Fixes mistakes, Provides honest diagnoses/estimates, has extremely fair rates, works w/tight budgets, insurance claims, etc. Prevents others from getting ripped off. Does it right the first time. Referrals come by word of mouth. Fixed my heating & my a/c once. The other guy kept coming back annually charging me each time.
