Pros: - David was great at assessing the situation and being able to test out the doorbell I needed him to install - great communication and was able to come help me out the next day. Was on time and worked quickly. - charged a fair price that's to standard Cons: - didn't really have room for negotiation but price was fair Overall, very happy with the work and results. Would recommend! read more

Managed to get David on an off day. He needed to come by to see what he could really do. I was interested to get Ethernet pulled from my basement to my wire closet. It came quickly. Measured. Realized there was no internal way to get the cable down rather had to come up the side of the house through the bedrooms. Not ideal but now I know. He was patient and knowledgeable through the process. Now let's see if I have to get starlink or frontier. read more

Zion Av installed a 65" Lg C1 in a Mantle Mount over my fireplace. They ran higher end optical hdmi cables, expertly run through panels in the wall. Power and speaker wires for future use were also installed. The protect went perfectly, we ended up with exactly what we had envisioned. They were responsive and knowledgeable and I plan to use them for future projects. read more

Great to deal with. Super responsive. Very reliable. Very glad to have discovered Zion AV. You can't go wrong with this service. Just give them a call. read more

We moved to a house with an old AV system, some working and some are not. We hired him to improve our internet access, make our AV usable, get all the speakers around house working, move and mount TV and sound bar, fix projector, screen and sensurround audio system. David is professional and prompt. He took the time to diagnose the problem before giving us a quote. We work from home so it's very important that we have good internet connection and David is able to work with our schedule, giving us heads up on when internet will be down while he is working on it. He is very patient explaining what needs to be done, why we need and how much will it cost. He was nice enough to let us try some products before we buy. We didn't end up buying some and there is no pressure at all! David works hard and plays hard too. I get to know the guy on a personal level. When I first reached out, he said he can't make it to our home until after 2 weeks. Since AV is not emergency, this is not a problem for us. We were glad we waited to get the right person to work on our AV system. Highly recommended. read more

Dave is awesome! Highly recommend him! With all my frustrations with Comcast, I finally looked on Yelp to see who could do a wall fishing job as I wanted my TV above the fireplace. I called him at 5:30 PM on a Wednesday, and he was at my place by 8:30 PM that day, as he had promised. He took a look inside my place, finding wall space, and said he could do the job easily. He stayed within my budget which I was grateful for. Also, he noticed Comcast had given me an old crappy cable box, and recommended me to get a HDMI one. I went the next day, and got a nice sleek box that's half the size! Dave came 2 days later, and did the job within an hour and half easily. Although I was not there, my brother kept me posted. I spoke with Dave during the job, and he mentioned Comcast did a horrible job with the internet cables and splitters, tech-y talk that I don't quite understand, but basically re-did it for faster internet connection at no cost. How awesome is that? I did read how he is not on time and such, but I had no problems. The most he'd be late was 30 minutes, but he did give me an hour long time frame of when he would be by. He also picked up his phone everytime I called, so I had no issues at all with working him. For any AV needs in your home, call Dave at Zion! read more

Good company but didn't use cause of their cost was more than expected...sorry But needed so.ething alil more affordable to my budget read more

I have reached out to David on 2 occasions for mounting 65" TV (one OLED and one LED SMART) . My experience has been great, David is very prompt in responding and very professional in his work. Highly recommend read more

zion av did an excellent job running ethernet cables behind existing drywalls from the 1st to 2nd floor in an old townhouse - they did a very clean job and it's working very good read more

I don't do negative reviews lightly. David is NOT an honest business person. He stood in my living room after giving me an estimate of 2 hours and $800 then 5 hours later my tab was $1000. That's his estimating deficit and shouldn't be mine to pay for. But I did write the check because he also said (as he stood in my living room) he guaranteed his work and provided a one year warranty for all services. The type of work David does leaves most people dependent on him. HIS PROGRAMMING OF MY UNIVERSAL REMOTE DID NOT WORK AND STILL DOESN'T And he did NOTHING to fix it. - except imply I or the original installer was the problem. After many attempts to have him honor his warranty/guarantee, my emails (as recently as last week) continue to go unanswered. When he did respond to my first detailed emails the exact and specific issues he didn't acknowledge he might have made mistakes. He said "you have the software, here are your crappy files from before I programmed it." He didn't call or offer to come over to fix it. His attitude is about him making a buck and not customers. STAY AWAY. I am still having problems. He bashed the guy who installed my stuff originally. Well he at least cared. David, you did what amounts to stealing from me. There are special places for people like you. read more

I had enough of Comcast raising my bills and wanted to get over the air broadcast. I called a few antenna installers. Dave seemed most knowledgeable with what antenna would work well. I procured it from Amazon. Dave said there is no difference in cost should he get it either. Scheduled an appointment for 1st week June. Dave came as scheduled, surveyed the house first, procured the necessary brackets and did the job in a couple of hours. He cleaned up very well after that. His price was very reasonable. It's been a month since I got the antenna installed and I am enjoying the quality of over the air reception. I highly recommend Dave! read more

After deciding to install a flat panel TV and home theater and extend some home networking, I came to yelp to locate a contractor. Zion looked really good with all the 5 star reviews, so I thought I would give them a try. I called David last Friday and explained what I needed done. David asked if he could come over later that night and I said that I would be available after 7:30, David said okay and that he would be there at 7:30. After getting back from the Gym, I got a message from David saying that something had come up and that he was sorry and wouldn't be able to make it. He then asked if we could meet at 12:30 the following day, I said sure. The next day I came home for lunch to meet David and he pulled a 'no-show'. I called a couple times at 12:45 and 1:00 and there was no answer. I finally messaged him later in the afternoon asking where he was and he messaged me back that he was sorry and that he should have called and that there was some family stuff going on... David then said he would like to call me later that day or the next day to evaluate the job. I said fine. To make a long story a little less long, David didn't call me back later that day, nor did he call me the next day. At this point I was really anxious to get all my equipment installed so I called another contractor (check my reviews) and that contractor came the next day, upgraded my wired networking, hung my flat panel display, installed my home theater and even stayed to help me finish building my entertainment center! (That last bit was off the clock!) With all the great reviews David got, I'm sure he's knowledgeable but I have to rate him very low on dependability. My time is valuable and I don't have time to waste on cancelations and no-shows. read more

Pro: picks up your call and comes on time. He did cleaned up stuff afterwards. Cons: really over priced for the the quality of work. Asked him to install tv and sound bar wit concealing all wires, he kept sound bar wires visible. He was not willing to put an extra nut. I had to tight couple of nuts in tv frame after he left. He constantly tried to sell his hdmi cables at extreme rate of $50. I can get best quality hdmi for $10 in frys. His website has 10% discount offer. When i asked for this discount he made face like i asked for his kidney. I would not recommend. But i dont have experience with any other so i dont know if others are better or worse. read more

I called David for a quote and he took the time to educate me about the process and the considerations behind hanging a TV on the wall. Although I decided not to just buy a stand instead, I wanted to write this quick note as a thank you for David's time. If I were to hire someone, David would be the man. read more

OK so I know that TiVO and cable really are not considered IT services, but that shit is confusing--especially when you have ComCast cable guy come over and "fix" everything for you so nothing works; then they blame it on your TiVO box. OK I digress, had problems with my TiVO and cable set up after we moved; ComCast bailed out with their lame excuses so I had to take matters into my own hands. I tried to find someone on Yelp but had no luck, so I went to Craigslist.com and found Zion AV; left an email at about 10:00 pm and had an email from Davie by 7:30 am the next morning. We dicussed his rate: $100 bucks for the first hour and $60 an hour after that, and the time he would show up. He was on time and had my stuff rewired and working within 30 minutes. He was great. If you have any home networking needs here in San Francisco, give them a call. read more

Called these guys on a wednesday morning and was impressed that they would be able to schedule me in so quick, just 3 hours later. He kept me updated via iMessage as he got closer to me and was prompt and actually a bit early when he got to my place. Very impressive! Service was quick and professional, he quickly assessed and understood the situation as I described it, and was able to quickly get my network set up exactly the way I wanted it. You can tell Dave really knows his stuff just by the way he approaches problems and diagnoses issues. The price was also very reasonable. After he left I discovered that my internet had stopped working. I quickly called Dave and he returned in just 10 minutes to diagnose the issue. He quickly resolved it, and gave me some tips on the best way to set up my network. Everything is running perfectly now. What a great experience! Highly recommended. read more

It's difficult to convey to the fullest extent the excellent work Dave did for our home theater project. We initially hired him to install a wall mounted large screen LCD and surround sound in our family room and a smaller LCD in our bathroom. His prices were reasonable, but more importantly his quality of work and professionalism were unsurpassed. An added bonus is that he is actually also a really nice guy. In addition, because we liked his work so much we also asked him to take care of all the connectivity and wiring issues with our CAT5. In the end he wired the house at specifically requested outlets for data, installed wi-fi for the house and an additional wi-fi booster to reach the backyard and garage. Furthermore, at the same time we had a certain satellite TV company come to the house for installation and Dave worked with the company, both in person and over the phone, to make sure we got what we wanted from them. He also made sure that the satellite company's hardware connected flawlessly with our home system. To summarize, Dave (Zion AV) is knowledgeable, professional and considerate. He will go out of his way to make sure your project is completed to your satisfaction. He can help you with not only your AV needs but also all home connectivity issues. read more

Orders my TV from Amazon on Cyber Monday. Was scheduled to be delivered on 12/10 and I set up an appointment with David for that evening. With holidays he was booked solid and made time to get me into his schedule. At the last minute I had to cancel due to the TV not arriving (another story for another day). It finally arrived on 12/12 in the morning and I called him back. He was able to get me in that evening and everything went according to plan. Thanks again David! read more

Wow! Dave did a great job mounting a large 4K tv for us. This was a complicated project, mounting over a fireplace and new electrical wiring and cable indoor/outdoor and under the house. Dave was prompt, meticulous, got the entire job done in one day and kept everything clean. If you need a reference, have Dave give you my name/number. You'll be happy f you use him for your A/V needs. M. L., San Carlos, CA. read more

David was a pleasure to work with! I hired him to do some work for my office, including re-wiring our video-conferencing system, installing a new Shoretel phone system, fixing existing phones, and repairing our fax machine. David completed every task perfectly and with ease. He explained everything to me in simple terms and everything has been running perfectly smooth for the last couple of months. The only thing that's kind of a bummer is that he is usually very booked up so sometimes it takes a week or so to get him into the office. David is professional, efficient, extremely competent, has reasonable prices, and easy to work with. I definitely plan on hiring him again. read more

Dave was awesome figuring out the issue with our AV set up in a large school setting. He was not only fast in his communication but very easy to work with, knowledgeable, and very transparent about costs. We'll continue to use Zion AV for future tech needs around campus. read more

Dave came in and rewired some unfortunate and sloppy home networking done by the original builders of our condo. he listened to what i wanted, assessed the situation, gave me an estimate, and then completed the job. all along the way, he did not mind that i was snooping and asking questions. he was very accommodating and taught me a few things along the way. i am so happy that i finally do not need these 100 ft cables snaking around my place (do you seriously think i'm going to play halo on my xbox with a wireless connection?). great work. knowledgeable. good guy. worth every penny. read more

I did quite a bit of comparison shopping before picking a company to do install my flat screen on the wall. I found Zion AV through yelp and after a series of due diligence questions I had Dave come out for the install. He did a fabulous job of installing the TV very quickly with great finished results. A few things to note: Dave included the wall mount in his price (The Sanus wall mount used is the best) Also, Dave uses a power bridge to wire the TV to your power supply (this way you don't have to run any hot electrical wiring. Great way to do it. Do yourself a favor and call Dave for you A/V needs. read more

I hired Dave to do some low voltage wiring in my office that I was having built out. Dave was an extreme pleasure to work with. Dave was very professional, honest, and very knowledgeable about what I was looking to do. During the time Dave was working on the low voltage work, there was a lot of other construction going on that wasn't ideal for his working condition, but under the circumstances he made it work. Dave not only installed all the wiring in my office for phone lines and internet, but he also set up my router, firewall, networked 8 computers, networked my fax machine and 2 printers, connected Comcast, set up my credit card machine, helped install 3 flat screen TVs, set up speaker wire for my 6 ceiling speakers, installed the speakers, and wired 2 amps to run the speakers. Needless to say Dave did a lot of quality work in my office. I highly recommend Dave at Zion AV due the fact that he is very honest, friendly, competitive in his prices, and is a hard worker. read more

I needed the speaker wiring totally redone in my house for surround sound and zoning. I also needed new rear speakers installed, new outdoor speakers and my TV wall mount adjusted from the horrendous job I tried to do myself. I also wanted wires hidden to make the house look pretty. Finally I didn't want to go to a specialty store to get this done, was looking for a more personal touch. I found Zion AV on Craigslist, called the number and was able to set up an appointment with Dave on the same day. After a short consultation, Dave knew exactly what needed to be done, made some very good recommendations above and beyond what I originally envisioned, and had a very reasonable quote for me later in that day. The work was scheduled promptly, the team arrived on time, and was able to do the entire job in just one day. They were totally trustworthy, and I was very comfortable letting them work in my house all day while I was at work. They not only completed the hardware installation, but Dave took extra time to help set up all the components for optimal sound and video quality. They even left the house nice and clean when they left. Personal service, reasonable price, excellent quality. And the sound system now just plain rocks! Couldn't have asked for more! I highly recommend Zion AV for their services. read more

I wanted to wall mount my LCD tv and tried to do it on my own ... Fixing the wall mount bracket to the studs was tricky and decided to seek professional help. Called Zionav at 9 am and I get a call back from David in an hour. Scheduled an appointment for 2 pm same day and got the job done .. neat. David was friendly and he gave me further tips on optimizing the wiring and connection points for all the networked gear. Certainly recommend him for all your tv/speaker installation needs read more

Dave, who owns Zion (it's a one man show) is fantastic! I needed three things done to my place: Stereo speaker wires run under the crawl space and through the walls, ethernet cable run under the crawl space and into my den, cable TV cable outlet moved from one end of my den to the other. Dave was not only less expensive than other electricians and handymen, but I believe, much, much better. He gave me a fixed price quote, but beyond just doing the work that he was asked to do, he also really knows his stuff, and gave me a bunch of recommendations for better ways to set up my stereo itself. For example, he put in a new cable to my system, and actually then spent the time (without charging more) to reprogram my surround sound. Wow! I cannot believe how good it sounds now -- infinitely better than before. Throughout everything - from estimate to completion of work, I felt like Dave was completely honest with me, wasn't trying to take advantage of me, and sincerely cared about arriving at the best solution for me. Dave is such a breath of fresh air in a world where so many of these guys either don't know what they're talking about, or are trying to shaft you and cut corners everywhere they can. read more

I highly recommend Dave of Zion AV for all your Audio-video related work. He is a great guy, very professional and great attitude...unlike some of the other silly "Mr Audio Videos" I found on Craigslist. I needed a home theater set-up, Dave came with the right accessories and set up the whole thing in a couple hours. I am very happy with his work and will also recommend him to all my friends. read more

Dave of Zion AV is a competent professional in both technical knowledge of home theater specification, installation and set-up. He is very personable as well as an astute businessman. We used his services to install our new 46" LCD HDTV as well as mount speakers (fronts and surrounds) in the wall and ceilings. Dave got us a great deal on a Yamaha receiver and set the system up after installation. It really ROCKS and so does Dave. It is refreshing to see such a bright and competent person who is running his own show at a relatively young age (I'm middle aged). I highly recommend Zion AV read more

I called these guys today after reading so many rave reviews. I also saw they were advertising $125 TV installation. However, when I told him that the TV size was 65" he said it would cost $200 instead. There is no mention of the TV size limitation on their web site. It is not that I was getting an industrial size TV installed. Needless to say, I feel they are not very truthful. So be careful. He may be doing a good job. It is not a rocket science. I will hire someone else to do it. read more

Updated Review: Dave did some network cabling for me and sold me a Panasonic VT30 65" TV and mount/mounting job. The network cabling job was decent, but not fully tested, and required me to have him return to finish the job when I tested them on my own. For a total of 12 ports he installed, you'd think these could be tested pretty easily. In the end it was completed and worked okay though so I don't really ding him for this on my review. What I do penalize Dave for is pushing his stupid extended warranty scam onto me. Hoping that Dave was a trustworthy guy, I bought a "Repairmaster" extended warranty for the VT30 through him for several hundred dollars which he claimed at the time would cover any problem and replace the TV if necessary at no charge. Last week one of the rear fans on my TV started buzzing horribly. I thought great I have my warranty let me get that out and use it. Upon calling Repairmaster I was placed on hold for over two hours without anyone answering. In this time I started searching online and finding out how essentially almost everyone who ever purchased one of these warranties has reported the same experience. It seems that Repairmaster has engaged multiple vendors to resell their scam warranties to customers. They then share in the profits and no one is the wiser until the customer calls in for service and gets laughed away. I wrote Dave an email about this and was told that the warranty service "sucks" (his words) but that it was not a scam and I should have called him to fix my TV. Thank you Dave for selling me something that you think sucks. To all of Dave's other customers - I would strongly advise researching anything he tries to sell you. Maybe ask him things like "Do you think this is junk you are selling me?" Because clearly anything that makes him money is enough for him to screw over his customers... read more

After reading all the great reviews about ZionAV I decided to inquire about his service and emailed him for a HDTV antenna installation. A day goes by no response so called Dave instead, no big deal. Dave immediately picked up the phone and answered all my questions . I scheduled an appointment with him the following Friday at 3:30pm, as he says this is the earlist time he has available. I preferred the weekends but he was booked. I didn't want to take the day off from work as the last quarter of the year is usually busy for me instead I was able to work something out with my company so that I can leave work early. Friday came and got home a little before 3:30pm but didn't see any car in front of my house so I gave Dave a called. He told me he won't be able to make it and we need to reschedule!! Thanks for giving me a heads up. I understand that everybody is busy but if you can't stick to your schedule at least have the decency to call your customers or potential customers to let them know ahead of time(at least a day). First impression is very important and Dave blew it this time. I'll have to look somewhere else that is more dependable. read more

To add to my previous review: He was out on vacation and called me actually about 1.5 weeks later. Not ideal. He was very efficient when he came and fixed our problem. I called them three days ago and left a voice message. I emailed them two days ago in case they didn't get my voice message. Nobody bothered to call me back or respond in both instances. If they can't return my call for an inquiry, I can't imagine what the customer response would be like as a paying customer. read more

We've used Dave's services twice now. First time was a few years ago to mount the flatscreen over the fireplace. Second time was two months ago to install the surround system. While I'm not the technologically savvy type of electronics fanatic like my husband, I am in charge of keeping that arena in line with the budget. Or as I like to call it, reality. We told Dave what we were looking for (actually, I should say "what the husband was looking for") and he gave us the good, the bad and the ugly of mounting a tv over the fireplace, the issues involved, the costs and esthetics. I was picturing an end product with holes in the wall and wires hanging out for all to see. What Dave gave us was a look that was totally clean, inconspicuous and PRACTICAL. You'll see the wires if you look really really hard. It looks niiiice. Although we didn't buy the tv he recommended (sorry Dave, but Costco was my reality here), we did end up buying the sound system from him since it was a better product than what the husband had in mind. Plus his pricing was very competitive. Better stuff AND cheaper? Yeah, my reality issue is appeased. Dave even went the extra mile and programmed our remotes for us. ALL of them. Husband hasn't had any of the communication problems mentioned in the other reviews. All in all, we got the most bang for our buck with Zion and we'll be talking to Dave when reality leads us to our next project. read more

Dave is completing my family room av installation as I type this review. He is the only person I called based on yelp reviews. I called a little after 6 pm on a Monday and he called right back to accommodate me on.the Friday of the same week. He had a very professional yet friendly demeanor. His enthusiasm to do things the right way and not cut corners is greatly appreciable. He had to make multiple trips underneath the home into the crawl space to drill through the baseboard and pull wires for 5 speakers, 2 subs and a Tv. The full job took more than a day and a half to complete and the second trip was from 5 pm to 10 pm the following Wednesay. The good part is that he did not leave me without a functionng system when he had to wind up the first day (Friday) job. Everything with the exception of the surr spkrs were plugged in and working. He even agreed to put in a recessed receptacle for the refrigerator without hesitation as an add on job. Of course I paid for it at the end of the day. Dave has great attitude and even at the late night hour didn't wink for a second when I reminded him of a small leftover item to trim the sw cable. It's not everyday that we come across professionals that perform not just their best work but deliver an exceptional customer experience. At the end if the day, although it cost be about 30% more than the original quote and quite frankly more than I had hoped, he did a great job, and to his defense put n man. Stars I asked forin the former bonding posts on the wall, 20' ft professional HDMI cable and an additional subwoofer outlet and Cable. What's more, he even said he would come back and fix a bad power outlet that was covered up by the prev owner of my home in a very shabby way. I would call Dave again in a heartbeat if I needed any av help. read more

Are six stars possible? If I could I'd give Dave at least six. He came out today to run wiring for my home theater sound system. He was very thorough, knowledgeable, very reasonably priced, and a pleasure to work with. I've dealt with many contractors and Dave is just the best. He took additional time to make sure everything was just right and went above and beyond by organizing and securing not only his wiring but also Comcast and the phone company's messy cables too. He also spent extra time to do the audio set up for me and tested everything. He answered all of my questions and had great recommendations for me. I highly recommend Zion and I will be using Dave for my business needs as well. Zion is quite a find! Thank you Yelp! read more

Dave was great!!! We have a complex system in our living room, it has always been buggy and after it being out for 4 months and getting no help from original installer, we found Dave on Yelp. He was quick and professional, diagnosing this was more than just being buggy, ordered the parts we needed and then came back and installed them. The best part was that he then reprogrammed our remote control, and that has made such a huge difference!! Looking forward to using them for all our AV needs. read more

Dave just finish an install of 2 TVs in my house. He's fantastic - he did a great job, was very polite, professional, knowledgeable, and thorough. His rate is better than Best Buy and some others I checked out through Yelp, and we couldn't be happier with his work. I called him this morning and by this evening we were watching TV on our brand-new set. I'd recommend him any day. read more

Dave of Zion AV is fast, responsive, and very knowledgeable. Best of all, he knows what he's doing. He installed outdoor speakers on my patio and connected them to my receiver. Even though my house had a small attic and a cross beam blocking the route from the speakers to the receiver, Dave made it work. He also ran a phone cord from my DirecTV DVR through the crawl space underneath the house to my Internet router so that I could access OnDemand. If you need to set up some electronics at a reasonable price and have a trustworthy guy do it, Dave is your man. read more

I called Dave to have a new plasma hung on the wall, get new speakers, and have them installed in the ceiling. Dave came right over and after we discussed our options, we decided to just buy new speakers and have them installed in the ceiling. Dave was very patient as we took our time making a decision and was flexible in scheduling the installation. On the day of the installation, Dave encountered several issues with the spacing and placement of the speakers. After a full day of trying to make it work, we finally came to the conclusion that in-ceiling speakers were not viable. Despite the frustration of not being able to do the job we had originally planned, Dave was very good about laying out other options and then working with us to make it happen. At the end of the day, we didn't get what we originally planned, but we are happy with the final result. I would definitely use Dave for my future A/V needs. read more
