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!

Why Choose a Boiler System?

Boilers are a popular choice among business owners for a variety of reasons. For one, they’re generally reliable and energy-efficient, running well with few to no problems with very little attention or maintenance. They’re also tremendously effective, providing an abundance of heat wherever it is needed without a huge energy bill at the end of the month.

When you combine that with their ability to also provide your business with a nearly-limitless supply of hot water, it’s easy to see why so many people choose to make the investment in their business and go with a boiler system for their heating.

Boilers enjoy many of the following advantages:

  • Fast heating: a boiler can quickly bring the temperature throughout your facility up, ensuring better comfort faster
  • Greater heating capacity: Whereas forced air systems generally can only heat a smaller space, large boilers can heat massive office buildings or large spaces all from one single unit.
  • Greater control: Boilers can be easily and quickly configured for zone control, allowing those in separate areas of your facility to turn their heating on and off or adjust the temperature independently of other areas.
  • Ditch the water heater: Why heat water twice? Set up your boiler to provide you with hot water and you’ll get the function of two major appliances from one!
  • Superior longevity: Whereas many forced air heating systems generally last around 10 to 15 years, boilers can often go well past 20 years or more before needing replacement.

We encourage all business owners or commercial property managers to consider their current heating system and find out if switching over to a boiler is right for you. If you already have a boiler system, we can provide you with repair, maintenance, leak detection, and boiler replacement in Ontario and San Bernardino—as well as other critical services vital to safe and ongoing operation.

What Are Common Boiler Problems?

Boilers are not immune from problems—they can experience issues that need urgent repairs. At All Pro, getting to you and getting your issue resolved quickly is what we do best. We can service all different types of problems that your boiler may experience, including things like leaking pipes, inconsistent or lukewarm temperatures, broken heating elements, exhaust issues, and everything in between. When it comes to your business, no issue is too large or too small.

Should You Repair or Replace Your Boiler?

If your boiler is showing signs of age or the issue you’re having is serious and will require extensive repairs, you may want to new installation or boiler replacement in Ontario or San Bernardino, CA. However, replacement is not always the best option—sometimes you simply can’t afford it with expenses or you need your system back online as soon as possible. All Pro Plumbing, Heating, Air & Electrical understands and we offer extensive repairs and upkeep services designed to get your system working again and keep it that way!
