Over the past several years, both the U.S. and Canadian governments have instructed that all makers 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 a long time. These mandates are suppose to have the HVAC industry turn to a more green friendly refrigerant with a technical label R410A. R410A has been proven to be safer for the environment.
In late 2010 reputable 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”. The units can legally be sold and installed which permits your Shreveport area HVAC contractor to charge the unit on-site 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 provide the greater Shreveport area a more simple and cost effective replacement option for central air conditioners and heat pumps. However, these units also circumvent the spirit of the mandates, which was intended to better protect our environment by moving the air conditioning industry to a more environmentally friendly refrigerant.
Shreveport homeowners should know 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 looked upon as a replacement “part”. These days, condensers or heat pumps intended for use in a replacement R-22 system are usually 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 most important thing to do is learn what types of HVAC equipment the heating and air conditioning industry can 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.
Top reasons for buying an R-410A system
Current R-410A systems have many benefits to Shreveport homeowners that Dry Charge units do not. Some of the benefits include:
- Greater energy efficiency for comfort at a cost savings
- 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
- Earth friendly refrigerant for lower impact on the environment
- Matched coil solutions for improved reliability and guaranteed cooling and heating performance
Is it legal to install Dry Charge units?
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 dramatically.
Will the R-22 refrigerant be expensive to buy?
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 progressively 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.
