Does the phrase "hybrid fluid maintenance" scare you? It shouldn’t. With more than 3 million hybrids on the road, and many of your customers considering purchasing one, servicing hybrid vehicles is in your future. Some special procedures must be followed when working on a hybrid.
The attention-grabbing headline in the world of air conditioning is usually the switching of refrigerants as the industry and regulators continue to search for the next level of environmental friendliness. But the underrated A/C story that's slowly developed during the same time period is the overall improvement of A/C systems.
According to the agency, a proposed rule will be issued this summer to withdraw approval for 134a for use in new motor vehicles and as an aerosol in consumer products. EPA pointed to the availability of substitutes for 134a in both motor vehicles and consumer products including 1234yf, which was...
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...
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...
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...
While Honeywell's recent PR efforts have been focused on refuting the concerns over the safety of its new refrigerant, this week the company has reported that a new study has found that its low-global-warming refrigerant, HFO-1234yf, has a global-warming potential (GWP) four times lower than previously calculated - below that...
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.
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...
Buying a new refrigerant Recovery/Recycle/Recharge machine can be a bit overwhelming. The item is expensive and complicated, and there are a lot of choices out there. Each manufacturer has a compelling story to tell about why its machine is the only logical choice. Hopefully the following article will help you...
