Great work by Harold to remedy my inside land line phone issues. Very nice to work with and communication to set up an appointment was A+. Highly recommend! read more

Harold was great, came on time, worked to get all my telecom connections running, and was right on track.

I called a few local companies I found on Yelp, but only 2 people called me back. One, said he was semi-retired and doesn't work in the City, but recommended Harold, and the other was Harold. It took a few days to get our scheduled aligned, but Harold was in communication and was updating me in terms of his schedule. In the end, we wound up resolving the wiring need internally, but Harold's promptness and customer service was so far and away better that I had to put a review on Yelp about it. I have no doubt that should I have another need in the future, I will reach out to Harold. read more

I already had Sonic.net for my DSL and my address was eligible for a bonded line at up to 100 mbps. The problem was that the wiring at my building's utility box needed some adjustments for Sonic to activate the service. Harold added a second pair to my line to connect to the IW. I also wanted to change the location of my jack inside my apartment and Harold rewired everything in a very stealth manner and connected new Ethernet jacks in three rooms in my apartment. The cat5 wiring actually looks decent the way Harold attached it and most of the wiring is out of sight. In addition to setting me up so well Harold was very friendly and answered all of my questions, a nice guy and great to work with. read more

I gotta agree with all these fine words about Harold--quick and able, friendly, efficient and resourceful. Our old house has oodles of bizarre wires running through it and he cheerfully crawled up onto the roof and down to the basement to assess the situation. We had all kinds of crazy ideas about the work we wanted, and though it meant less money to him, he convinced us that there was a simpler way to go. A real life superhero! read more

We're in the process of renovating our building and needed someone to re-route ethernet cabling connecting our work stations and server on the third floor to our shared printer on the first floor. It seemed like a pretty straightforward job, but presented some challenges with the layout of our building and the existing cabling configuration, which honestly was a total mess. I got a referral from our ISP, but their guy was a total flake. My next stop was Yelp, where I found Harold Day. Harold arrived exactly when he said he would, carefully considered our networking needs, figured out the best way to get things done, and executed flawlessly. He was also proactive by suggesting some things we hadn't considered. Thanks for the great service, Harold! And thanks Yelpers, for telling us about Harold. read more

I needed some phone wiring done in our house and found Harold on Yelp. He was here in about 15 minutes (since he was in the neighborhood) and done before I knew it. Fair price, great job executing and he has all the tools, which I don't have, for telecom and low-voltage wiring. For those of you with Sonic, he is also on their list of good techs, so he's pretty familiar with Sonic. I would for sure use again. read more

Recently moved into a new apartment off Mission and had Sonic.net DSL service installed - of course before realizing I had no operating phone jacks in my suite. Yelp reviews directed me to Harold, and I booked him the morning of my move-in day to troubleshoot and install a working line. For $75 plus a jack and cable, he worked a direct line into my apartment, and was a pleasure to work with. He entertained a couple ideas I had for installing the line, even attempting multiple options to make sure the optimum result was accomplished. Harold knew exactly what he was doing and helped me secure the fastest and most reliable Internet I've had in my life. I wholeheartedly recommend Harold and Sonic.net DSL to anyone fortunate enough to be within reach of either of their services. read more

Fantastic work and a fantastic guy. i have an older Edwardian, and have wanted to centralize the networking in the house. Other folks have had some weird suggestions, but Harold was open to finding alternatives and was more than up for tramping all over the house. Got it done in half a day, great price, and super-happy with the work. Waaay easier than i thought it would be. Thanks Harold! read more

Forget AT&T or Comcast! I found Harold Day on Yelp, and I'm adding my review to his growing list of accolades. My wife and I moved into a new condo that appeared to be wired with ethernet in all rooms. Except it didn't work. Harold showed up on time, assessed our setup, asked me a few questions, then walked through the pros and cons of a "quick and dirty" fix vs. a "real fix." He had everything working perfectly in less than an hour, and I gladly paid his minimum of $75 ($50/hour with a 1.5 hour minimum). Harold is the man I'll call next time we need any more telecom wiring work. read more

I needed a phone jack to be able to use sonic.net so I called Harold. It took me a while to get a hold on him but he fitted me into his schedule. He told me if he only needed to put the phone jack or something simple like that he most likely will spend 1.5 hour and that his rate is $50 p/h. Of course the bill would increase if he needed to order cables or other materials. So I said: Make senses! Cool, come to my house! He came, spent 45 mins installing the phone jack and charged me $100 because his rate was $50per hr, with an hr and a half minimum, which is $75 hr. And he also added trip charges, parking and the wire he used to activate my line. I think it was a fair price and I would recommend him to my friends. read more

Harold was prompt, courteous, knowledgeable, understood exactly what we needed to get a work VOIP phone installed. He completed the job quickly, and cleaned up afterward. Everything works perfectly. I would definitely use him again, and recommend him. read more

I found Harold via Yelp in early March 2009. I called him up and he came by within a day or two to look over my job - I wanted to get ethernet wires retrofitted into my SF home. He quoted a very reasonable hourly rate and was very knowledgeable so I hired him. I'm so glad I hired him. This guy does the neatest, fastest work imaginable, with a very low-key relaxed attitude and he was always checking in with me and letting me know exactly what was going on. My house is big with several floors so he was running up and down the stairs and always hustling and working hard and fast, but also carefully. He always did small test holes with the drill bit before doing big holes - to avoid drilling into hidden wires. He ended up giving me a super professional installation with 24-port patch panel, 14 new cable runs, incredibly accurate and careful labelling, and he cleaned up perfectly after himself. I would definitely hire Harold again for any kind of work like this. read more

Harold did a great job of running cat5 from our upstairs bedroom to the downstairs bedroom/main floor. He came over once to assess and tell me about how big the job was, was flexible on options, and also very transparent about any potential issues. In the end, he did a masterful job of concealing the cable so it's hardly visible. We now have solid wifi on our main floor and the few hours of work was very reasonable in terms of cost. Highly recommend Harold and we are going to definitely have him back soon to do more work wiring other parts of the house! read more

Seems honest and diligent. Harold was knowledgeable and patient...I would recommend to friends with DSL telecom issues.

We needed to wire a downstairs office directly to our router. Harold came over the day after we called, mapped out the best and least damaging path for the cable and boom, he was done in an hour. Great service and great work. read more

I hired Harold to do a small wiring job - getting ethernet drops around a small office. He was super detailed and professional. He was friendly and he got the job done on time and his work was super neat and tidy. His hourly rate is super reasonable and he gave me a headsup when he thought he'd need a bit more time than initially estimated and gave excellent reasons for needing more time. When the project was finished I was surprised and delighted to get an invoice with discrete details of exactly all of the work completed. I really appreciate all of those attributes for wiring work. I'd hire him again if I needed help wiring an office -- and you should too! read more

Professional, knowledgeable. Go with Harold for all your telecom needs. He'll get things done right.

Harold did a terrific job wiring my house for a second phone line and also installing CAT5 cables for data, as well as fixing an amateurish CAT5 wiring job that someone else did in part of the house. He's conscientious, reasonably priced, and very detail-oriented. He even labelled everything meticulously. I'd absolutely hire Harold again and recommend him without qualification. He's also an extremely nice guy. read more

Harold was great! I needed a small telephone wiring job done---I used to have 2 phone lines into my house, 1 'regular' and 1 DSL.....then a while back I cancelled the DSL and moved to a cable modem....but then later I needed the 2nd phone line after all....so had it re-connected, but then it wasn't going to all the jacks inside the house the way I wanted. Harold came over and had it all sorted out within an hour. He was really flexible with scheduling, and called to reconfirm the time in advance. Great experience! Highly recommended! read more

We had an outstanding experience with Harold. We asked him to resolve our poor internet connection in the back of our house. He came really soon after I called, sized up the situation, and trouble-shot everything. We were a little surprised he could deal with all our clutter, but he got right down to bringing Ethernet directly from the outside, through the garage, and up into the back office. Now our computer internet is running on a direct line and is blazing fast. Harold is a really nice guy and good person. He knows his stuff and can figure anything out. We highly recommend him. read more

Our ATT landline phone was dead -- no dial tone, though we had working DSL. Could not seem to get a real person at ATT to schedule a repair appt. But our inside wiring was old and we had no way to test the connection into the house, so just to ensure that the problem was in ATT's network, called Harold. He came out a few hours later at an agreed time and carefully and expertly diagnosed the problem as an ATT failure in its system. Three days later, when we finally got an ATT tech out, ATT agreed and we're now going through the process of ATT figuring out which part of its network is at fault. At least we have a working dial tone. I was most impressed with Harold's professionalism and willingness to get to the bottom of our problem and he even fixed a stuck jack. As well, his fee was completely fair. Would eagerly hire again whenever I had another telco or connectivity need. Harold deserves more than 5 stars. read more

Harold Day is reliable, friendly, awesome at what he does, and quick. When I tried installing my DSL, turns out the phone line didn't work when originally wired in the unit. So I needed someone to re-run the phone wire into the apartment unit quick in the same day. Harold said he was available in the afternoon -- sweet. FYI, he's $50/hr with 1.5 hours minimum, so minimum is $75 (not including materials). He came and I was greeted by his friendly demeanor. Because of the simplicity of the job, we asked him to give us a firm price to complete the job, instead of going hourly. He told us $80 including all materials and was really nice about it. Surely enough, he finished within an hour and all the wires were nice and neat, and inside the house they were securely stapled to the edge of the wall. I'd also like to mention that during the consultation we had changed our minds several times on where we wanted the phone line to enter through the house from the outside. He was very accomodating even though a more complicated decision wouldn't affect the firm price he had already set for us. In the end, we chose to have the line come in by the front door instead of through the garage, so it would be side-by-side with the TV/cable jack. Turns out that it was simpler to do it that way anyway-- whew. Otherwise we would have felt really bad. At the end of the visit, I tested the DSL line and it was as good as new, and I was able to install my wireless internet very quickly. Also, the new phone jack was also labeled "DSL" on the outside of the box. We would definitely use Harold again for any telecom issues. I know he also has other specialties...so be sure to ask him. I highly recommend Harold Day! read more

Harold was a great find for us. We are an IT company who needed a subcontractor and he came prepared with knowledge, expertise, and all of the tools imaginable for any voice-and-data job. He sticks it out until the job gets completed even into the late morning hours. We collaborated on a job in SF's Financial District until 3 AM last night. Thank you Harold Day! Day or night he's your guy. No pun intended. read more

I have referred various customers to Harold in the past as I've always liked, and trusted that he was the man for the job.

I called Harold yesterday. Left a message. He called back within a few hours. He had time today for my residential project: Moving a router (with data lines and external internet connection) and installing a bridge line to a modem on another floor. He arrived today on time. We walked through the house. I showed him the locations. He proposed a low cost solution with options. He started and completed the work within a very short time. I am VERY HAPPY with the results. I work from home. Internet connectivity is important. Harold has an old fashioned customer service approach. He was EXTREMELY EASY to work with. And his pricing was VERY REASONABLE. One doesn't find this level of CUSTOMER SERVICE EXCELLENCE every day. I will use him again. And highly recommend him. read more

First time to write to Yelp. I finally got Harold to work inside my house and got everything done in half day. Great work and very pleasant to work with. Would highly recommend the work. read more

I have now used Harold on two projects- two different homes - and both times he arrived as scheduled, assessed the needs I was hoping to accomplish and then present his EXPERT opinion as to how to tackle my wiring issues. He wired my home with CAT6 cabling, installed matching outlets/plates and was able to tell me what wires are Hot or Dead. Cannot recommend him highly enough - improved the IT situation in my home in very short time. Converted old land line phone jacks in to data ports!! Genius. He is a pro and an incredibly friendly individual! About to contact him for another project!!! read more

Harold did a great job! He is very trustworthy and reliable, and takes pride in his work. I would definitely recommend him. We have very tricky wiring and everything worked great. read more

One of those rare gems as it goes with finding someone to help with you home. He was not only an amazing network electrician, he is truly a nice person. I had a home pre-wired with internet networking Cat5e cable and phone lines and Harold basically revealed that the wires were not connected right and then fixed everything! Not only that, 1) he came on a Sun without charging more, 2) after having left the home [to go to have dinner with his family], he called back to fix something that wasn't even his fault!!!! he actually called to come back and fix it after leaving... what an amazing level of service. i would recommend him anyday. He's a great person. read more

We used Harold for our office network and telecom wiring install and he did a fantastic job, working late into the night to finish before our move the next day. I would highly recommend him to anyone looking to work with a professional installer. read more

My elation at buying a new house had a small blip at the state of the coax cable running throughout. Harold helped me wire each room for ethernet and new coax that all terminated in my new server closet. He was endlessly patient with my new homeowner enthusiasm, taking a realistic look at what it would take to run the cable through my existing home without needing to open the walls. He did a very professional job laying the cable and finishing the installation with a professional look. The floor refinishers were to show up the next morning, blocking Harold's access to the rooms; so he stayed until 9:00 at night to make sure the job was completed. He was a pleasure to work with. read more

When I remodeled my house, I had my contractor run ethernet and coax cabling to 5 locations but without termination. Harold terminated those runs and installed a patch panel. He also ran cabling to a new location and terminated that as well. He tested and labelled all the runs. He was prompt and efficient and everything is working great. read more

Harold Day was our savior!! Our office purchased a new phone system to replace our 14 year old one. The installation of the new phones was not as easy as the reviews claimed it would be, so we decided to hire a professional to complete the installation. I called several telecom businesses in the area, but everyone seemed "scared" of the job. BUT NOT HAROLD D! He agreed to come to our office to check out our old telecom set up and to discuss whether he could install the new phones for us or not. Within just a few hours, we had our new phones working! I would definitely recommend his services!! Thanks again Harold!! read more

Harold came to my house to work on Cat5e wiring that was wrong from another installer. He also connected my Sonic DSL (new install) and phone lines from Sonic. He had to work on my patch panel (DSL/Data and Voice breakouts and lots of cabling/wiring). He was VERY thorough and VERY good at explaining what he was doing. What was key to a successful job? He asked the right questions upfront (scoped out the job), came to the job and sat down and talked, then started troubleshooting, found what was the problem and fixed it real quick. He had the right tools, the right technical knowledge, the right problem solving approach, and was excellent at showing me what he was doing/explaining it. He is VERY methodical and was great at labeling all he had done and tips to do any small service work myself. I wish I would have hired Harold in the first place. He was also fast to respond and has been in the business for years (does commercial and High End business jobs as well). I couldn't have asked for better service. All you "do it yourselfers" out there. Stop! Call Harold to work with you as you do it, he'll teach you a thing or two and help you avoid massive issues later with your cat5e/Coax/Voice lines. Really enjoyed the experience. Couldn't have been a nicer/more competent person. read more
