‘13 Civic EX, 1.8L direct injection: 115K miles. First warm day today and when I turned on AC max cold, high fan, recycled air I got barely any cooling even after 5 miles. AC has never had any maint. Or even recharging and always worked great the first 6 years living in Florida. Now live in upstate NY. At idle, turning AC on and off has NO EFFECT on idle rpm.
