I had an issue with my laptop not booting up correctly. I found A1 Computer Service through a cursory Yelp search and chose them since they had earned multiple five-star reviews recently. I called in about the issue. Bob, the person with whom I spoke, was very patient and courteous. He informed me about what could have caused the booting issue and about the pricing to fix it. He was very prompt in communicating with me the available times I could drop off my laptop.
He was able to fix it within a few hours on the next day! He even helped me update some applications on my laptop and optimized it so that it runs faster than before, at no additional cost! Bob was very polite when I met him and very responsive to my questions about my laptop. If I could give more than five stars, I would! Also, PLEASE visit the A1 Computer Service website for details on appointments, services, location etc. BEFORE visiting or even calling.

Drove 30 mins to shop to find out they are open by appt only. Nice. You'll likely be told if you have a crack screen on a touch screen laptop that its not cost effective to repair/replace the screen as the probable cost if replacement including labor is estimated at $400.

I have a touchscreen laptop so when it cracked on the corner I was worried about the prices and if it could be fixed at all. Fortunately for me I found A-1 Computer. I first picked them of course because they have good reviews and they have been in service for more years than other places I had checked out so they were way more knowledgeable as well. My experience with them was 5+. They respond right away and know what they are talking about and dont tell you a bunch of stuff just to get a client.
I truly felt I was being told the best options as well as more than one option so I wasn't stuck. I also told them how I didn't have the funds until after the holidays so they also told me another option that would fix the screen but also save money. I highly recommend this place. The people are very professional and respectful/polite. Very upfront about pricing and how long everything takes. I will continue to go back to them whenever needed.

Bob was knowledgeable, professional, and a good value for the services provided. I feel that he is fairly priced for the services provided, and I was even able to purchase spare parts from him as well.

Very rude when I called for a quote and wouldn't even let me speak! I only wanted to know his hourly rate but he kept going around the question and talking over me then hung up on me :
