R22 Refigerant Phase Out – Environmental Impact

What does the R-22 Refrigerant Phase out mean for your Hvac system?

The current phase of of R-22 Refrigerant in residential and commercial properties leaves home and business owners with unanswered questions. As R-22 (Freon) is gradually phased out, alternative refrigerants are being introduced. One of these substitutes is R-410A, also known as Puron, a blend of hydro-fluorocarbons (HFCs) that does not contribute to depletion of the ozone layer.

HCFC Phase out

Service to current HVAC systems

Production of new air conditioning units charged with R-22 ended in 2010, and by 2020, the servicing of R-22 based systems will rely solely on recycled or reclaimed refrigerants.

If your air conditioner was manufactured before 2010, it probably utilizes R-22. The good news is existing units using R-22 can continue to be serviced with R-22 as there is no EPA requirement for change or conversion of these units.

More than likely, your heating and cooling units will have sufficient R-22, unless a leak occurs. Since production is limited, costs to charge existing units leaking R-22 refrigerant have gone up and are expected to rise. We urge our customers to take the necessary steps to protect yourself from the rising cost of refrigerant. The best thing you can do properly maintain your unit to prevent leaks. You can do so by participating in routine tune-ups in the spring and fall. Remember, routine maintenance is far less expensive than emergency repairs.

Retrofits and Converting units

Retrofit units, converted R-22 units utilize a substitute refrigerant, are allowed if the alternative has been found acceptable for that type of use. Substitute refrigerant can work well in R-22 units with a few changes to system components. For example, simply replacing R-22 refrigerant with R-410A in a preexisting R-22 unit is not recommended due to its higher worker pressure. However, a certified professional can replace R-22 condensers with R-410A condensers, as long as the system coil is also updated. This provides consistency in the refrigerant  cycle, as one coil cannot be replaced without the other, and allows the retrofit to get you by for several more years.

The EPA warns of potential safety hazards related to the use of unapproved refrigerants in home air conditioning systems as they are not designed to handle flammable refrigerants.

Impact on the environment

Properly installed home comfort systems rarely develop major refrigerant leaks, and with proper servicing, a system using R-22, R-410A, or another refrigerant will reduce its impact on the environment. Remember to always select a reputable dealer to handle refrigerants.

Refrigerant R-22 is used in a number of refrigeration and air conditioning systems. R-22 is the halocarbon compound named monochlorodifluoromethane with chemical formula CHCIF2 and it is the hydrochlorofluorocarbon (HCFC). R-22 is one of the most popular refrigerant used in cooling system, but unfortunately, the halocarbons (chlorine and fluorine) present in these compounds have the potential to cause depletion of the ozone layer in the atmosphere leading to greenhouse effect. The ozone layer destroying potential of R-22, which is HCFC is much lesser than the other chlorofluorocarbons (CFCs), still in the long-term they do have detrimental effects on the atmosphere.

The depletion of ozone layer from the upper layers of atmosphere results in ultraviolet rays of the sun to reach the surface of the earth. This leads to high temperature on the earth and the ultraviolet ray themselves are very harmful to the skin of humans. To avoid the long-term dangers of the R-22 and other CFCs, it has been decided to phase out the use and production of R-22 completely along with other CFC refrigerants.

New units

A important thing a homeowner can do for the environment is to purchase a highly energy efficient system. Today’s air conditioners use much less energy, provide cost savings in maintenance an electric costs, and offer a green alternative to R-22 units. Rebates and tax credits also help to offset the cost of new systems.

The best time to switch is before your hit by the high costs of repairing a refrigerant system. Take into account the age of your current unit (as a general rule, systems should be older than 10 years) look for the energy star label to save up to 40 percent on utility bills and consider the minimum seasonal energy efficiency ratio (SEER) specification.

Frost Free Faucets – Woodford model 19

How A Standard Frost-Proof Faucet Works

The product is designed to be frost-proof when installed properly (with a slight downward pitch) and there is no restriction on the hose nozzle to prevent the faucet from draining. If a hose is attached during freezing weather, water is trapped inside the faucet which may cause the faucet to freeze and burst.

pitch-correctandincorrect

When the faucet’s valve in the closed position, the water is shut off several inches into the home. The water line does not freeze because of the heat in the home. The product cannot freeze because there is no water in the faucet. When the valve is turned off, all of the water in front of the valve drains from the faucet leaving the tube empty. Also shown is correct and incorrect installation and a frozen split tube condition when hose is left on during freezing weather.

When a hose or other restriction is left attached, the water cannot drain from the faucet properly. As the temperature drops below freezing, the water in the faucet begins to freeze. The freezing conditions are applied from the outside of the house back toward the interior as the water continues to freeze. Once the water has frozen into the faucet itself, if the faucet has been shut off, there is no relief from this expanding pressure. Eventually the copper tubing will burst to relieve the pressure. No noticeable damage is visible in the home at this time. Only a few drops of water will leak through this bulge at the time of the bursting. Once the weather warms, the ice in the faucet will melt. Since the burst in the tubing is after the shut off valve, water will not leak out of the burst tubing until the water is turned on. Thus, there can be a considerable amount of time between the actual rupture of the tubing and the discovery of the problem.

Woodford Wall Faucets

Woodford manufacturers the best outdoor sill faucets and hydrants. Available with vacuum breaker and burst protection, Woodford has the best commercial and residential wall hydrants for all types of use.

Woodford Freezeless Wall Faucet Model 17

The Woodford 17CP-8-MH is a Model 17 Series freezeless wall faucet will not rupture when hose is removed and valve is shut off and features an anti-siphon for backflow prevention with a 1/2″ male thread or 1/2″ female copper inlet and has a powder coated cast aluminum handle and includes an integral backflow prevention device and uses an atmospheric vent and patented check to provide anti-siphon protection.

Warranty

All Model 19 Wall Faucets are sold with a limited warranty for five years against defects in material and workmanship. We will replace for inspection and found to be defective within 5 years of purchase from Woodford. In addition, Woodford will pay up to $5,000 toward the cost to repair damages incurred as a result of a defective Model 19 Wall Faucet that was properly installed.

This limited warranty does not cover defects caused by:

  • modifications,
  • alterations or repair of the product by anyone other than Woodford;
  • physical abuse to, or misuse of, the product or operation thereof in a manner contrary to the accompanying instructions.

BURIED HYDRANTS

Welcome spring weather! With the warmer weather comes yard work and outdoor maintenance. When your hydrants drips or the handle seizes, most hydrants are not repairable. They would have to be dug up and replaced. They are usually 4 feet deep or more.  Remember in the fall to unhook your hose and cover the faucet with a trash bag and wire wrap to prevent it from damage from the freezing weather.
