I had my computer in a big truble. Natan, the owner gave a professional advice and fixed in one day. The bill was very reasonable. I will use here again.

Natan was an immense help in finding out what was wrong with my computer and explaining everything to me so I understood. He is very personable while at the same time retains an extremely degree of professionalism in how he conducts his business.

Natan was awesome. My daughter had poured bubbles on my work laptop and Natan was able to fix and replace all damaged parts in a quick turnaround fashion. He’s highly recommended in my books.

Amazing experience, great personality and fast and good work. Dropped my laptop and broke my screen. He tested the laptop to make sure it worked and ordered the part. Fixed it as soon as it arrived. Highly recommend!

Brought in 2017 Apple laptop in. Apple wanted $650 for diagnosis and repair. We suspected a motherboard. Brought to Natan he was professional, gave me a detailed explanation with options to repair or to buy a new laptop. We ended up repairing the laptop and so far been great. Much cheaper than Apple and quality service with warranty. Def worth checking him out.

Had a problem with my computer's speed and my emails. Natan the owner took the time to explain to me what was wrong and the best way to solve the problem. He ordered me a new hard drive and two days later he installed it transferred my data, replaced a bad fan and installed a new email program, all in a few hours. Very reasonable also.. Needless to say I highly recommend using this company for your computer needs.

Natan was professional, responsive, gave me information on a range of options to fix my computer needs, and never pressured me. He fixed my laptop very quickly and it works beautifully now, all for very reasonable prices. Highly recommended.

After my kids left my laptop on the couch; it apparently overheated. Unable to get it started I brought it to Natan. 24 hours later I type this review on my repaired laptop. Great job, service and price. If you don't go here for your computer needs YOU ARE WRONG.

Not a great experience. The owner seems to do what he wants to do with your computer and neglects the needs if the customer. The work performed not only did help the problem it made it worse.

I took my virtually dead HP laptop to Commack Computer, fully expecting it to be relegated to the expired pile. Natan gave me an honest assessment that, due to its age, it may never work again and if so he wouldn't charge me.
Normally I might not have gone further but this laptop had sentimental value to me. So even as a paperweight I know I would have kept it.
Well here we are a few days later and my HP laptop is back up and running beautifully. If anyone has told you that you're PC, laptop, etc is toast then do yourself a favor and take it to Natan. I think if anybody can do it, and

The bad news is I need a new computer.

The good news is that I didn't have to pay for that information!

A few hours ago I brought my computer in for repairs. The man(we went right into talking shop, lol. I'll update later with his name.) there was helping another customer and his wife. He explained things clearly and honestly. After a few minutes I knew I had made the right decision bringing my computer there.

Once he had helped them and they left, he took a look at my computer. It unfortunately kept freezing. He tried running a diagnostic on it but it froze yet again. He explained

This guy was AMAZING. My wife laptop (3 years old Dell, good specifications) start doing crazy things. looking by reviews, we brought it to some guy in Selden, who was really sweet & friendly - and bad professional. After the third time he made another crazy diagnosis, we moved to Nathan, even though it was far (we live In Mastic Beach). He heard my wife story - and just by the story immediately said: its not virus, but the hard drive!. We left the store, after 2 days it was ready - work like new - and for great price! this guy is phenomenal!

Natan is fantastic. He is nothing short of a miracle worker! He fixed my daughter's computer after she spilled water on it, and got it back to her in time to go back to college...3 days including a weekend. Pricing is more than fair and he genuinely cares. Highly recommend to everyone.

Hey, do you want a kid fixing your expensive laptop or someone who had been in the business for years? For me, the choice was easy: I took my MacBook to Natan and he turned it around sooner than he had promised to. He takes the time to listen to your concerns and with critical data at stake that's important. I'm very glad I found Commack Computer Repair.

Brought a PC into Natan that was in dire need of a hard drive clean-up, moving files to an external HD, virus and malware removal, etc, etc, etc.... Left PC with him for a week while I was on vacation and when I came back PC was better than new! Only person I will go to for ANY PC issues going forward. Natan took time to explain several options and prices - and tried each angle to save me money, time and headaches. The BEST.

Hallelujah! I went to Natan after going to two other places to fix my computer and finally my computer is like new. Best part is, his price was cheaper than the guys who couldn't fix my computer. If you want affordable and reliable service than see Natan at componline!

I saw Natan, the owner at the businesses ai his new location. He quickly diagnosed the problem as broken connections to the motherboard. He gave me an estimate and said that if the repair didn't work, I would owe him nothing. The computer woks fine,and he gave me a six month's guarantee
