A New Chapter Begins: Guardian Plumbers + American Plumbing

Ontario homeowners have trusted both Guardian Plumbers and American Plumbing, Heating, Air & Electrical for years. Today, we’re proud to share something important:

Guardian Plumbers has officially merged with American Plumbing, Heating, Air & Electrical.

This isn’t a corporate shuffle or a quiet name change; it’s a thoughtful step forward. Two service-driven teams are coming together under one mission: to care for homeowners in Ontario, CA with skill, honesty, and respect.

For our team at Guardian Plumbers, this expansion simply means we can serve you more completely. Plumbing, heating, cooling, and indoor comfort: now all under one trusted name.

What the Merger Means for You

When companies join forces, the first question homeowners ask is simple:

“What changes for me?”

Here’s the clear answer.

Expanded HVAC Services Now Available in Ontario

Guardian Plumbers now proudly offers full HVAC services, including:

  • Air conditioning repair and installation
  • Furnace repair and replacement
  • Seasonal HVAC maintenance
  • System diagnostics and performance evaluations

If your AC struggles during a July heat wave or your furnace won’t kick on during a cold January morning, you now have one team to call.

A Seamless Transition for American Plumbing Customers

If you were a customer of American Plumbing, Heating, Air & Electrical, we want to speak directly to you.

  • Your service history matters.
  • Your warranties matter.
  • Your comfort matters.

This merger does not erase your relationship; it strengthens it.

You’ll now be served under the Guardian Plumbers name with expanded support and resources. We’re committed to honoring existing service agreements and maintaining continuity wherever possible.

Why Homeowners Will Benefit

We live and work in the same communities we serve. That shapes how we approach this merger.

This isn’t about growth for growth’s sake; it’s about better serving local families.

California’s Climate Demands Reliable HVAC Care

Anyone who has spent a summer in Southern California knows how quickly temperatures rise. An aging air conditioner doesn’t wait for a convenient time to fail.

A system that runs constantly without maintenance can:

  • Lose efficiency
  • Drive up energy bills
  • Strain internal components
  • Break down at the worst possible moment

Routine HVAC maintenance and timely repairs aren’t optional; they’re part of responsible homeownership.

By bringing HVAC services fully under the Guardian Plumbers umbrella, we’re making it easier for homeowners to stay ahead of costly breakdowns.

You don’t need multiple appointments with different companies. You need one team that sees the whole picture.

Our Focus Hasn’t Changed

Guardian Plumbers was built on core values:

  • Integrity
  • Loyalty
  • Positive attitude
  • Self-development
  • Teamwork

Those values don’t change just because our services expand.

When we step into your home for an HVAC call, you’ll receive:

  • Clear explanations of what we find
  • Options, not pressure
  • Upfront pricing
  • Respect for your space
  • Technicians who are trained, background-checked, and professional

We believe customers deserve to make informed decisions. That applies to a sewer line and to a furnace replacement.

Who You’ll See at the Door

Trust matters.

Every Guardian Plumbers technician upholds the same standards across our plumbing and HVAC services:

  • Exceptional Customer Service
  • Unbeatable Prices
  • Satisfaction Guaranteed
  • Certified, Reliable Technicians
  • 7 DAYS A WEEK Availability

We show up prepared, we communicate clearly, and we clean up after ourselves. It’s not complicated: it’s simply how service should be done.

Ready for Reliable HVAC Service?

If your air conditioner is struggling, your furnace needs attention, or you’re simply due for routine maintenance, we’re here.

Thanks to our merger with American Plumbing, Heating, Air & Electrical, Guardian Plumbers now proudly provides HVAC services backed by the same professionalism and integrity that built our plumbing reputation.
