Cooling Tower Assessments,
Maintenance, Replacements and Repairs

Cooling towers can be an extremely beneficial and relatively inexpensive way to rid industrial processes of heat, including HVAC system heat, food processing plants, oil refineries, power plants and more. These towers use evaporative cooling to reduce the temperature of circulated water. Cooling towers must be strictly maintained and serviced to remove scale deposits, keep water clean, and protect your equipment. 


Evapco’s Mr. GoodTower program is a comprehensive parts and service program for all brands of existing evaporative cooling equipment. Hoffman Mechanical Solutions is an Evapco Factory Authorized Mr. Goodtower Service Center that provides the following services:


  • Maintenance, service and replacement parts: A cooling tower is often only as good as the system it runs in. Our technicians and engineers can review your complete system and make recommendations on OEM-recommended maintenance and parts replacement schedules. Keeping your cooling tower properly maintained and serviced can not only extend the life of the cooling tower itself, but it can also improve system performance overall and reduce unexpected repairs and, potentially, eliminate unplanned downtime.

  • Training programs: Let our technicians train your facilities and maintenance teams to effectively perform regular maintenance for your cooling towers to keep your system running efficiently.

  • Unit inspections: We offer free cooling tower inspections on every brand of cooling tower. Schedule your cooling tower inspection with us today.

  • Equipment upgrades and replacement units: Connect with us when it’s time to either replace your unit or upgrade your equipment dependent on process needs.  Our team can objectively assess your application needs and make recommendations based on your current system and equipment.


To ensure your cooling tower’s optimum performance and trouble-free operation, our Mr. Goodtower program offers a free cooling tower inspection. This inspection, combined with regular service and maintenance, will ensure your equipment’s peak efficiency and long service life.

Hydronic Systems

Hydronic Equipment Service: Repairs and Maintenance

Commercial hydronic systems usually include pumps, boilers, chillers, piping, control valves and more. The water in these hydronic systems transports energy from one area to another. With proper maintenance, some hydronic equipment can last up to 20 years or more before needing to be replaced. 


Hoffman Mechanical Solutions has comprehensive service experience on a variety of equipment.

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.

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.

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.
