    I hired Reddick & Sons Plumbing to install a new heat pump system. The work was done on time and…read morewithin budget and I am very happy with the results. I had several additional requests which they accommodated such as adding an extra drain line and additional return vent and all the work was done as requested. Since completion of the job, they have come back on routine maintenance visits to keep the system up and running and the cost of which was included with the original work. I therefore. have been very pleased with after-installation service. Separately, I used them for plumbing, specifically replacing a sink faucet, repairing a garbage disposal, and repairing a leaky shower fixture. I was very pleased with this service as well. Especially the garbage disposal because all it needed was a minor turn of a crank to loosen it up instead of a full replacement, which saved me a significant amount of money. Obviously, overall, I'm very happy with their services. I will be using them again and highly recommend.

    I found them through Yelp project among 10 others and after talking to reps I decided to stick with…read moreReddick,because of clear explanations of pricing and upfront fees. It's unbelievable but some companies required upfront deposit even before assessment of the issue. Our technician,Brian,was on time,called prior,came with shoe covers,quickly identified problems with toilet,gave us estimates and couple options to think about. I called next morning and next business day he returned and completed repair. Again on time,very professional and leave no dirt or waste after job. Prices are horribly high now everywhere,but plumbing can't be avoided,so their price point is adequate to area,but service is superb. Can't deduct star for high prices,because they are using gas and supplies which are horrible now.

They went above and beyond to get our gas lines fixed and ensure our water and gas lines were properly bonded after lightning caused extensive damage to our home and gas lines. A special shoutout to James Jordan for going out of his way to make sure everything was clearly communicated and completed in a timely manner. His attention to detail and commitment to keeping us informed throughout the entire process and getting the project completed even when dealing with multiple issues were greatly appreciated. He made sure we had the key people from his team assigned to this project. We also want to give a huge thank you to Mike Kriesten and John Lambert. They worked an incredibly long day and well into the night, then came back first thing the next morning to finish the installation of our new gas lines. Their hard work, professionalism, and dedication to getting the job done meant more to our family than we can express. When you're dealing with something as important as your home's gas and water systems, having people who genuinely care about doing the job right makes all the difference. My family and I can't thank James, Mike, John, and the entire Marines Service Co. team enough. Exceptional service, communication, and dedication from start to finish. We are incredibly grateful and would highly recommend Marines Service Co.!

I had a plumbing issue that was starting to stress me out, and from the first phone call, I felt like I was dealing with professionals who genuinely cared about helping -- not just booking another job. They responded quickly and showed up right on time, which already put them ahead of a lot of contractors I've dealt with before. The technician was respectful, knowledgeable, and took the time to actually explain what was going on instead of just throwing out technical terms. I really appreciated that. It made me feel informed and confident about the repair. What stood out most to me was the honesty. There was no pressure to upsell anything unnecessary. They focused on fixing the actual problem and making sure it wouldn't turn into something bigger down the road. The pricing was clear and fair, and there were no surprise charges at the end. The work itself was done efficiently and with obvious attention to detail. Everything was cleaned up afterward, and you honestly wouldn't even know work had been done -- except that the issue was completely resolved. It's hard to find reliable service companies these days, but Crown Plumber exceeded my expectations. If you're in Ashburn and need plumbing work done right the first time, I wouldn't hesitate to call them again. Definitely five-star service in my book.

    We have had two experiences with Crown Plumber and the latest was so exceptional I wanted to…read moredocument it here. We had a leak in our basement and believed it to be caused by a toilet leaking. A plumber came (not Crown) and fixed the toilet but the drip persisted. When I tried to call this unnamed plumber back, he said he was out of town for a week. Ugh! Crown to the rescue! I called crown and they sent Elvis over to explore our problem. Elvis quickly determined that the toilet was not our problem and set about exploring other options. After some good detective work, he discovered a very slow leak inside one of our walls. He expeditiously fixed it and explained the cause. This guy knows his business! We also appreciated his being upfront about the cost of his visit had was careful to document the itemized bill. He even carried a book of possible repairs and their cost for transparency. It is hard to find a good plumber but I have high praise for Crown and recommend them without hesitation.

He explained everything, fixed the problem, and made some sound recommendations. Thank you AllTech and thank you Kai.

He identified some issues, but never told me what the required repairs would be. Then he told me that the repairs would cost us 75% of the cost of a new unit. He said that the AC unit needed to be replaced and possibly the air handler and even the water heater. This last recommendation made me skeptical. I asked for a quote on the repairs and separately on the cost of replacement. He said that replacement would require another 90 minute appointment; which I was not ready to commit too. I was expecting a quote and detailed listing of the repairs. We never received this quote. Based on the technician's description of the issues, my husband and I were able consider some potential repairs on our own. We made the repairs on our own (coil cleaning, capacitor replacement) and everything seems to be functioning well so far. My concern was that AllTech immediately jumps to a recommendation of replacement if a unit is older than 10 years. We never received a quote on the cost of repair. The repairs my husband and I made required roughly $30 worth of parts. I wish that AllTech would have provided the quote for repairs and not immediately jumped to the cost of an entirely new AC system. Also suggesting to replace the air handler and water heater was excessive.

John came out and was very straight forward and up front with everything he did. He explained the issue to me, how he would fix it, and even provided some recommendations I may want to do in the future. My second time I used Bluestar was on a Sunday and they are closed on Sunday's. I did not realize this at first and left them a voicemail in the morning. Realizing they were closed I called another company who would have charged me more than Bluestar to come out later that afternoon to look at the problem which was that my Nest Thermostat was giving an E73 error code meaning it was not getting power. To my surprise I received a call from John at Bluestar that afternoon prior to the other HVAC company coming out. I discussed my thermostat issue not getting power with John and he suggested several troubleshooting fixes I could try over the phone. After eliminating several causes of what the problem may be John suggested holding down the front panel cover switch to the unit to see if a power light was coming on. In doing this I noticed sometimes the light would come on and sometimes it would not. There seemed to be a loose connection in the a wire that was causing the switch not to supply power. After playing with the switch for a few minutes I got the power to stay on and the problem was fixed. John solved my problem and saved me a good deal of money as I canceled my appointment with the other HVAC company. John took over 20 minutes talking to me on the phone going above an beyond to help me solve my AC issue on the day the company is closed. I would highly recommend BluStar to anyone and will use them for all my future HVAC needs.
