WM Henderson Heating, Cooling, Plumbing, & Electrical Inc.

Steve and David did a great job diagnosing and clearing out our backed up kitchen drain. Very pleased with their work and would not hesitate to have them here for any other problems that might arise.

Our technician, James, was fantastic. He listened to our concerns, was clear in communicating our options and recommendations, and even though it had been several years, even remembered being at our home previously and our animals. James did a thorough inspection, and when we decided to move forward with additional work, he did an excellent job. 10/10 for Henderson, because of James!

Such wonderful service with great professionals. Our furnace died on a weekend and we needed help quickly. They responded and took care of us timely and professionally. Would NEVER use anyone else!!! Great prices too!!! THANK YOU!

Long story short, My daughter decided to flush two priceless pieces of jewelry down the toilet. My wife and I didn’t realize that she had done this until two days later. We knew the chances of finding one let alone both pieces were slim if at all. Thanks to Wm. Henderson and their magician of a Plumber Dan, he was able to retrieve BOTH pieces… Dan arrived on time, was extremely Professional and was fully equipped to handle the task at hand. I can’t thank Wm. Henderson and their team enough for having such a skilled and knowledgeable tech on hand. Thanks to you all we have the Jewlery back!

Despite several unanticipated issues including defective parts, Joe stayed with the challenge even though it required returning a second day. Excellent service.

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.

the entire process took less time than I thought it would. I was able to pick up my lunch while technician went to pick up the replacement water heater replacement. The process was "seamless" and my questions were answered . I also found out he has a rescue dog as do I.

The HVAC had sprung a leak. Joe and Eric both worked on the system to detect and then fix the problem They are very good technicians and a pleasure to have working at one's home. Trust worthy and knowledgeable.

My technician Gabriel was amazing, He was professional, knowledgeable, courteous and compassionate. I will certainly recommend this company to everyone. One month after my heater repair I needed electrical work and Wm Henderson who has partnered with Farryn Electric came through. My electrican Kevin and his crew were excellent. They not only did a stellar job repairing the issue they clean up afterwards. They went above and beyond to make sure everything was safe and in perfect working order. Kevin even brought a generator with him so I could continue to work online while they did the repair. Awesome

My job was to have our thermostats upgraded throughout the house. I expected that we would need a tech to come out one time to diagnose, and then one more time to perform the upgrades. Here is a summary of my actual experience:

1st Trip:
Tech comes and diagnoses the thermostats. He informs us that we only have a two-wire system, so we should buy Ecobee thermostats instead of Nest. This was helpful to know, and we were able to save some money by buying the thermostats ourselves. He also suggests we find out if smart thermostats exist for our high-voltage heated baseboards (we found out that only one such product exists, called Mysa). Tech was on-time, friendly, and seemed knowledgeable.

2nd Trip:
Tech arrives after the four-hour arrival window due to previous projects overrunning their schedule. This was a little frustrating as we'd already needed to stay home all day, but it wasn't the end of the world. Please just fix our thermostats! He pokes around for a while and installs Mysa thermostat #1, and Ecobee thermostats #1 and #2. However, he then finds that the hookup for Ecobee #3 has actually had its wires cut, for reasons unknown.

He says he can't finish the job that day and that he'll need to return again at a later time. This was very frustrating to hear, as this should have been discovered during his first trip. But there was nothing we could do about it, so we had to schedule a third workday.

3rd Trip:
The tech arrived within the arrival window, this time with a 2nd tech (who reeked of cigarettes) to assist. They were able to reestablish the hookup to Ecobee #3 fairly quickly. However, they also spent a lot of time and effort trying to wire a fresh hookup to Ecobee #2. They asked my permission to drill a giant hole through the wall to make their wire routing easier, which I roundly declined. Not only would that require patching and painting that I wanted to avoid, but it would also cause significant damage to the >100-year-old brick beneath the drywall.

I countered by pointing out the internet hookup at the base of this same wall and contended that if the Xfinity guy could figure out how to get through the wall without damaging it, so could they. They conceded the point and tried to figure it out, but they said there was a 2x4 in the way and that they couldn't do it. I then realized:

"Wait a minute, why are you even installing a fresh hookup to this thermostat? It already works!"
"The hookup only has 2 wires, and the system won't work in its current wiring configuration."
"Okay, but you told me that the Ecobee would work with only 2 wires. What changed?"
"Oh, well, I guess that's true, but we would have to wire it differently."
"Well then by all means please just wire it differently!"

They ultimately were able to get a fresh 10-wire hookup in this location without damaging the wall beneath. They were "done," stepping outside to write up the work. While outside, I watched the 2nd tech litter his used cigarette butt into the street. We live in a beautiful neighborhood where people really care about keeping the sidewalks, yards, and streets clean, so this was very disappointing to see. I picked it up and threw it away into the trash.

When the 1st tech came back inside to have me sign for all the completed work, I told him that neither of the Mysa thermostats were working. He told me that they would need to be activated by a smartphone app, but fortunately I had come prepared and knew that something was still wrong.

The techs came back in to continue working on the Mysas. They first used a voltmeter to confirm that the hookups were hot (why hadn't they done this before?), and they saw that they were. Then they used the wiring diagram in the manual and realized that they had rigged them up incorrectly. They rectified the issue, and the thermostats booted up right away.

Update:
WMH, I want to thank you for reaching out with a partial credit for the work. While the gesture doesn't undo my negative experience, it was appreciated and a professional/appropriate way to respond. I've bumped my review up by 1 star.
