I am very satisfied with the work and service provided by Kamel Sebaoui today. First of all Kamel was on time for the appointment, and had a very pleasant personality. Initially, he asked realistic questions to help gear him in the direction of the plumbing issue in my home. Kamel was very attentive and offered a couple of suggestions to resolve my issue. After giving me a choice with deciding which direction to go to resolve the plumbing issues, he then offered his recommendation.. I am grateful to have followed his recommendation, because it was definitely the best solution to the plumbing problem. I was quite intrigued with Kamel's completion of the task in such a timely manner. Afterwards, Kamel performed a few test to ensure the problem was resolved. I'm very appreciative how he did an amazing job with resolving my plumbing issue, and also cleaning up afterwards. I highly recommend Kamel Sebaoui for any plumbing matters. Thanks Kamel for relieving my family of the unexpected plumbing issues. Services Plumbing leak detection, Plumbing pipe repair, Plumbing leak repair read more

Flood came out to give my mother an estimate on a plumbing job in her basement. Quoted a number twice as high as the other two plumbers we had out. Additionally, they brought in somebody to look at other issues that no one else saw. I called on my mother's behalf to give Flood a chance to explain their proposals. I explained my hope to the individual who answered the phone who said the plumber would call me back that day. I never received a call. I called a few days later and spoke with their Customer Service lead. She promised me a call before the end of that business day. That was a week ago. I generally don't post reviews on Yelp, but was so bothered by their treatment of an 83-year-old woman and me that I felt compelled. read more

Excellent service. David, the technician, was on time, friendly, efficient, & competent. He explained everything to me before doing any work. When my heater wasn't working right, he identified a new issue & fixed it alongside a scheduled repair. I've always found JC Flood to come out quickly when needed & to stand behind their work. They are pricier than other places, but I think you get what you pay for! read more

1/5 Stars -- Disappointed and exploited loyal customers My 84-year-old mother, who has been a loyal customer of J C Flood for years, recently had them come to her house for service. They quoted her one price upfront and then charged her significantly more on the final bill--which they didn't even show her. Because she is not very familiar with computer systems, they completely took advantage of her vulnerability. Taking advantage of an elderly customer who trusted them for years is completely unacceptable behavior. When I called to address this, I spoke with Johny Thomas, who informed me that he is the owner of the company. When confronted about the unfair pricing, he simply told me, "The price is what it is," a dismissive statement I had to repeat back to him. As the owner, his utter lack of empathy and complete disregard for my mother's situation was deeply disappointing. His attitude was completely unprofessional, showing a total lack of customer service skills. If they are willing to treat a loyal, elderly customer this way, they will do it to anyone. Stay away from this company. read more

Once again, John Flood came to the rescue. Hot water heater was not producing hot water called them on Sunday and Michael McIntyre showed up on Monday It needed a new part and Michael took care of it took care of it. True professional, thank you, John C Flood. read more

Speedy response, professional plumber in Harry, but the charge was much greater than what was expected.

We have someone from John C. Flood at the house on a regular basis to handle any heating, plumbing, electrical or air conditioning issues that pop up and they're ALWAYS ready with the best solution, best price and best trained technicians! Our latest experience was with Matt Gagnon to get an estimate for a whole house humidifier system installed. He was very knowledgeable and provided the right solution for our circumstances! He didn't try to over-sell or up-sell, he gave us the right advice and now we're going to have them come out and do the work in a few days (they have to order the unit). Just another in a very long string of positive experiences we've had with John C. Flood! Oh and BTW, it's not lost on me that the company supports many community organizations throughout the year, including one of my favorites, Mission 22. www.mission22.org. You would be well served to hire John C. Flood! read more

Sewer backup and Carlos from John C Flood came first thing in the morning to diagnose the issue. He worked for several hours finally finding the problem great job Carlos. read more

I used John C. Flood at two of my homes. They are very courteous and thorough. They provide you with pictures and a summary of what they did, as well as estimates of what they recommend. They are definitely not the cheapest game in town but are worth the extra cost. read more

Yesterday I had my best service experience yet with John C Flood. The new HVAC tech was David Cannon and he was outstanding. The techs are always excellent with JCF but David stands out above the rest. Quick, efficient and a good sense of humor. He also goes the extra mile as he lays out your options. Can't say enough good things about him in Particular and JCF in general. read more

While Andy C had some bad news to deliver [the broken circuit breaker is no longer available, so the entire electrical panel had to be replaced, at 10x the original estimate for repair] he did a great job. After examining all options for a less expensive repair, he indicated that the only option was total replacement. He did the work quickly and professionally and was very personable. read more

I called Flood about a pilot light issue on my hot water heater. The receptionist told me they would send a technician and that the usual $100 service fee for coming out would be reduced to $59 for first-time customers. After pushing the knob and lighting the pilot light he charged me $251. He said that was the flat rate, even though no parts had to be replaced or cleaned. He also gave me an estimate on a new heater, should this one fail. This is a classic bait-and-switch when they offer a $59 service call and then charge the "customary" $251 fee. Flood should have been more transparent up front, especially when I specifically told the receptionist the nature of the problem. Moreover, the salesman, trying to sell me a new unit, said he could take $251 off their estimate if I bought it TODAY! - a clear example of "urgency marketing" which no reputable company should be engaging in. He also gave me this song and dance about how my house is the largest investment I have, meaning (I suppose) that I shouldn't be that concerned about their price gouging. Needless to say, I am very disappointed in this company and will never be using their services again. read more

My late husband and I worked with Climate Heating and Cooling for 44 years. They were always there for us and, if needed, went beyond the line of duty to help. Unfortunately, John C. Flood bought them out but failed to acquire Climate's values, especially customer relations and honesty. When I phoned, a few months ago, to make an appointment, they were very fast to offer me "a membership" that would give me so many benefits. And they promised the best service. Since then, I had an electrician come to check the attic fan. He arrived two hours after the scheduled window and promptly turned off all the switches in the attic including the power switch to my Verizon Fios system which caused a mess that took Verizon two weeks to completely fix. Then a technician came to check on the air conditioning units. He was also two hours late and I had to cancel him because it was too hot to go up to the attic. So, he had to come the next day. An excellent technician, Francisco Toledo. Did a good job on checking everything. However, nobody from the company alerted me to have new filters (Climate always brought filters, charged me something for them, but never for installing them, which is a nothing job, except that at my age, I no longer climb up to the attic). But, now I had to order the filters, they sent Francisco back to install them and charged me $165 for something that should have been part of the regular maintenance. Francisco also gave me an entire estimate of repairs, improvements and upgrades that he highly recommend I do, to the tune of thousands of dollars. Following this unpleasant experience of them charging me for installing the filters which should have been part of the annual maintenance, I doubt, very much, that I shall do any further business with John C. Flood once my current maintenance agreement expires. This is not the way to treat customers. read more

Had installation of hot water heater service performed February 24, 2026. The technician showed up half an hour after the scheduled time of 8am. Once the technician showed and explained the process things seemed to be ok. However, the technician by the name of Carlos declined to inform us that there were any issues with spacing even after taking the initial measurements and quoting an estimate during our consultation which occurred one month prior. In fact, he made it a point to inform us that he has dealt with tighter spaces and assured us that he was able to perform the task failing to mention any possibility of alterations. He attempted to willfully conceal what he did by hiding the materials he removed to another corner of my basement where at first glance it wasn't obviously visible without having to look for it. I never gave consent to this compromise. Unfortunately, once complete, I discovered the technician removed a couple 2x4 vertical studs damaging the drywall which exposed the nails and split the wood in the process. This in turn raises a safety concern along with the mess and work supplies left by the technician. I immediately contacted JC Flood (Alexandria location) the same day and was connected with their plumbing general manager Pat. I informed him of the structural damages to my property. He informed me he would speak to the technician Carlos about the situation to review the photos and get back with me to make things right. However, since then it's been a complete nightmare. It's been almost two months; the manager never got back to me about a resolution and the company has been avoiding my calls after making numerous attempts repeatedly and consistently getting brushed off. In fact, I have called so many times, the customer service reps became familiar with me This has been such an annoying yet frustrating experience and to think JC Flood is supposed to be a reputable company. JC FLOOD HAS BEEN MORE CONSISTENT WITH BRUSHING ME OFF THAN CONTACTING ME WITH A RESOLUTION! I AM BEYOND BELIEF THAT THEY THINK IT'S OK TO LEAVE MY HOME THIS WAY! I WOULD NEVER RECOMMEND THEM TO ANYONE!!!! read more

See all

I had used this company in the past unaware of just how expensive they were. I called them out for a routine HVAC servicing, and before the tech even opened a panel, was positioning for a massive upsell. I told him that I am not interested in buying an entire new system and I just need the basic servicing which seemed to annoy him. He did an assessment and came back with a report that basically made it look like my system was about to crash at any moment. For a basic cleaning he quoted me at $5,700 plus, but strongly urged me to go out and buy one of their $17,000 high efficiency systems. I decided to go with a local contractor, who came out within 2 hours and found a few minor tweaks that needed to be done, cleaned both my units, insulated the wires to code, and praised the condition and make / model of my units. All in all, it cost me $850 total...a far cry from $5,700. The only reason they get 2 stars is because they are prompt and communicative (albeit about trying to sell you unneeded services and products), but I will never in a million years use this company again. read more

I have used John C. Flood often for both my primary residence and rentals. While they do good work and show up on time, their prices have risen to an absurd point - last week, I was charged $400 for a tech to spend a few minutes cutting a 12" hole in drywall on top of the cost to repair the pipe itself. This followed a visit where we needed a $15 flapper valve replaced, and the tech told us his lowest-touch repair option was to rebuild the entire toilet at a price of roughly $600 (options went up from there to a toilet replacement at $1,500.) I won't use them again. read more

The person was polite and professional in his presentation. He looked closely at my units, the ones outside and in the attic to make sure that he had the correct information for replacement units. read more

We had a technician evaluate our a/c unit. We were told that the compressor had failed and we needed a new one. We ultimately signed a contract for $11k, after lots of emails and calls "encouraging" us to commit. Turns out a second company - we had forgotten we had called multiple because service was slow - identified a blown fuse. Cost us $28 plus the cost of the service call. Our a/c works and we saved $10,972. read more

Fernando the technician, who initially arrived to diagnose my problem came quickly and assessed my problem with clear options on how to proceed. He was professional, and well spoken about his product and procedure alternatives. In other words he really "knew his stuff". It is also important for me to feel safe and secure with who enters my home if I have not used them before and Fernando passed that test almost immediately! Flood is also willing to negotiate the price somewhat to meet the needs of the homeowner, so I appreciate the flexibility. With their membership plan, they can offer certain free options for service, repair etc. I can understand why they have served the DC area for 120 years. read more

Sylvester McDowney at JCFlood did an emergency fix on a leaky toilet last summer/early fall and and also upgraded some valves. The service was OUTSTANDING!! Sylvester was on time, courteous and professional. I felt really at ease when the job was done. I will be using JC Flood and requesting Mr. McDowney later in 2026. read more

The service representative was excellent at performing the requested repair of a leaking outdoor faucet. However, the cost was RIDICULOUS. The estimate was $1021, but he did the repair in 45 minutes. I didn't do my due diligence by getting a competing estimate. After talking with another plumber after the repair had been completed, I was told that it should have cost no more than $500. I'll never use John Flood Plumbing again. The experience reconfirmed my failure to get competing estimates. read more

John C Flood, an HVAC company, responded when our boiler suddenly failed leaving us with no heat or hot water. I gave the JC Flood techs 5 star reviews because of their troubleshooting skills and they showed up on time. Their proposed repair included a $2,000 surcharge to immediately get the $500 part they said was "was generally not readily available for weeks" or $18,800 to completely replace our fairly modern boiler. I researched the failed part availability and found where they could get it the next day from a quality HVAC part supplier. They apparently were interested in repairing only if they could significantly increase the cost to us. They then ghosted us by not returning calls. I have lowered my review to 1 star because the company was interested in repair only if they could tack on a $2,000 surcharge based on the deception that the part was not readily available or sell me an entirely new system for almost $19K. read more

Joshua Grant was courteous and extremely knowledgeable. He provided diagnostic and various recommendations to solve our water heater issue. Cost was well defined and explained in the appointment and well worth the visit expense. Certainly will use John C Flood in the future. Also appreciated Joshua's depth of knowledge in the current trends in the water heating industry - amazing! read more

Luke T came out to do an ordinary checkup on our HVAC system, which had been installed by another company. He was meticulous, knowledgeable, and friendly. Not only did he find several rookie mistakes by the prior company (they literally didn't connect the wire to activate the second stage of our 2-stage heat pump!), he took the time to explain things about the system and give us info on how best to maintain it. The checkup took longer than you'd expect, but that's because there were genuine problems to fix, and he fixed them. I couldn't be happier. read more

I was a happy customer of Air One Tech, but since they were acquired by John C. Flood my experience has gone downhill. The technician who came out to inspect my system was polite and professional, but the estimates were shocking. I was quoted $605 for a refrigerant dye test/top-off and $337 for a simple condensate line cleaning -- almost $1,000 total for what should be minor service. A second "system restoration" proposal came in at $1,726 for pan tablets ($190), blower wheel cleaning ($768), and condenser cleaning ($768). These are mostly maintenance tasks, yet priced like major repairs. I didn't feel pressured by the technician's language, but the numbers speak for themselves -- this is a commission-driven pricing model that inflates costs far beyond what I paid with Air One Tech or what independents charge in Northern Virginia. While the techs may be courteous, the business model isn't customer-first. Based on these experiences, I won't be doing business with John C. Flood going forward and would strongly recommend anyone considering them to get a second opinion before approving work. read more

I had a great experience with Nathan Lee when he came to service our heater unit. He was thorough, knowledgeable, and extremely professional throughout the entire visit. Nathan took the time to carefully inspect the system and clearly explained what he was doing each step of the way. He made sure I understood the work being performed and patiently answered all of my questions. It's clear that he takes pride in his work and truly cares about doing the job right. I really appreciate his attention to detail and excellent customer service. Highly recommend! read more

Mr Francisco Toledo, did a excellent job He was polite,respectful and very detailed oriented .He didn't not rush in and out ,he was very efficient. Thank you for the service read more

Sean Hoffman was excellent. He is professional, extremely knowledgeable and honest. Our Heater quit working and after a diagnostic procedure Sean found it was a little sediment that came in from the high winds. He blew it out and reset it after making sure 3 times the heater came back on. I was absolutely over the moon happy. We always used Climate air & heating for 30 years with Cory. John C Flood bought them out as they are just as good with my Lennox Air Conditioning and Furnace for heat. read more

Will never use or recommend John C. Flood whose business strategy is fleecing customers. First thing to know is they send a link from an outfit that filters bad reviews once you pay, so only the good ones are actually posted. IGNORE the amount of positive ratings, the bad ones get lost. Second thing to know is this is one of the many "local" companies that probably formerly provided great service at a reasonable cost unfortunately bought by a private equity company to squeeze the last drop of blood out of the turnip to benefit themselves while delivering no value to customers. I had an electrical issue for a tenant occupied property. Tenants are good and try to figure easy issues out, but could not. I suspected it was an easy issue and scheduled a 12-5 window with John C. Flood to check it out. They said a $99 service charge for a visit. Problem #1 - I get a text and phone call before 8 a.m. they're on the way. Keep in mind this needed to be scheduled with tenants and it was scheduled for Noon to 5pm. Fortunately, the tenants are available and can accommodate. Problem #2 - that $99 service charge? Oh that's if there's an actual repair! They actually charge $249/ hr and one hour minimum. As suspected, the issue was an easy breaker that was a little fussy. So $250 to reset a breaker that probably took 10 minutes. NEVER AGAIN! Do a search for any company providing home services like this that seems local to see if they were acquired by some useless firm to screw you over and profit themselves. read more

Totally recommend this company!for hvac, plumbing or electric! Super happy with their fair practices on price and work. We've used these guys since 2017 at both our houses in the Md/ DC area. read more

I cancelled my account with John C Flood in June 2025. I just realized they have continued to charge my credit card monthly despite 2 notifications in writing in June. I've had to open a dispute with my credit card company to get this resolved. I was not happy with the service anymore as the maintenance calls turned more into sales calls for proposed unnecessary work at excessive cost. read more

Had the pleasant experience as a John C. Flood customer using their electrician services to have an outside flood light replaced and installed. Their technician, Carl F., was personable, highly skilled, and TRANSPARENT with all parts of the job performed. Will use them (and request Carl) for getting an electrical outlet placed in one of our bathrooms. read more

My partner and I had an extremely disappointing experience with one of their technicians, Nassim Sebaoui. We were looking to fix a leak in an old water line that was getting disconnected and the technician told us it would be an easy fix and then gave us a quote for $573. That seemed excessive. When we asked for a breakdown of why it would cost so much, he was extremely flippant saying "it wasn't up to him what the price was" and followed up with "When was the last time you hired a plumber? We're expensive." The fact the technician either couldn't or wouldn't give a breakdown to explain the cost was concerning and made us feel like he and/or John C. Flood was trying to take advantage of us, so we refused the service. Based on this interaction we will not consider John C. Flood for future services. read more

The technician came in on time. It was a difficult problem but he was able to find out the issue and fixed it. The weather was hot and humid when he was conducting the work. A job well done! read more

I call John C. Flood stated that I have a smell coming from the kitchen sink. Javier came out and run a water test found out no clog. He ask me to turn my dishwasher on and the odor at the kitchen sink is likely coming from any standing water in appliance. Also Javier perform a water heater flush to remove sediment and mineral buildup from the bottom of the tank. read more

Javier Ruiz-Gonzalez was very courteous and professional. He diagnosed the plumbing issues with the four toilets in my house and provided a range of recommendations to resolve the water leak issues, and explained the costs and benefits of each. I've used John C Flood for 20+ years and will continue to do so. Highly recommended. read more

Our Eccobee thermostat had been constantly rebooting all winter, we finally decided to have it checked out. The appointment was scheduled the same day that I called. Matt was very professional & thorough. He took the time to insure we understood the problem and the solution. We have a contract with JCF so the service call did not cost anything. Matt is an awesome guy. read more

Our upstairs a/c system stopped working and a technician from John C Flood made assessed issues, made adjustment and it worked. However, we came back from a 3 day trip and house 83 degrees. Today, Arlene Rodriguez came and having listened to first set of problems and fixes, did her own review, tested a few things, determined that the issue was a worn out piece, replaced it and all well!! She was very friendly, efficient, good at explaining and listening and obviously effective!! Great service. read more

The technicians misdiagnosed an issue with my HVAC/thermostat, and I ended up paying for a new thermostat and installation that I did not need. I had three different technicians sent out on three separate visits, and none of them caught the actual issue. The senior tech who got sent on a fourth visit and finally figured out what it was was the one who originally misdiagnosed the problem. The tech attempted to charge me to fix the issue after misdiagnosing the problem in the first place. I called customer service, and they agreed to compensate me and send a different technician to assess and address the issue. The team sent out included the senior tech that I was explicitly told was not going to be there, and the technicians sent attempted to charge me for the visit that I was being comped for. read more

I feel a little bad even leaving a review since I didn't really get any service but that is part of the story...read on. I found this company because our sump pump did not trigger during a rainstorm but once we messed with it it turned on. I googled how long they last and found their website saying 5-7 years and suggesting regularly (yearly) checkup. I figured I'd give them a shot since I appreciated their advice and even found a coupon on their website for a free checkup. Scheduling was normal, call in, schedule a time, morning/afternoon, couple days away. At the end, the person fielding my call asked if this was a good number to text me on. I said I didn't want texted and she said she'd make a note and stick to email. Right after the call I got a text and this probably should have been a flag. Jose arrived and did the inspection. I explained what had happened and he looked and said he didn't see anything wrong and borrowed a bucket (why do people not have tools and expect you do?) and filled the recess with water and it worked as expected. He suggested why it might have happened and not to be worried but to get a backup. I actually had a backup but hadn't set it up and he said his company would do it but not be able to warrentee. My normal plumber won't do it, so that was interesting to know. He said usually they install sump and backup together and cited off memory ~3k which was more than 4x what I had paid for the last sump. He also said that the pipes were .25" vs .5" which was weird. While there he noticed some old valves and pipes and recommended they be replaced. I also asked him about a blocked drain outside and he said they could do it and gave me estimates for the valves and the blockage. He also mentioned that normally inspections were paid but you would get the money back if you bought into their service. He also casually (no/low pressure) relayed they had a basically warentee service where they'd make 2 plumbing and 2 HVAC inspections per year no change at the cost of $200 non-renewable. Good to know but I didn't do it. So he left and I felt like the exchange went well, I felt better about the sump and got some free advice and thoughts about the company. The next day I got mail and text (despite my ask not to be texted) from a sales guy offering follow up. I mailed him back and said that I had some other stuff to do first and asked how long the estimates were good for and also that I needed to remove my text from their call center apparently. He said no problem and 30 days and to let him know. A couple days later, more emails and texts. This time I reply more strongly saying we talked already and not to contact me. Then more emails and texts. I noticed the emails have an unsubscribe feature so now I figure I'm on some auto mailer. I unsubscribe and block him. A couple days later my sump pump does the same non-trigger thing. So despite having it looked at, it was having issue. So...basically I got nothing from this company. Because of this, I just went with my normal plumber and replaced the sump pump via them. For under $800 (no backup). Ironically that plumber replaced some of the .25" pipes with .5" without asking so I guess they also thought it was weird :P Anyway TLDR I appreciate the free advice both website and from the service tech but their prices seem higher than I've experienced and their sales people are super aggro. With this non-experience I'd probably rate 2.5* mostly because it was free (but rounding down because of Yelp and imagining it wasn't). read more
