How to Recharge a Dehumidifier
In the old days, you could by an air conditioner recharging kit. Hook the hoses to the air conditioner or dehumidifier (or refrigerator) and follow the instructions. Easy!
Today, your dehumidifier may still use R-22. If so, due to strict environmental regulations, you’ll need to check with an air conditioner repair service.
They may be able to help you, but they may not. (Yes, they need a permit for this. Be sure they have one.)
A panel or sticker on it may tell you which coolant your dehumidifier uses. Or, the manufacturer’s date may give you an idea. If the dehumidifier was made before 1995, it’s likely to require R-22.
If you own a newer dehumidifier, it may use a more environmentally-friendly coolant. (If you bought your dehumidifier after January 2010, it’s almost certain to use something other than R-22.)
New dehumidifiers usually run on R-410A,ralph lauren. That’s often called Puron.
Puron is one of the best alternatives to R-22. It’s inexpensive. So far, it has fewer problems that some other “green” coolants. Puron still causes some ozone problems, because it’s methane base. However, it better than anything else you can buy now.
Puron (or R-410A) runs at a much higher pressure than R-22 did.
So can’t just replace your R-22 coolant with R-410A. The valves and gaskets may not hold, and if your coolant leaks out you’re back to square one.
Generally, it’s safer and cheaper to replace your dehumidifier with a new one that’s already set up to use R-410A (Puron).
I recommend only one dehumidifier, no matter what your needs. It can handle damp basements. It runs economically. You can set the humidity level you want, and it turn itself off when it reaches that level no wasted electricity!
It also one of the quietest dehumidifiers and it has top ratings and customer reviews at Amazon. (It regularly on Amazon sellers list.)
