MSC: Ten Reasons Why You Need an Advanced HVAC Service Specialist

Mechanical Service Corporation is the leading diagnostics and service specialist in advanced HVAC, process cooling, and building automation systems in the Northeast and Mid-Atlantic regions.

Unlike the typical HVAC contractor, we are not a plan-and-spec installer with a service department. Rather, MSC specializes in solving complex building system problems. Led by on-staff engineers, our technicians receive continual technical training and are equipped with the latest, most advanced tools and equipment available.


Here are ten indicators that your building needs the services of MSC.

  1. Continual temperature and humidity issues that in-house staff, engineers and HVAC contractors are unable or unequipped to solve.

  2. Repeated compressor failures indicate underlying system problems that must be resolved. If the root cause of the failure is not corrected, subsequent compressors will likely fail as well.

  3. Persistent building automation and control (BAS) problems, such as systems constantly in alarm, inconsistent control, freeze-stat trips, instruments out of calibration, or pumps and fans running erratically, that lead to frequent emergency service calls.

  4. Vibration, noise and resonance issues that, left unaddressed, lead to poor system performance, energy inefficiency, and costly equipment failure.

  5. Advanced testing, adjusting and balancing (TAB) is necessitated when standard TAB is insufficient to address deep-seated, pervasive, or chronic problems in complex or mission-critical systems.

  6. Puzzling HVAC system electrical problems such as repeated starter and contactor failure, unexplained induction issues, CPU failures, voltage spikes and dips, and instrument failure.

  7. Unresolved building or laboratory pressurization and air change issues that can jeopardize critical process and place occupants in harm’s way.

  8. Chiller surge and other central plant problems such as cooling tower malfunction, poor water quality, heat exchanger performance concerns, and issues with control of chilled water valves, coils and distribution.

  9. Problems with variable frequency drives and motor control such as VFD nuisance faults, VFD failure, motor failure, and bearing failure due to stray voltages.

  10. Mission-critical cold rooms, freezers, process cooling, and low-temperature systems are unreliable, cause compliance issues, and constantly need repair.
