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 manufacturers of air conditioning equipment stop 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. The R-22 and HCFC mandates are anticipated to have the HVAC industry turn to a more earth friendly refrigerant with a technical code R410A. R410A has been proven 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”. The units can legally be sold and installed then your local HVAC contractor (such as Service Experts Heating & Air Conditioning) can charge the unit 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 give the greater Canada area a more simple and relatively inexpensive replacement option for central air conditioners and heat pumps. However, these units also bypass the spirit of the mandates, which was to help the environment by introducing more environment friendly solutions.

Canada homeowners should know that these Dry Charged Units are allowed in the U.S. and Canada. Because of some key ambiguities in the written policies, the entire outdoor unit is technically deemed 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. Here are some Frequently Asked Questions about this recent A/C Dry Charge trend.

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

Well, it really depends on a number of things. The number one thing to do is determine what types of HVAC equipment the heating and air conditioning industry offers 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 have many benefits to Canada homeowners that Dry Charge units do not. Some of the benefits include:

  • Improved energy efficiency for reduced cost of comfort
  • Modern technology to lower humidity
  • Current production refrigerant solutions ensuring longer life and extended availability of refrigerant
  • Expanded 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 improved reliability and guaranteed cooling and heating performance

Are Dry Change Air Conditioning Unit legal to install?

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?

Major manufacturers have established a standard 5-year parts warranty on dry charge units. While this affords 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 then, indications are that there will likely be sufficient supply to meet the current demand.
