What's an Air Conditioning Dry Charge?

April 01, 2015

Over the past several years, both the U.S. and Canadian governments have mandated that all makers of air conditioning equipment phase out 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 recommended phase-out mandates are expected to have the HVAC industry shift to a more environmentally friendly refrigerant with a technical label R410A. R410A has been verified to be safer for the environment.

In late 2010 most 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”. These A/C 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 few more years. The reason for these Dry Charged Units is to provide the greater Ravenna 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 help the environment by introducing more environment friendly solutions.

Ravenna homeowners should understand that these Dry Charged Units are allowed 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 considered a replacement “part”. Today, condensers or heat pumps intended for use in a replacement R-22 system are now referred to as “Dry Charge” or “Nitrogen Charged” systems. The following are some Frequently Asked Questions about this recent A/C Dry Charge trend.

Do you recommend purchasing a Dry Charge Air Conditioning System?

The answer to this question hinges on a number of things. The best thing to do is learn what types of HVAC equipment the heating and air conditioning industry can offer 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.

Top reasons for buying an R-410A system

Current R-410A systems provide benefits to Ravenna homeowners that Dry Charge units do not. Some of the benefits include:

  • Improved energy efficiency for reduced cost of comfort
  • Modern technology to lessen humidity
  • Current production refrigerant solutions guaranteeing longer life and extended availability of refrigerant
  • Longer warranty periods for even greater peace of mind
  • Quieter operation for a more peaceful indoor environment
  • Earth friendly refrigerant that protects the environment
  • Matched coil solutions for increased reliability and guaranteed cooling and heating performance

Are Dry Charge units legal?

Absolutely. 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 have established 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 answer to this question is “yes – we do anticipate R-22 refrigerant to get pricey”. 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.
