I was awoken Friday morning at 6something by my home fire alarm system going off- LOUDLY.  The only way to shut the thing off was by flipping switches at the breaker box.  The old smoke detector upstairs had given us signs that it needed to be replaced.  This was it's ultimatum...\n\nAfter calling 2 electrician I was \""referred to\""...\n-the first never returned my call\n-the other sounded novice with respect to fire alarm systems\n\nI then turned to an online search with led to YELP.  After searching for electricians in the Mesa area, I came across \""Good Guys Electric.\""  I loved the great reviews and thus gave Mike a call.  Not long after leaving him a message, he returned my call.  He was patient when I gave him the \""detailed\"" version of my problem.  He then quickly explained what the problem was and told me how to fix it.  Afraid of getting electrocuted or such I told him I'd prefer it being professionally done.  He seemed understanding and looked at his schedule.  Of course he was booked solid next week.  He then asked if I'd mind him coming over later in the day sometime next week, after his last scheduled appointment (he knew and cared about my concern having to leave the power switched OFF in the upstairs part of our home).  I thanked him for being willing to extend his work hours.  I gave him more info and the call ended.\n\nA few minutes went by and I kept thinking about his advice on how to solve our problem and his statement that it should be an easy fix.  Next thing you know I was in the car heading to Home Depot.  I received more expert advice there and about an hour and a youtube video tutorial later, my new alarm was fully installed and working!  \n\nThank you Mike for being SUPER HONEST, helpful, and willing to lend expert advice to a frustrated home owner!  This problem is solved! but, if we need an electrician in the future, we'll be giving YOU a call!  :)\n\nThanks again!
