F.E. Moran Mechanical Services | HVAC Service & Maintenance

F.E. Moran Mechanical Services has a robust HVAC service offering from retrofits to rebuilds to preventative maintenance that keeps your systems working optimally.

10-Year Extended Warranty

Newly installed equipment and previously installed equipment have up to a ten-year warranty that includes both parts and labor.  The warranties are customized for each facility’s needs, and can include overtime rates, cranes, helicopters, and other services needed for the facility to ensure that it is fully covered.

All warranties are contingent on F.E. Moran Mechanical Services maintaining the equipment to ensure proper care.

Equipment Installation:  New and Retrofit

F.E. Moran Mechanical Systems can retrofit old equipment to new standards and make it more environmentally friendly.  Old equipment can meet new standards and energy codes with a few tweaks. 

A boiler can go from 80% efficiency to over 90% efficiency. 

Our customers can enjoy a higher efficiency system and ComEd, Nicor, and other utility companies will provide rebates.

Equipment Tear-down and Rebuilds

Older equipment occasionally had rooms built around it, and it is nearly impossible to remove the equipment at a reasonable cost.  In these instances, F.E. Moran Mechanical Systems keeps the shell of the equipment but replaces the internal components to extend the life of the equipment.  MMS technicians are experts in tear-down and rebuilds of chillers and AHUs. 

During a chiller tear-down, motors, transmissions, and internals are inspected, and internal gaskets and bearings are replaced.  This keeps the chiller well-maintained and extends its life.  Equipment tear-downs are high-risk and should only be done by professionals who are skilled in this type of service.   

Maintenance Agreements

Keep your HVAC systems running at top capacity with full-service, comprehensive maintenance agreements.  With annual maintenance agreements, you can reduce equipment failures, save money and energy, extend the life of the equipment, and reduce the cost of training and tools.
