What’s an Air Conditioning Dry Charge?

Over the past decade, both the U.S. and Canadian governments have directed that all manufacturers of air conditioning equipment halt production of the refrigerant R-22 (Freon) or Hydrochlorofluorocarbons (HCFCs). These refrigerants have been typically used in air conditioners and heat pumps for the last several decades. These mandates are suppose to have the HVAC industry turn to a more environmentally friendly refrigerant with a technical designation R410A. R410A has been shown 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. Such systems are more commonly called “dry charged units”. The units 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 Wheeling area a more simple and relatively inexpensive replacement option for central air conditioners and heat pumps. However, these units also circumvent the spirit of the mandates, which was to wean the industry off less eco-friendly refrigerants. 

Wheeling homeowners should understand that these Dry Charged Units are approved 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 deemed a replacement “part”. Today, 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 number one 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. 

Why would I buy a R-410A refrigerant system? 

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

  • Increased energy efficiency for reduced cost of comfort 
  • Modern technology to lower humidity 
  • Current production refrigerant solutions guaranteeing longer life and extended availability of refrigerant 
  • Extended warranty periods for significant peace of mind 
  • Quieter operation for a more peaceful indoor environment 
  • Ozone friendly refrigerant for lower impact on the environment 
  • Matched coil solutions for improved reliability and guaranteed cooling and heating performance 

Is it legal to install Dry Charge units? 

Definitely. 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? 

The majority of manufacturers honor 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 dramatically. 

Will the R-22 refrigerant be expensive to buy? 

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 gradually 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.
