WM Henderson

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.

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.

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.....

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.

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.

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.

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.
