“In the middle of the worst heatwave in years, my air conditioner suddenly stopped working… I called AVS, and not only did they come out at 11:00 pm that very same evening, just a few hours after I called, they efficiently and professionally diagnosed the problem as a failed capacitor, replaced it, and had the air conditioner running again in just 15 minutes.” Rich, Google review
