Hannon Heating & Air Conditioning handles heating and cooling for offices, restaurants, retail spaces, and property managers in Bellingham, MA and across MetroWest: service, repair, equipment replacement, and preventive maintenance contracts. Paul runs the commercial work with the same crew and the same straight answers as the residential side, and every job is quoted before work begins. We take commercial calls in Milford, Franklin, and Medway as well as Bellingham.

Commercial Preventive Maintenance Contracts

Commercial customers can put us on contract — the one place we offer them. A maintenance agreement means scheduled visits on your calendar (heating checked before winter, cooling before summer), priority response when something quits during business hours, and a documented service record for every visit, which matters for warranty claims, insurance, and landlord files. A restaurant or a retail floor can't ride out a dead system the way a house can wait a day; the contract exists so you never have to find out how long you'd last.

Tenant Build-Outs & Retrofits

When a tenant fit-out needs HVAC, we handle that side: added zones for a reconfigured floor plan, new distribution runs for the space, and replacement of the tired rooftop units and split systems that came with the building. We coordinate directly with your GC, pull the permits, and keep the mechanical work off your critical path where we can. You get one point of contact who was actually on the job, and a written quote before anything is ordered.

Why Light Commercial Owners Call Us

The owner runs the calls. When Paul quotes a commercial job, the person who priced it is the person who shows up, and the number holds. We keep the scope honest too: offices, restaurants, retail, and small commercial buildings running rooftop units, split systems, and standard commercial boilers are our size of work. If your property needs a high-rise central plant crew, we'll say so on the first call instead of learning it on your roof. To talk through a property, call (508) 282-1000.

Frequently Asked Questions

Do you offer maintenance contracts for commercial properties?
Yes — commercial properties are where our service contracts live. A contract covers scheduled preventive visits before each season, priority response for breakdowns, and written documentation of every visit for your records. Terms are set per property, based on the equipment on site.
What size commercial work do you take on?
Light commercial: offices, restaurants, retail spaces, and small buildings running package rooftop units, split systems, and standard commercial boilers. We're honest about the ceiling — a large central plant or high-rise system needs a bigger crew than ours, and we'll tell you that up front.
Can you handle the HVAC side of a tenant fit-out?
Yes. We do added zones, ductwork changes, new equipment, and replacements for tenant build-outs, and we coordinate directly with your GC on schedule and inspections. Send the mechanical drawings or a walkthrough date through our contact page and we'll quote the scope.
Who actually shows up for a commercial call?
Paul, with the same crew that runs the residential side. The person who priced the job is the person who does it, and the number holds. We pull the permits ourselves, and on build-outs we coordinate directly with your GC on schedule and inspections.
