Most of the newer hybrids have changed to an inverter compressor, which is a high-voltage electrical motor.
Bosch Broadens Fast-Growing Cabin Air Filter Coverage With Additional Part Numbers
With more and more OEMs offering cabin air filters in their vehicles, Bosch says it is expanding in this fast-growing product segment with new part numbers. The Bosch Workshop Cabin Air Filter line has expanded to include 23 new part numbers that cover 17.6 million additional vehicles in North America – domestic, European and Asian – with the same fit and function as OE cabin air filters, according to the company.
Is A New Refrigerant Going To Replace R-134a?
Yes, but the question is when? The new refrigerant is HFO-1234yf. Its cooling performance is very close to R-134a (the refrigerant that is currently used in all new cars and trucks), but it has a much lower Global Warming Potential Rating (only 4 versus 1430 for R-134a), making HFO-1234yf a much better refrigerant in terms of its potential impact on climate change.
Directions: SAE Clears The Air On HFO-1234yf A/C Refrigerant
Honeywell has reported that SAE International has deemed its new low-global-warming-potential mobile air conditioning refrigerant – HFO-1234yf – safe for use in motor vehicles. SAE made the recommendation following an expanded and extensive evaluation.
SAE International, Consortium Of 11 Global Automakers Conclude Honeywell’s Low-Global-Warming Refrigerant Safe For Use In Cars
Honeywell has announced that SAE International has concluded that Honeywell’s new low-global-warming-potential mobile air conditioning refrigerant, HFO-1234yf, is safe for use in automobiles after completing an expanded and extensive evaluation.
Selling More AC Work
Here’s a tip that’s particularly effective during the hot summer months! Tell your techs that when they go for a test drive, they should stick a thermometer in the AC outlet. If it’s not as cool as it should be, all that they need to do is write the recorded temperature down on the repair order.

When a customer comes in complaining that their vehicle’s A/C system is working improperly, the problem can stem from a number of things. And the best way to begin any A/C repair is with a thorough inspection of the components. After checking components like the belts, the hoses and the related connections, the next step is a visual inspection of the A/C compressor.
