AIR CONDITIONING FREON UPDATE

 

Gene-Car-Talk

In an effort to slow down the human factor in global warming, car manufacturers in the USA will now receive substantial CO2 credits which means more miles to the gallon if they comply with the plan to phase out R-134a refrigerant. Europe has already ramped up in this area.

The new EPA regulation states that R-134a cannot be installed in new cars and light trucks built for domestic sale after 2021. Similar regulations for medium and heavy-duty trucks are coming this year, so the 2021 deadline may affect all domestic vehicles by that time. Vehicles for export will still be able to use R-134a systems until 2025.

In the meantime, Daimler, which had charged that the alternative refrigerant R-1234yf posed potential fire safety dangers, has finally agreed to use R-1234yf systems in its Mercedes vehicles for markets where the refrigerant either is mandated or is effectively pressed for by regulatory bodies (as in the U.S.). There has not been a set rollout schedule, however. Daimler stated that it will add an under the hood argon gas canister with spray lines directed at all parts that its engineers say might become hot enough for a leaking refrigerant to ignite. It will be a fire-extinguisher of sorts.

R-1234yf cannot be retrofitted to R-134a systems so production of R-134a will continue indefinitely for service. The R-1234yf CAFE credits are 13.8 g/mi for cars, 17.2 g/mi for trucks. (GWP, a metric used by environmental regulatory agencies worldwide, is a measure of how much a given mass of a gas contributes to global warming. It is a relative scale which compares the amount of heat trapped by greenhouse gas to the amount of heat trapped in an equal mass of CO2.

Fiat Chrysler Automobiles began transitioning its changeover in 2014MY. General Motors has had just one entry in that period, the Cadillac XTS, but GM will be virtually across the board by the end of this year. Ford says it will begin its changeover in April with the Escape, but no details of its rollout are available. Sending vehicles with either refrigerant down the same assembly line is not a difficult process.

The price of R-1234yf is reported to me much higher that R-134a.  We at Certified Automotive Specialists wanted Glendora drivers to know what is coming!  To find out more about air conditioning and Freon (refrigerant) visit our website.

IS YOUR AIR CONDITIONER READY FOR WARMER DAYS?

Spring is in the air and many of our customers’ thoughts turn to…air conditioning.  We get countless calls asking us how much it costs to fix.  There is no one simple answer to this question but I’ll give you some industry-wide estimates so you have something to go on. Generally, if you drive an older vehicle it will cost more to fix because the parts will be harder to find.

 

Testing the A/C System: A technician must test the system to determine what is wrong with it.  This requires a test for leaks and an inspection of the parts such as the compressor, condenser, hoses, and valves. This usually costs somewhere between $175 and $700.

 

Recharging the A/C System: This is the most common fix of the A/C system.  It needs refrigerant added and it needs to be able to flow through the system properly.  This cost is generally $80 to $275.

 

Leaking Hose:  Finding and fixing a leak in the A/C system can take time and isn’t as easy as it sounds. This costs between $400 and $1,100.

 

Broken Compressor:  This is the most complex of all to fix and costs from $275 to $500.

 

Replacing the Unit:  The cost of this is determined by the make and model you drive.  The cost to repair starts at $1,800 and can go as high as $2,900.

 

Working on air conditioning systems is not easy.  The system itself is built in and around your car’s engine making it difficult.  Specialized equipment is required and a technician that is certified in this area is a must.  In some countries it is illegal for a non-authorized technician to work on A/C systems. A non-experienced technician can inadvertently cause problems and contaminate the environment.

 

These prices are not set in stone but an industry-wide average.  Have a certified technician give you an estimate after they have diagnosed your vehicle.
