I like that they're very clean. They're very particular in the house. There's one guy that we've had a couple of times, and he's extremely knowledgeable. He can do what needs to be done and nothing extra. We have our maintenance program with them, so they come out and service our air conditioner and heating system. They do the heating system in the winter and the air conditioning in the summer. We've also had them do some additional plumbing. So far, everything is good—I haven't had any problems with anything that they've done. An A grade is fine for them.
The people from Wm. Henderson are prompt, efficient, and clean. Everything that they promised was delivered. We had a new heating unit and air conditioner put in. We chose them because we've used them in the past for other work. I'd give them an A.
Wm. Henderson did something for our air conditioning or furnace a while ago. They did what they told us they would do, and they were friendly and punctual. Our air conditioning was not coming on or something like that. I'll give them an A.
They were here when they said they were coming, they did their job, and it was fine. I had no problem at all. My air conditioner wasn't working, and he fixed it for me. I would say they're an A.
They did a great job. They came out immediately, and I liked their attention to service. We had to replace the heating and air conditioning unit in our house, and they were very quick in accommodating that. Since then, they have done maintenance once. They deserve an A.
I think they have good customer service. They installed our air conditioning system for the whole house. They did the initial installation and annual maintenance, and they also did some sewer backup work, so we've used them for a couple of plumbing and heating jobs. It was a good experience with them every time. I would give them an A.
Wm. Henderson did a thorough job. They did plumbing and heating. They came out several times. They get an A grade.
Wm. Henderson was very nice. They're very good, and they did very well. We're very pleased. They did a lot of work for us.
They did some work for me. They were easy to use and pretty straightforward. We had a problem with the air conditioning unit, and they came and fixed it, drained it, and got it up and running. I'd give them an A.
We were in need of a repair, and they were local. That was the first time I had ever used them. An A grade sounds good for them.
