Hi, I really hate to hog this blog this afternoon but after my tire info request, I discovered from our air conditioning service people that our "refrigerant was low and the system has a leak in the evaporator coil" and that we either need to replace the entire system or put in a new coil (which he described as "putting a brand new engine in an old car")...I don't know anything about air conditioning ---- advice? Should I get a second opinion? Is there a Vero air conditioning co. that has been around for a long time and is consistently great!?
