Over the past decade, both the U.S. and Canadian governments have instructed that all manufacturers of air conditioning equipment stop 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. The recommended phase-out mandates are anticipated to have the HVAC industry move to a more earth friendly refrigerant with a technical code R410A. R410A has been proven to be safer for the environment.
In late 2010 most 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”. These A/C units can legally be sold and installed which permits your Edmonton 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 give the greater Edmonton 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 wean the industry off less eco-friendly refrigerants.
Edmonton homeowners should be aware that these Dry Charged Units are allowed in the U.S. and Canada. Because of some key ambiguities in the written policies, the entire outdoor unit is technically deemed a replacement “part”. As a result, condensers or heat pumps intended for use in a replacement R-22 system are often referred to as “Dry Charge” or “Nitrogen Charged” systems. Here are some Frequently Asked Questions about this recent A/C Dry Charge trend.
Does it make sense to buy a Dry Charge Air Conditioning Unit?
Well, it really depends 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.
Reasons to buy an R-410A refrigerant system
Current R-410A systems have many benefits to Edmonton homeowners that Dry Charge units do not. Some 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
- Expanded warranty periods for even greater peace of mind
- Quieter operation for a more peaceful indoor environment
- Eco friendly refrigerant that reduces the carbon imprint that negatively impacts our environment
- Matched coil solutions for improved 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.
What about the warranty?
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.
How expensive will R-22 get in the next few years?
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 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.
