Precision Installation Standards

Our installation technicians follow strict manufacturer guidelines on every project. In addition, we adhere to our own rigorous internal installation standards developed through decades of field experience. These standards are designed to maximize system performance, reliability, and longevity.

Every refrigeration installation includes:

• Proper equipment placement and mounting

• Accurate refrigerant piping installation

• Nitrogen pressure testing of all refrigerant piping

• System evacuation to a minimum of 500 microns

• Verification of leak-free, moisture-free refrigerant circuits

This meticulous process ensures a dry, tight, and efficient refrigeration system that delivers years of trouble-free operation. Shortcuts are never taken, because we know that installation quality directly impacts system performance.

Our technicians take pride in their craftsmanship and consistently deliver clean, professional installations that meet or exceed industry standards.

Preventative Commercial Refrigeration Maintenance

Preventative maintenance is one of the most effective ways to reduce operating costs, improve reliability, and extend the life of your refrigeration equipment. National Mechanical Services has been providing commercial preventative maintenance services for over 35 years, helping customers avoid costly emergency repairs and unexpected downtime.

Commercial refrigeration systems operate continuously and under demanding conditions. Without proper maintenance, efficiency drops, components fail prematurely, and energy costs increase. Our customized maintenance programs are designed to keep your systems operating at peak performance.

Lower Utility Bills

Proper maintenance significantly reduces energy consumption. Clean condenser coils, proper refrigerant levels, and well-maintained components allow your refrigeration system to operate efficiently.

Benefits include:

• Reduced electrical consumption

• Lower monthly utility costs

• Improved system performance

• Reduced strain on compressors and motors

Over time, the energy savings alone can offset the cost of routine maintenance.

Healthier, Cleaner Air

Commercial refrigeration systems circulate large volumes of air that can contain dirt, bacteria, and contaminants. Without routine cleaning, these contaminants accumulate and circulate throughout your system.

Regular maintenance includes:

• Coil cleanings

• Removal of dirt and debris

• Inspection of airflow paths

This results in cleaner circulating air, improved sanitation, and better compliance with health and safety standards—especially important for food service and healthcare environments.

Prolonged Equipment Life

A properly maintained refrigeration system lasts significantly longer than a neglected one. Routine inspections help identify small issues before they become major failures.

Preventative maintenance helps:

• Extend equipment lifespan

• Reduce emergency service calls

• Minimize costly component replacements

• Improve system reliability

Many emergency breakdowns are directly related to insufficient maintenance. A proactive approach protects your investment and reduces long-term service costs.
