Maybe you should try the big orange box store. They're experts a cutting out the tradesman. You can do it, they can help. But by all means, don't call a qualified company to do the repair. They'd much rather be in the unemployment line than helping a DIY homeowner keep from doing damage to themselves or the equipment.
If YOU want change, YOU have to first change.
If you are waiting for the 'other guy' to change first, just remember, you're the 'other guy's' other guy. To continue to expect real change when you keep acting the same way as always, is folly. Won't happen. Real change will only happen when a majority of the people change the way they vote!
