It's time to stop the use of R404A

R404A is one of the most widely used refrigerants in New Zealand, there's a good chance you use it in your cooling system. It has a high global warming potential, which also makes it one of the most expensive refrigerants to use or replace. 

There are better alternatives that won't cost the earth. 

A refrigerant is a substance used in all refrigeration and air conditioning systems to transfer heat from one location to another. The use of refrigerants in refrigeration systems is essential for modern production, however, refrigerants can have a significant impact on the environment.

DTS Service-Man customers get a 100% discount* on refrigerant upgrades. 


Find out more about Service-Man

Service-Man customers will receive a 100% discount for each kg of R404A we replace with R449A. That's a saving of $3,700 per jug.

R449A is more environmentally friendly and can also provide greater cooling capacity and energy efficiency. Plus, it's widely available and can be easily retrofitted into existing refrigeration equipment.

There may be some systems that require extra work, but these will be discussed with you before any work takes place. 

We believe this is important.

That's why anyone who isn’t a DTS Service-Man customer will still get a 50% discount on refrigerant upgrades.

However, it's not too late to sign up for our annual Service-Man plan. You'll get a 100% discount and you can be sure your equipment is in top working condition. You'll also receive a 5% discount off the recommended retail price on a range of DTS products and services.

It is estimated that 90% of refrigerants used in NZ eventually leak into the atmosphere. 

We need to break the use cycle of R404A.

When we collect the R404A we consolidate it and it is sent to an authorised destruction facility. It gets treated in a high-temperature reactor to break the chemical bonds and is then transformed into Sodium Fluoride or Calcium Fluoride (as you find in toothpaste).



  • The 100% discount is only for R449A and is only available to DTS Service-Man Customers. This offer is subject to availability.

  • All other R404A customers will receive a 50% discount on R449A.
