I attended the Mobile Air Conditioning Society's 2014 Training Event and Trade Show in New Orleans last month. The main topic of discussion was R1234yf, or "twelve-thirty-four" in A/C lingo. There has been a lot of hype about the changeover to this refrigerant. Don't panic. The reality is that it...
Four Seasons was recently honored with the "Most Innovative New Product" award for its Deslugger compressor clutch timer during the 2014 Mobile Air Conditioning Society (MACS) Worldwide Training Event and Trade Show, held in New Orleans, La.
The purpose of oil balancing is to make sure the amount of oil in the A/C system remains at the correct level. The first thing to consider when performing the process is the amount of oil contained in the replacement compressor. This can vary from a full charge of oil...
The A/C compressor is a pump that compresses and circulates refrigerant within the A/C system. Some have pistons inside while others have rotating vanes on an eccentric or a pair of metal scrolls or spirals around an eccentric. Many late-model vehicles have "variable displacement" compressors that change the piston stroke...
Working technicians will be educated on a variety of important service and repair topics when they sign up to attend a 2014 MACS Mobile A/C Update clinic.
If you receive customer reports on Model 209.372/472 vehicles of a groaning noise and vibration felt in the steering wheel at engine speeds between 800 and 2,000 rpm and with the A/C on, the cause may be the transfer of vibration from the A/C compressor through the high-pressure power steering...
HVAC systems differ from one hybrid to the next, and some systems have used a scroll compressor, which can be powered via a belt when the engine is running, or electrically when the engine is off. Most of the newer hybrids have changed to an inverter compressor, which is a...
Four Seasons has added its A/C compressor installation video to its YouTube channel in an effort to provide professional technicians with educational opportunities to help maximize their time. The training video provides an overview of the various steps involved in replacing a mobile air conditioning compressor.
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.
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.
