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." read more

Heating company of 10 years said I needed new heater. Called Henderson for a second opinion. Anthony came and wrapped the heater and replaced ductwork for $1400 and my house is warm for the first time in 3 years read more

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. read more

Called because heater wouldn't ignite. I had spark and thought it may be a nozzle or filter. Guy came and looked and said nozzle was clogged and would give me a price on replacing and changing filter. Came back with price of $473 for a nozzle and filter which was ridiculous but I needed it fixed so I agreed. He does the work and then tells me there is water in my tank so the heater still wont work and that he tried to drain some off but no luck so I need to have my tank drained and refilled with oil and they don't do that so leaves with it not working. I go down and prime it about 4 times and got all the water out myself. Complete rip off, will never use again. read more

I've used Henderson previously for their annual check-ups to see whether I have any serious issues with my heating or AC systems. Honestly, I believe they under-price these services so they have the opportunity to enter your home and write up estimates for much costlier repairs. For example, on their last visit it cost me close to $400 to have a simple $30 capacitor replaced on my heater (come to think of it, they did the same thing a few years back on my AC condenser -- the technicians keep them in stock right on their trucks -- hmm). But that's relatively small compared to the other estimates. Recently they said I needed a new 80 gallon water heater and that would be close to $5000 (with their coupon). Seriously, almost $5000??? After reading the comments on this thread, I'm pretty sure I'm finished using these guys. read more

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. read more

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. read more

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. Dave G. - thanks for looking into this. My name is Andrew Perry and my Zip is 19342. read more

They should change what the website says. More importantly make sure the first contact personnel with the answering service knows the areas what they do and don't service. read more

I had these guys put in an A/C system for me. It was a High Velocity system. They did not know what they were doing. I had trouble from the first. The system leaked a lot of cold air into a crawl space and they just acted like that was normal!!! I had to force them to come back and finish the job. Then six months later after not being happy with the system I watched the manufacturers installation video. Boy I wish they had too. They obviously had not watched the video because my system was put in wrong. The owner is awful to deal with if there is a problem. The rest of the staff is OK. Some are even good to deal with. Over priced and self important. read more

Per my previous email, no one ever reached out like they promised to do via Yelp. They just say that but do not follow through.

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. read more

Ridiculously overpriced quote. Over $5,200 a Kitchen sink and Bathroom. With nearby access to the septic. That will take 2-3 days to complete for 1- 2 people. We still have the final hook-ups. Please explain why such an inflated price? Do you think we're fools?? Have tons of extra money and wish to give it to you? It a joke? It a mix-up of jobs? We are desperate? My fiance thinks is pure price gouging. You probably have too much work and thought you would highball it just in case one of the above was true? We resent Henderson wasting our time, then insulting us with a grossly out of line proposal. The next quote was $2,500 and am waiting to hear back from others. read more

The 2 star rating from what I see on yelp means "Meh. I've experienced better". And, after getting quotes from several other local plumbers for similar levels of work I think that applies to WM Henderson. We've had a few plumbing issues in our house since we moved in 5 years ago. At first, knowing nothing about home improvement, plumbing, or plumbers, I had no idea who to contact. But I'd seen the WM Henderson vehicles around and figured it'd be worth it to go with a local company. They charged what they charged for some routine maintenance type of stuff and I kept them in mind for. Their staff was nice enough. Flash forward to a more major issue I had in a bathroom. We had a section of pipe that needed to be replaced, about 2 feet and new stub outs for hot and cold water to a sink. We also needed a drain line replaced and tied into our sewer stack in the same room. I took out the floor in the bathroom to expose the studs so there were no issue with access. I priced out the parts to be around 100$ Henderson quoted me $1,300. Another local plumber with excellent ratings on here quoted me $650 which at 100$/hr seemed far more reasonable to me. I priced Henderson's labor out at more than 200$/hr considering the parts. I work in an industry where if bids came in that far off we'd have a problem, a misunderstanding as to the scope of work. What I've come to realize however is that Henderson is just very, very expensive. Please consider going with a more local plumber. I could have saved hundreds if I did so sooner. read more

Wm Henderson Heating and Air company all the employees and staff are very friendly. I rate them a perfect 10.

Showed up and wanted over $700 for shut off values! They knew we had no water and took advantage of that. Then proceeded to tell replace all copper pipes! They are a rip off. Do Not Hire!, Rip off! They take advantage of people. read more

We totally got taken advantage of, and it's sad knowing this sort of thing goes on and its hard to find trustworthy people these days. We had called WMH when our gas water heater wasn't working back in October. The technician, named Steve K, didn't bother troubleshooting or even touching the heater, but just said "Unfortunately, I know this model well, it's discontinued and when you have water in your basement they are ruined." I explained that the heater was only 3 years old and there was a water leak in our basement, but not enough to submerge anything. He then explained that even the slightest bit of moisture is enough to get sucked up from the bottom and completely ruin the heater. He then quoted us $1339, and pressured us by saying the $95 service fee will go towards it if we agree but we'll lose it if we decline. Glad I chose to decline, I just had a feeling something was fishy. So the next day I called Bradford & White tech support and told them what the WMH tech said, and they called his claim "ridiculous". I also called 2 other local HVAC companies and they said the same thing, and they couldn't believe that he didn't even take time to open the thermostat or look at the burner. We told WMH this, and they said "We stand behind what Steve told you and will not come look at it again, but if you still want to buy the heater from us we'll deduct $100. We did not have enough to buy a new heater, or risk another $75-$100 charge for another HVAC tech who might say we still do need a new heater.... so we endured 3 months of having no hot water (in the winter mind you) while we saved for a new heater. We were really stuck, and we had to get used to heating big pots of water on our stove, carry it to our tub, and using that to bathe. Finally, in January, our neighbor had a handyman that they knew come check it out. He came over, opened the unresponsive thermostat, started properly troubleshooting, cleaned some wires he said looked dusty, and got the heater working in no time. He charged us $20 for the hour he was there since he was friends with our neighbor, but we gave him $100 for his honesty--and for saving us $1300. W.H Henderson, please stop trying to take advantage of people who are not familiar with HVAC tech details, it's not right. Some people go through financial setbacks like us where even $100 is too much to throw around. Please encourage your employees to do the job they were asked to do (fix things) rather than upsell and make money/bonuses/quotas or whatever. PLEASE tell them honesty will be better for business in the long run. read more

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 read more

I've been using Henderson plumbing for years but it seems I'll need to find another plumbing service. I feel their prices have become exorbitant. I was charged $2600 to replace a toilet, shower head, and 8" faucet. I purchased independently all three including a new shower valve. If anyone has a plumbing contractor who's efficient and fairly priced please let me know... read more

Wm Henderson has serviced our furnace and AC system for years. They are always on time, courteous and do a good job. They are also available on short notice. They may not be the cheapest, but they make up for it with good customer service. Sometimes, that's the difference. read more

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. read more

The service was quick and efficient, they were able to give me same day service and everything from office staff to the tech was great!

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! read more

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. read more

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. read more

We called Wm. Henderson to come take a look at our heater when it stopped working suddenly. This has happened before, and the cause was a bird flew into our chimney and clogged the system. We hoped that it would be the same this time. So their tech comes out, and check the heating system for a matter of 5-8 minutes, and says that we have a bad motor. It would cost $917.00 to fix and he also cleverly let me know that there could also be other issues with our system that we would need to fix to get our heat back on, but he wouldn't know until the motor was replaced. At this point we were going to give them the go ahead to make this repair despite warning signs like the quick diagnostic, and being asked by the tech if the issue with the heater is large, if we plan on getting it fixed right away. As if he was making sure we were going to say yes to any problem he came back with. What changed our minds was the previous warning signs and the $307.00 bill for the 5-8 minutes he spent inspecting our heating system. Over the phone we were told that it was $95.00 for them to come and take a look. When I told this to the tech, he says" Oh, that's just for us to knock on your door." Which makes absolutely no sense! At that point I felt slimey even speaking to him and felt I was being scammed so I told him I only had $100.00 on me and could not get more money for him. So he said he'd call and see what his boss says. 5 minutes later he comes back and says that just the $100.00 is fine... So as you can guess at this point I knew that at the very least this tech sent was a crook if not the whole company. Now we find another heating company to come in for a second opinion. This tech took significantly longer looking at our system which felt good. Then he gives us his diagnosis... A bird was stuck in the system!!! Your motor is completely fine!!!! He removed the bird and all was well. I'm so sorry for this as I don't normally write reviews, especially to bring anyone down, but this I could not let go. I understand mistakes are made, but to me this was clearly no mistake. This was done to take complete advantage of my family, and throw a large bill over our heads. Completely unacceptable to do to honest homeowners just trying to have a working heating system for the coming winter. I would suggest never using this company for any work if they take advantage of people like this. I will call Wm. Henderson and speak with them about this. If they don't blow this off and actually look into the situation I will edit this review somewhat so that what could have just been one tech's crookedness doesn't bring down his entire company. read more

As first-time homeowners, it would have been very easy for Henderson to take advantage of us -- we had no idea what we were getting ourselves into with a 100+ year old house, and we had no concept of what any repairs / maintennance would cost. A year into it -- we have unfortunately suffered numerous HVAC emergencies, and thank goodness Henderson has been there to bail us out every step along the way. Most of our situations were based on desperation; the previous owners had used Henderson so when we were in a bind we just moved forward with the people who we felt already had a good handle on our weird old house. But, for decisions that we could take our time with (air conditioning installation, namely) we did our due diligence and got multiple estimates from local providers. Despite all the price-criticsms described within other reviews, Henderson actually came out slightly less than the other bids, which made it an easy decision for us because we already knew first-hand that their work, reliability, and knowdledge is impeccable. Due to our ongoing maintenance issues (sadly, this seems to be just par the course with old houses) it was a no-brainer to sign-up for Henderson's service plan, and with all of the other craziness of life it is relieving to know that when it comes to any AND all HVAC situations, we've got our guys. read more

Professional staff and responsive management. Service is prompt. Only complaint I have is pricing on parts.

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. read more

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. read more

My tech mike was great. The issue I have was the young lady Olivia in the office. I had called earlier in the day to schedule my heater to be serviced. Apparently I was not using the correct terminology as she so kindly pointed out that was is considered Maintenance. She said they don't not schedule those appointments on the weekend and the next available appointment would have been mid December. I told her I would call back Monday to schedule an appointment for maintenance. Later I found out the temperature would drop to 32ﾟ that night so I decided to turn the heat on. When it did not come on and I sought help to light the pilot but it would not stay lit. I call the office back to get an emergency appointment and spoke with the same young lady who gave me attitude as if I was lying about the situation. I have an infant and a young child and dropping temperatures and did not have time for her attitude. She call back to tell me that there was a technician that could be there within the hour but I had left to go by space heaters because I did not believe she would send a Tech out. Someone was speaking to me and she proceeded to yell both of you could not speak at the same time. I admit she was on the car speaker and it can sound loud and choppy sometime. It was how she said it with negative connotations. By this time I was like go fuck yourself but I had small children to think about. In the future maybe this young lady can understand trying to get service on during the holiday season is stressful enough this is another bill on top of everything else and people don't need stink attitudes to go with it. read more

The plumber gave me an estimate of $500 to install a new dishwasher that I had already purchased. For that kind of money I could have bought another dishwasher. I was charged $65 for the privilege of one of their plumbers making the estimate. Dishwasher installation should not be at the mercy of a lazy plumber who has no interest in doing the job. There should be a fixed rate for this kind of work. Just because I live in Main Line does not mean I have lots of money, nor so stupid that I don't recognize when someone is trying to rip me off. read more

Dear God was this expensive!!! $332 for 15 minutes of work to install an $8 valve. INSANELY overpriced. Do not ever use this service unless you enjoy being ripped off. read more

Predatory Professionals- No Heat- I recently called Henderson to replace a thermal coupling on my furnace in a apartment building. The building had no heat and as a result dozens of people were impacted. When the technician arrived, he had absolutely no intent on repairing the thermal coupling, instead all he wanted to do is give me a quote on a new heating system (which was emailed to me within minutes) and my tenants were left to freeze. It cost $95 for my estimate. The next morning another technician replaced the thermal coupling in 1 hour and the heat was on. I've been in the construction industry for 30 years and I have seen contractors like this in the past. Very disappointing! It makes me wonder how many people were leveraged into spending tens of thousands when a $40 part is all they needed. read more

Their service was grossly overpriced. For unclogging a drain and replacing a pop up stopper, they quoted me at triple what another plumbing company offered. They ask you to pay 65 dollars even if you decline the high priced repairs, just for showing up at your door. They also called me asking for the $65 when they hadn't yet returned my $200 deposit on the repair that I declined. I did get my deposit back, but I'm still out the $65 for having them them to walk into my house and give me an overpriced estimate. read more

I called for a minor plumbing issue. The girl on the phone told me the charge is $125/hour, and $69.00 if you don't agree with the estimate. After looking for 5 minutes, the tech quoted me $450 with what would be a 20 minute job. When I asked how much his hourly rate was, he said $250/hour. I told him that was very different than my phone discussion. He left without doing the work. Many of my neighbors also had a MISERABLE experience with Henderson. Avoid this company. read more

Henderson is now charging people $95 for the privilege of letting them charge you for the repair. In other words, they will charge you $95 for nothing, and then also charge you full price for the repair (time and materials). They used to apply the up front "estimate" charge to the cost of the actual work. Absolute scam. read more

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. read more

I called to schedule a routine annual clenaing and to help diagnose a noise coming from one our a.c. lines in our high velocity system. Everything was working well but still a small noise. The closest they could schedule the cleaning was JULY but they sent a tech out the next day to diagnose the nosie. I still do not understand why both couldn't be done the same day. The tech could not figure out the noise and my husband paid $65 and was told if the noise happens again call and we will come out (for another $65). On top of that he claimed they would not clean the system until we had our attic floor redone in planks. We currently have boards in most of the space and it's perfectly fine to walk around up there. Pissed off we paid $65 for just the truck to show up, I called and canceled our scheduled maintenance and found another company. And guess what, they were able to come out the next day, diagnosed the noise which was something very simple as a sticker stuck in the system, AND cleaned our unit all for $125. Henderson is a total ripoff. We would have paid more in just having a 2nd service call to determine the nosie. Do yourself a favor and call a smaller, local company. read more

10/3/19 - true to form the company again promised one thing and did another. Following my original review the company noted they would reach out shortly given they "take my concerns seriously". They did not reach out. They do not care, now that they're paid. Over promise + under deliver = a very bad experience for me and other customers. Just be honest and do what you promise. read more
