Rejuvenate your air conditioner! A 10-year-old system can be 20 to 30% less efficient than when it was new. A/C Re-New helps restore your air conditioner to its original state, saving you money every minute your air conditioner runs. It reduces costs with fewer operating hours and increased efficiency. A/C Re-New decreases friction within the compressor, silencing loud noises and reducing additional wear-and-tear on your system!
