Thousands of Happy Customers

Was very happy with the quick response to my call for help. It was a very good experience even though it was a stressful situation. They worked with me and were empathetic to my problem and my limitations. They were very thorough in explaining the situation and what needed to be done, explaining and showing me the problem. Once it was decided what I had to do they were quick to get to work and completed the job in a very timely manner. All in all it was a stressful but good experience

– Susan C.

All Pro was awesome we called and they came the same day when our shower drain was leaking into our downstairs ceiling…..the service person was so nice and was very fast and very professional. The price was very reasonable and affordable. They did an outstanding job and we would recommend this company for all your servicing needs. This is the second time using this company, the first was for our water heater and they replaced it fast and very affordable the same day. They came at around 5 and was here until around 9 fixing not only our leaking shower drain but our water pressure value needed to be replaced. They did both and I do not think we would have gotten a better deal or a nicer person to come and do the repairs. All Pro is definitely the people we will be calling for all our plumbing, heating and air conditioning needs from now on.

– Pamela M.

They came to our rescue on January 8, 2018. we had a clogged toilet that overflowed all the way to the downstairs bathroom it was a horrific scene that day. That is when we decided to call All Pro Plumbing. Talked to a nice lady on the phone gave her our info and told us would call back to ensure us someone would come out to help. Within minutes gave us a response time and told us someone will be there within the hour. Sure enough that is when they showed up and quickly diagnosed the problem, went to work, and unclogged whatever was in there that needed to be unclogged. They were efficient, respectful, and professional. They also checkout out other things to make sure that toilet was working fine before they left. Great customer service!

– Vincent M.

Gary was absolutely amazing today. He was friendly, knowledgeable! It seemed a little pricey but our problem needed to be addressed immediately. Great customer service. I would definitely recommend!

– Danielle O.

I would recommend ALL PRO Plumbing to anyone that is looking for good professional service. They installed a sink and garbage disposal for me and did a great job. Their response time is quick. Always either the same day, or the next day

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!
