    Over soldered pipe leaking, refused to fix
    Rachael P.

    Highly recommend you keep looking for a plumbing professional. If a mistake is made good luck getting them to repair the issue without major headaches. Worst experience, terrible professionalism.

    Michael S.

    After a power surge from the big storm, the electricity did not come back. I called 4 Service Pros to restore power. All the electrician did was to switch the basic on/off function, which switches from left (the off) to right (the on). But he still charged me over $256 for labor and $150 for emergency fee for only a 30-minute work. That's over $400! It's the biggest rip-off I've ever experienced.

    New shower/bath fixtures.

    All-around great company and excellent customer service. Technicians Zachary and Henrri identified cause of water leak from upstairs bathroom to downstairs laundry room. The leak damaged the drywall ceiling which also exposed other leaks. A technician from another company conducted the initial "repair" but did not completely resolve the water leak. Zachary and Henrri replaced the waste and overflow pipes. In addition, per request, they replaced the shower control and diverter spout and did a great job in sealing the fixtures as some of the water was leaking around the old spout and shower control handle. Thanks to Zachary and Henrri for their outstanding work. Also, thanks to the great office crew for scheduling my appointment! Definitely, a returning customer!

    New faucet on left, old one on right.

    I needed a plumber to replace my old faucets and replace my leaking supply lines. I checked Lowes for a quote and it was less expensive, but I ultimately went with 4 Service Pros because it was so much easier to reach them and schedule. I also liked that they come with a fully stocked plumber's van, so I didn't need to worry about having the right supply lines for the faucets I purchased.

    Digging out the old line and new line trench

    I had to have my nearly 60 year old cast iron sewer lines replaced at my house, inside and out. I can't speak highly enough about my experience with Matthew Loring and Stephen Savoy. First class service from the first day they showed up to do the initial inspection and quote, to job completion. They came prepared, immediately identified the issue and started formulating a plan of action on the spot. They even started locating the lines under the concrete in the basement to better describe how and where the work would be done. Due to the complexity of the work and the location of other pieces of equipment, I had planned on being without hot water and/or heat (boiler system) for a time as they removed the old lines but I was wrong. They are skilled enough that they didn't need to take them offline and got the job done in the original time frame proposed. A+ They are extremely professional, showed up on time and did not try to upsell me on anything. They truly understand what it means to provide customer service and exemplify it to the fullest extent. I would hire them again in a heartbeat and continue brag about them to anyone who will listen.

    We service all of Northern Virginia and parts of DC and Maryland.

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.

We pushed off the replacement thinking our unit would survive one more winter, but of course of furnace went out unexpectedly in the middle of the night during one of the coldest stints of the season. Called Residential Express the following morning, they pulled up my quote from 4 months prior, verified the price hadn't changed and were able to schedule me for a full HVAC replacement the next day. Freddie and Flavian arrived on time and were very professional moving through our house and working in our backyard and utility closet. They explained any changes they needed to make, went over the new setup and recommended service intervals, and hauled all of the old equipment away, leaving our house looking better than when they arrived. Very happy with our experience with Residential Express and wouldn't hesitate to use them again.

Literally wearing a sweater and two sweater wraps. New HVAC filter, reset breaker. Thermostat batteries are fine. Still not kicking on. Sent Yelp message to RES because they have always been quick to respond. And they did this time as well and the woman who gave me a call was nice and tried to help. Pretty disappointed that they can't quickly swing by today. From what I've read, it's likely a dirty flame sensor or the ignitor switch (neither of which is a long job - I just don't have the tools). HVAC less than 5 years old, so parts are under warranty with RES; however, I had to call someone else. Bottom line: Someone else is coming today, but I could end up paying for parts. Kind of feels like my current needs weren't lucrative enough for RES to make a concerted effort to swing by.

They are exactly what was sent, with my email address, phone number, and home address redacted. The first issue with my new HVAC system required 4-5 service visits over multiple days before it was resolved. After the issue was resolved, I repeatedly asked about FH Furr's advertised $500 No Frustration Guarantee. I never received a callback or any type of explanation--they simply ignored it. The second incident was even more frustrating. After my service request had already been pending for over 24 hours, my appointment was pushed back another five days during a heat wave because a specific technician was apparently needed. I called back to ask if another technician could be sent sooner because waiting five more days was not acceptable with 95+ degree temperatures and the upstairs reaching around 80 degrees with two young kids. At the same time, I asked that a manager contact me to discuss my concerns with how the situation had been handled up to that point. I was repeatedly told someone would call me back (twice by phone and once through a technician), but nobody ever did. I followed up with two detailed emails to document the issue and give FH Furr the opportunity to handle it, including asking again about the $500 No Frustration Guarantee. Those have also gone unanswered. If you end up with an issue requiring anything beyond dispatching a technician, don't expect management to follow through. At this point, their $500 No Frustration Guarantee feels more like a sales promise they have no intention of honoring. Every technician who came to my home was professional and did everything they could to help. They are not the reason for this review. This review is entirely about FH Furr's management and customer service. I will only be contacting them for future HVAC repairs while the warranty on their installation remains active--and only because I have little choice.
