About Us

About Alpha Omega Emergency HVAC | AC- Heating - Gas

Alpha Omega is a family-run plumbing and HVAC company rooted right here in Quincy, and most of our work comes from neighbors telling neighbors. Homeowners across Quincy, Braintree, and Weymouth call Sam and his crew because they show up when they say they will, explain exactly what's wrong before a wrench is turned, and quote a fair price in writing — no surprise add-ons when the job is done. Whether it's a leaking AC line on a humid August afternoon or a boiler that quit during a Nor'easter, we treat every call like it's our own family's home on the line.

South Shore homes keep us on our toes, and we've built our craft around them. The historic triple-deckers in Quincy Point and Dorchester hide generations-old plumbing — galvanized supply lines choked with decades of scale, and cast-iron sewer stacks finally rusting through — and repiping them cleanly takes experience, not guesswork. Up in Weymouth and Milton, hydronic boiler systems need proper freeze protection and smart maintenance before the first hard frost hits. We know these houses because we've been inside hundreds of them.

What you can count on every visit: a technician who arrives inside the promised window, wears floor protection, cleans up after the work, and walks you through exactly what was done and why. That's earned us a 4.3-star rating from 35 Google reviews and customers who call us back for every job — from a clogged kitchen drain to a full central air replacement. Straightforward, transparent, and genuinely good people to have in your home. That's the Alpha Omega way.

Our Capabilities

Expert Craftsmanship & Reliable Solutions

Every service is backed by our licensed technicians and complete warranty.

Emergency Plumbing & Leak Repair

Burst pipes, leaking fixtures, and clogged drains don't wait for business hours — and neither do we. We locate the true source of the leak fast, make a clean, code-compliant repair, and check the surrounding lines so the same problem doesn't resurface next month.

Cast-Iron Stack & Galvanized Repiping

Many of Quincy's older triple-deckers still run on original galvanized supply lines and corroding cast-iron sewer stacks. We replace them with modern PEX and PVC systems — restoring water pressure, ending chronic clogs, and bringing century-old plumbing up to today's code.

Book Service →

Heating, Boilers & Freeze Protection

We service and install gas boilers and hydronic heating systems, with seasonal tune-ups that protect against Massachusetts freeze damage — from glycol charging and zone valve repair to a full boiler replacement sized correctly for your home.

Book Service →

AC Repair & Central Air Installation

From a leaking line set that's draining onto your floor to a tired central air unit past its lifespan, we diagnose it honestly and fix it right — including full system replacements with high-efficiency equipment that cuts summer cooling costs.
