Gee, I've been using Mario since 2012. He still deserves a solid 5! Our refrig is back in service thanks to him and his guy Bill. And his rates are great. One thing in particular - he charges a basic service call fee. Finds the problem and tells you what he needs to do and how much it will cost. If you have him do the fix, the service call fee is deducted...even if you decide a few days later.
