What's an Air Conditioning Dry Charge?

April 01, 2015

Over the past decade, both the U.S. and Canadian governments have directed that all producers of air conditioning equipment stop production of the refrigerant R-22 (Freon) or Hydrochlorofluorocarbons (HCFCs). These refrigerants have been commonly used in air conditioners and heat pumps for the last several decades. The R-22 and HCFC mandates are intended to have the HVAC industry shift to a more earth friendly refrigerant with a technical code R410A. R410A has been verified to be safer for the environment.

In late 2010 the majority of air conditioning firms began manufacturing Air Conditioning and Heat Pump units, without adding refrigerant at the factory. These systems are more commonly called “dry charged units”. The units can legally be sold and installed which permits your Melbourne area HVAC contractor to charge the unit on-site with R22. R22 is still legal for AC repair or service a while longer. The reason for these Dry Charged Units is to offer the greater Melbourne area a more simple and affordable replacement option for central air conditioners and heat pumps. However, these units also dodge the spirit of the mandates, which was to wean the industry off less eco-friendly refrigerants.

Melbourne homeowners should be aware that these Dry Charged Units are allowed in the U.S. and Canada. Because of the lack of clarity regarding the definition of an outdoor unit in the rules, the entire outdoor unit is technically considered a replacement “part”. These days, condensers or heat pumps intended for use in a replacement R-22 system are often referred to as “Dry Charge” or “Nitrogen Charged” systems. The following 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?

Well, it really depends on a number of things. The best thing to do is understand what types of HVAC equipment the heating and air conditioning industry offers and seek solutions to address 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.

Top reasons for buying an R-410A system

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

  • Increased energy efficiency for comfort at a cost savings
  • State-of-the-art technology to lessen humidity
  • Current production refrigerant solutions guaranteeing longer life and extended availability of refrigerant
  • Expanded warranty periods for more peace of mind
  • Quieter operation for a more peaceful indoor environment
  • Ozone friendly refrigerant that reduces the carbon imprint that negatively impacts our environment
  • Matched coil solutions for improved reliability and guaranteed cooling and heating performance

Are Dry Charge units legal?

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.

Is there a warranty that comes with it?

Most manufacturers have established a standard 5-year parts warranty on dry charge units. While this provides industry standard protection on the components it does not provide protection against R-22 refrigerant prices, which are expected to increase significantly.

How expensive will R-22 get in the next few years?

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 gradually 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.
