 6 guesses vs one. I must admit to finding humor in listening to guys tell me about how accurate they do their loads,baloney, how silly. Also, some of these guys make the poor customer watch this act as part of their sales pitch. I believe no one should have to watch a contractor type on a computer unless they are medicated with quaaludes, or as part of a prison sentence.

    So on old houses, we game the load, to give a piece of paper with little numbers on it to an inspector or utility guy, who does not know what the little numbers mean, to snag a rebate, payed for by our children or our neighbors, all to save energy, only it is well documented that "proper sizing" does not save any energy at all. And then we expect to sit at the adult table?

    As for new houses, Again I am sure I will burn in hell for this as well. We sold production builders as many as 10,000 carrier units at a time, sometimes fighting over .60 cents per unit. The builders would let us sit in the Lobby listening as they tortured the
    Manufacturer ahead of us, stripping them of any dignity and hearing them cry out as their margins were squeezed. We did terrible things to get the business, we don't talk about them now.

    All the same floor plans get the same size AC system and the same ductwork system regardless of orientation, with a Furnace "sized" to deliver the CFM required (usually big enough to heat 3 houses), all the ductwork was in unconditioned spaces, built to "code" and that means if we had 1 penny more in cost than we needed we were not competitive. If a helicopter flew over our job site we would lose our labor for three days.So if I (or anyone who had to compete for this business) designed the HVAC on your new home, your AC was too big at least 75% of the time, your furnace was big enough to heat your house and the house on either side, and the ductwork was screwed up, but it was done in perfect compliance with the code and the calculation procedure.

    I find it amusing to listen to the True Believers tell me they need to take the
    three ring circus of testing in to each home in an old subdivision. After 3 houses you should figure it out, they either suck, or suck worse. If they are any better than that, I did my job wrong.

    The residential load procedure is a dumbed down version of the full calculation with the time variable removed, because we were assumed to be to stupid to understand the concept of time variant loads, and to uneducated to to do the math.

    Best to you,

  • Tell me this. In Texas, the average AC guys say, I checked the static pressure and it was fine. Isn't it true, you can have a very very leaky duct system but still get your static pressure.? In fact, isn't it sometimes easier to get the static pressure reading when the system IS leaky? In that case, people just heat and cool their attics.
  • That is completely true. The more you seal the ductwork, the higher your static pressure goes. That is why anytime you seal ductwork, you need to recheck the static pressure AFTER the sealing is done. We are an Aeroseal contractor and the majority of our aeroseal quotes include adding returns or increasing trunk sizes. If the static pressure is at .45 but they have 25% duct leakage, you know that the static is going to be out of range after the seal is done. Even sadder, some duct systems are out of range even before we seal.
  • I find it amazing that, after an industry insider such as PJ drops such revealing information as he has, that people like Larry & Jolene can start talking about an entirely different subject. This thread was about how the new Carrier 360 program is going to be good for Home Performance, and how they are going to "own it". After reading PJ's last post, does anyone think that industry is going to be a good thing for Home Performance? I say an industry of "true believers" are better suited to take the reigns. The true believers at least are starting out with the honest premise of starting with the notion that Home Performance should bring about real & cost effective energy & comfort solutions to homeowners, and from there, how to make it profitable for contractors. Big corporations & their contractors start out with the notion of how can we make more profit under the guise of Home Performance without really having to deliver on the promise. Look at Efficiency Last, I mean Efficiency First, and their latest push to take cost effectiveness out of the equation. That is a natural result of letting big companies & their contractors take control of Home Performance. If this were a presidential election for Home Performance I would vote Ted Kidd as being president and I would be glad to be one of his cabinet members.

    Which is a great argument for why contractors should not just sell boxes. Refrigeration diagnostics don't mean much if airflow isn't right, and airflow diagnostics don't mean much if the ducts are leaky. Seal the ducts ->> verify proper airflow at the coil ->> verify balance ->> verify the charge.

    Too many folks claiming to be home comfort or home performance specialists don't follow "whole building" approach, or worse, they don't understand system interactions or how various building components and improvement measures affect one another.

    Didn't seem that way but I'll take your word for it.

    So let's talk about existing homes. You seem to be dismissing "extensive testing" as if it's a bad thing. Testing the infiltration and duct leakage would only add a couple hundred to the cost of a typical (existing home) project, which in most cases would be more than made up for in smaller equipment. In cases where testing reveals things are worse than status quo assumptions, a "home comfort" contractor should be all over that. What's the point installing high priced modulating equipment without first addressing the all the defects in the duct system and envelope?

    you wrote:
    "The residential load procedure is a dumbed down version of the full calculation with the time variable removed"

    Dumbed down as it is, the 8th edition of Manual J (which by the way, includes time variant window loads) is pretty darn accurate based on cycle timing I've done, and research done by others. If anything, it overstates cooling loads by roughly 10%, so there's no justification for gaming the inputs if the designer bothers to find out what the correct inputs are.

    Why not try to be part of the solution rather than perpetuating the worst the industry has to offer?
  • David,

    Thank you for your comments,

    Please don't take my word for anything, I have been a professional liar most of my life.

    Instead, please re read my post, I said "Without extensive testing all the inputs to a load "Calculation" on an existing house are just guesses".

    I know more HVAC contractors than anyone on the planet, and I have never, ever, even heard of anyone doing any testing on an HVAC sales call, ever.So by discussing testing as it relates to Load Calcs on existing houses, you might as well be counting unicorns.It never happens.

    As I said, Every guy tells me their loads are "pretty dam accurate", only they are all different, kinda funny how that could be. No one I know, can put the cost of testing into a job, to size a unit prior to a sale, to "find out what the correct inputs are" and stay in business for more than a week.

    I would hope you would want to know more about me and the projects I am involved with prior to making a determination as to weather I am "part of the solution" or not. I am sure, I know a bit more about HVAC and HP modeling and Load calculation software than most. My customers include almost all the very top companies in HVAC and HP, the leaders in the field, and we have by far the largest software development budget of any team in either business. Our systems our provided free to contractors and we currently have over 15,000 users doing about 3000 IECC 2012 compliant load calculations every day. Our free Auditor software is by far the most elegant and accurate tool around for HP. Would you consider these projects part of the solution?

    BTW the statement on your website "Oversized equipment is less efficient, thus increases operating costs" is not true in fact in many cases over sizing a heat pump will lower your balance point, use less electric backup, and reduce costs.

    We have 3 different distributors in Tucson, including the largest HVAC distribution company in the world, if you would like to learn a little more, before beating me up any further, I will happily get you hooked up and wait for your Christmas Card.

    Wow, flaming thread!

    I think Carrier's plan is with the best of intentions. Their equipment is brilliantly designed and when properly implemented saves a tremendous amount of energy and provides mind blowing comfort. They don't want to have their name dragged through the mud because "Op Cost" savings don't realize, heat exchangers crack, or ECM's burn up due to issues beyond their control ("Yeah, Mrs. Smith, been having problems with these Carrier fans..." - ESP 1.1 - what's that?). So educating "Comprehensive" is most definitely in their best interest.

    The problem is market transformation. Shifting from product based sales to solutions based sales is tremendously complex, and requires 180 degree shift in orientation.

    It also requires tools. Sales pipelines get geometrically fatter and longer, so instead of managing this week's leads you have to manage the last 8 weeks leads. And instead of just proposing furnaces, you need to manage a suite of improvement recommendations.

    I think it requires ERP or CRM like Salesforce or Zoho, built specifically for BPI or RESNET, and provided as part of these organizations services. Right now they only provide the science and NO sales approach training.

    Without retraining and providing tools to make the new approach work is it any surprise Sales fight tooth and nail against changing from tried and true? Is it any surprise design and contract precede diagnostics and modelling?

    Phil, your writing is a gas. Please write a book about that stuff!?

    Tips, thanks for your continued support of results transparency and accountability, and Rick Gerardi's contractor registry. http://bit.ly/gerardihpregistry
  • Carrier has a professional sales video that focuses on heating and cooling equipment and ductwork. I don't see an energy audit there.

    A few glaring oversights in Carrier video and website. No mention of how they address leaky houses --just duct leaks. Would they use rigid board, spray foam, densepack? Would they subcontract that work? (Oh, I forgot their website says its "simple.") No mention of common air leak locations in the "envelope" (other than in ducts). Brief mention of leaky "hollow walls", followed by two IR images-- neither showing a bypass leak in a wall.

    Beyond the market transformation problem Ted mentions, I see a culture problem here for the HVAC industry. HVAC culture involves wanting to work close to the equipment in the basement, backyard or attic. HVAC culture does not involve wanting to suit up and work in areas where lots of protective gear is needed, or work in very cramped quarters, or in any of the dirty, filthy places good energy auditors and insulation contractors must venture routinely.

    You're wrong about that. A small but growing number of HVAC contractors have embraced the whole-house approach. Also, the use of duct blasters and blower doors is already mandatory in a growing number of states, ahead of the 2012 IECC.

    you wrote:
    "No one I know, can put the cost of testing into a job, to size a unit prior to a sale, to "find out what the correct inputs are" and stay in business for more than a week."

    Of course not! The testing and design happens after the contract is signed. The dealer just needs to include a caveat that the proposed equipment size may change based on diagnostics and whatever action the customer takes to correct defects found. Another business model is to charge for diagnostics (most car repair shops do this), possibly with a credit toward further work.

    The equipment proposals clients share with me tend to vary by thousands of dollars for a given home. What I find interesting is that the highest bidders are not necessarily the companies I would recommend, especially when it comes to geo. My point is adding $1000 or so for diagnostic testing and proper design isn't necessarily a deal killer.

    Look Phil, I realize this is not where the industry at large has been or is currently. All I'm saying is that the arguments you throw up against proper design and diagnostics are looking backwards, not forward.

    "I would hope you would want to know more about me and the projects I am involved with prior to making a determination as to weather I am "part of the solution" or not."

    Whatever I know about you is based on the positions you take in these forums. You have every opportunity to represent yourself through your comments. Sounds like there's a disconnect between what you do and what you say. It's almost as if you're making rash statements you really don't believe just to stir up the dust.

    My bad. Mea culpa.
  • Ok Dave, Lets review

    We agree that no one does any testing or design until a contract is signed. So, all the load calculations done prior to that on old houses are useless (but required by code) other than from a theatrical perspective.

    Dan is correct that the true believers are under siege by big business and Cheryl is also correct that insulation and air sealing are not in the HVAC' companies wheelhouse. Yet,
    Orangutan Air Conditioning in Phoenix, will change out more systems by their first coffee break on a Monday, than a true believer will do in a year.

    The business model of going house to house, with your blower door, smoke bombs, laser beams, x ray vision glasses, doing 4 hr science projects can only exist in a communist economy supported by other peoples money. As we discussed, any "test in" is a total waste of money in tract house neighborhoods,we know they suck.

    When the AARP money or your neighbor's rate payer money dries up, the true
    believers go back in the ground like the 17 year locust. Their model is not sustainable, they will need to compromise a bit. The big production HP companies I know will no longer hire True Believers as they feel they are to far gone in terms of understanding the need make a profit to be of any use.

    Since the HVAC company has the customer base, and continuing income, it might be a good start to be a bit less condescending and as my mother says "Holier than Thou". Unfortunately, good high quality insulation companies that show up on time, with shirts on, sober,and don't lear at the customer's daughter are very hard to find. When you can get the HVAC company hooked with the Insulator as a sub contractor you can start to move the needle on real energy savings in a high volume, production way. Houses are insulated and sealed, ductwork is sealed and insulated, new smaller havoc systems are installed,
    and our customers are comfortable.

    And the true believers move back in with their parents.


  • Cheryl,

    The 7 and a half minute video is a sales piece to customers not to auditors. There is more info to a customer in customer language, no industry jargon which we all tend to get into our conversations with customers, than I usually see elsewhere.

    Customers don't need to know the difference between dense pack, rigid foam, spray, and all else. A home performance contractor in my mind, goes in on the sales call and does the diagnosis, gives the customer a prioritized sheet showing repairs, costs, returns, etc, and then tries to close the deal. Then when the work is done goes back and verifies readings anything that was worked on.

    The details will be different for every home. The home in the video needed a whole lot of everything but really didn't need a new box. They had open crawls paces to the basement and to the house, uninsulated attic hatch and missing insulation, air bypasses from the crawlspace through electrical outlets, bypass ducts in the attic that were very leaky.

    When home performance contractor is on site for diagnostics, have the customer run the equipment and show what is a good reading and what is a bad reading. Tell them you will fix it, prove it and have customer for life.

    This is a stretch for many HVAC contractors because they can't or don't take basic static pressure tests.

  • from Frank....."A home performance contractor in my mind, goes in on the sales call and does the diagnosis, gives the customer a prioritized sheet showing repairs, costs, returns, etc, and then tries to close the deal." Ok, I am in agreement here. This is where it gets a little sketchy. From what source does this contractor obtain that "prioritized sheet"? Is it a software program? (almost never with AC guys) His own knowledge? I won't even comment on that. Or is it his pocket book? I see radiant barrier, insulation, all kinds of things coming from this as they miss the mark again.....It's about duct sealing, air infiltration, fenestration. ventilation. Unfortunately, most of the AC companies, which is 98% of the ones I have surveyed, do not like doing duct work to begin with. Why on earth would they want to start testing it for it's leakage. God forbid, they might actually have to do the "right thing". We teach the "right way". Not a lot of them follow it. We teach the "right thing". If you're doing the right thing, chances are, you are doing it the right way. Ask yourself next time, are you doing the right thing? I love this industry, but how to you purge it when it's time?
  • Larry,

    Yes, I did skip where the contractor has had training on energy audit software that develops the prioritized list. Doesn't mean they are auditors just they use the same program. This idea is being developed through a number of avenues. RESNET is working with ACCA on their Home Contractor Program, or whatever it is called.

    This is not for everyone. Techs that don't take basic static pressure readings are not going to have a blower door and duct leakage tester. Techs that place the end of tube connected to a U tube gauge to measure flow through a register are not going to do this. There are lots of qualified trainers that teach this stuff.

    Old adage about horse and water here.

  • Similar to one, you can lead a man to congress, but you can't make him think?
  • I question the focus of the Carrier 360° program. Love their equipment, but they are a manufacturer with business interests. From their website: "There are three basic fundamentals that support Home Performance. Each one is critical to the overall comfort and energy efficiency of your home." They define these three basic fundamentals as HVAC, air filtration/distribution, and the home envelope. I don't disagree with these three categories...what I worry about is how they visually depict the importance of these categories. Take a look at there website here: http://www.myhomeenergyexperts.com/about.php and you will see my issue. HVAC is shown as 50% of their solution, air filtration/distribution shows up at roughly ~30%, and home envelope is around ~20%. I would likely rate these categories in the exact inverse of what Carrier has, but that is just one person's opinion.
  • Hmmmm, ok, call me picky, anal, whatever, it's 2012......Note: from carrier website Srikanth.......And, you can feel confident with their Carrier heting and cooling 100% Satisfaction Guarantee along with their local knowledge and expertise. If they can't spell it, do you really think they can deliver it? This is all a bunch of corporate BS, guys sitting behind desks, plugging in numbers, never been in an attic, and only work off the data they have been given. Where did they get that data? ........Here is my story. I have inspected over 1500 AC systems in the last 24 months or so. All the inspections were QA inspected by a Resnet QAD. I can guarantee you that less than 20% of them had that low (20%) of duct leakage. (per the carrier website) Remember, according to DOE, 20% leaking in the attic is perfectly acceptable! NOT! The real story is that upwards of 80-90% of them had duct leakage of 35-50% and some even more. Why? Oh, did I forget to tell you that between 40-60% had been changed out (box only) by an AC company? The bottom line is this. Always has been and always will be. AC guys hate changing ducts. It doesn't make them any money. They would rather push a starter capacitor, blower motor, or heat exchanger...or whatever else they can sell and get in and out within about 2 hours. It's their business model. Are there good guys out there? Yes, but it's a selective group. Funny thing, here in Texas, the last 3-5 years....we see more and more AC guys getting into spray-on radiant barrier.....the most ambiguous product on the market. Also, they push attic insulation. I'm ok with that, but don't you think you should fix the ducts FIRST, before you go spraying their attic with chemicals and insulation? Really, is it about profit or comfort? I think we know the answer. Recently, we have been informed by the HVAC advisory board in Texas that it's ILLEGAL for an energy rater to perform an audit. You heard me. Illegal! We aren't even allowed to take a filter out without violating the state law. I suggest you all tune in to the TDLR website on November 14. You will see what ACCA is up to in Texas. Hopefully, it's not coming to your town. If it does, your business model is going to change rapidly. Imagine this, starting tomorrow, you are no longer allowed to perform a third party duct test and make a suggestion via REMRATE. Oh wait, there is no enforcement! Wake up people. Call it like it is.I love the guys on here who speak the truth. Now don't dazzle me with all your brilliance...this is pretty simple stuff.....it's NOT rocket science, but it is building science. I would bet my farm that if you issued a Resnet Rater test to every AC guy in the country, the failure rate would be well over 75% +. Ok, sound off..............I'm ready to hear your retorts. Don't confuse my passion with anything other than what it is....it's doing the right thing, the right way I'm not angry or upset, I am just tired of people protecting AC guys with excuses. There is no excuse why an ACCA standard 12 is out and no one enforces it, most AC guys have never read it. People change when the pain to change is less than the pain to stay the same. Are we there yet?
  • Amen Larry. The problem with us "true believers" is that we are not organized and we don't have the money big business has. Even the organizations that are supposed to be devoted to energy efficiency is controlled by big business. As PJ said, and as you are witnessing in your neck of the woods, big business is taking over and that is just the way it is. Allen Jackson's song "The little man" comes to mind.
  • Where we are organized we have a say. Join Efficiency First and your local chapter if there is one. If there is not a local chapter, start one. It starts there.
  • Riiiiiiiight, it starts there. Just for once, don't you think we have enough organizations trying to "FIX" the problem? That IS the problem. Too many chiefs, not enough indians. I respect and support most every organization in this field, including EF. Just remember, just because I don't agree with you doesn't mean I disrespect you. If people would just do the "right thing", the problems in the world would be moving in a different direction. It's just that simple. Tooley says is best.. there are several ways we do things. You can do the right thing, the wrong way, the wrong thing the right way, etc etc. Problem is......in the end....it's all about just doing the right thing, the right way, in order! We can't even get an industry to agree on how to size an AC. So what is the right way and the right thing to do? Join another organization? It starts with YOU, not them. Remember, "we" together are "them". Now go vote for the lesser of two evils and let's do something good.
  • Welcome to the Market, folks! It's messy out here. However, the market is where this is going to happen unless we have a central command and control. Until earlier this week, though, when the East Coast got a taste of what rising sea levels mean, there has been pretty close to zero political will to get things done on the scale needed. And I have little confidence that Congress will move away from its circular firing squad and put a constructive energy policy in place.

    And in the meantime, I heartily applaud Carrier and what they are trying to accomplish with the 360 program. I daresay it isn't perfect--although that also explains the businesses of everyone in this group! Carrier is taking good first steps in the right direction. We all need to keep taking steps in the right direction, learning from our mistakes and improving. I'm not suggesting one can't take a critical view. However, there is little value in a holier-than-thou view which pays no heed to how to actually deliver home performance to the market. This isn't about big v. little as much as it's about finding something that works. And by works, I mean something that millions, not thousands, of homeowners are paying for. We're not there yet, and we need to be!
  • Larry,

    Just making sure that this statement that you wrote is correct that it is "ILLEGAL for an energy rater to perform an audit". What then is the definition of an energy rater in Texas? Who is authorized to perform an audit in Texas? What is the definition of an audit in Texas? Who is working on the state level to help them see the light? What about Txas Hero and other groups?

    As for Carrier, of course their motive is to make money. Why else do people own and run businesses? Yes there can be altruistic reasons but if they don't make money to sustain their lives through their business then they already have money. At least Carrier is trying to elevate the industry. Who else is?

    Most HVAC companies continue to practice what they have been taught which is put the box in, connect the lines, see that don't leak, check to see if any cool air is coming out somewhere and leave. It's is true everywhere in the country. Even break off companies, unless this new owner breaks off to be completely different than his/her predecessor will continue to the same type of work as before.

    Why do builders have HVAC companies put A/C systems in the attic? Why do HVAC companies agree to it? "Cuz that's the way we always dun it."

    All this home performance stuff is new. Audits are new. This is change and people don't like change. Anybody familiar with adoption cycle for new products? This is going to be long process.

    Sorry for wandering.

  • Discussion is good, doing is better, doing it right is best. So much of what we as auditors and raters discover is the result of things not being built to the best quality standard i.e. should not we expect a new duct system to be sealed well below even 6% leakage?. Of course we cannot expect perfection but we can expect the best that can be done. A great deal of energy would be saved if more education, training and best of all apprenticeing could get done at the tradesman level. At least here in California so many in the field of energy auditing/rating (or trying to stay in the field) have been saying, "The only persons making any money at it are the trainers and training orginizations". Of course we need training, continuing education and training updates. I believe a whole lot more focus needs to be put on somehow (open to suggestions) convincing the everyday John and Jane of the value of energy upgrades both in new and retrofit construction so there is a viable market on which the technology can feed and be fed. Then concentrate on training the workforce to be truly "performance" contractors. Most everyone wants to and needs to save money. We need to convince them how saving energy, short term and long term can do that and help provide a rasonable financing method (I vote for PACE).
  • One if the improvements being included in the 360 program, and some of you have mentioned, is the duct sealing by Aeroseal. Do any of you have recent experience with the new Generation 2 equipment and results. (Apparently the first "generation" had some disappointments but the newer version is supposed to be "improved". If you have knowledge of this latest set up and performance achievements - please share. Thanks in advance.
  • I think that part of the problem with getting the big manufacturers and HVAC companies involved is that this stuff is difficult and complicated. Not from the building science side of it (at least for us that do it all the time) but trying to incorporate it into a business model that hinges on marking up products a great deal for basically installing the metal boxes. This is especially easy to understand in the existing market where the contractors try to touch as little of the existing ductwork as possible but ducting and distribution really does get short shrift in the new home market as well - especially in custom homes where duct layouts don't get replicated from home to home.
    I wish there was a way where home performance could be treated as a separate trade and a complete building analysis gets done BEFORE anything gets done to the home. It's a shame that it gets folded in with a big retailer's attempt to sell a product. Biased? I think that is a real possibility, especially if the Carrier guys don't recommend anything outside of the things that only directly relate to the testing they do.
    IMO, the best thing for consumers is to have independent, comprehensive testing done up front so they can be somewhat informed when the contractors come-a-calling.
    I'd also like to see personal jet packs in every driveway too.
  • Mark,

    I'm seeing total energy savings from 30-70%. Sometime that's just from replacing 84% with 95% equipment.

    Do you think ability of homeowners to go SEE these results might take this from anicdotal to incredibly compelling? From "sure, but that wouldn't happen for me" to "holy cow, I can't live with how much I'm wasting, where do I sign?"

    Check this out, I think it's a sign we might be able to solve this: http://bit.ly/gainsvillegreen
  • Michael, I have a contractor friend here who has bought that equipment and been doing Aeroseal for about a year or so. He can knock down the leakage better than anyone I have seen. We do all his test ins and test outs. I typically see upwards of 50-75% reductions. Is it the absolute answer? No, but it does help especially with hard pipe and/or wall cavity returns. It's limitations are 5/8 I believe he said. Also, it's labor intensive, but I think average cost is around $500+ and he sells them for $2000 a system. It typically takes 1-2 days to complete a project.I can put you in touch if you want to talk to him.
  • I am also for jet packs in every driveway Mark. To infinity and beyond!!!!!
  • Aeroseal is fantastic. Testing, improvement, and verification all in one step. I have a client in Baltimore who couldn't believe how it changed comfort and humidity in his home, which prompted me to go to the factory and see it for myself. I'll post videos for those interested.

    Downside is hard to sell. Big overhead. 50k equipment plus truck & 2-3 man crew. You need $20-30k gross revenue a month to justify, and $2000 per job for an improvement unheard of and unbeliever in by most.

    I think this is a solution that requires govt incentive to build momentum. My client only paid 50% of the cost, and wouldn't have done it without it.
