Over the past several years, both the U.S. and Canadian governments have mandated that all producers of air conditioning equipment stop 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. These mandates are suppose to have the HVAC industry turn to a more earth friendly refrigerant with a technical label R410A. R410A has been verified 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 systems are more commonly called “dry charged units”. The units can legally be sold and installed which permits your Cleveland area HVAC contractor to charge the unit on-site with R22. R22 is still legal for AC repair or service for a few more years. The purpose of these Dry Charged Units is to provide the greater Cleveland area a more simple and affordable replacement option for central air conditioners and heat pumps. However, these units also bypass the spirit of the mandates, which was to wean the industry off less eco-friendly refrigerants.
Cleveland homeowners should be aware that these Dry Charged Units are permitted 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 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?
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.
Reasons to buy an R-410A refrigerant system
Current R-410A systems offer benefits to Cleveland homeowners that Dry Charge units do not. A sample of the benefits include:
- Increased energy efficiency for reduced cost of comfort
- State-of-the-art technology to lessen 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 that protects the environment
- Matched coil solutions for enhanced reliability and guaranteed cooling and heating performance
Are Dry Charge units legal?
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.
Is there a warranty that comes with it?
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 substantially.
How expensive will R-22 get in the next few years?
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 that time however, indications are that there will likely be sufficient supply to meet the current demand.
