Cooling Tower Assessments,
Maintenance, Replacements and Repairs
Cooling towers are a cost-effective and efficient way to remove heat from industrial processes and HVAC systems—including those used in manufacturing, food processing plants, power generation, and oil refineries. These systems use evaporative cooling to reduce water temperature, playing a critical role in facility operation.
However, cooling towers require regular service and maintenance to prevent scale buildup, ensure water quality, and protect your HVAC system from premature wear. Poor maintenance can lead to equipment damage, performance decline, and costly unplanned downtime.
Hoffman Mechanical Solutions is proud to be a certified Evapco Factory-Authorized Mr. Goodtower® Service Center, providing professional support for all makes and models of evaporative cooling equipment.
-
Maintenance & OEM Replacement Parts: Our certified HVAC technicians and engineers perform detailed cooling tower assessments and provide recommendations aligned with OEM-recommended maintenance and parts replacement schedules. Proper maintenance extends equipment life, boosts performance, and reduces emergency repairs.
​
-
Cooling Tower Training Programs: We train your facilities and maintenance staff on proper cooling tower care to ensure efficient operation and longer service life.
​
-
Free Unit Inspections for All Brands: Schedule your free cooling tower inspection today—our team evaluates equipment across all manufacturers to identify issues before they become problems.
​
-
Cooling Tower Upgrades & Replacement Units: Whether you're planning a full cooling tower replacement or looking to upgrade for process efficiency, we assess your system and recommend the best solutions based on application-specific needs.
To ensure peak cooling tower performance and reliability, HMS offers free inspections as part of the Mr. Goodtower service program. Combined with regular HVAC maintenance, these inspections help maximize energy efficiency, improve system longevity, and minimize operational disruptions.

Hydronic Equipment Service: Repairs and Maintenance
Commercial hydronic HVAC systems typically include boilers, pumps, chillers, control valves, and piping, all working together to transport thermal energy throughout a facility. With regular preventive maintenance, many hydronic components can operate efficiently for 20+ years before requiring replacement.
Hoffman Mechanical Solutions brings comprehensive experience in commercial hydronic system repair, diagnostics, and maintenance. Our team services a wide range of HVAC hydronic equipment to ensure long-term performance and minimize costly downtime or emergency repairs.

Connect with us if your boiler is malfunctioning or if you have complete equipment failure. Our expert technicians can assist you with both condensing and non-condensing boilers to get your equipment back to optimal performance as fast as possible.
BOILERS
Regular maintenance for pumps is critical. HMS techs can perform an on-site inspection of your pumps to help identify critical corrective or preventive maintenance to prevent or correct serious problems.
PUMPS
Many applications with chillers generate enormous heat loads which must be removed quickly to prevent damage to other equipment or defects in finished products. Our team can help you with service agreements, equipment repair, or on-site inspections to determine where you might encounter problems. Unplanned chiller downtime is expensive, inconvenient, and can be unnecessary with appropriate preventative maintenance.
CHILLERS
Emergency Backup Trailers
From military facilities to hospitals, K-12 schools, and commercial buildings, unexpected utility outages can cause critical HVAC system disruptions. Hoffman Mechanical Solutions designs and builds custom emergency backup HVAC trailers to help mitigate operational risk and maintain business continuity.
These self-contained, mobile HVAC equipment rooms provide essential services such as temporary heat, hot water, and emergency hydronic support, ensuring uninterrupted operations, protecting assets, and safeguarding building occupants.
In 2024, HMS engineered and delivered nine emergency heating and backup water trailers for Fort Liberty, a U.S. military base near Fayetteville, North Carolina. This high-profile project demonstrated the effectiveness of our mobile HVAC trailer solutions across a variety of sectors.
