Review: Works very well - Very nice product that does what is says it will do. I wish the refill liquid were more reasonably priced!
Review: It did the job! - Very simple and convenient to use because you don’t have to measure out the cleaning solution with water. The downside to me is that the cleaning gun is a bit expensive. In my case, the condenser hadn’t been cleaned in 16 years so if I had used aerosol spray cleaner and garden hose alone, the cost of the number spray cans needed would have exceeded what I paid to clean the condenser.

## Questions & Answers

**Q: What are the mix ratios for this sprayer?  My coil cleaner says to mix 1 part cleaner to 3 parts water.  Is there a 1:3 ratio setting?**
A: Yes there is , you will find that it will  coincide with all the ratios on yor cleaner

**Q: What is the spray setting for this sprayer when you want 1 part cleaner to 4 parts water?**
A: It has 5 settings you set with dial (plus off): A/3:1, B/4:1, C/6:1, D/9:1, E/10:1

**Q: are Replacement tips available?**
A: Not that I've seen but there are cheaper versions of this kit which have the same foaming spray tip. You can also check for car wash foamers-they may have some parts.

**Q: Can I use this to spray chemical on my house siding that is 2 stories high?  If NO, why not?**
A: It may not spray that high. I have excellent water pressure and it will only reach about 15 feet. Shooting straight up, no way to make it all the way to the top of the second floor.

### ⭐⭐⭐⭐⭐ NU CALGON 4774-0 Coil Gun Sprayer
*by 9***8 on May 12, 2023*

I purchased a new HVAC system a couple years ago and didn’t think about servicing the unit because of its age. However, I researched that the unit should be serviced annually. So after further researching I found that the coils on the condenser can easy be damaged if done incorrectly. I came across this product. Many professionals use this so it makes sense to use it myself. Prior to applying the chemicals, I did as instructed and washed as much as possible the dirt away so the chemicals can breakdown all the buildup in the coils. I failed to get the sprayer in action as I was focusing on getting this done correctly using the chemicals to clean the coils. I do like the foaming action this sprayer uses and I don’t need to worry about mixing with water as it does this using the proper setting on the sprayer. After use, I thoroughly washed the sprayer from any left over chemicals so it can be used next time. For me it was all about proper cleaning and reusing the sprayer rather than purchasing coil cleaning spray cans. I feel with this method I would get better results. I am happy with how the condenser was cleaned and looking at the muddy dirt on the ground, I think it was worth the investment.
