MAINTENANCE, REPAIRS
& 24-HOUR SERVICE

Regularly scheduled preventive maintenance is a proven strategy for maximizing equipment performance, reducing failure and decreasing the overall cost of equipment ownership. Downtime, lost productivity and discomfort complaints are significantly reduced when equipment is properly maintained. Energy consumption is also kept to a minimum while improving performance and extending the useful life of equipment.

& INSPECTIONS

Fire, smoke, and combination fire/smoke dampers are crucial pieces of equipment used to reduce the spread of fire and smoke throughout a building. As with all fire protection and life safety equipment, fire and smoke dampers must be properly inspected, tested, and maintained to ensure that they will operate when needed.

Cottonwood Screens

COIL & TOWER PROTECTION

Cottonwood screens, also known as air intake screens, are used to protect condenser coils, cooling towers, chiller, and OA louvers from airborne debris that can clog and damage the system. They are designed to be used in high volume, high velocity air movement systems, and have a low impact on airflow and static pressure.
