What's an Air Conditioning Dry Charge?

April 01, 2015

Over the past 10 years, both the U.S. and Canadian governments have directed that all makers 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. These mandates are intended 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 producers began manufacturing Air Conditioning and Heat Pump units, without adding refrigerant at the factory. Such systems are more commonly called “dry charged units”. These A/C units can legally be sold and installed then your local HVAC contractor (such as Rolf Griffin Service Experts Heating & Air Conditioning) can charge the unit with R22. R22 is still legal for AC repair or service a while longer. The reason for these Dry Charged Units is to provide the greater Fort Wayne area a more simple and relatively inexpensive 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.

Fort Wayne homeowners should be aware that these Dry Charged Units are permitted 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”. As a result, condensers or heat pumps intended for use in a replacement R-22 system are usually referred to as “Dry Charge” or “Nitrogen Charged” systems. The following are some Frequently Asked Questions about this recent A/C Dry Charge trend.

Should I buy a “Dry Charge” A/C system?

It depends on a number of things. The best thing to do is learn 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.

Reasons to buy an R-410A refrigerant system

Current R-410A systems have many benefits to Fort Wayne homeowners that Dry Charge units do not. Some of the benefits include:

  • Increased energy efficiency for reduced cost of comfort
  • State-of-the-art technology to lower humidity
  • Current production refrigerant solutions allowing longer life and extended availability of refrigerant
  • Extended warranty periods for even greater 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

Is it legal to install Dry Charge units?

Yes. There are no Federal laws or legal restriction on the installation of R-22 or Dry Charge Equipment, as long as it is as a repair for an existing system.

Does a warranty come with a Dry Charge Unit?

Most manufacturers have 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 dramatically.

Is R-22 refrigerant going to get really expensive?

It is likely that as a result of supply and demand, R-22 refrigerant will become more expensive. As the phase out process of R22 continues, new R-22 refrigerant production will slowly be reduced, with full elimination of its production in 2020. Until that time however, indications are that there will likely be sufficient supply to meet the current demand.
