The Energy Conservatory® | The DG-1000 Is Coming . . . Still

DG-1000 Digital Gauge by The Energy Conservatory®The Energy Conservatory®, manufacturer of the Minneapolis Duct Blaster®, has updated the release date of their newest gauge, the DG-1000.  They will now have them to view at February trade shows.  With the release of Retrotec's DM32 Digital Gauge months ago, TEC's response has been long anticipated.  I offered up my thoughts, and lack of enthusiasm toward their interface, here almost 3 months ago.  It doesn't look like I was alone in my assessment.  The most recent update states,

"Programming of the gauge continues with an eye to the user interface, home screen, global settings, connectivity of the various ports, update capabilities and overall measurement performance."

I think this is the right choice for them, it's always hard to push back release dates but coming out with something, that not's quite what it could be, is worse.  I'm looking forward to hearing the reviews when they come out, but with a reported 10 more weeks for mold manufacturing alone, I'll have to keep waiting. . .

Hi Corey,
We have pushed out the release date of the DG-1000 a few times to allow our team at TEC to create a high-quality product that meets our customers’ expectations for technology and user experience. When this gauge is released, it will have capabilities that no other gauge on the market has, such as the ability to add apps through online updates in the future. We’ll have the DG-1000 available for people to use at the ACI New York Regional Home Performance Conference in February. Hope to see you there!

Hi Jose, the DG-1000 will be available for purchase very soon. Please check for updates. If you have further questions, send me an email at

Thank you!

Vent Cap Systems on

As of today, they’re still planning on a release in February. They’ve added some videos that are pretty damn goofy, but of high production quality. Not a lot of details still. . .

Stay tuned!

Your Duct Leakage Testing Could Take Less Time!

As an energy auditor or HVAC professional, you know just how time-consuming taping up each duct vent can be during a leakage test. What if there was an easier way that would allow you to spend less time taping, so you can go about your day more quickly and easily?

Vent Cap Systems Save Time

Compared with traditional vent tape where you have to climb up on a ladder and deal with a sticky mess each and every time, Vent Cap Systems allows you to spend less than 30 seconds sealing and unsealing a vent.

That’s only half a minute per vent! At such a quick pace, you could seal and unseal 30 registers in only 15 minutes. When was the last time you spent only 15 minutes taping a house?

How Vent Caps Work

So just what makes Vent Cap Systems so quick and easy to use? Unlike tape where you have to clamber up a ladder, have appropriately sized pieces of tape ready, place them on and keep your fingers crossed that it holds a seal, Vent Caps make the process smoother. Here’s what sealing vent registers looks like with Vent Caps:

1. Set the Hook

Raise the hook (with the remote attachment tool) with a pole and attach to the register. This won’t require a ladder unless ceilings are incredibly high.

2. Raise Vent Cap

Using the pole lift the Vent Cap along the string, until it’s located just under the register.

3. Release Vent Cap

Finally, release the Vent Cap by placing it firmly over the duct register.

To unseal any vents, you simply have to reverse the process, by first releasing and lowering down the Vent Cap and finally unhooking the system.

Start Saving Time on Your Duct Leakage Tests Today

With Vent Cap Systems, your days of using time-consuming grill tape are over. You won’t have to waste time, money, or carry a ladder all around. Don’t spend any more time messing with unwieldy ladders and sticky, wasteful tape. You can try Vent Cap Systems risk-free with a 30-day money back guarantee and a full one-year warranty, so there’s nothing to lose and only time and savings to gain.

Tired of Throwing Away Tons of Vent Tape?

Duct leakage tests and energy audits used to require a lot of tape, but now there’s a better solution. Instead of having to buy large amounts of tape and waste time with messy register sealing, only to throw the tape away, Vent Cap Systems offers a reusable and durable alternative.

While tape was a practical solution for years, there’s now an easier way to seal registers during your duct leakage tests or energy audits. Vent caps from Vent Cap Systems are reusable, durable, and easy to use. 

Instead of having to use a ladder to seal every register, you can quickly seal and unseal with a vent cap and a pole attachment. On average, you’ll only spend about half a minute sealing and unsealing a vent. Just imagine how long it would take you to tape that same register!

Using Vent Caps Instead of Tape

Vent caps make preparing for and cleaning up after your duct leakage tests quick and simple. The process only involves placing the hook on the register via a pole. Then, you’ll raise the vent cap towards the register along the string. Finally, you’ll release the vent cap where it firmly seals the register.

When you’re done with the testing, you’ll just release the vent cap, lower it down towards yourself, and unhook the system. Everything then packs away and will be ready for your next test. You definitely won’t miss throwing out all that tape! By saving tape and time, you’ll be able to fit in more tests into your day without having to worry about whether you have enough tape to get you through.

Stop Using Tape for Your Duct Leakage Tests!

Tape used to be the only feasible solution for duct leakage tests, but now with Vent Cap Systems, you’ll be able to give up the tape for good. With sturdy and reusable vent caps, you won’t have to use sticky and messy tape to seal vent registers. Over time, you’ll save money while also significantly reducing the amount of time you spend conducting each test. 

You’ve wasted enough tape, so start preserving resources and your time. Trying Vent Cap Systems is completely risk-free. When you purchase vent caps, you’ll receive a 30-day money back guarantee and a total one-year warranty, so there’s nothing to lose — except the tape!

Building Performance Institute (BPI) Lists Reusable Air Vent Covers

I'm proud to announce that Vent Cap Systems has been approved by The Building Performance Institute™ (BPI) for inclusion as a BPI Listed Product.  BPI Listed Products are matched to specific home performance testing standards and other criterion.   Coming on the heels of the USPTO's recent issuance of our patent is certainly welcome news after over five years in the business.  Both are further recognition that Vent Caps are both novel, functional, and necessary tools for anyone doing duct leakage testing.

Tapes Not Sticking To Low VOC Paints?

Home Performance contractors keep telling me that the new Low VOC (volatile organic Painter's Tape compound) paints that some builders are using is making it hard to set up a Duct Blaster® or DucTester™.  It's hard enough setting up for a duct leakage test without then having to worry if the tape is going to stay where you put it.  That's one of the attributes of Vent Caps Systems that makes them invaluable for sealing duct systems.  Once they're up, they're up.  Vent Caps™ seal air vents whether they're dripping in condensation, freshly painted, or dirty as the dickens and they make the test results reliable and reproducible.  Energy Auditors and HERS Raters both have quality assurance providers double checking test results.  Having them match not only keep the auditor or rater out of the dog house, but consistent results lend credence to the home performance industry.

Have you had trouble with the tape sticking to these new paints?  Please comment below if this has been an issue for you in the field.

Michigan Energy Code Mandates Duct Leakage Testing

According to the Department of Energy, Michigan will be the fifth state to adopt the 2015 International Energy Conservation Code (IECC), with "amendments, deletions, and additions deemed necessary for use in Michigan."  For now, this only affects new residential construction and significant renovations, without requiring unaltered building systems to comply.  Michigan's new energy code requires less than 4 ACH and <4% duct leakage per 100 sf. of conditioned space with testing, "conducted by an approved third party."

As expected a RESNET HERS® Index will be accepted to show compliance.  The minimum Energy Rating Index scores are:

What is a duct blaster test?

You've probably heard the term but may not know the details. . .  A Duct Blaster® is actually a registered trademark belonging to The Energy Conservatory™ for their marquee fan/manometer system, aka The Minneapolis Duct Blaster®.  The Energy Conservatory™ has been diligent, at least in my experience, to defend their trademark from "genericide", however, IMHO it's likely to go the way of Kleenex, Aspirin, Escalator - all formerly trademarked product names that became too descriptive of the product losing the owners their protections.  It's an interesting catch-22 for product manufacturers, you work to build a brand name, only to then defend it once it finally "becomes a household name."  Can you believe "Heroin" was once a trademarked product?!

The test people are actually referring to is called Duct Leakage Testing which is now mandated all across the country, in one form or another, and the backbone of any worthwhile residential energy audit.  It's the pressurized testing of a home's ducted air conditioning system for diagnostic purposes.  The average house in the US reportedly leaks 25% or more - of the air just conditioned - outside the "building envelope".  Duct Leakage Testing, and subsequent repairs, have the highest return on investment of any energy efficiency upgrade and are saving countless millions annually.
