What's an Air Conditioning Dry Charge?

April 01, 2015

Over the past several years, both the U.S. and Canadian governments have instructed that all producers of air conditioning equipment phase out production of the refrigerant R-22 (Freon) or Hydrochlorofluorocarbons (HCFCs). These refrigerants have been typically used in air conditioners and heat pumps for many decades. The R-22 and HCFC mandates are suppose to have the HVAC industry move to a more earth friendly refrigerant with a technical code R410A. R410A has been shown to be safer for the environment.

In late 2010 most air conditioning companies began manufacturing Air Conditioning and Heat Pump units, without adding refrigerant at the factory. These units are more commonly called “dry charged units”. They can legally be sold and installed allowing the HVAC contractor to charge the unit in the field with R22. R22 is still legal for AC repair or service for a few more years. The reason for these Dry Charged Units is to provide the greater the Niagara Region area a more simple and relatively inexpensive replacement option for central air conditioners and heat pumps. However, these units also bypass the spirit of the mandates, which was intended to better protect our environment by moving the air conditioning industry to a more environmentally friendly refrigerant.

the Niagara Region homeowners should know that these Dry Charged Units are approved in the U.S. and Canada. Because of some key ambiguities in the written policies, the entire outdoor unit is technically deemed a replacement “part”. Today, condensers or heat pumps intended for use in a replacement R-22 system are now referred to as “Dry Charge” or “Nitrogen Charged” systems. Below are some Frequently Asked Questions about this recent A/C Dry Charge trend.

Does it make sense to buy a Dry Charge Air Conditioning Unit?

The answer to this question hinges on a number of things. The best thing to do is understand what types of HVAC equipment the heating and air conditioning industry has to offer and seek solutions that speaks to your personal comfort, efficiency and lifestyle needs. Take time to understand the benefits and difference between a dry charge unit and new air conditioning products with R-410A refrigerant.

Reasons to buy an R-410A refrigerant system

Current R-410A systems provide benefits to the Niagara Region homeowners that Dry Charge units do not. A sample of the benefits include:

  • Increased energy efficiency for affordable in-home comfort
  • Modern technology to lower humidity
  • Current production refrigerant solutions guaranteeing longer life and extended availability of refrigerant
  • Longer warranty periods for even greater peace of mind
  • Quieter operation for a more peaceful indoor environment
  • Ozone friendly refrigerant for lower impact on the environment
  • Matched coil solutions for increased reliability and guaranteed cooling and heating performance

Are Dry Change Air Conditioning Unit legal to install?

Yes. There are no Federal laws or legal restriction on the installation of R-22 or Dry Charge Equipment, however, it can only be used as a repair to an existing system.

What about the warranty?

The majority of manufacturers honor a standard 5-year parts warranty on dry charge units. While this offers industry standard protection on the components it does not provide protection against R-22 refrigerant prices, which are expected to increase significantly.

Is R-22 refrigerant going to get really expensive?

It is likely that as a result of supply and demand, the refrigerant will probably go up in price. As the phase out process of R22 continues, new R-22 refrigerant production will progressively be reduced, with full elimination of its production in 2020. Until then, indications are that there will likely be sufficient supply to meet the current demand.
