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!

Electrical Services for Your Commercial Property

Our commercial electricians are ready and waiting to help out around your commercial property in Ontario, Alta Loma, Rancho Cucamonga, and other parts of San Bernardino County. Thanks to our extensive industry experience and fully-stocked company vehicles, we are capable of handling most any electrical service job you can imagine. We know that your business is depending on us to get the job done right the first time and on time, too. You’ll notice our genuine sense of urgency – without sacrificing on safety – in everything we do.

Give us a call at (909) 253-0664 if you need assistance with the following and more:

  • Electrical repairsAn electrical fault can be downright dangerous, as it may pose a fire hazard each time a connected electrical component or outlet is used. For electrical repairs done safely and quickly, you’ll want no one but our commercial electricians!
  • Lighting installationYou can spruce up your business with some new lighting and fixtures throughout it. We like to work with homeowners and business owners alike to come up with lighting installation projects, should you need help deciding where to install new components to best light your office or storefront.
  • Electrical wiringThe wiring running throughout your commercial property has a huge responsibility, and it requires a lot of attention. From rewiring and wiring repairs to new wiring installation, we are capable of handling it all. Be sure to get us on the phone fast if your commercial property has not had any wiring work since the 70s, when unsafe aluminum wiring was quite common.
  • Breaker and fuse box workPerhaps the most complex components of your electrical system are breakers and fuse boxes. The circuit breaker mitigates power flow to protect your entire property from surges, and fuse boxes distribute the correct amount of power to different circuits or areas within your commercial property. If either one is acting up – or you are just getting seemingly unpredictable electrical-related issues – then let lend a hand, inspect these components, and recommend solutions as needed.

Would you like to speak with a San Bernardino County commercial electrician about the electrical issues or projects for your property? Call (909) 253-0664 or contact us online to book a service!
