Over the past several years, both the U.S. and Canadian governments have mandated that all producers of air conditioning equipment halt production of the refrigerant R-22 (Freon) or Hydrochlorofluorocarbons (HCFCs). These refrigerants have been standardly used in air conditioners and heat pumps for many decades. The recommended phase-out mandates are suppose to have the HVAC industry shift to a more earth friendly refrigerant with a technical label R410A. R410A has been verified to be safer for the environment.
In late 2010 the majority of air conditioning manufacturers began manufacturing Air Conditioning and Heat Pump units, without adding refrigerant at the factory. These systems are more commonly called “dry charged units”. These A/C units can legally be sold and installed which permits your Buffalo area HVAC contractor to charge the unit on-site with R22. R22 is still legal for AC repair or service for a few more years. The purpose of these Dry Charged Units is to offer the greater Buffalo area a more simple and cost effective replacement option for central air conditioners and heat pumps. However, these units also dodge the spirit of the mandates, which was to wean the industry off less eco-friendly refrigerants.
Buffalo homeowners should know 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 looked upon as a replacement “part”. Today, 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?
Well, it really depends on a number of things. The most important thing to do is determine what types of HVAC equipment the heating and air conditioning industry can offer 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 have many benefits to Buffalo homeowners that Dry Charge units do not. Some of the benefits include:
- Increased energy efficiency for comfort at a cost savings
- State-of-the-art technology to lower humidity
- Current production refrigerant solutions ensuring longer life and extended availability of refrigerant
- Expanded 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 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.
What about the warranty?
Major manufacturers honor 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.
How expensive will R-22 get in the next few years?
It is likely that as a result of supply and demand, the answer to this question is “yes – we do anticipate R-22 refrigerant to get pricey”. 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 time however, indications are that there will likely be sufficient supply to meet the current demand.
