Thousands of Happy Customers

This is a great company. I had a water heater installed and never had a better service person. He was informative and did a wonderful job. Very prompt and efficient.


I received an email from All Pro saying my water heater was due for an annual maintenance. I gave them a call thinking I would be scheduling an appointment for a week or two in the future. To my surprise they said they would send a technician right away. Wow, that’s service! He arrived and introduced himself and told me about what he planned to do. It was a pleasure working with him. He was friendly, polite, and terrific with dogs. It was a hot day, a very hot day, and my water heater is in the garage. I felt rather guilty about that but he didn’t complain. He took care of everything and left the area neat and tidy. He even helped me move a couple of the heavier boxes back into place. I’ve used All-Pro for all my plumbing work. They are always timely, helpful and get the job done right.

Thank you for the prompt and professional service. When our A/C stopped working yesterday, I assumed that the 17-year-old compressor was just going to need to be replaced. I looked at reviews for several companies and called some of them. The smaller companies had a wait of a week or more, and the bigger companies seemed to be money-hungry. The reviews online for most companies were scary….horror stories of $25,000 quotes, etc. Since it’s August, I was out of options, resigned to the fact that thousands of dollars would be spent, and in a time crunch, so I called two of the bigger ones, including All-Pro. Since your company was able to send someone the next day, I went with it. (Well, ok, I had another company scheduled in the afternoon so I could compare the two ridiculous quotes…..I did call them and politely cancel..). Your very professional dispatchers called us this morning to let us know that they could send someone even earlier. Yay! The tech was very professional, polite, and friendly. He gave us several options, all of which were far less expensive than I had feared. He was very patient as we asked a million questions. He got our old system back up and running and let us know some things to keep an eye on. Bottom line, less than 24 hours passed between the time I discovered the A/C was broken until the time it was fixed, and at a reasonable price. Thanks ALL-PRO.

-Lisa L.

I was very happy with the job they did! I had been waiting on a plumber from another company all day, just to be called at 4 pm saying they wouldn’t be able to make it. I called All Pro and they said they could send someone over between 5-7, I was so relieved. He showed up around 530, diagnosed the problem, gave me the price and as soon as I agreed, he got to work right away! He was quick and fixed our clogged drain and cleaned up afterward. It was exactly the service and care I was looking for!
