Take Control of Facility Maintenance in Three Steps

Every facility is different, so GEM doesn’t take a one-size-fits-all approach. We work with you to create a customized maintenance plan that helps improve reliability, simplify facility management, and support long-term cost control. 

A GEM account manager will review your facilities, equipment, maintenance history, and service needs. This allows us to catalogue your equipment, understand your operation, and identify opportunities to improve reliability, efficiency, and long-term performance.

Based on your organization’s unique requirements, we’ll develop a preventative maintenance program that fits your equipment and priorities. Your proposal will outline recommended services, inspection schedules, included testing, and available benefits.

Once your plan is in place, GEM handles the scheduling, maintenance, inspections, and reporting needed to keep your systems operating at their best. You’ll also have a dedicated account manager and access to preferred pricing and priority service whenever you need support.

The 2 service men were on time, assessed the problem, diagnosed the issue, came up with a plan and offered several solutions for fixing our mini split. They took pictures, tried clearing out mice debris , attempted to get the outside machine to work ( apex 2 hours) Alas a no go, so we decided to scrap it and go with baseboard heater for the room over the garage. Up front information and pricing , no nonsense. Affable techs and so far great service.

I was thoroughly impressed with the superb HVAC maintenance service I received from David Santiago and trainee, Kevin today! Before David and Kevin arrived I was very disappointed with having had my original service date rescheduled to what I thought were spurious reasons? In fact David and Kevin arrived after the designated rescheduled date and time today. GEM's communication was excellent throughout and their people seemed genuine and concerned. When David and Kevin arrived it turned the whole situation around. They could not have been more professional and knowledgable! I am now firmly committed to GEM and their Home Comfort maintenance program.

We just had our heating system replaced. We went from forced hot water system to a central heating and air conditioning system done by GEM plumbing and heating company We had Omar and Michael work in our home for 5 days they installed all the ductwork, the furnace and the condenser. These guys were very professional, kind, clean and informative throughout the whole install every day they explaind what they did and what is the expectation for the next day. Today was the last day they walked me through the whole system, how to change the filter how to operate the new thermostat and what to look for when things are not working properly. I say thank you to the whole team from planing to done, all went great to expectations

One Agreement. Five Essential Trades.

Most commercial maintenance programs focus on a single trade. For many facilities, that means managing multiple service providers, contracts, and points of contact to maintain the systems that keep buildings running safely and efficiently. 

GEM’s preventative maintenance plans bring multiple building services together under one agreement, giving your team a single point of contact for these critical facility systems:

Instead of coordinating multiple vendors, invoices, and schedules, critical equipment maintenance is managed by one experienced partner. For organizations with multiple locations or regional portfolios, this creates significant operational efficiencies and greater consistency across properties.

Dedicated Account Management and Ongoing Support

When you partner with GEM, you gain a dedicated account manager focused on helping your facilities operate more efficiently.

Your account manager serves as a single point of contact, helping coordinate services, answer questions, review recommendations, and ensure your maintenance program continues to align with your operational goals.

As your facility needs evolve, your account manager is there to provide guidance, facilitate communication between departments, and help prioritize maintenance and repair needs. With a consistent partner who understands your buildings, equipment, and service history, you can spend less time managing vendors and more time focusing on your organization’s day-to-day operations.

Comprehensive Maintenance for Critical Building Systems 

Every commercial facility has unique equipment and maintenance requirements.

GEM builds customized preventative maintenance plans that protect critical equipment and fit your facility’s specific needs and goals.

HVAC systems remain the foundation of most commercial maintenance programs because heating and cooling equipment often represents one of the largest operational investments within a facility. Cooling maintenance is completed before peak air conditioning season, while heating maintenance is scheduled before colder weather arrives. This proactive approach helps identify potential issues before they become costly emergency repairs.

During each visit, GEM technicians perform a comprehensive inspection of your equipment, including filter changes, startup procedures, performance testing, and operational checks. Regular maintenance helps improve system efficiency, reduce the likelihood of unexpected breakdowns, extend equipment life, and support a more comfortable environment for occupants year-round.

Drainage issues develop out of sight, which makes them difficult to detect until they cause backups, property damage, or operational disruptions. To identify potential problems early, GEM includes a main drain camera line inspection as part of our commercial preventative maintenance plans.

Using specialized camera equipment, our technicians inspect the condition of your main drain line and look for signs of blockages, buildup, root intrusion, or deterioration. This proactive assessment provides valuable visibility into the health of your drainage system and helps facilities address concerns before they become costly emergencies.

Backflow prevention devices protect potable water supplies from contamination and are subject to annual testing requirements. Annual testing keeps your facility compliant.

GEM includes annual testing for up to three backflow devices as part of your maintenance agreement. Our team performs the required testing, documents the results, and helps ensure your facility remains compliant while reducing the administrative burden on your staff.

Electrical failures can create serious safety risks, costly downtime, and unexpected repairs. Infrared inspections provide a non-invasive way to identify developing problems before they impact operations.

Our plans include an infrared inspection of one electrical panel in accordance with NFPA 70B best practices. Thermal imaging can help identify overheating components, loose connections, and other developing issues before they result in equipment failure. Many insurance carriers view infrared electrical inspections as a proactive risk management measure that can help support facility reliability and loss prevention efforts.

Fire protection systems are critical to life safety, regulatory compliance, and business continuity. Routine inspections help ensure these systems are functioning properly and ready to respond when needed while supporting the requirements necessary to keep your facility operational.

As part of our comprehensive maintenance approach, GEM can incorporate fire sprinkler and fire protection inspections into your maintenance program. Regular testing and evaluations identify deficiencies, maintain compliance, and provide facility teams with greater confidence that their fire protection systems are operating as intended.

Priority Service and Preferred Pricing

When issues arise, response time matters. Commercial preventative maintenance customers receive benefits that go beyond scheduled maintenance, including preferred pricing, priority scheduling, fast access to service resources, and dedicated account support.

These advantages help ensure your organization receives timely assistance when critical building systems require attention.

Actionable Reporting That Helps You Plan Strategically

One of the most valuable components of a GEM commercial maintenance agreement is the reporting process. Every facility receives organized documentation that helps maintenance teams and decision-makers understand the current condition of critical systems.

We catalog equipment information, including:

  • Equipment photographs
  • Model numbers
  • Serial numbers
  • Asset information
  • Service history

In addition, inspection reports include a simple red, yellow, and green reporting format that helps prioritize maintenance needs. This approach gives facility managers clear visibility into:

  • Immediate concerns
  • Emerging issues
  • Long-term capital planning opportunities
  • Recommended corrective actions

Instead of reacting to unexpected failures, you can make informed decisions based on real facility da

Reduce Unexpected Expenses and Protect Your Budget 

Unexpected equipment failures can create significant financial strain, forcing organizations to divert funds toward emergency repairs and unplanned replacements.

A proactive maintenance strategy helps reduce surprises by identifying potential issues early, allowing facilities to address them before they become major expenses.

Emergency service calls are often more disruptive and expensive than scheduled maintenance. Through routine inspections, testing, and preventative service, GEM helps uncover developing problems before they lead to costly breakdowns, helping facilities avoid unexpected repair expenses and operational interruptions.

Detailed inspections and condition reporting provide valuable insight into the health of critical building systems. With a clearer understanding of upcoming maintenance needs and potential capital expenditures, facility teams and financial decision-makers can make more informed budgeting decisions and plan for future investments with greater confidence.

Commercial HVAC, plumbing, electrical, and fire protection systems represent major investments. Regular maintenance helps these systems operate more efficiently and can extend their useful life, allowing organizations to maximize the value of existing assets and potentially delay costly equipment replacements.
