00:00Many people don't understand, trucks already have air conditioning.
00:03So why do drivers spend money cutting a hole in the roof to install another one?
00:06This isn't redundant at all, it's about saving long term costs.
00:09Most factory truck air conditioning systems work fine, but with one limitation, they only
00:13operate when the engine is running.
00:15For long haul drivers who want to keep the cab cool while resting, the only option is
00:19leaving the engine idling.
00:21Short term it seems fine, but long term idling wastes more fuel, increases carbon build up,
00:26accelerates engine wear and raises future repair costs.
00:29So many drivers choose to install a parking air conditioner typically mounted on the cab
00:33roof powered by the vehicle battery or auxiliary power source after the engine shuts off.
00:38This keeps the cab comfortable during rest stops, without running the engine, reducing
00:42fuel consumption simultaneously.
00:44But many people wonder, does cutting a hole in the roof affect structural safety?
00:48The process isn't random cutting, workers avoid reinforced structural areas of the roof
00:52in advance, treat the opening against rust, install mounting brackets and
00:56apply sealant preventing water leaks.
00:58Properly positioned and correctly installed, it generally doesn't affect cab structure.
01:02However parking air conditioners have one weakness, they consume significant power.
01:06Insufficient battery capacity or extended continuous use can leave the battery too drained to
01:11start the vehicle next morning.
01:13So this seemingly simple rooftop unit actually solves the balance between driver comfort, fuel consumption
01:18and vehicle value.
01:19Also to need, contribute to child care, to support the vehicle clearance.
