Benefits of Our New R1234yf Air Conditioning Machine

r1234yf Air Conditioning Machine Watsonville

Our shop is committed to helping customers get the latest solutions while doing our part to help the environment. As a result, we have started to offer air conditioning solutions that rely on new R1234yf refrigerants that have less potential to harm the environment than conventional refrigerants. Although there are few vehicles that continue to use Freon, a refrigerant that has been proven to damage the ozone layer, the standard R134a refrigerants that have replaced Freon have also been shown to have the potential to harm the environment.

Studies have shown that R134a has a high global warming potential, and it can contribute directly to the emission of greenhouse gasses. Consequently, vehicles that rely on R124a will fail to meet the European Union's directives on greenhouse gasses that went into effect in 2017, and they will increasingly be banned from other countries as time goes on.

About Us The Kadotani mission statement.

Kadotani Auto Repair has been in business for over 38 years! David and Jeanni Kadotani have built a great reputation for caring greatly about their customers and the vehicles they drive. After all those years, David and Jeanni have finally decided to retire and enjoy some much needed family time and tandem bike rides. David and Jeanni wanted to be sure that the customers they have built a long term relationship with were in good hands when they retired, so who better to take care of them than someone who has actually been working on their cars out in the shop? That’s where the new owner Kellen comes in.

I know our customers will be in great hands with Kellen running the business. He knows what he is doing, is young and very up to date with late model vehicles and the heavily computer based knowledge needed to diagnose many of today’s intricate systems. Jeanni and I want to thank everyone for the decades of support and we will still be around so you might find us on the bicycle! - David Kadotani
