What Is An Air Conditioning Dry Charge?

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

In late 2010 the majority of air conditioning manufacturers 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 which permits your Edmonton 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 provide the greater Edmonton 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 help the environment by introducing more environment friendly solutions.

Edmonton homeowners should be aware 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 considered a replacement “part”. As a result, condensers or heat pumps intended for use in a replacement R-22 system are often referred to as “Dry Charge” or “Nitrogen Charged” systems. Here are some Frequently Asked Questions about this recent A/C Dry Charge trend.

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

The answer to this question hinges on a number of things. The number one thing to do is determine what types of HVAC equipment the heating and air conditioning industry can 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 offer benefits to Edmonton homeowners that Dry Charge units do not. A few of the benefits include:

• Increased energy efficiency for affordable in-home comfort
• Modern 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 protects the environment
• Matched coil solutions for increased reliability and guaranteed cooling and heating performance

Are Dry Change Air Conditioning Unit legal to install?

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.

What about the warranty?

The majority of manufacturers have 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, 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.
