Nos mudamos a un apartamento más grande. Note un olor muy desagradable saliendo del A/C. Busqué en Google “remover malos olores de aire acondicionado”. Note este producto, llamado Ductaid. Lo use de acuerdo a las instrucciones. Funciona de maravilla. Muy satisfecha. Lo recomiendo.”

I have 2 AC central systems in my residence So I purchased 2 cans. The instructions card was easy to follow. I treated both units and the results were excellent. I have two dogs in our home and not only did it freshen the air but it has had no impact on our dogs. I will share my experience with my friends, for sure.

If you’ve ever thought, “You know what my house needs? A nauseatingly strong perfume scent that makes me question my life choices,” then boy, do I have the product for you! I bought Ductaid thinking it would freshen up my HVAC system and make my house smell nice. Instead, it launched an olfactory assault so potent that even my dog refused to come inside. Imagine someone broke into your house and sprayed every bad perfume from a discount rack—then cranked up the heat to bake the scent into every fiber of your being. That’s Ductaid in a nutshell. The smell is like a mix between a floral candle factory explosion and cheap cologne from a gas station. It doesn’t fade, oh no, it intensifies—as if it feeds off your despair. My house now smells like it’s constantly hosting a middle school dance mixed with martial arts exposition. Nice - right? To make matters worse, this wasn’t just a scent problem. Whatever Ductaid did to my ducts actually made my HVAC system less efficient. Now my vents are a superhighway of misery, spreading the stench room by room. Save yourself, your family, your pets, your nose, and possibly your neighbors nose. Ductaid isn’t a product—it’s a cruel prank disguised as home improvement. I would give it zero stars if I could, but here we are. I guess I’ll just go live outside now. Final verdict: 1 star for sheer audacity to make a product so awful!

Update: 9/28/23 Below will be the original review. I wanted to give an update. The manufacturer reached out to me which was great and amazing customer service, they offered an apology and also offered a refund and in stead I asked for them to send me a new one. Which they did, and I was excited to see if there was going to be a difference in what was my complaint and issue with it and there was. The trigger was fixed and there was no leak when I sprayed it. Now, my new issue is the scent was weaker than the first one I had purchased. It sprayed better, but this new can felt lighter then the original. The first can that I recieved which had issues had a stronger scent that really filled the room and also filled the AC vents. The new one barley did the same. I'm still not giving up on this company, they have an amazing product, they just need to really focus on fixing the consistency of it. _----_--------------------------------------------------- Original review: I see many people complaining about the price, and I will never understand why anyone complains about price after paying the price! This product works, but there are issues. I bought a house that is a hundred years old, although renovated, it still has that old house smell. I became tired of using plug in fresheners and decided to give this a try. First, read the instructions carefully. When using in the HVAC system, you must have the fan on and not the heat or AC on. I used a little in the HVAC system and the scent spread through the entire system. Although the scent didn't last long, it did make the air coming from the HVAC system seem fresher and cleaner. I then used it in the rooms that had the strongest scent of old house, I sprayed the corners of the walls, I sprayed the center of the room including the light fixtures. Now, the second I started spraying it, it was dripping liquid. And when you turn it to the side to spray it at an angle, the air escapes more than the liquid. So this can is best to be used upright. Now, I only got to use half of the can and all of the air was used and there was a lot of liquid left in the can and it just stopped spraying. I believe in this product because it really did work, a week later and the smell of old house was much lighter, makes me think what would have happened if I was able to use the entire can. So with that said, the sprayer is the issue completely, there is no durability in the scent as it dissipated in less than an hour, but for some reason I don't think it's meant to last long. This product does indeed work, they just need to fix the flaw that the can and sprayer has. I would give them a chance when they have a new and improved sprayer.

We bought a 4 pack Duct Aid for my 2900 square foot home. Not to mention that this is a 2 story residence. I have 2 kids that think there are professional cooks. The constant burning of food is a tradition in this home. I use to buy room Fresheners by the box, no kidding. Not to mentioned the extra exercise I am getting from waking to the second floor to deodorize the entire house. I use the product in my HVAC according to the instructions. It got rid of the smell with one can. What a game changer. No more walking up and down to get rid of the burning smells. The only thing I miss is my exercise. So I joined the gym. I definitely recommend Duct Aid. From a happy customer.

This seems to be much more like an air freshener. I tried a test spray in my basement and a small spritz caused the whole basement to smell of baby powder/musk perfume. I'm not a fan of the smell. Technically the musty smell in my basement has temporarily been masked by this perfumed odor, but I don't like it.

This product works! Even though I couldn’t get spray tab to lock (per instructions) in order dispense all the product, I sprayed vent great with some of product & followed rest of the instructions. Four to five minutes later, bad odor was gone from home! Despite the spray tab not locking as instructed, fortunately I still have some product left if/when house needs refreshing again.

I recently moved into a 2-bedroom condo with a serious smell coming out of my vents. My AC guy recommended to have my system treated for mold odors for $599. I used 1 can of this product, followed the instructions and the issue was solved without spending a lot of money.
