Vent Cap - Reusable Air Vent Seals - Reviews and Testimonials - Pre-2014



I purchased the Total Home Pack and have been extremely pleased with its use. The time it saves is well worth the purchase price.

Thank You,

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.

Thanks! I think they’re great . . .  I have the technique down now.  Great time saver, and tape saver, and that equals to money!! I appreciate you shipping them so fast. . . we were able to perform 8 duct tests the next day.  I seriously doubt we would’ve been able to do so many without the Vent Caps! I will definitely refer you!

[The Squares] worked again flawlessly. Perfect man!  I need another 5 and a bag.  I’ve been using the [Vent Caps] too, and they work really really well, but the squares now work better.  I like the pole, the zippies, everything is working well.  They release well, they go on well, what else can I say.

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!

We love the vent cap system. . .  I honestly wouldn’t be doing this line of work if I had to tape everything off. Vent Cap is a must.

I can’t imagine having to tape each supply vent for testing.  Your vent caps save an incredible amount of time and work perfectly to seal each supply vent.  They are a quality product, and I am happy with the investment I made for my company.

Thanks again,

Thanks, Corey. I really appreciate the quick response.  These Vent Caps do work great and are real time-savers.

Your product has greatly increased productivity and efficiency for our testing.  The simple installation and use is far superior over other methods, including taping, that we have used in the past.  For any contractor or rater that is not using this product, it’s time to increase productivity and testing results.

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!

We love the Vent Cap system.  We get accurate test results without worrying about getting tape on paint.  Plus saving money on tape and less trash – it’s a win-win.  We were skeptical at first – but after trying our first set – we’re buying more.  They really 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.

The Southface EarthCraft Multifamily team has been using Vent Caps for about 6 months now. We have 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. 

Thanks, Corey.

Vent Cap Systems is a first rate company.  The service is fast and efficient and they are very helpful.  We highly recommend the Vent Caps to anyone wishing to seal registers for duct leakage testing.

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.

Thank you,

I’ve found that the Vent Cap Systems not only help me save time and money but they also provide a better seal than tape producing better duct test results.

Vent Caps Rock!  I’m never using pads or tape again.

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!

Thanks again,

 . . . we are cutting the amount of tape we use by 50% and therefore the Vent Caps are paying for themselves!  As well, we have received compliments in the field from builders that Vent Cap Systems makes our duct testing look more professional.

The first time I used the vent caps rather than the tape I knew I had made a wise investment. When I used the tool for the first time I was blown away. We can be more competitive on price because of the time and money saved by using vent caps.

This product is well suited for our production testing crew.  We use a number of clever methods to cover and seal vents and the Vent Caps are the easiest to use. We are a RESNET Provider and this will be our recommended method to perform Duct Blaster Testing.

We looked around and even tried to develop vent covers in-house. When we came across the vent caps developed by Vent Cap Systems they were exactly what we needed. The packaged system works great from hooks, to tighteners, and removers they all worked better than expected. I would highly recommend Vent Cap Systems for meeting your duct leakage testing needs.

These things work great! I’d rip paint off a ceiling or register itself at least once a week. Since I’ve gotten these, I haven’t had to worry about that. And they save me a lot of time!

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.

Vent Cap Systems enabled my company to service a multi-family/200 unit apartment complex in 8 working days, enabling my employees to be more efficient with time involved and more importantly, meeting a deadline! I would recommend the efficiency of Vent Cap Systems to everyone.

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.
