Convenient and Easy to Use: The no-rinse formula is a major plus. I simply turned off the unit, sprayed the foam according to the instructions, and let it work its magic. No need for extensive prep work or messy cleanup, just a quick and convenient process.
Effective Cleaning: The foam visibly dissolved dirt, grime, and dust on the coil. After letting it sit for the recommended time, I could see a noticeable difference in the coil's cleanliness. My unit seems to be running more efficiently since the cleaning.
Pleasant Scent: While I did choose to follow up with a light rinse using a spray bottle, I appreciate that the product has a mild lemon scent. This is preferable to the harsh chemical odors often associated with cleaners.
Reviewed in the United States on January 16, 2024
I still wanted to clean the coils since I already had the covers off. The spray was easy to use and the can works well at an angle.
I allowed the foam to work for about 15 minutes and just about all of the debris dripped away.
Even though this is a "no rinse" cleaner, I still used a water bottle sprayer filled with distilled water to rinse off the coils.
Be sure to wear gloves, protective eye wear and a mask. This might have a very pleasant scent, but you still shouldn't be breathing it in.
If you have a Bryant furnace, the outer cover is held in place by four 5/16" screws. They might be hidden under some caulk / sealant that you have to scrape off. The inner "A" shaped coil covers are also held in place by 5/16" screws.
Don't forget to turn off the A/C system, unplug the furnace and/or turn off the circuit breaker before you open up the unit.
Overall, I'm very pleased with this purchase. I could have just used half of the can, but I used the entire can just to make sure every inch of the "N" coil was sparkling clean.
I don't think I'll need to do this procedure again for at least a few years since our A/C filters are ceiling mounted and I change the two filters every month.
