What’s an Air Conditioning Dry Charge?

Over the past decade, both the U.S. and Canadian governments have directed that all makers 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 reputable 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 Saint Charles area HVAC contractor to charge the unit on-site with R22. R22 is still legal for AC repair or service for a short time longer. The purpose of these Dry Charged Units is to provide the greater Saint Charles area a more simple and affordable replacement option for central air conditioners and heat pumps. However, these units also circumvent the spirit of the mandates, which was to help the environment by introducing more environment friendly solutions. 

Saint Charles homeowners should understand that these Dry Charged Units are approved in the U.S. and Canada. Taking advantage of an unclear definition of the outdoor unit in these policies, the entire outdoor unit is technically looked upon as 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. Below are some Frequently Asked Questions about this recent A/C Dry Charge trend. 

Do you recommend purchasing a Dry Charge Air Conditioning System? 

Well, it really depends on a number of things. The best thing to do is determine what types of HVAC equipment the heating and air conditioning industry has to offer and seek solutions to meet 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 provide benefits to Saint Charles homeowners that Dry Charge units do not. A sample of the benefits include: 

• Improved energy efficiency for comfort at a cost savings 
• State-of-the-art technology to reduce 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 
• Eco 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? 

Definitely. 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, 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.
