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.

I was not a service call. It’s just a yearly check up on the air conditioner. I did not meet Thomas personally, but my wife said he was very nice man. you must’ve needed a garden hose for something. I noticed it was moved, but it was wrapped very nicely and put back where where he found it. I appreciate that. overall, we were very pleased with the service. Thank you.

Great company to work with! Good communication, availability and the plumbers who came to pull a gas line were professional. Would definitely use their services again.
We received great service and happy with the results!
Tony and Kevin were great, very professional and very knowledgeable- they listened to what I thought was going on, started there and quickly solved the A/C airflow issue. In this day and age and how expensive everything seems to be it was refreshing that Tony seemed very aware of pricing and as a result of their experience and efficiency make the bill very reasonable
Aaron was knowledgeable and extremely helpful
Technicians Steve Gray and Chase were Outstanding in every detail from presentation to knowledge , expertise and commitment to resolving my problem. I am a very please customer and I just need to say Steve and Chase represent your company extremely well. I will continue to be a very loyal customer. Thank you
Xavier and Mike did an excellent job.
We were very happy with the Service! Jacob and his “understudy” showed a very professional and efficient service. Jacob seem to be very experienced, and knowledgeable, and can think outside of the box. For over 20 years every time we had the boiler serviced, louvre was recommended as a solution for the low air supply.. Jacob saw the unused 4 inch dryer duck which is already in place and with minor modification can provide more air, which I thought was a brilliant idea. Highly recommend this team to anyone!
Nicholas from GEM was very informative and fixed our problems and gave good advice. Thank you!
Generator maintenance. Excellent in all respects.
Douglas is terrific!
Orlando and Marcello are true superstars of your business! Polite, very quick at helping me fix my problem with my Plumbing. The whole process from start to finish was handled beautifully thank you so much for making a stressful situation so much easier!
Excellent work on a variety of household electrical needs. Service techs were professional, friendly, and all work done to high standards!
Excellent service! Gem Plumbing was professional, responsive, and arrived on time. They quickly identified the issue with the roof drain pipe, clearly explained the repair, and completed the work efficiently. The quality of the workmanship was excellent, and everything was left clean when the job was finished. I would definitely recommend them to anyone looking for a reliable plumber.
Excellent service with clear explanation. On time, friendly professional communication. Issues resolved with creativity!
Cory was very knowledgeable and respectful.
The technical aspects of the job he explained so I could understand.
Great all around for a large on-demand heating installation project . Very talented team. Very impressed . Will definitely use GEM in the future
I had a great experience with my recent HVAC appointment. David the technician was punctual, polite, and very thorough while performing the annual maintenance of both our heating and cooling systems.

Efficient professional and quick service excellent!! Thank you Eric
Devontay Vaz and his colleague did an excellent job servicing our scheduled maintenance on our Heating and Cooling Mini Split system which is part of our Maintenance Plan. They took the time to explain the process from start to finish. They also made sure to explain the future unit maintenance after the summer season, which we found VERY helpful. We have been members of Gem Heating and Plumbing for years now. As always, the technicians were polite, professional, and knowledgeable about their work. With life being busy, Gem always call us as a reminder to make these scheduled appointments. Thank you, Gem Plumbing!!
John is great.

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.
