Over the past 10 years, both the U.S. and Canadian governments have mandated that all manufacturers of air conditioning equipment stop production of the refrigerant R-22 (Freon) or Hydrochlorofluorocarbons (HCFCs). These refrigerants have been typically used in air conditioners and heat pumps for a long time. The recommended phase-out mandates are anticipated to have the HVAC industry turn to a more environmentally friendly refrigerant with a technical designation R410A. R410A has been shown to be safer for the environment.
In late 2010 reputable air conditioning producers began manufacturing Air Conditioning and Heat Pump units, without adding refrigerant at the factory. These units are more commonly called “dry charged units”. These A/C units can legally be sold and installed which permits your Kingston area HVAC contractor to charge the unit on-site with R22. R22 is still legal for AC repair or service a while longer. The purpose of these Dry Charged Units is to provide the greater Kingston area a more simple and relatively inexpensive replacement option for central air conditioners and heat pumps. However, these units also bypass the spirit of the mandates, which was to help the environment by introducing more environment friendly solutions.
Kingston homeowners should be aware 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 now referred to as “Dry Charge” or “Nitrogen Charged” systems. Here 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 learn what types of HVAC equipment the heating and air conditioning industry offers 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.
Why would I buy a R-410A refrigerant system?
Current R-410A systems offer benefits to Kingston homeowners that Dry Charge units do not. Some of the benefits include:
- Increased energy efficiency for reduced cost of comfort
- Modern technology to lessen humidity
- Current production refrigerant solutions ensuring longer life and extended availability of refrigerant
- Expanded warranty periods for more 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 increased 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, with the stipulation that it is repairing an existing air conditioning system.
Does a warranty come with a Dry Charge Unit?
Most manufacturers have 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 significantly.
Is R-22 refrigerant going to get really expensive?
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 then, indications are that there will likely be sufficient supply to meet the current demand.
