How much refrigerant do I need for my AC lines?
The amount depends on your line length, diameter, and refrigerant type. Use our calculator by entering your liquid line size, suction line size, and total line length to get the exact amount needed. See also our Car Detailing Cost Calculator.
What's the difference between R-22 and R-410A refrigerant?
R-22 is an older refrigerant being phased out, while R-410A is the newer, more environmentally friendly standard. They have different densities, so the charge amounts differ even for the same line sizes.
How do I measure my AC line length?
Measure the total length of refrigerant lines from the outdoor unit to the indoor unit. Include both the liquid line and suction line lengths, accounting for any vertical runs and bends.
Can I add too much refrigerant to my AC system?
Yes, overcharging can damage your compressor and reduce efficiency. Always follow manufacturer specifications and use calculated amounts for line charging only.
What tools do I need to recharge my AC system?
You'll need manifold gauges, refrigerant recovery equipment, a scale, and proper safety equipment. AC work should be performed by licensed HVAC technicians due to environmental and safety regulations.
How often should I recharge my AC system?
