I had a gas leak. Len the Plumber sent their technician, Brandon Hemp. He was awesome. He worked all day and fixed the problem. Really nice guy, knowledgeable and friendly. Would use them again. read more

Charged us $700 to replace a $26 capacitor on our AC unit. Made much worse with very deceptive scare tactics to repeatedly push a $1900 compressor swap. Tech showed me some amp readings on his multimeter saying it was a warning sign that the compressor was failing. After research I found that the amp reading he was showing was the exact operating amp rating that was very clearly marked on the side of the outdoor unit. I will never use this BS company again. Use ChatGPT to run whatever they're telling you through it as a sniff test. They will try to scare you into replacing parts. read more

$744 to fix what was a worn faucet cartridge. Get a second quote before you let this company touch anything. The technician presented exactly one solution: rip out the whole faucet and replace it, plus the supply lines. A cheaper cartridge repair was never offered, never mentioned, never priced. One option, take it or leave it. The bill came to $744 after a "discount." For reference, a mid-range faucet supplied and installed runs about $250-$600 all-in, and a cartridge swap is a fraction of that. I paid top-of-market for a job that went well beyond what my faucet needed -- to fix a problem a much smaller repair would have solved. To be fair: the work was completed and the technician was polite. That's not the issue. The issue is being funneled straight to the most expensive option with no honest discussion of the alternative. That's not how a company earns trust. If you call them, insist on a written diagnosis and ask point-blank whether a smaller repair will fix it -- before you authorize anything. Don't assume the first quote is the only option, because in my experience they won't tell you it isn't. read more

Formal Complaint and Refund Request - Job #1402068744 I am filing a formal complaint regarding HVAC service performed by Len the Plumber Heating & Air on August 7, 2026, and requesting a full refund of my diagnostic/service fee. I called because my AC was not working and water was on the floor around the HVAC unit. Your technician, Matthew Williams, diagnosed a failed blower motor. I was given Estimate #1402406586 for $1,680 to replace a 3/4 HP PSC blower motor. Because of the substantial cost, I obtained a second opinion. The second HVAC technician found a clogged condensate drain, cleared it, replaced no parts, and charged me $225. The AC immediately returned to normal operation, and the same blower motor Len diagnosed as failed continues to operate. Even more concerning, Len's own inspection report states: "Verify primary drain condensate flow - Yes, condensate is flowing." The report then states the system was not operational and required parts. Had I accepted Len's diagnosis, I could have spent $1,680 replacing a blower motor that did not need replacement to restore my AC. I am requesting: A full refund of my diagnostic/service fee. A management review of Job #1402068744 and Estimate #1402406586. A written explanation of how the blower motor was determined to have failed and why the clogged drain was not identified. I have retained Len's inspection report, the $1,680 estimate, and documentation of the subsequent $225 repair. I am giving Len the Plumber the opportunity to resolve this matter directly and expect a prompt response regarding my refund. Musiliu Aminu Job #1402068744 Estimate #1402406586 read more

My experience with Len The Plumber is not a good one. Waited and waited with the excuse the plumber is running late. I cancelled with them and went with another plumber. No wonder they have such a low rating here on Yelp. read more

This is by far the WORST company ever! I bought an HVAC system from them and I'm left feeling like they got my money and now they have no need to communicate with me. I have some issues to discuss and you can get in touch with anyone at the office, and I mean supervisors and even if someone, like an install manager, Gary, calls you, you can't leave him a message upon returning his call because his mailbox if full! Seriously! Is it because you have that many complaints in a day! How unprofessional. It scares me to death that if I need them in an emergency what that will look like. Absolutely NO customer service at all! Beware if you want to work with a company you can depend on! read more

Len the Plumber, Service Technician Billy Coleman fixed pipes in my basement which were leaking, he was very professional, and nice. Brenda Wilson, Thank You! read more

I was very happy get same day service but if you want them to diagnose your problem for $400 and not fix it, this is your company. Granted, my problem was electrical, but $400 for a diagnostic is beyond ridiculous. read more

I requested an estimate to repair a leak from an external hose bib that developed after a winter thaw. (The PEX supply line runs through a 4-foot tall crawl space under an outside screen porch .) The technician was pleasant, but he did not investigate the cause of the leak before giving me a $2600 quote to replace the entire supply line and hose bib. This included a $734 surcharge for "difficult access," even though I had removed the lattice panel directly next to the hose bib for easy access to the crawl space. Needless to say, I declined the service. Later that day, I removed the foam insulation around the supply line and discovered the cause of the leak: a broken plastic seal in a Shark-bite connector. I replaced the connector -- problem solved. Total cost of my DIY repair was $10 (plus $50 for the privilege of receiving a $2600 estimate from Len.) Caveat emptor. read more

I called LEN because they were able to come out the same day. My furnace flame was fluttering, and it sounded like there was water in the exhaust vent leading to the roof. I suspected a safety feature was shutting the system down, which ultimately turned out to be correct. After inspecting the system, the technician told me it was a "bad install" and that I would need to replace the entire unit, even though it was only a couple of months out of warranty. They quoted me over $20,000 for the replacement. I decided to get a second opinion. The second technician confirmed my original suspicion, explained the issue clearly, and showed me how to fix it myself. No parts were needed, and the diagnostic only cost $150. Needless to say, I'm glad I didn't move forward with LEN's recommendation. read more

I already have service scheduled for Monday, 4/27/26.. The tech was scheduled for 11-2 on Friday, 4/24/26. At 4 PM, I still had not received service, was told tech was running late. The tech arrived so late on Friday that parts could not be gotten. I will have no hot water all weekend. I have to wait until Monday so parts can be picked up. Dispatch insisted on sending one tech when others were available. This tech was not the one who installed the HWH so why did it have to be him? I have spent thousands over the years with Len, I want to know why this was handled so poorly. This needs to be shared with management. This was handled very badly and we have had to cancel plans due to no hot water. I am very surprised at the level of incompetence on this as it could have been taken care of by any tech yesterday. Very disappointed at this oversight and lack of service to a long time customer of thirty years. Ina C read more

Always the best! Friendly, informative, punctual. They always know what they're doing and than some.

RIDICULOUSLY OVERPRICED! I had a simple toilet clog. They came and spent a total of 10minutes and charged $600. Will not recommend due to overpriced service. read more

These guys broke the news that my pipes had been stolen for their copper. They're CPVC. Then they said they were giving me a discount and charged an extra $20. Edit: My Yelp name is "But Were They Polite." This is, in fact, not my legal name. Even if it were, the pipes would still not be copper. read more

I read some of the reviews on here and thought they were a bit exaggerated; so I decided to schedule a HVAC service for a Wednesday between 12-4. I waited all day long at home and no one showed up; I called around 4 and was told that someone is coming but they are might be late and I should not rush the service. I was called back at 6 to be told that the appointment needed to be canceled and rescheduled till the next day between 12-4 giving me 'priority' since the appointment was canceled. I was offered a discount on a diagnosis. Next day: exactly the same story. waited till 4 and then I called and was told the same thing: someone is still coming and I had to wait. So I waited till around 5 or so... and someone showed up. The diagnosis service was okay and the serviceman offered to schedule a consultation for a new installation. They called two days later to schedule a consultation and offered one on Sunday at 1 pm (not a window). Sunday 12:30, I receive a text from the sales person that they have to come between 3-3:40 and that they told the office they cannot make it at 1. So I called the company and the reps said they checked with the dispatch and the sales person will call to talk to me. Not sure about what! I canceled the appointment and then I received a text asking me if I want to reschedule offering "a free estimate for the work." Not sure what the offer is about when the consultation is already for free. All I can say that I cannot judge the quality of the services they perform but very disappointed with the whole experience. I am instaling a new HVAC but not with them. read more

We've had an abysmal experience with Len The Plumber recently. In March of this year, I asked the plumber about three different issues, one of which was fixing the chain in our toilet tank. We were quoted several hundred dollars. I declined, bought a $10 kit off of Amazon, spent 10 minutes installing it, and it has worked fine since then. Last fall, Len The Plumber installed a brand new garbage disposal for us. It recently stopped working. Our scheduled plumber cancelled on us *twice*. On the third scheduled appointment, the technician told us we had to get an electrician to fix the switch. We paid for an electrician, who told us there were no electrical issues, and the plumber could have easily fixed it. read more

Done with Len. Buyer beware. The once might Len the Plumber, whom I and my family have had a long relationship, is no longer our provider. Two plumbers, half a day wasted and still the problem remained unresolved. Turning off the water line to an old refrigerator. In frustration I called an Actual plumbing service who arrived on time, behaved professionally and acted swiftly and competently. More importantly, they actually fixed the problem! On top, the new company was $150 cheaper than Len's quoted price. Trust, yet verify. Attempted to speak with a manger, no surprise none available, message left for a call back. 3 days later; no call back. Done. read more

Horrible experience. One tech came but he said he is the line guy (Dinpuia) and thought I had a drain issue. He took photos and said he would send to the office. A dispatch person of the MD, VA, DC office said a plumber would come that same day. I waited all day an no one came. This was on Tuesday, July 1. I asked to speak with a manager and as message was taken but a manager never called me. Yesterday, July 2, 2025, another plumber, Neal, showed up unexpectedly and took photos and an assessment. I asked him to send the estimate and he said he was unable to send it by phone. All In got was email sent from his Android phone with no text or estimated quoted. To date I have not received the estimate. He conferenced called with Vance in management to relay what he noticed. I told him to leave the assessment with me since it needed to be discussed with my significant other before a decision could be reached. I believe he was inflating the price and didn't want to show the breakdown to us. They finally sent a ridiculous email quote for $2,400 to replace a faucet and tub kit and a few mismatch tiles on the wall. read more

Len The Plumber Heating & Air - Plumbing Near Me - Halethorpe, Maryland

What I like most about Len's craftspersons, (this time it was Chuck and Frank), is that they are breathes of fresh air. Knowledgeable, Competent, and skilled. So I guess I appreciate their willingness to share their knowledge, inform their customers, all without trying to "con" them or sell them anything. When they do the job, it's done competently and efficiently. I trust Len the Plumber and those who work for the company. read more

Absolutely Horrible. Never use these guys. Technician was nice enough, but I couldn't be more disappointed in this company. I would encourage all to find a different company to work with. I have a 7 year old hot water heater that has a small leak from the drain valve. I called to have them come out and give me a quote for repair. $49 diagnostic fee- which is fine- but the technician was here for literally 5 minutes (3 of those minutes were on the phone with his boss) and proceeded to tell me they won't repair the valve because of the age (its 7 years old!) and gave me a quote for a $5,500 new water heater. So 5 minute trip cost me $49 and a quote for a hot water heater I don't need and I STILL have a leaky valve. I feel like I completely wasted $49. The tech was in front of my unit for less than a minute, did zero inspection, took a picture, made a phone call and decided they didn't want the work. Len the Plumber wasn't interested in a small repair (granted it takes a little while for the tank to drain and refill). They didn't want to sit here all day for a small repair and was only interested in selling me a new unit. HORRIBLE read more

This company will never get my business. We scheduled a consult for HVAC replacement instalation and things started off well, our rep even helped us troubleshoot some other issues not related to the HVAC Install. Once we got to the quotes however things took a turn. Not only were the prices extremely high, but the moment I said we'd like to think about it, as we had another installer lined up later for that day, he became incredibly agitated and went into full used car salesmen mode. When we told him who was coming later he became even more aggressive with his pitch. I was close to telling him to get out afyer I told him a 3rd time we just wanted the quote and would decide after the second installer gave us theirs. While not directly saying it, he overtly suggested that if we came crawling back to them after the second installer gave us their quote that everything he offered would be "subject to change" implying we'd have to pay more to use them. Once he knew we were done he grudingly shook my hand and practically ran out the door. My fiancé was so upset afterwards she cried for 20 minutes. If I could give them no stars I would. The second installer who I'll just name because the rep was great was Perry Hall heating and Air and they had installed my parents HVAC. The rep was very friendly and only took about 15 min of our time. He quoted us a price that is over 3,500 dollars cheaper. Needless to say we went with them. The moral here is don't let aggressive sales reps bully you into a purchase, its alot of money and you should never spend more than you need. Stand your ground and if it feels wrong it probably is. Any company who uses reps that try to pressure you into a on the spot agreement should be shown the door. read more

A plumber came to our home Dec 18, 2025 to replace a faucet. In doing so, he chipped our granite counter top. After reporting this to the manager, Greg, he assured me that this would be repaired. They referred me to a remodeling service that referred me to a stone repair company. This is after several phone calls by me. It is an ongoing, difficult effort to get them to repair their mistake, Len the Plumber will not return my phone calls and are taking no action to repair the damage they did to my countertop. What a nightmare. read more

The AC unit was installed on June 25, 2024. The unit stopped working on July 13, 2024. Several unsuccessful attempts were made to Len the Plumber to schedule service. I contacted the sales rep who later reached out to have someone contact us to address the issue. On July 14, a tech from Len's came out and notified us that all the freon leaked out and the $400 surge protector was not installed. He also installed the surge protector. Upon further inspection of the unit by another HVAC professional, it was brought to our attention that there is a dent on the side of the evaporator coil. Additionally, there is an excessive amount of tape on the steel duct. Furthermore, the evaporator coil and the steel duct do not line up as the coil is pushed further to the right of the system. A bad job and regret doing business with Len. read more

My Len the Plumber technician, Richard Duvall, was excellent! He was very courteous and friendly, but most importantly, he was super knowledgeable and professional about the repairs that I needed to my HVAC system. He checked everything thoroughly until he discovered the problems. He took photos of the damaged components, showed them to me, and explained them in a way that I could understand. He also explained why getting a service plan was a good idea. I'd been lazy about getting a plan, but I was so impressed with him that I went on and got it. He got to work quickly and got the job done. He went back to double check that everything was working properly. Richard was very detail oriented. This was an A++++++ experience all the way. From now on, every time that I see a Len the Plumber truck out in the wild, I'm gonna wave. Hope the driver doesn't think that I'm crazy! read more

Happy to share my story and provide a contact for anyone who has been ripped off and still needs help. I don't want the company that helped to be linked in anyway to Len the plumber. Len the plumber tried to rip me off. I was without heat they sent a kid to my house to "fix" it 3x Finally they sent what I assume they believed was their big dawg He didn't know I had recently had my valve replaced and told Me it was the main issue and he wanted to charge me $1800 to fix it but offered a discount of $300 since they have been to my house 5x in a week The company I used told me the issue was not what they said and fixed it for 1/4 the price. When I let the tech know what the issue was - he said oh yea I was gonna mention that today when I came.. i do not recommend using this company read more

On 5/22/25 I experienced a sewer backup. Over several days Len The Plumber performed work for which they charged me $18,390 and promised me a life time warranty. On 7/29/25 the sewer backed up again. Now Len The Plumber has sent me three invoices for another $503 and I have received three dunning phone calls. If I had seen all of these negative reviews, I would not have called Len The Plumber. read more

If I could leave two stars for this group, I would give 5 stars to the workers and 0 stars for the company, so I'll hit the middle at 3 stars. I also should have read the reviews. Instead of sending out the plumber for a floor drain clearing, they sent an AC guy who arrives the day after the company cancels the first appointment. He did not have a drain snake. I get that this happens. Long story short, paid out over $1100 and the drain is not cleared. I did have him install a auto shut off if the drain backed up. Guess what, it flooded twice. After finding out while snaking the drain, that the outside drain pipe had separated, and was it was reconnected and repaired, but it was going to cost another $400 + to re-snake the drain now that the pipe was reconnected. That is way too much money to pay twice for a distance of about 15-20 feet. Had to cut my losses at that point. Once again, the workers who have no control over price were great, but I'll find another local company for future work. read more

I called them for 2 clogged drains...each drain was $599 ...the second drain they couldn't unclogged before they could do another $900 in work. I refused the addt $900 in expense. So the plumber spent one hour to clog one drain and attempted to unclogged the second drain but failed - charged me $1198 . People be aware. I called the condo association and they sent out a plumber to unclog the second drain...no charge -HOA paid for it. I spoke to the condo association's Plumber and he said Len the Plumber prices are crazy ... He unclogged the second drain and did the repairs in one hour .. Len the Plumber wanted a whopping $1500 to do the repair. Charging customers $1000-$1500 hr is just crazy. This was my first time I used Len the Plumber and will be the last. read more

I would give negative stars if I could. My 96 year old step father's heating system stopped working today, of course on a Sunday, and of course when we are experiencing record low temperatures. He lives in Annapolis, MD and called Len The Plumber believing they're probably the only company that would come out on a Sunday. He was told a tech would be there today by noon. Great news, except that It's now 5:30 pm and still no one has shown up. The worst part though is that he has called at least 4 times to find out when or if anyone will show up only to be told the tech is running behind. He's worried sick and that's all they can tell him. Clear communication is key and had someone told him he'd be waiting this long he might have been able to contact someone else. Avoid them! read more

Excesssive pricing, and of the three technicians who came on different visits, one was dishonest. I'd look elsewhere.

No wonder Len the Plumber has such low ratings. In the fall I called about water leak on my well check valve. Just a small drip leak. I waited them to show up about 4 days. I heard all kinds of BS, the guy was gonna be late because of an emergency call. They had to cancel because of emergency calls. They thanked me for patience and offered discount on the service when they get there. 4 different days of listening to all that crap. So I just let the leak go, They never showed. I decided to give them another try, because I had a good experience years ago. Today the plumber in the truck called me and said he was on the way, be there in half hour. 10 minutes later another plumber in the truck called and said he was on the way. I told him somebody already called and said he was on the way. So the second plumber said, "i'll call dispatch". The second plumber called back and said the first guy was getting the call. So I thought that's cool. But NO. 10 more minutes later, dispatch called me and said , the first plumber was called on an emergency and wouldn't be here til later. I can't wait for the next call to hear about more emergencies. If they don't make it here today, I'm done with these clowns. I have adjusted my schedule twice today to accommodate these guys and the bullcrap stories are starting. read more

I needed a plumber urgently, Len the Plumber sent a salesman that did nothing but inspect the issues and email us options. We had to pay $50 to get this slick sales guy just to show up, he left and nothing was fixed. I've got an actual plumber in the past from Len, but they must be changing for the worst. Their top priority is to get your money, not do the job. I will never do business with Len the Plumber again. Their marketing is slick, but they didn't answer our calls and didn't do the job. read more

I was a potential new customer. I scheduled an appointment and had more than one call with the company to discuss my needs. My most recent call was the day before the scheduled appointment. I left work early and sat at the property for 3 hours because they were supposed to come within a 3-hr window. No one ever showed up. They didn't even call to tell me they couldn't make it. They were a no call no show. They are a waste of time and I do not recommend. Update: Then when I call them out, they lie. "They can't find me" on Yelp, but they keep calling trying to reschedule. This is a shady company. Now, I'm glad they didn't show. read more
