Commercial Heating, Cooling & Plumbing in Weymouth

Why Local Businesses Trust Alvin Hollis

With an A+ rating from the Better Business Bureau and a reputation built over a century and a half, we don't take your trust for granted. We know that every time we enter your place of business, we are representing a five-generation legacy.

Professional Standards & Competent Care

We are fully insured and our technicians are trained to work in active commercial environments. We strive to be as unobtrusive as possible, completing our work with minimal disruption to your staff and clients. We provide clear, down-to-earth communication about what your system needs and what it doesn't, allowing you to make informed decisions about your facility’s budget.

Practical Financial Support

We know that unexpected mechanical failures aren't always in the quarterly budget. To support our local economy, we offer various financing options and payment plans. This allows you to invest in high-quality, long-lasting equipment without compromising your cash flow.

Comprehensive Heating & Cooling Solutions

The comfort of your employees and customers is a direct driver of your success. An HVAC system is a complex network that requires a different level of care than a residential unit. These systems often run 24 hours a day, seven days a week, and are subject to higher occupancy loads and stricter ventilation requirements.

Reliable Heating Oil & Gas Services

Many businesses in our area still rely on traditional heating oil to stay warm through the harsh New England winter. We provide reliable delivery of traditional and sulfur-free heating oil, allowing your boilers to run cleanly and efficiently. Beyond fuel delivery, we manage the maintenance and upgrading of both oil and gas heating systems. If your rooftop unit or basement boiler is showing signs of age, such as inconsistent temperatures or rising fuel costs, we can evaluate the system and provide a practical path forward for an upgrade.

Cooling & Indoor Air Quality

Summer humidity in coastal towns like Quincy can put immense strain on AC systems. We focus on high-efficiency cooling solutions that help lower your monthly utility bills while maintaining a stable environment for sensitive equipment or perishable stock. Furthermore, we look at the health of your air. We install and maintain systems designed to provide clean, green air, reducing allergens, and improving the overall atmosphere of your workplace.

Plumbing & Infrastructure Support

A plumbing failure in a commercial setting is rarely just a "leak." It can lead to health code violations, property damage, and a total halt in production. Whether you are dealing with a restaurant kitchen in Weymouth or a multi-unit residential building in Brockton, we handle the heavy-duty plumbing required to keep things moving.

High-Volume Water Systems

Commercial water heaters and piping systems are built to handle a much higher volume of use than home plumbing. We provide routine inspections and full-scale repiping services to address low water pressure, discolored water, or recurring clogs. We also handle the installation and maintenance of sump pumps and backflow preventers, which are critical for protecting your foundation and the local water supply from contamination.

Preventive Maintenance for Facility Managers

The best way to handle a plumbing emergency is to stop it before it starts. We work with facility managers to create maintenance schedules that include checking valves, testing pressure regulators, and clearing main drain lines. This proactive approach helps you plan for repairs on your own time, rather than reacting to a crisis in the middle of a busy workday.
