No wonder compressor failure is so rampant.Hard to keep cool, and when your carвЂ™s air conditioning stops Air is 78% nitrogen and the compressor isnвЂ™t designed to compress nitrogen. And these are two crucial steps our AC guys never do. ItвЂ™s a disaster!ДЄC jobs are typically expensive for the single reason that it requires specialised equipment (especially for the evacuation and vacuuming steps). Not a single one of them owns a vacuum pump, yet they call themselves вЂњAC guysвЂќ. And donвЂ™t get me started with the home AC guys. That said, our car AC techs are doing a disastrous job in this country. The power of the vacuum pump (1/4, 1/2 HPвЂ¦) in use would determine how long it takes to pull the required void. IвЂ™ve seen procedures that require pulling down to 500 microns as the more reliable way to pull the proper vacuum, as opposed to vacuuming for a given amount of time (30+ mins) and then reading off -30 on the manifold gauges. I observed you didnвЂ™t attach a vacuum meter to the service line (or, rather, a service line with a vacuum meter attached). The oil will be sucked in with the refrigerant during the charge process. ND-8 oil is the specified oil for the 2003-2007 Accord.Дisconnect the service line from the manifold gauge and add the recommended PAG oil volume to the line. Each manufacturer lists type and amount of oil to add in different scenarios. If repairing a leak, for the 2003-2007 Accord, Honda recommends adding 25mls. If you evacuated the system, the rule will be to return the amount of PAG oil drained. Add compressor oil (PAG oil): There are specific volumes of oil to add based on the work done on the AC system. If the vacuum drops again then thereвЂ™s a leak that should be traced and repaired.Д§. If the vacuum drops, vacuum the system again and observe for another hour. Testing for Large Leaks in an AC SystemДЄllow the the setup to stand for an hour, on an AC system without a large leak, the vacuum would remain at 30inHg and not drop. An AC refrigerant scale would be the best.ДЄfter 30minutes have elapsed, close both taps (high and low) on the manifold gauges and turn off the vacuum pump. Digital precision weighing scale or equivalent: Bathroom scales are not appropriate as they just donвЂ™t have the precision required.AC manifold gauge set (with high & low side couplers).Also, never pump compressed air into the AC system, the mixture of air and refrigerant can ignite! Safety goggles and gloves should be worn.ДЇinally, NEVER connect these small cans of refrigerant to charge through the high side.

Spilling or spraying of refrigerant into the eyes can cause blindness and on the skin frostbite. Safety Precautions for Air Conditioning work Charging by weight is more accurate as pressure can be affected by ambient temperature, thus, the service ports will read different pressures depending on the temperature of the day.

Simple.ДЄir conditioning systems can be recharged either by weight a specified weight of refrigerant is added, or by pressure refrigerant is added untilВ certain recommended pressures are reached for both low and high sides. My aim this time was to evacuate, vacuum and recharge the R134a AC system on my Honda Accord by weight. Furthermore, a mechanic had 3 years ago replaced the broken magnetic clutch for my compressor and didnвЂ™t pull a vacuum on the system before recharging it. Tests clearly confirmed it was low on charge.

My AC system had slowly lost its Arctic effect until it got to the point where it performed pretty poorly on hot humid days. I also cover why certain steps often omitted during AC work, should always be followed to prevent future costly repairs.

I did this recently and my cabin now feels like a trip to Antarctica! I detail the procedure for recharging an empty AC system going by industry best practices. Pulling off proper air-conditioning (AC) work by yourself would require some tools.
