Over the past 10 years, both the U.S. and Canadian governments have instructed that all makers of air conditioning equipment phase out 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. The recommended phase-out mandates are anticipated to have the HVAC industry shift to a more earth friendly refrigerant with a technical code R410A. R410A has been verified to be safer for the environment.
In late 2010 reputable 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 allowing the HVAC contractor to charge the unit in the field 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 offer the greater Oakville area a more simple and affordable 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.
Oakville homeowners should know that these Dry Charged Units are approved 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. 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?
It depends on a number of things. The number one thing to do is determine what types of HVAC equipment the heating and air conditioning industry can 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 provide benefits to Oakville homeowners that Dry Charge units do not. Some of the benefits include:
- Increased energy efficiency for affordable in-home comfort
- Leading technology to lower humidity
- Current production refrigerant solutions allowing 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 reduces the carbon imprint that negatively impacts our environment
- Matched coil solutions for improved reliability and guaranteed cooling and heating performance
Are Dry Change Air Conditioning Unit legal to install?
Yes. 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?
Most manufacturers have established a standard 5-year parts warranty on dry charge units. While this affords 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 gradually 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.
