Over the past several years, both the U.S. and Canadian governments have directed that all producers 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 the last several decades. These mandates are anticipated to have the HVAC industry turn to a more green 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 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 Westminster area a more simple and affordable replacement option for central air conditioners and heat pumps. However, these units also bypass 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.
Westminster 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 looked upon as 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.
Should I buy a “Dry Charge” A/C system?
Well, it really 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 offers 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.
Reasons to buy an R-410A refrigerant system
Current R-410A systems offer benefits to Westminster 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
- Longer warranty periods for significant peace of mind
- Quieter operation for a more peaceful indoor environment
- Earth 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?
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 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 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.
