The choice is so wide that you may feel like a kid in the toy store – greedy and excited. But since we are adults, we need to make a wise choice and can’t just pick the shiniest and most colorful looking tool. So here is a review of the 5 best HVAC coil cleaning tools.
5 HVAC Coil Cleaning Tools
The pros and cons of the 5 HVAC coil cleaning tools are discussed below, along with their basic features. Hopefully, this information will help you choose your preferred tool well.
1. Garden Hose – Isn’t that wonderful? You can just use your regular garden hose to clean the AC coils. The biggest benefit is that most of us already own one and those who don’t can buy it really cheap. Your garden hose will also give you a good and plentiful supply of water as long as there is water in the tank. However, is the garden hose the best choice? Probably not and only because the pressure of water is quite low. If you try increasing the pressure by pressing the hose with your fingertips, you will only manage to get short spurts of it. These short bursts of pressure are not sufficient to get rid of caked impurities.
2. Pressure Washer – Overcoming the disadvantage of the garden hose is the pressure washer. This coil cleaning tool has a good amount of pressure to loosen the accumulated dirt and debris and gets rid of them. Its drawback is that it has just too much pressure. So much so that it can damage and bend the fins that cover the coils. The fins in air handlers are usually made of thin copper or aluminium. Being thin, water at high pressure can flatten them or crush them completely. One has to be extra careful while using a pressure washer to clean the coils in the HVAC unit.
3. Pump Sprayer – The coil cleaning chemical is filled inside a bottle or a small container, and pumping action expels it outside and onto the coils. This is why the apparatus is called a pump sprayer. When using strong chemicals using a pump sprayer is a good idea because you do not come in direct contact with the chemical itself. Nevertheless, a pump sprayer just gets half the job done. You still have to wipe away the chemical that was sprayed over the coils.
4. Aerosol Sprays – Using aerosol sprays is not a good idea mainly because they are not environment-friendly. But the fact that they are easily available and come cheap works in their favor. Most people also get taken in by their self-rinsing properties. Yet the truth is different. The chemical is sprayed on the coils, and it stays there until sufficient condensate has built upon the coils to drain it away. The harsh chemical stays on the coil far longer than necessary. It makes the coil more clogged until and unless the condensate helps drain it away. The coils are made of sensitive metals, so it is not advisable to expose them to strong chemicals for long periods of time.
5. CoilJetⓇ Coil Cleaning System – Saving the best for the last, a complete solution is the CoilJetⓇ cleaning system for coils. It is like a wonder tool because it cleans the coils effectively and efficiently. It works well even if you don’t have power or access to an unlimited supply of water.
