HVAC Installation and Replacement for Municipal Buildings
Municipal HVAC projects often begin with equipment that has become unreliable, inefficient, expensive to repair, or unable to maintain acceptable building conditions. Replacement may also be required as part of a facility renovation, department expansion, energy-efficiency initiative, accessibility project, or long-term capital improvement plan.
The objective is not simply to remove one unit and install another. The replacement equipment must fit the building, connect correctly to existing systems, perform as intended, meet applicable requirements, and remain accessible for future maintenance.
DePue supports municipal HVAC projects from the initial equipment review through removal, installation, startup, and turnover. Because DePue also provides piping, sheet metal fabrication, equipment setting, and project coordination, many of the supporting mechanical requirements can remain under one coordinated team.
Depending on the facility and system, the work may include:
- Rooftop HVAC units
- Packaged heating and cooling equipment
- Air-handling units
- Make-up air units
- Unit heaters
- Commercial boilers
- Hydronic heating equipment
- Chillers
- Cooling towers
- Pumps and heat exchangers
- Exhaust and ventilation systems
- Commercial ductwork
- Custom sheet metal transitions
- Natural gas piping
- Condensate piping
- Hot-water and chilled-water piping
- Equipment supports and bases

Municipal Rooftop Unit Replacement
Rooftop HVAC units are common in village halls, police stations, fire stations, public works buildings, libraries, recreation facilities, and other municipal properties. Replacing them requires more than selecting a comparable model and scheduling a crane.
DePue can coordinate the mechanical portion of a municipal rooftop unit replacement from field verification through final startup. For municipalities with multiple buildings or several aging rooftop units, DePue can also help organize replacements into phases based on equipment condition, operational importance, facility schedules, and available capital funding.
Existing roof curbs, duct openings, structural conditions, gas piping, electrical service, controls, condensate drainage, access, clearances, roofing conditions, and equipment dimensions must all be verified before installation.
Typical support may include:
- Existing equipment assessment
- Replacement-equipment planning
- Field measurements
- Equipment procurement coordination
- Removal and disposal
- Crane and rigging coordination
- Roof curb review
- Curb adapters or modifications
- Custom duct transitions
- Sheet metal fabrication
- Natural gas piping

Boiler, Chiller, Cooling Tower, and Central Equipment Projects
Boilers, chillers, cooling towers, pumps, air-handling systems, and other central equipment can affect more than building temperature. These systems influence facility reliability, maintenance workload, freeze protection, indoor conditions, energy use, and whether a building can remain occupied.
DePue supports planned replacement and mechanical-room projects involving central equipment where multiple systems must be coordinated together. When a municipality needs one point of coordination, DePue can also manage qualifying supporting scopes such as controls, electrical work, roofing, structural steel, concrete, demolition, crane service, and restoration.
For applicable boiler and pressure-piping work, DePue also provides boiler installation and code-welding services.
Central equipment projects frequently involve several connected scopes. Piping may need to be replaced or rerouted. Pumps and valves may need modification. Equipment may require new bases or structural supports. Electrical service, controls, ventilation, rigging, demolition, roofing, and restoration may also be required.

Capital Planning and Phased Equipment Replacement
Municipalities often manage several buildings with mechanical equipment of different ages, manufacturers, conditions, and operating requirements. Replacing every aging system at once may not be practical, but waiting for each unit to fail can create emergency costs, rushed purchasing decisions, and avoidable disruption.
DePue can help municipal facility teams assess existing equipment and organize replacement priorities. A phased equipment plan can help identify which systems present the greatest operational risk, prepare more accurate capital requests, coordinate replacements across multiple facilities, and reduce unplanned emergency work.
The review may also identify equipment that can remain in service through targeted repairs or preventive maintenance, allowing available funding to be directed toward higher-risk systems.
Replacement priorities may be organized around:
- Equipment age and condition
- Repair history
- Frequency of service calls
- Parts availability
- Reliability problems
- Occupant complaints
- Operational importance
- Energy performance
- Expected remaining service life
- Access and installation difficulty
- Seasonal requirements
- Facility schedules
- Available capital funding
- Opportunities to group related work
