Absolutely outstanding service from C.D. Shanahan's. Armando, Juan, and Elijah were incredible!…read moreArmando and Juan from C.D. Shanahan's HVAC, Plumbing, Electrical & Remodeling LLC came out right before an impending severe snowstorm and worked in sub-15° weather from 8 AM to 8 PM to uninstall our broken Heat Pump and Air Handler and replace them with a brand new Heat Pump and Air Handler. Simply put: these guys were the best. Incredibly professional, hardworking, and dedicated from start to finish. They didn't rush a single step. They also helped install a new thermostat, made sure everything was running smoothly, and ran all the necessary tests to ensure the system was operating perfectly before they left. Huge shoutout to Elijah as well!. He took the time to explain everything in detail about the humidifier, thermostat, and Air Handler, and gave us genuinely valuable maintenance tips that made us feel confident moving forward. C.D. Shanahan is probably the best HVAC company you've never heard of. If you want a team that shows up, works hard, communicates clearly, and takes real pride in doing the job right. Highly recommend.

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.

I reached out via Yelp to five different plumbing companies in the NoVa area for quotes and an idea of when they could help me out. Arlington Plumbing Heating and Cooling replied to my inquiry within minutes. I received quotes from three companies and Arlington Plumbing's quote was competitive. I was sold by Arlington Plumbing's promptness to my request and their professionalism on the phone. It was 9am, and I was told I would have hot water by the end of the day. Arlington Plumbing Heating and Cooling delivered. I was given an estimate of the time they could do the work and over the course of the day I was contacted a number of times via phone that they were on track. Arlington Plumbing arrived at the agreed upon time, did the work with a professional manner, they did a great job of cleaning up, and I had hot water before my spouse arrived home from work. My spouse thought I was a hero, but it was really Arlington Plumbing Heating and Cooling that was the hero. Thank you. I will definitely use this company again when I have my next plumbing issue. I will absolutely provide their contact information to my friends and neighbors when they have an issue.

The true quality of a company is revealed when something goes wrong. And in this case it did and…read morethe results were bad. I hired the company to repair my washer. Diagnosis visit was great. Not so good after that. First repair appointment was cancelled during my scheduled appointment window because the part wasn't in yet. Second repair appointment, Mohamed showed up for the repair only to realize he had picked up the wrong part. The worst part was how he handled it. He said he had to drive back to Alexandria to get the right part. I had another contractor appointment at another property and told him my schedule was very challenging. He immediately became angry and literally started yelling at me. Said he was very busy too and this was messing up his whole schedule, exclaiming that it wasn't his fault. I was hoping to discuss our schedules to figure something out but he was losing it. I was trying to figure out what to do and he was yelling, "decide! decide!". Overwhelmed, I decided I would tell him go get it and come back and I'd try to figure out a solution in the meantime. After he left, I messaged the company and asked that they send another tech. They didn't have another tech. They refused to answer the phone and were not apologetic. Fortunately I was able to get my husband to come home from work and be there. At this point I was very upset and didn't ever want to see that man again. When Mohamed returned he fixed the dryer and apologized to my husband, but not to me, even though he was still texting me. Said he was really stressed. A little over a month later the part failed. It made me sick that we had to go back to the same company. They again said they didn't have another tech so again I had my husband be there for the appointment. I realized that likely there is only one Mohamed and the owner and tech are the same person. In spite of everything that had happened - the canceled appointment during the appointment time, showing up with the wrong part and yelling at me for it - he charged us $79 trip charge to replace the failed part. Said his labor warranty was 30 days. Here he had an opportunity to do something to compensate for his previous behavior and last minute cancellations, but he chose not to. I will never use this company again and do not recommend at all. So many good reviews but when things go wrong, beware.

Additionally their billing is unreliable, causing more hassle with sorting through old invoices to see what has been paid and what has not. I will not be using them again. Note: Every technician and installer that came out for this project was always professional and knowledgeable. The issues I had were with the managers, the estimators/contract reps, and the back office.
