About Us



"Applying natural refrigerants in HVAC is or soon will be as logical as it is in your fridge at home, at your food manufacturer, or in your supermarket.”

PLEASE NOTE:  ecofreeez is sold as ef-22A outside the USA only 

EcoFreeez provides natural hydrocarbon refrigerants. We are committed to combat climate change and ozone layer depletion by substituting harmful fluorinated gases ("F-gases", such as CFCs, HCFCs and HFCs) with natural refrigerants with a focus on their point-of-sale cooling applications. These substances can be used as cooling agents (heat transfer medium) in refrigerators and air conditioners, don't harm the ozone layer and have no or negligible climate impact.


In the 1970s, scientists discovered the dangerous impact Chlorofluorocarbons (CFCs) have in the Earth's atmosphere. CFCs were used as foam blowing agents, refrigerants and solvents. It was found that they destroy the ozone layer, so that aggressive UV-B radiation can reach directly the Earth's surface causing genetic damage in the cells of people, plants and animals.

Therefore, in 1987, an international treaty was concluded at Montreal, Canada (the so called Montreal Protocol on Substances that Deplete the Ozone Layer), to prevent the ozone layer from further destruction and begin the phase-out of the use of CFCs and other Ozone Depleting Substances (ODS) like Hydrochlorofluorocarbons (HCFCs).


Hydrochlorofluorocarbons (HCFCs) and Hydrofluorocarbons (HFCs) are fluorinated gases (F-gases) and are widely used in many commercial refrigeration applications, such as beverage coolers, vending machines, ice cream freezers, open deck coolers and freezers used in supermarkets. HCFCs are ozone depleters and will be phased out under the Montreal Protocol. HFCs are as greenhouse gases controlled under the Kyoto Protocol.

In the refrigerant sector, two ozone-friendly replacement technologies are available: climate harmful fluorinated refrigerants (HFCs) and climate-friendly natural refrigerants. If HFCs will replace HCFCs, the climate benefits of the Montreal Protocol will be lost in a short period of time.

Therefore, EcoFreeez has decided to support climate-friendly technology and go for natural refrigerants.


1) I agree, and life gets more difficult every day. Regulations and more regulations. I am a semi-retired Engineer and had a PE license in several states before I retired. Although my background by education is electrical, my experience covered other fields as was necessary over the years. This included considerable construction, mechanical, and HVAC.

I got fascinated by the refrigerant issues several years ago when I stumbled upon some articles on hydrocarbon refrigerants. That is what lead me to you. One thing that is appalling is the lack of real skills and knowledge with the average heat and air companies. They really do not know the basics of their product. All they want to do is sell new equipment for high dollars.

The major experiments are with my home Heat pump which is about 25 years old, a 42,000 btu unit. By my calculations, I have increased the EER from about 8 to 10 by using  ecofreeez and a few other small changes. I am in process of a few major changes, and will let you know the results. It might help you and others.

2) I have been using ecofreeez in a Carrier Model 38TK036310 air conditioner (three ton unit manufactured in 1990) since Aug 15, 2006. Upon conversion from R-22, the power consumption to the compressor unit reduced from 16.9 Amps @230 VAC to 13.0 Amps @ 230 VAC (this includes the cooling fan which consumes 1.4 Amps @230 VAC).

The high side pressure reduced from 257 PSI to 200 PSI (ambient temperature was 96 deg F when measured) with a noticeable reduction in the noise level. The outlet temperature was 10 degrees colder than with R-22 and consistently holds below 55 Degrees F even when the ambient temperature has reached 104 Degrees F.

The Carrier air conditioning unit is now 19 years old and I expect to replace it in the not too distant future. Carrier's new energy efficient air conditioning units use R-410A as a refrigerant and consequently are not being considered as a potential replacement.

Could you advise of any Original Equipment Manufacturers (OEMs) that are supplying new air conditioner units with EE-22a or one of your other refrigerants ?

Thank you for your every consideration,

3) Hi Guys !

Just wanted to tell you, I evacuated the 27,000 btu window ac I have, put in 1 can of ecofreeez, put in a second can, started the unit, started putting in the third can. I had a suction side pressure of about 76 psi. The ambient temp was 84 deg F. The output air temp, using a bimetal thermometer (of which I checked the cal. of), was 60 deg. As it started going lower, I let out some of the gas, bringing the suction press to 72 psi.

I reinstalled the ac into it's through the wall slot, and let it run. As the temp in the room went down, I checked to find the room temp at around 72 degrees, and the ac output temp at 50 degrees. After sunset, room temp down now to 69 degrees, and ac output to 45 degrees !! This stuff is unreal !!

The pressure at suction when I first charged it was, as I said 72 psi, as the unit was running. When the compressor turned off, the pressure rose tom 350+ psi. As the compressor restarted later, it returned to 72 psi.

If this unit got much colder, I could have hung meat in my living room !! Just thought you'd like to hear of my experience. Thanks for a good product ...........

4) Unbelievable!!! I filled up a 3 Ton and a 5 Ton Split System with EcoFreeze and they were both fully charged with only about half of what it would take of the original R-22 refrigerant.

Pressures and temperatures in both high side and low side were perfect.

And yes I will be re-ordering soon.

Thanks a bunch !!
