Grill mask tape can rip the paint off of the face of the grill when retrotite logotaken off.  I learned this the hard way after removing the mask on many grills in a tall ceiling on a job a long way from home.  I had to buy and install the covers that the paint came off.  These Vent Cap System covers are very easy to install, seal tightly, and won’t damage the vent cover.  Very well made should stand up to years of use. At the cost of vent tape they will pay themselves back on every job, thanks for a great product…
Thank you Corey,

Love my Vent Caps! Once they’re up, they’re up. No need for extra masking tape to seal problem edges, trouble with adhering to dirty vent covers, paint pulling off, etc. Less waste and ordering of tape is a huge bonus!

Before we got the Vent Cap System I don’t know how we survived without them.  We have done about 350 duct seals since getting them and they save us at least 30 minutes per house.  That’s about 175 hours of labor I didn’t have to pay for.  They have paid for themselves time and time again.  They are easy to use, my guys don’t have to carry ladders, and my “tape bill” is almost non-existent.  Thanks Corey for making a great product!

Vent Cap Systems provides an excellent alternative to sealing duct system vents with tape. The tape method was taking at least an hour to complete in an average house. The time it takes me with the Vent Cap System was reduced to just 20 minutes or less. I’m so happy with my investment, and will proudly endorse Corey Breed @ Vent Cap Systems. His product does exactly what he said they would and they are helping me be more profitable too.

I have used your duct covers for the last month.  There is no comparison in the amount of time  saved per project using your Vent Caps  vs. using tape or a combination of tape and press n seal to seal vents.  I would recommend your product to any energy rater who is interested in minimizing their time on any site visit.
Best to you and your endeavors,

Hello Corey,

I cannot say enough great things about Vent Cap Systems.  It has really transformed my days in the field.  The efficiency of body movement is much more in line with the business.  The psychological perks are the real highlight.  I do mostly large multifamily projects where there is a load of repetition.  Just knowing I will not be going up and down a step stool a thousand times changes my psychosocial outlook of each project.  Thank you for your efforts.

Much appreciated!

We have been in business since 2005 and have always used Glad Press–N –Seal and Painters Tape. I buy in large amounts so our cost is very low but we still were going thru about $1,000.00 every month and a half in supplies. My Raters got very fast with this application. I decided to try your Vent Caps with one set. They took a little time to get used to. Some of my Raters still used their ladder to put the pans up but after buying more sets all of my raters are using them with the pole from the ground. They work great when you have items like beds and pianos that we can’t move. Our cost for Press–N–Seal and Painters tape has gone down about 75%. I have already paid for all of the caps that we have bought with the supplies savings. Would highly recommend these to any person doing Duct Testing.

Thanks for convincing me to try Vent Caps.

Once you try them you will not be disappointed.

I first heard about the Vent Cap System through an older gentleman that had gotten into energy testing of new homes.  I myself had started doing the energy testing but was using tape.  I am getting older and going up and down a ladder up to 50 times in one house, 150 to 200 times a day was starting to wear on my knees.   Once I tried the Vent Cap System I was sold and bought a bunch the very next day.  Now I go up a ladder only twice in each house and it has nothing to do with the Vent Cap System, just hooking up the duct blaster to the return air grill.

In my first month of use I had a few problems and found I had five broken caps.  I wrote and email hoping that they would have a good support department and low and behold I got a call within an hour of writing an email and had my new caps shipped to me immediately.

This is a great system and anyone thinking or looking at this system should just buy them and try them as you will not be disappointed.

Thanks Corey, keep up the good work

Since receiving our first set of Vent Caps my lead HERS Rater (Sam) has used these caps on several jobs, both residential and commercial.  In testing out this product the Rater did a number of duct tests where he used both the “old method” of applying Press-N-Seal” and taping the registers, and then retesting the same job using Vent Caps. The differences in leakage results were negligible. Sam also expressed his appreciation in eliminating most of his “high ladder” ventures.

From an owner’s perspective, the ability to eliminate most of the Press-N-Seal, and painter’s tape previously purchased in large quantities was a key benefit in our decision to switch to Vent Caps.

Based upon our combined analysis I was happy today to place an additional order for Vent Caps, and I would recommend these vent caps to ANY HVAC or inspection company.

Hey Corey
We ordered the total home pack system a few weeks ago.  What an awesome product!  Ill be honest, I was a little skeptical at first, but once I used it for the first time and got used to it, it was so much easier than taping ducts.  Not only does it save time, it saves me from sweating profusely after going up and down a ladder for 45 minutes!
Anyway we love you product and we hope to order more soon as we continue to grow the business.

If I had to put a formula together to determine the value of a Vent Cap System it would go like this:
Our crews perform anywhere from 2-5 duct blasters a day each.  Vent Cap Systems shaved off about 10-15 mins on each test and made them more accurate.  Do the math on that and then add in the savings from cutting the cost of register tape by 80%.  Then add in the time wasted, costs associated with, and frustration involved in tearing off paint when you’re ready to go home.  Then divide that by the square root of one.  That should do it.
Thanks Vent Cap Systems!

I love these Vent Caps!  They are much simpler than the tape and they work better than other vent cover systems that I’ve used.  After one job with practice, they are so easy to install and take down that I don’t want to ever go back to anything else.  I estimate they have improved my time for preparing for the duct testing by at least 30%.  Thanks for developing these and I look forward to any other tools you may develop to make our job of auditing easier.

Testing ducts used to be our least-favorite part of any inspection.  Lugging ladders or using extension poles around a home to cover registers with tape took forever, especially in large custom homes with high ceilings!  Shelling out cash multiple times a month to keep enough register tape on hand seemed like a huge waste of money.   We were always on the lookout for a better way…

Vent Cap Systems has been the duct sealing “game-changer” our company was searching for!  The covers are a snap to install and remove.  We’ve cut out testing time by more than 30% and we never have to worry about getting on a ladder or damaging freshly painted registers in homes!  We’re also saving hundreds of dollars every quarter and reducing those huge wads of tape going into the dumpster after only one use.

After 2 years using Vent Caps, we couldn’t imagine ever going back to the old way of doing things.  Keep innovating and keep up the good work!

With the adoption of the 2009 IECC and the uptick of new construction in northern Nevada, I have been busy performing the required pressure tests for compliance. It was wasteful using the tape and took longer than I wanted to place the tape and then take it dowm. After a couple of days to learn the placement and removal of the Vent Caps, I’m very pleased with the time and monetary savings. They have definitely boosted my production.

found using them saves a lot of time and money over using tape, which is very important when doing six
to nine tests per day on a fairly regular basis. The Pole RAT keeps us from having to lug around a ladder
as well. Overall, we have been very pleased with the Vent Cap system and have incorporated it into our
SOP. Please keep us apprised of new products as you roll them out.

The Vent Cap System has been a complete game-changer for me. . . I am MUCH faster in my testing times. The biggie too is the confidence: with the Vent Caps, I can trust that the supply vents are really being sealed vs. questioning whether or not my tape is sticking or not — plus the possibility of taking off paint when I used to do the tape thing. The RAT is awesome, I’ve used it for covering vents on 16′ ceilings.

Great job,

I’ve been using Vent Caps for a while now and have gotten pretty good at taking them on and off using the Remote Attachment Tool. It is faster than tape but what I like best is that it is so much safer. With Vent Cap, I can seal return grills in high ceilings without even touching a ladder, much less climbing to the top of one.

I have used the caps on several jobs since receiving them. They are great!  We used to have to try and balance ourselves on ladders while duct taping the supply vents in the ceilings and on the walls. With these vent caps, it saves time and is much safer for my employees. Another benefit of these caps is; no more paint peeling from the walls and/or ceilings due the tape that we used to use to cover vents. Great job! I would recommend these vent caps to ANY HVAC or inspection company.

I have been very happy with the Vent Cap Systems. Using the provided tool on a extension pole has helped me get to several ducts that would have been near impossible any other way, or very dangerous, time consuming and costly at the least. I have even been able to seal up ducts that are 20+’ above my head that would have been a pain with the traditional taping process. Those alone have almost made my investment worth it! I have had a great experience with them, as I know they have saved me time, money and the ever concerning issue of paint removal from registers. I look forward to them outlasting me!

I love this product! The covers seal so tight and quick.  It cuts our testing time way down and no more standing on a ladder craning my neck around while I tape off the supply registers.  We had one of our employees on a test with us just before I ordered the vent cap system that overtaped a register and when he went to pull the tape he pulled the paper right off the drywall of a brand new house.  Not the way you want your customers to remember you.  These covers make testing fool proof.  This is the best addition to a Building Analyst’s tool box since infrared.  Thanks.

We use VentCaps at DuctTesters, Inc. for several reasons.   They cut our costs by as much as 66% on tape – we were generating a lot of tape waste during our verifications and we had a difficult time justifying [it].  With Vent Caps, we not only use far less tape but have cut our paint peels from ceilings and walls on homes significantly.  Homeowners appreciate this consideration and our clients appreciate it when there are no mistakes.

Our tests are as accurate or better, than with tape.  Vent Caps are quick and easy to use, cost less and provide a professional image that gives DuctTesters, Inc. an edge.  We use them and we like them.

The ladder is my worst enemy right now. I almost took a fall yesterday. . . You need to highlight how much money a company could save in a work related accident. A typical house has 30 register, that’s 60 trips up and down a ladder. I do at least a couple homes a day. There is a good chance one day, one of those trips up a ladder could be a nasty one without your vent cap extension tool!

We have started using the vent caps and love them. One of best things about it is saving us from all of the grills we replace annually because the tape has pulled off the paint. They also seal  better than the tape on ceiling with that heavy popcorn texture. The crews also love the fact that it saves them time. It’s been a win-win business decision for us.

 I work with home performance auditors across the U.S.  Most of my students are not in areas where the local incentive program requires a ductblaster test.  When the home performance auditor came to my home in Texas he included a ductblaster test.  I was amazed by how quickly he and his helper were able to set up my 3,400 square foot house for the test.  The Vent Cap product made it fast, simple, and effective – even with the vaulted ceilings in my home.  From my homeowner perspective, the preparation was quick, clean and very professional.  As a home performance expert who has done ductblaster tests with plastic sheeting and tape, I am extremely impressed with the Vent Cap product.  I will recommend this to all of the home performance testing companies I work with.

In our business we conduct thorough and accurate residential energy audits.  We have been able to do this because of quality tools like Vent Cap Systems.  In the past we were using tape to seal the A/C returns which were time consuming during setup and in some cases damaging.  Since our switch to Vent Cap Systems we have noticed time, money, and quality savings.  Advanced Energy Auditors would recommend Vent Cap Systems to any business in the industry looking to better their service and savings on the bottom line.

We’re glad we found out about ‘Vent Caps’.  Our HERS raters said the vent caps saved several minutes off the time it takes to perform on-site verification.  This method was easier and more efficient than the previous method we used.  Saving time is saving money.  This was a great investment for us.

I used the vent caps yesterday, November 17th on a home that had 13 supply registers. It took me less than 30 minutes to install all the Vent Caps and get ready to start the duct blasting. I know before with tape, it took a lot of time and it was messy. Since this was a new home with a newly painted interior, it was important not to have any areas where tape may make a mark on the painted surface or actually take off some paint.

My new Vent Caps provide me with a quick and professional way of doing business. I want to stress professional! Looking up on the ceiling and not seeing supply registers with tape spread all over makes a big impression on the homeowner or builder. Taking them down didn’t take any time at all. By the time I climbed the ladder, they were down.

Thanks again,
