Over the past several years, 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. The recommended phase-out mandates are intended to have the HVAC industry move to a more environmentally friendly refrigerant with a technical code R410A. R410A has been proven to be safer for the environment.
In late 2010 the majority of air conditioning companies began manufacturing Air Conditioning and Heat Pump units, without adding refrigerant at the factory. Such systems are more commonly called “dry charged units”. They can legally be sold and installed which permits your Dayton 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 intent for these Dry Charged Units is to provide the greater Dayton 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 intended to better protect our environment by moving the air conditioning industry to a more environmentally friendly refrigerant.
Dayton 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 deemed 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?
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 has to offer 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.
Why would I buy a R-410A refrigerant system?
Current R-410A systems offer benefits to Dayton homeowners that Dry Charge units do not. A few of the benefits include:
- Improved energy efficiency for comfort at a cost savings
- State-of-the-art technology to lower humidity
- Current production refrigerant solutions guaranteeing longer life and extended availability of refrigerant
- Extended 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 improved reliability and guaranteed cooling and heating performance
Is it legal to install Dry Charge units?
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.
What about the warranty?
The majority of 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 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 that time however, indications are that there will likely be sufficient supply to meet the current demand.
