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...
