Basically deserves no stars. They are high way robbers. Avoid. Charges exorbitantly even when they do not replace parts or any thing in addition to dispatch fee and fuel charges. I have used them before but will not anymore. Update : WM Henderson followed up the next day and agreed with the complaint and refunded the hourly charge that was added. So thank you for following up, much appreciated and I will add a star for that.

I don't usually leave negative reviews, but I really felt like I had to for this experience. My toilet overflowed and I had Henderson come out to clean out the pipes. They knew I had a history of root problems, yet this time told me they could not find any roots and charged me $500. 2 weeks later, my toilet overflows again and Henderson said this isn't covered.

I wasn't about to use them again so I called roto rooter and they came out, cleared all the roots and even ran a camera for $500. Henderson gladly took my $500 and did nothing, not even run a camera. I will not be using Henderson again. Beware of this company.

Yesterday I had "Steve" from Wm. Henderson at my home for a plumbing problem. He worked tirelessly and all day on the problems in my home. He did an absolutely excellent job. He was kind, respectful, and extremely helpful. I recommend Henderson very highly for your plumbing needs.

My Tech was Paul. He initially did the diagnostic and was able to figure out what the problem was. He was so great that I opt to have him come back and do the repair. He's professional, kind and paid attention to detail. He arrived on time for each appointment. Today was a bit cold, I felt bad that he had to be outside fixing my unit. Although he was col he still did an amazing job. The price was fair and the customer service was great too. WM Henderson has gained a loyal customer, I would recommend to family and friends. Thanks Paul + WM Team. :

They installed a heat pump conversion from oil last March. It all seemed fine until September when water started leaking through my living room ceiling. They cam within 24 hours to stop the leak and admitted that it was an installation problem. People came out to the house and repaired the ceiling even though they found mold on the attic side of the ceiling.

This kept going on and on. I lived with mold in my house for five months before everything was remediated and the ceiling replaced. I wrote to Henderson complaining. Just think about it.all if the customers whose systems were installed correctly didn't have to take unpaid days off of work, their living rooms weren't construction zones and they didn't have to live with mold.

At the end of the day it got fixed, by put I strongly feel I should be compensated. I never even received an apology. They were great when they were taking my $17,000.afterwards, not so much.

Henderson installed an oil furnace and AC over a 2 day period. Joe, Andrew, and Joe were great. They addressed all my concerns and question, we're neat, and on time. I could not have asked for a better installation experience.

Our primary concern is with Steve in the billing office. We have typically had a positive experience with the actual techs who come out to the house for repairs. But our experience with Steve has been bad enough that it doesn't feel worth it to use WM Henderson any more. Steve has been aggressive, unprofessional, and rude in any interaction we have had with him.

We had a repair done on our heat a year ago in March 2021 and were told at the time that they were going to waive the cost because of the trouble we went through with the repair. WM Henderson misdiagnosed the problem (they said it was the control board). We went 7 days without heat until they were able to diagnose and repair the actual issue (a broken inducer motor).

While this was going on my husband tested positive for COVID so we and our two young children had to quarantine for those 7 days in the cold. We were as patient and understanding as we could be. We were so grateful when the heat was finally fixed, and then even more so when WM Henderson told us that they were going to waive the balance for the service.

It made such a difference for us. Now, a year later we have started getting invoices in the mail stating that we owe almost $1000 for the repair that occurred a year ago. Steve is the only person in billing who will talk to us about this invoice. When we asked Steve why we are getting these invoices a year later he had no answers and said the best he can do is give us a $200 "discount".

This may sound generous, but after being told we didn't owe the money in the first place it's really disappointing. Steve has threatened to send our account to collections and when we've asked to speak with a manager to get clarity on why we were told we didn't owe for the service Steve has told us there is nothing they can do for us. We finally paid the balance today (3/16/2022) because Steve's calls were starting to alarm us.

We didn't want to be bullied or harassed by him any more and there was no one else who would help us at WM Henderson despite our attempts. This was a terrible experience for us and it's not worth using WM Henderson any more because of it.

I had a good experience. They came out on time and did the job well. I desperately needed a new toilet because the old one was overflowing. He cleared the blockage and installed a new one w a shut off value too and I am so happy. It didn't take long and the price was fair.

We were customers for 10 years but no more. Although they have always charged high prices, we thought that they were at least honest but they flat out lied to us during our last service call. Our heater (that we purchased from them) stopped working in 22 degree weather. They came the next day and diagnosed a faulty blower motor. The part was under warranty but we would be charged for labor - $788 which seemed high.

My husband called the service department and was told it would take 3 to 3.5 hours to repair which made the price seem a little more reasonable. The service manager even offered to apply a $50 coupon to the total bringing it to $728. What a great guy right? The technician arrived the next day and completed the repair in less than one hour. I have since found out that there is no way that repair would EVER take 3 hours.

The service manager lied to us and took advantage of the fact that we were without heat for 4 days in 20 degree. We were essentially charged $728 an hour for labor. They also have a neat trick where they provide you a bill that simple says, "Heater repair". No breakdown of charges or time spent at all. Nice. So goodbye, William Henderson. After 10 years, a sewer pipe replacement, repairs for a rental home oil burner, many yearly checkups and a new heating system, we will be finding a new heating company. Just in time too, cause we need a new air conditioning unit.

We have a 3 zone, forced air oil furnace system. Installed 16 yrs ago. About 5.or 6 yrs ago is stopped working properly for one of the zones. 2 companies and it was working right, but better. This heating season, now two zones aren't reaching to main floor after a couple of calls, one person and a company that the tech recommended Henderson. 2 techs came, diagnosed and ordered parts and 2 days later came and fixed it. Jeffrey and Steve came out and diagnosed and Jeffrey and Joe fixed it and the were all great. Two hrs, maybe to access the problem and 2 to do the work. Will use again!

When we needed something done and could not wait for our home warranty company we contacted Henderson. their response was quick, effective, and professional. 25 year old Hot water heater repaired and a year later replaced. converted to gas from oil heat and the job was done on schedule, clogged sewer pipe done in a few hours as promised. every worker we have spoken to has gone above and beyond explaining everything and the work is impeccable.

My heat went out on a Saturday. Henderson was here the same day. Although they couldn't find the problem in the zoning, they made sure that I had heat through the entire house and came back Sunday. (all for $89.00) They did find the problem it was the zone control. I google the part and for a four zone system the part alone was $900.00 + labor + dampers.

I didn't ask Henderson for an estimate and since my system was 22 yrs old, I decided against putting that kind of money into it. I ordered a new system. Price was good for a Lennox furnance and a brand new 4 zone heating system plus new dampers. All guaranteed for 10 yrs! parts and labor for 5 and parts for 5. Everyone was so nice. Workers cleaned up. put drop cloths down and answered every question. Couldn't ask for better.

Our furnace stopped working during the last snowstorm. My husband spoke with his HVAC friend over the telephone and it was determined to be a faulty flame sensor vs. hot surface igniter. We were going to order the piece from Amazon for $35 but it would not come in for a week. His friend walked him through how to clean the flame sensor, so that was already done.

We decided to call WM Henderson who said they could repair it the next morning. They came and stated the flame sensor was fine but the igniter was not, as we suspected. They proceeded to charge us around $627 and told us that $500 of that was the cost of the part, which is not true. I was told they were going to send me a receipt via email which I am still waiting for.

We are very perplexed as to the cost of this service visit, as we have called other HVAC companies since this experience and they have stated this is GROSSLY overpriced. I am still waiting for a response from the company. So, at this time, I tend to agree with another reviewer that the price appears to be bumped up three times what it should be.

Steve was excellent. He explained everything. I even asked if we could get a senior discount and he went to the boss and they gave us a discount. That was very thoughtful of him. What impressed me the most was that he found some inconsistencies and it did not change the contract price, in other word he did not nickel and dime us. The contract signed was the final cost. For being so young he acted super professional with a ton of knowledge. He is an asset to the Henderson company.

Henderson completely saved me last year after a different "plumber" working on my house fell off the face of the earth after demoing a lot. It was a house I had just bought and was trying to move into, but couldn't because of the other plumber disappearing with the house in disarray. The Henderson team quickly diagnosed all of the issues and repaired everything in a timely manner so that my family could move in. I will definitely use them again and highly recommend them.

We used Wm. Henderson for a leak from our second floor bathroom to living room ceiling. It was a Tuesday night at 7pm. After calling seven other companies and leaving messages with answering services, Wm. Henderson not only answered right away, they sent out a tech within 20 minutes. Dan was excellent. He quickly found the source of the leak and answered all questions.

He helped me find a restoration company to clear the water damaged ceiling. Wm. Henderson reserved a spot so that we had an appointment all set once the restoration company gave the clear for plumbing repairs to be made. Dan and Chris did the necessary repairs and were wonderful. They did great work and replaced the outdated parts for our tub. The whole process with Wm. Henderson was smoothe in what is otherwise a stressful situation for a fairly new homeowner. The customer service was excellent. My husband and I will be using Wm. Henderson for all of our future plumbing needs.

I've been using WM Henderson for over a year now after tirelessly going through other service providers. For all of my needs they have been easy to work with on DAY 1! From plumbing to heating, I've been impressed and happy each time they visit for minor or major repairs. They actually do what they say they are going to do during their visit and in the time frame they indicate (which is important when you have a busy life)!

All of their professionals are exactly that, professionals! They all have excellent education and training (clear in the work they do and the way they communicate) and have been just downright good humans. Ya, I will continue to use them.

The service and quick response I received from Wm. Henderson, Inc. exceeded every possible expectation. I called late Friday afternoon (5 PM), the day after Thanksgiving, with no hot water. I received a quick call back, and a technician was dispatched and arrived within about 40 minutes. The technician, Steven Blaskovich, was really wonderful. He quickly identified the problem, had a new water heater delivered while he drained the old one, he removed my old water heater and installed a new one which was up and running by 8 PM. Absolutely outstanding service in every way! I will highly recommend your service. Thank you so much!

Technicians came to the home to fix all of the leftover issues that remained after our oil-> gas transition and new HVAC system. I think the installers were great in a lot of ways but just didn't finish the job well. These most recent technicians (Jude) were amazing. Thanks so much. Service: HVAC repair

Our furnace was working fine and then after these guys serviced it Thursday night. Unfortunately, Friday morning it stopped working. I called and was given appt for Saturday night at 6pm the next day! They made an appointment for 24 hours later! Then they came and took about five minutes to look at it and said it's because our furnace was too old they might not be able to get the part- not taking any responsibility for the "furnace not working?" They will be back Monday- to replace the nozzle.-Monday they sent a different service tech. who was able to fix the issue and able to talk me through different solutions instead of having to replace the entire unit. I was very frustrated that the unit stopped working and we had no hot water or heat for 3 days but I am glad they were able to come back and fix the issue.

A pipe in our shower broke on a Monday morning and it was the only shower in our house. It turned out all of the pipes were bad. I called for estimates and no one could start for at least a month or two. Wm Henderson went above and beyond. They fit us into their already filled schedule. They gutted the bathroom and had a shower installed within two weeks. The whole bathroom was completed in a month. I am so grateful to them! Dave, Nick, and Paul were wonderful to work with!

We were so very happy that Henderson could help us with a leaky pipe whose damage was not discovered right away because the water was leaking into a part of the basement we seldom use or see. Ugh! We call Henderson right away and they were able to send someone early the next morning. Their plumber, Cyrus, was capable, polite, pleasant and kept us informed as he was working. Happy to be able to recommend highly!

Michael was fantastic. Our water heater was in a very difficult spot. He not only got it replaced, but did so without damaging anything at all, which I was prepared to tolerate knowing how badly positioned it was. He went above and beyond with making sure everything he touched was left better than he found it, and was an excellent communicator. We are very happy with the quality of the work, but to mention the added features our home was lacking previously due to age, like proper shut off valves. Highly recommended.

Had a clogged main line and had called another plumber who was unreliable and never showed up. Remembered seeing WM Henderson trucks in our neighborhood before so we called and they had great customer service and got us scheduled the next day with a window about 4hrs. As we were told would happen, The technician called when he was on his way with a time estimate.

The plumber who came, Keith, was friendly and kept us updated when he hit traffic and showed up still within the first hour of the window we scheduled for. When he arrived he was friendly and very informative. We thoroughly checked out the problem, gave us a price and we agreed. We were told an initial dispatch fee (I think $65) that was charged to have them come and diagnose the problem. Then, they give you a price estimate and if you agree to have the work done, the $65 fee is then waived. Keith quickly got his equipment and dealt with the clog.

He gave us tips on how to avoid a clog and checked by flushing every toilet before leaving. We had a water hammer noise he also checked for us before leaving and gave price estimates and info on that for no additional charge. Would definitely recommend this responsive company who showed up on time and was informative and friendly.

They do excellent work at reasonable prices. They aren't always the least expensive, but their quotes are complete, which means no unpleasant surprises, and their recommendations reflect their knowledge and desire to do the best job possible. We have used them on plumbing, heating, and A/C jobs, including a commercial sewer line replacement, and have been happy every time. I have recommended them to others for all types of work, big and small.

Excellent experience following loss of AC last night, in the heat of this summer. Erik Medd was professional, knowledgeable, and on time today. He troubleshot, fixed the problem, and discussed expected life of. the unit to inform future decision making. I absolutely recommend Wm Henderson based on his work. Our toughest critic thanks him too. Her vent is working again :

I can't even tell you how disappointed I am by this company. Rude, arrogant, condescending, dismissive, smarmy, and patronizing barely skims the surface. Here are just a few quotes from the last conversation I had with a man called Jackson. Is this his first name? His last? I wouldn't know because he wouldn't tell me. When I asked for my issue to be escalated he also wouldn't tell me the name of his manager or who he was contacting.

He actually flat out said I'm not telling you who I'm contacting and when/if they will even call you back. and. no one called me back. My guess is he contacted no one. The alternative to that is worse, because it means he did contact someone, and they were as dismissive as he was and didnt even bother to call me. At any rate, some of my other favorites from our conversation. "The plumber didn't agree with you he just said it to get out of your house." "You can keep telling me all you want, but I Dont know what to tell you." "You can't prove that we did this." If you're a homeowner looking for an HVAC company and you are reading this, do yourself a favor and find another company to work with.

I would recommend they are services for plumbing and heating they are high but isn't every plumber and heating company. However I would've never ever use their services for my Ductless cooling system I had them come out to do an assessment just to make sure everything was working properly for the coming heat and what I found was they didn't do anything they claim to have clean the vents which you can do yourself and when I asked specifically if there was enough coolant in the system because I had a previous problem with that I was just advise oh yeah it's fine.

Upon turning the system on which they did not do it was noted that there was insufficient cooling in the system which meant once again there was insufficient coolant in the system so that tells me they didn't do jack shit and I would never ever have them come out and check my ductless system again so before warned

This company is a joke. They Ripped me off for $60. They sent an unqualified inept person who came here and IMMEDIATELY started adding up some absorbed cost for a simple job to install laundry hookup. He was talking crazy, like having the pvc piping outside/exposed.& said $7200 to put inside the wall, plus more if i wanna get permits, but "I dont have to get permits if I dont want to", he said.

He couldnt remember where I wanted the hookup to go and kept suggesting that I put it somewhere else. I wanted to kick him out from the gate. Their fee was $65 and he didnt have change for $80 ( 4 $20 bills), so we settlled at $60 to get him the F out of my house. ABSURD! NEVER EVER USE THEM, NOT EVEN FOR AN ESTIMATE! NO STARS IF I COULD

My furnace broke (8 years old) but had two years left in the parts warranty. They convinced me to buy a new one. Since then it has broken twice a winter - now on the 3rd winter. Basically every time them temperatures go into the 20s it breaks and we are stuck freezing - one time for 4 days in freezing temps we had no heat. I've had to have them come at least six times to keep working on it. They do not seem capable of solving and either sold me a lemon or don't know how to install furnaces properly.

I called them about my leaking outside spigot on Monday and it was fixed Tuesday morning. They had to cut a whole in my wall and add a shut off valve in very tight quarters. The put a cover on it so it looks nice. They were pricey but I'm happy the work is done.

I requested someone to do maintenance on the boiler because the radiators were barely warm on the first floor and cold on the 2nd and 3rd floor. Someone came out and found the water pressure was low, so he did not do the maintenance. He was very pleasant and showed me the lever to open to add water to the system but he did not do it himself. I asked about their maintenance program and gave him my credit card.

He left and as soon as I added water the pressure went high and flooded the basement. He did not do any maintenance because there was a leak that had to be fixed first. I got another company to come out who realized immediately that there was a pipe broken that supplied water to the boiler. I emailed Henderson the next morning and told them to cancel the maintenance agreement.

They refused. I insisted and they said they would send me a check for half the amount. They should have refunded the entire amount or just not processed my credit card. Their response? We do not refund maintenance agreements. I was not told that nor was I provided with any terms. My experience with Henderson was apparently not uncommon judging from other interviews. Let the buyer beware!

DO NOT use this company they are totally overpriced and will over charge you by at least 3 times the competitive rate for plumbing. Dummy me signed the estimate for a kitchen faucet replacement that took 35 minutes $862 later, mind you with my $65 applicable service fee. Called into the CS department after getting my invoice that was not itemized with the charges for the faucet and labor. Lindsay the CS manager refused to provide me with me the breakdown, told me it's a flat rate. GREAT! WHAT'S the flat rate?

Basically told me whatever the tech feels like charging. How is this legal let alone ethical. She applied the $50 coupon as that seems to be their solution for every complaint and removed my service agreement after she engaged with a battle of "he said she said" over being referred and the costs. Totally unprofessional! The end result- still no itemized invoice.

I have never in my life received any receipt that did not include itemized charges. Totally UNETHICAL. I had to file a complaint with the Better Business Bureau in order to get my charges investigate. NEVER AGAIN.

I have an annual contract for heater and air conditioner. I had an appointment scheduled for the heater maintenance today and they called to cancel. The same thing happened in the summer with my appointment for air conditioner maintenance. They do not seem to care about their customers time. Needless to say I will not be renewing my contract.

These guys showed up initially on Thanksgiving (an emergency ) and stabilized us. (That bastard Len the plumber said he didn't come to our location. so much for the "only way.") Henderson made an appointment to return and apply a permanent fix. They called and rescheduled it for two days later, but fortunately, that was OK as I work out of my home.

While they were here, we also had them install a new replacement toilet. Crew was efficient, communicated well, and left the job clean. They are not CHEAP, but when it comes to plumbing and electrical work, it's not a good idea to lowball. Get it done right the first time.

WM HENDERSON PLUMBING BROOMALL, PA I recently needed a plumber because my house boiler's pilot light would go off every day or two, needing to be relit by me. I'd seen quite a few of "WM Henderson Plumbing" trucks and decided to give them a try. A young man examined my boiler and after saying it didn't look like anything was wrong took another look by pulling out the thermocouple (a short straw-size, vertical protrusion) and the pilot light and pronounced that the proximity of the two to each other was the cause of my boiler's on-and-off-again problem.

The thermocouple has to be close enough (yet, not too close) to the pilot light to heat properly and, thereby, via proper signaling, keep the boiler going. My boiler's thermocouple was slightly out of range, i.e., not being hugged enough by the pilot light, and maybe not sensitive enough (I was told); thus, his cleaning/"sanding" it with a folded dollar bill.

But that didn't work. I was told I needed a package that would solve this problem and it would cost $521 total. And that would be on top of this $85 diagnostic visit. I asked, "Why don't you just adjust the thermocouple via bending it closer to the pilot light?" His response: "It can't be bent." I declined the install in order to seek a second opinion, and it just so happened, not from another plumber but from a plumbing-knowledgeable chess club friend about a week later, after a few more pilot light outages.

My chess friend--who doesn't like plumbing costs either--looked the situation over and told me that he would very slightly bend the thermocouple closer to the pilot light. "But the plumber said it couldn't be bent, " I informed him. "Nonsense, " he answered, "it can be SLIGHTLY bent and that's all you need." To make this story short: The boiler has been working fine for three weeks straight without turning off--and I saved $521! Moral: Attractive and clean trucks do not mean the service is going to be what you expect.

Hot water stopped working so I had a feeling it was either the thermostats or the heating elements. Tech came and replaced both thermostats when only one was faulty and said the elements were fine. $500 dollars later, the same issue arises. I look into myself and find an electric wire that was never reattached and also find out the top heating element is shorting which was the culprit the entire time. $500 dollars wasted for $30 dollars of parts and no solution.

A Henderson technician was here to tune up our heating system boiler. After finishing, he recommended installing something that would prevent corrosion inside the boiler. He said it would cost $473, so I assumed it was some sort of device. I said ok. Ten minutes later he came up and said he was done. turns out it wasn't a device, but rather a liquid additive.

I asked why it was so expensive, and he said "that's what Henderson charges." On-line, the liquid costs $25, so it presumably cost Henderson less. I called Henderson to protest the extreme cost for 10 minutes of labor by a technician who was already here, plus $20 materials. They first refused to lower the price, but eventually lowered it to $273, which is still a rip-off. AVOID THIS COMPANY.

I engaged Henderson over another plumber because they advised me that their price included fixtures which the other plumber did not. Henderson was prompt. Their work was excellent. But - they worked their way around the fixtures that I requested. I wanted a soaking tub. They installed a regular tub. I wanted a specific hand held shower. They installed a fixed shower.

I showed them samples from Kohler. They installed Moen. In fact, they seemed to have a thing going with Moen. Then too, after the major work I had some minor plumbing requests - but for the little things I never saw them again. Yes, all they did was perfect. It just wasn't what I asked for. "Caveat Emptor."
