I only use Henderson. They always answer their phone, are available for emergencies, and are extremely clean and knowledgeable. They do not take shortcuts and do the job right.
I had routine heating service and A/C repair. The technician was professional and punctual. He completed the work in a timely manner and explained the A/C issue.
Outstanding service, on time, knowledgeable, friendly, and reliable. Love their crew, cleanliness, and responsiveness—A+.
Great company from the time you call until the service person finishes the job. I have recommended them to family, and they as well have had great service.
Always on time and thoroughly professional. Best service I've had in a long time.
From the estimate to the completion of work and follow up, everything was polite and professional, including the office staff.
Quality service, large service area. Excellent follow up after services have been completed.
They were prompt and knew what to do immediately. They had to replace a part in our heating system.
William Henderson always provides great service. Never a complaint.
The first technician who did the bulk of our work was a top notch, extremely knowledgeable professional. He receives all A+ ratings. A part was back-ordered, however, and the technician who came the second day required some oversight to finish the job correctly. Overall, the job was done as necessary.
