Boiler, RTU's & Hydronic Heating Services in Windsor
Whether you need help with an existing boiler, a commercial RTU, or an in-floor heating system, M&M Global will evaluate the equipment and explain the available options clearly.
Boiler Services in Windsor and Essex County
Boilers provide dependable heating in many homes, commercial buildings, multi-unit properties, and industrial facilities. Instead of distributing heated air through ductwork, most boiler systems heat water and circulate it through radiators, baseboard units, fan coils, or in-floor piping.
Because a boiler works as part of a larger system, the source of a heating problem is not always the boiler itself. Pumps, controls, valves, piping, thermostats, expansion components, and heat-distribution equipment can all affect performance.

M&M Global provides professional boiler service in Windsor for residential and commercial properties. Our technicians assess the boiler and relevant connected components before recommending a repair, replacement, or maintenance plan.

Commercial Rooftop Unit Services
Rooftop units, commonly called RTUs, combine heating, cooling, ventilation, and airflow components within packaged equipment installed on the roof of a commercial building.

These systems are frequently used in retail spaces, offices, restaurants, warehouses, multi-unit buildings, and other commercial facilities. Because an RTU may serve a large or heavily occupied area, performance problems can quickly affect employee comfort, customer experience, tenants, equipment, and day-to-day operations.
M&M Global provides commercial rooftop HVAC service in Windsor and Essex County, including RTU troubleshooting, repair, replacement, installation, and scheduled maintenance.
Signs that a rooftop unit may need service include:
- The unit will not start
- The building is not heating or cooling properly
- Airflow has become weak or inconsistent
- Different areas of the property have uneven temperatures
- The equipment starts and stops unusually often
- Occupants notice unusual sounds or odours
- The thermostat or control system is not responding as expected
- Water or condensation appears where it should not
- The system runs continuously without reaching the set temperature
- Utility use has increased unexpectedly
- The RTU requires increasingly frequent service
- Heating or cooling performance changes between zones
Our technicians inspect the relevant equipment and controls to identify the likely source of the problem. Once the assessment is complete, we explain the findings and recommended work before proceeding.
Hydronic Heating Services
Hydronic heating uses heated water to transfer warmth through a building. Depending on the property, the heat may be distributed through radiators, baseboards, fan coils, or tubing installed beneath a floor.
These systems can provide comfortable, even heating when they are designed and operating properly. However, hydronic performance depends on more than the heat source. Pumps, piping, valves, manifolds, controls, thermostats, zoning, and water circulation all contribute to the result.
M&M Global provides hydronic heating installation, repair, and maintenance for residential and commercial properties throughout Windsor and Essex County.
In-Floor and Radiant Heating
In-floor heating distributes warmth through tubing installed beneath or within the floor. Rather than relying entirely on heated air, the floor becomes part of the building’s heat-delivery system.
Radiant in-floor heating may be used in:
- New homes and custom builds
- Home additions and renovations
- Basements
- Bathrooms and living areas
- Garages and workshops
- Commercial buildings
- Warehouses and industrial spaces
- Other properties suited to hydronic heating

The effectiveness of an in-floor system depends on appropriate system design, zoning, controls, water temperature, circulation, and coordination with the flooring and building construction.
M&M Global can assist with new installations, existing-system concerns, mechanical-room components, pumps, manifolds, controls, and other connected hydronic equipment.

Commercial RTU Maintenance
Boilers, RTUs, and hydronic systems benefit from scheduled attention, particularly before the season when the equipment will be placed under its heaviest workload.
Maintenance can help:
- Identify visible wear and developing concerns
- Reduce avoidable performance problems
- Support more consistent heating and cooling
- Improve repair and replacement planning
- Document equipment condition over time
- Prepare systems for seasonal operation
- Give property managers a clearer view of mechanical priorities
Maintenance cannot guarantee that equipment will never fail, but it can help reduce surprises and support more informed decisions. Maintenance findings can also help commercial clients plan repairs and equipment replacements before an aging unit creates an operational emergency.
