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 typically used in air conditioners and heat pumps for a long time. These mandates are suppose 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 most air conditioning firms began manufacturing Air Conditioning and Heat Pump units, without adding refrigerant at the factory. These units are more commonly called “dry charged units”. They 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 short time longer. The intent for these Dry Charged Units is to provide the greater Kitchener area a more simple and cost effective replacement option for central air conditioners and heat pumps. However, these units also bypass the spirit of the mandates, which was to wean the industry off less eco-friendly refrigerants.
Kitchener homeowners should understand that these Dry Charged Units are approved in the U.S. and Canada. Taking advantage of an unclear definition of the outdoor unit in these policies, the entire outdoor unit is technically looked upon as a replacement “part”. Today, condensers or heat pumps intended for use in a replacement R-22 system are usually 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?
It depends on a number of things. The best thing to do is determine 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.
Why would I buy a R-410A refrigerant system?
Current R-410A systems offer benefits to Kitchener homeowners that Dry Charge units do not. Some of the benefits include:
- Increased energy efficiency for reduced cost of comfort
- State-of-the-art technology to lessen humidity
- Current production refrigerant solutions ensuring 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?
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.
Is there a warranty that comes with it?
The majority of manufacturers have 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 substantially.
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 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.
