What's an Air Conditioning Dry Charge?

April 01, 2015

Over the past decade, both the U.S. and Canadian governments have instructed that all manufacturers of air conditioning equipment halt production of the refrigerant R-22 (Freon) or Hydrochlorofluorocarbons (HCFCs). These refrigerants have been standardly used in air conditioners and heat pumps for many decades. These mandates are expected to have the HVAC industry move 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 producers began manufacturing Air Conditioning and Heat Pump units, without adding refrigerant at the factory. These units are more commonly called “dry charged units”. The units can legally be sold and installed then your local HVAC contractor (such as Jack Nelson Service Experts Heating & Air Conditioning) can charge the unit with R22. R22 is still legal for AC repair or service a while longer. The purpose of these Dry Charged Units is to offer the greater Tulsa 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.

Tulsa homeowners should be aware 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”. These days, condensers or heat pumps intended for use in a replacement R-22 system are now 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?

It depends on a number of things. The number one 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 offer benefits to Tulsa homeowners that Dry Charge units do not. Some of the benefits include:

  • Greater energy efficiency for affordable in-home comfort
  • State-of-the-art technology to lower humidity
  • Current production refrigerant solutions guaranteeing longer life and extended availability of refrigerant
  • Expanded warranty periods for even greater peace of mind
  • Quieter operation for a more peaceful indoor environment
  • Ozone friendly refrigerant for lower impact on the environment
  • Matched coil solutions for increased reliability and guaranteed cooling and heating performance

Are Dry Charge units legal?

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?

Most 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 substantially.

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 slowly be reduced, with full elimination of its production in 2020. Until that date, indications are that there will likely be sufficient supply to meet the current demand.
