AC blowing warm air? Low on refrigerant? Our EPA-certified HVAC technicians recharge R410A and R22 systems, detect leaks, and seal them properly — not just a temporary fix. 空调不制冷可能是缺氟，专业师傅上门加氟+检测泄漏，同时修复漏点，彻底解决问题。
| Service / 服务 | Cost / 参考价 | Notes |
|---|---|---|
| R410A Recharge 加氟 | $150–$300 | Includes leak check |
| R22 Recharge R22加氟 | $250–$500 | Higher cost (discontinued) |
| Leak Detection 检漏 | $80–$150 | If recharge not done |
| Leak Sealing 修漏 | $100–$300 | Depends on location |
| Vacuum + Recharge 抽真空+加氟 | $200–$400 | After repair work |
| R22→R410A Conversion | $500–$1,500+ | Coil replacement needed |
R410A refrigerant recharge costs $150–$300 including leak check. R22 (older systems) costs $250–$500 due to its phase-out. If a refrigerant leak is found, sealing it adds $100–$300. Total cost depends on how much refrigerant is needed.
No. Refrigerant is a closed-loop system and should not need regular refilling. If your AC keeps running low, there is a leak that must be found and repaired. Simply adding refrigerant without fixing the leak is a temporary fix that wastes money.
R410A加氟约$150-$300（含检测），R22约$250-$500。正常情况下空调不需要定期加氟——冷媒是封闭循环，不会减少。如经常需要加氟说明有泄漏，需检测修复漏点，否则加氟后很快又会不够。
