Why is My First Massachusett's Sheet Metal License Only For One Year?

Posted by: Randal Ripley Posted Date: 05/15/2011
I am sure by now many of you have received your Massachusett's Sheet Metal Licenses and were quite surprised to see that they would expire in 1-year and in some case a few months instead of the two-years we all thought.
 
I thought they were supposed to be for a two year term but if you read the procedures for license renewal you will see this is not so. See 3.02 below.
 
Also at this time there is no requirement for continuing education to renew your Massachusetts sheet metal license but the board does anticipate changing this at some time in the future. See 271 CMR 4.00 below.
 
The Coalition for Fair Licensing has sent a letter to the Sheet Metal Licensing Board requesting that licenses be good for a 2-year period starting February 19, 2011 when licensing was required state wide in Massachusetts.
 
They are requesting this on the basis of the license having no useful purpose until this date and the hardship of having to pay the renewal fee again so soon after paying the initial licensing fee. As of this writing there has been no response from the board.
 
Although all of us would like to see the board grant this request, I will believe it when I see it. Since the provision to give these initial one year licenses is in the regulations and would be a loss of a large amount of revenue to the state I don’t see this happening.
 
3.02: Procedures for Renewal of a License and Renewal of a Lapsed/Expired License
(1)   Requirements for Renewal of a License.
(a)   Licensees must renew their licenses every two years.  Each license originally issued to an individual shall be valid for a minimum of 12 months and shall expire on the 28th day of the licensee's birth month.  Each subsequent two-year renewal shall be on the anniversary of that date.
(b)   Individuals must submit to the Board, or its agent, a completed written or electronic renewal application and the required fees prior to the expiration date of the license; and
(c)   Individuals must fulfill and document, as specified by the Board, the satisfactory completion of continuing education requirements as specified in 271 CMR 4.00. 
271 CMR 4.00: Continuing Education
Licensed Sheet Metal Workers are encouraged to continue their expand knowledge by attending educational programs; however, no continuing education is currently required by the Board.  The Board anticipates adding such a requirement at some date in the future.  That will occur in a separately promulgated regulation change, and any requirements will be announced in future renewal documents.
 

Is the reputation of the Industry Really At Stake

Posted by: Randal Ripley Posted Date: 01/25/2011
When I read Butch Welsch’s column in the ACHRnews on December 27, 2010 expressing his dismay that manufacturer’s would be delivering 13 SEER R-22 condensers charged with dry nitrogen, all I could think of is the story of Chicken Little who was hit on the head by an acorn falling from a tree and immediately ran around screaming the sky is falling.
 
Mr. Welsch wanted to sound the alarm on what he sees as the manufacturer’s taking “…advantage of what I can only say is a loophole in the federal regulations and the Montreal Protocol” and went on to say “…I do know that the production and delivery of “dry charge” units, is definitely not within the intent of the original Montreal Protocol”… “However, then someone discovered that, by using the EXACT WORDING (emphasis mine) rather than the intent of the Montreal Protocol and federal regulations, they still could offer units that would utilize R-22 refrigerants”.
 
Imagine that, being upset that someone actually followed the law instead of trying to read the tea leaves. I don’t know about you but I get scared when people want to start discussing intent instead of what the law actually says.
 
What disturbs Mr. Welsch the most is what this situation says about the industry and do we really want to go back in time and be in the eyes of the public, what we were many years ago.
 
Here Comes the Boogie Man, Better Known as
 The Dreaded “Furnace Man”
 
Mr. Welsch claimed when he first got into the business in the early 1960’s He wasn’t real proud to say that he was a “furnace man” claiming that the industry that was mostly heating back then “had a very bad reputation”. Fly by night companies preyed on the public, knocking on doors and offering “free” furnace inspections and then would make sure there was something wrong with your furnace by the time they left even if not when they arrived.
 
Then through the efforts of the media who exposed these frauds, great leaders of the HVAC industry who promoted integrity, many years of contractors being honest with there customers and 30 years of word of mouth from consumer to consumer on contractor’s work quality the transition of contractors morphing from being the “heating man” to “professional HVAC contractors” took place.
 
Then after this set up Mr. Welsch finished with these comments, “I am concerned that this reversal of a major change from the improvement which we announced to the public is an indication that perhaps our industry is again being run by the “furnace man”. I believe that the manufacturer’s decisions to manufacture and deliver “dry charge” units is a result of pressure from contractors. Shame on us! “…Let’s not let the “free furnace” and “dry charge” units be a sign that we are willing to risk the image that so many have worked so hard to improve through the years.

In this one column Mr. Welsch found a way to use many of the factors used to control people and intimidate them into compliance:

 
  • Somehow cheating— Implied by not following the “intent” of the law.
 
  • Guilt--you must be a “furnace man” if you agree with the use of dry charge units.
 
  • Shame-- decisions to manufacture and deliver “dry charge” units is a result of pressure from contractors. Shame on us!
 
I am sure that contractors did pressure the manufacturer’s to make the dry charged R-22 condensers available because they wanted to be able to provide their customers an affordable option when the rules allowed it, not to plunge the industry back into the days of the “furnace man”.
 
Let’s look at a few facts about being allowed to use these condensers that Mr. Welsch failed to mention:
 
  1. They can only be used to replace existing R-22 condensing units (service applications) meaning complete new R-22 systems cannot be used in new construction or added to existing heating systems without A/C units.
 
  1. While R-22 supplies will dwindle by design of the Montreal Protocol, replacement R-22 refrigerants will be around as long as demand calls for it.
 
  1. I attended a webinar sponsored by the ACHRnews and the speaker who said he has personally spoken to people within the EPA who drafted this regulation and they told him it was drafted this way intentionally, that doesn’t sound like a loophole to me.
 
  1. This regulation was written this way for the very purpose of making it so homeowners would not have to replace a whole system over one component.
 
  1. This regulation does not allow one new R-22 SYSTEM to be added to the number of R-22 SYSTEMS, it simply allows the replacement of previously installed components.
 
  1. We all know if the EPA wanted to change this rule they would. Just look at how they are contemplating regulating CO2 emissions because of Cap N Trades failure to pass in Congress.
 
While these units are not for general use they like many other products in our industry fill a niche in the market. There are jobs that would require major construction and cost to remove the line set or air handler. Contrary to what all the magazines claim not everyone is willing to pay more for a heating or cooling system than they do for a car.
 
I am all for higher efficiency when “first cost to savings” makes it feasible but I also think that contractors should be able to provide consumers with replacement parts for their existing systems if the application calls for it.
 
I agree with Mr. Welsch that a certain percentage of contractors would be absolutely happy to go back to the days of R-22 A/C systems but this doesn’t make them dishonest, somehow cheating their customers or disgracing the industry.
 
Perhaps Mr. Welsch (I am emailing him a copy) could tell us how always telling the consumer they need a complete new system change out when you know all they really need is a condenser replacement isn’t being like the “furnace man”.

Hydro Electric Power: An Excellent source of Power Generation But Still Only Part of the Puzzle?

Posted by: Randal Ripley Posted Date: 12/07/2010
In an article that appeared in the Union leader business section on Sunday Nov. 6th, 2010 by Denis Paiste, a real and revealing look at Hydro-electric power generated here in NH was given.
 
In this article Public Service of New Hampshire (PSNH) Hydro manager Bob Gundersen said, “I feel like a farmer. I harvest the energy from the river.”
He went on to say, “I think hydro power is not just renewable but its reusable. We have several plants on the river, miles apart that use the same water to make electricity. It’s good clean power; it’s not emitting anything.”
 
Now there is a great concept, reusing the same water several times but what happens when the water necessary to generate the power is less? Remember hydro power depends on the rainfall and snow melting to provide the water necessary to turn the generators.
 
Gundersen claimed 2009 was a boon year for hydro electric generation at PSNH’s eight dams licensed by the Federal Energy Regulatory Commission. In fact according to the numbers report to this authority by PSNH it was the third highest output ever because of high rainfall but has fallen about a third to date this year from 312,211 megawatts from Jan.1 to Sept. 30, 2009 to 221,813 megawatt hours for the same time period this year (2010) due to a lack of rainfall over the past six months.
 
PSNH spokesman Martin Murray said, “If we look at how many megawatts of energy that was produced by our own units, that is energy that is the most economic that we have in our portfolio. If we did not have those, we would have to replace them with energy from elsewhere.”
 
I fully understand what Mr. Murray is stating here but when they go from over 300 thousand megawatt hours to just over 200 thousand megawatt hours you in fact do have to replace them with power generated elsewhere.
 
I want to make it very clear that I am all for wind, solar and hydro-electric power and want to see them developed to the fullest extent possible but we must also be aware of the shortcomings of these types of power that will result in less power generated to possible grid shutdowns when the wind doesn’t blow, the sun doesn’t shine or the rain and snow doesn’t fall.
 
Remember this famous Nancy Pelosi quote about health care but applies to many bills our leaders are passing nowadays: “But we have to pass the bill so you can find out what is in it, away from the fog of the controversy.”  Well I say our desire to “Go Green” and produce efficient, clean energy cannot and does not mean we have to blindly pass legislation without knowing the cost and/or affect these renewable energies can have or totally eliminate fossil fuel and/or nuclear generated power.
 
A wise energy policy will have us utilizing multiple forms of electrical generation that can supply a steady stream of reliable power with some extra capacity for peek usage times. The old tried & true saying “not to put all of your eggs in one basket” applies here just as it does to so many other things in life.

Cap & Trade Options: Wind, Solar And Does Anyone Really Think Nuclear is an Option

Posted by: Randal Ripley Posted Date: 10/13/2010
I am sure by now most of you have heard of the American Clean Energy Security Act of 2009 that has passed the House but not the Senate. That doesn’t sound familiar? Maybe you know it by one of its other names “Waxman Markey” or “Cap & Trade”.
 
The bill requires a 17% reduction in carbon dioxide & other greenhouse gas emissions from the 2005 levels from burning methane (natural gas), oil and coal by 2020 and an 80% reduction by 2050. Research by the Cato Institute shows the 2050 level of carbon-based energy would be equivalent to our level of use in 1867. Yes, 1867.
 
The goal of the bill is to substitute electrical energy produced by carbon based fuels with wind, solar, Geo thermal & some nuclear produced electricity and in fact wants an electrical provider that supplies over 4 million MWH to produce 20% of its electricity from renewable resources by 2020.
 
According to the US Dept of Energy, the last nuclear reactor built was the "River Bend" plant in Louisiana. Its construction began in March of 1977 and went online in 1986. A second reactor on that site was cancelled due to opposition. For some reason Seabrook, NH is coming to my mind right now.
 
The last plant to begin commercial operation is the "Watts Bar" plant in Tennessee, which came online in 1996.  This plant started construction on 2 reactors in 1973 but the 2nd reactor construction was halted in 1988 and started again in 2007 with an expected online date in 2013.
 
Responding to the criticism of the bill by some opponents that it does not sufficiently advocate for the use of nuclear power, House of Representative staffers wrote “…the bill provides various types of financial support to build clean energy generation sources, including nuclear; and that the EPA study indicated that twice as many nuclear plants would be built if the law passed versus the status quo”.
 
Does that mean twice as many as in previous history? It certainly can’t mean twice as many ground breakings on new nuclear plants as the past 30 odd years because 0 X 0 still equals zero.
 
In my June 14, 2010 Industry Buzz column titled “Not in My Back Yard” I wrote about the problem of everyone being for wind & solar energy until it is going to be placed in their back yard and then the opposition & court challenges come. As you can see Nuclear power has the same problem.
 
Now to the biggest of the many problems I have with this legislation. If we are going to reduce carbon emissions to the levels the government would like in this legislation and replace it with wind & solar for the most part what are we going to do when the wind doesn’t blow or the sun doesn’t shine?
 
Electricity must be provided in a steady stream and then supplemented during peak demand times. Wind & solar cannot do this because of the reasons cited in the previous paragraph.
If wind and solar stand alone a substantial reduction in electrical generation could be expected during periods of bad weather conditions leading to possible grid shutdowns.
 
So how do we provide power during these times, do we fully back up wind & solar with conventional plants? Remember that coal and natural gas are a no-no, so that leaves nuclear power if we can ever get one built and what will be the total cost including legal defense fees after all the lawsuits and legislative battles?
 
If we have to back up wind and power because of weather with nuclear generated power I can’t understand how anyone can say that this bill will not cost us a fortune, Everyone of these types of energy generation are very costly.
 
The Congressional Budget Office (CBO) study in June of 2009 said “the bill would be roughly deficit-neutral for the government over the next decade” and “that the tax burden on individual households would be limited”.
 
What they didn’t say though according to a study by The Heritage Foundation who estimates that by 2035 this energy bill alone will increase the cost of power by 90% because most of the cost to consumers isn’t because of taxes but from the cost associated with replacing coal, gas or oil generated power with expensive wind & solar generation and whatever back-up it requires.

Duct Blaster Testing—Here’s What I Know

Posted by: Randal Ripley Posted Date: 09/14/2010

According to the Energy Conservatory there is more than a million miles of duct work in U.S. homes. Industry experts estimate that more than two-thirds of them are leaky which can significantly increase energy bills, reduce equipment efficiency and even potentially add to indoor air quality problems, justifying sealing or repair.

There is only one way to tell if you have thoroughly sealed your duct work and that is to perform a Duct Blaster Test. I have fielded many calls from technicians on the topic of the new energy code requirement for Duct Blaster testing to verify the tightness (sealing) of residential duct work.
 
To be honest with you I really didn’t know anything about the testing procedure or how it was going to be enforced so I did some digging around (on the internet & with inspectors) for information and now know a lot more about how the test is done but still not a whole lot about how it will be enforced by inspectors in varies towns but here is what I know.
 
The residential energy code of 2009 which has been adopted by the State of New Hampshire states in section 403.2.2. Sealing (mandatory). All ducts, air handlers, filter boxes and building cavities used as ducts shall be sealed. Joints and seams shall comply with section M1601.4.1 of the International Residential Code.
 
The Duct Blaster test is the test used to verify that ducts are not leaking beyond a certain amount of pressure with all ducts & register boots sealed. If the air handler & duct work are within the conditioned space this is the one exception in the code for not doing the test.
 
The Duct Blaster test and the blower Door Test are two procedures that are often confused with each other because of their similarity of purpose but they perform two different functions. The Duct Blaster Test is used to test the tightness of residential duct systems while the Blower Door Test is used to check the leakage of residential buildings.
 
A duct blaster combines a small fan and a pressure gauge to pressurize a house’s duct system and accurately measure air leakage of the ductwork. This test is similar to a pressure test of a plumbing system. Duct leakage can increase heating & cooling cost over 30% and contribute to comfort, health and safety problems.
 
There are two choices of Duct blaster test and either one can be used according to the 2009 energy code:
 
  1. Total Leakage (rough in)—the duct blaster is connected to the air handler to pressurize the taped-over duct system to 25 Pascal’s (0.1 in WC) pressure differential. This is about the pressure that an HVAC system normally experiences. The blower door is not used for this test. The Total CFM amount of duct leakage is determined.
 
  1. Leakage to the outdoors (post construction)—Since some duct leakage usually occurs within the conditioned space and is not necessarily bad from an energy standpoint, an additional duct test is performed to measure duct leakage To Outside. For this test, the blower door test is used to pressurize the house to 25 Pascal’s and the duct blaster pressurizes the ductwork to the same level. All duct leakage measured is to the outside, or unconditioned space, and represents heating or cooling energy loss.
 
I sent a few emails and made some phone calls to inspectors and most were just as in the dark as I was about this whole thing. One asked me if I could put a sample mock-up together of what the test would look like and present it to a group of building inspectors but I wasn’t prepared to do that at the time.
 
Many are asking who is doing this kind of testing and what towns are enforcing this rule already. If you know answers to either of these questions please let me know by phone 603-889-0100 or randal@totalairsupply.com .
 
This rule also has the potential for HVAC companies to add another source of revenue. Those who get in now will have a leg up on those who jump in later.
 
For those of you who are thinking they will just do their own testing, great thought but 3rd party testing will be required although nothing can stop you from setting up a separate company under your business (making it a third party) and then performing test on your HVAC Company’s jobs.
 
This article just covers some basics of Duct Blaster testing but if you would like to learn the subject in depth, I have put up a bunch of video presentations & articles for you to learn much more.
 
If you read this in a non-electronic format the website for the articles & videos is http://www.totalairsupply.com/library.aspx.
 
Until next time, Add to your box of knowledge daily, soon it will have many reference cards.
