Comprehensive Fire Apparatus Repair and Maintenance
Fire trucks and emergency vehicles are more than just heavy machinery—they are the lifeline of your community. When the tones drop, lives depend on the performance of your apparatus. There is no margin for error, and there is no time for mechanical failure.
At Twin Tier Fire & Safety Services, we understand the unique, high-stakes nature of fire and EMS operations. We know that a truck out of service is a gap in your community’s safety net. That is why we offer comprehensive service, repair, and installations for all makes and models of emergency vehicles. Our work is performed by trained technicians who don't just have mechanical knowledge,they understand fire trucks.
We are proud to be your local, devoted emergency apparatus service provider, serving departments across Northeast Pennsylvania and the Southern Tier of New York.

Flexibility is key to our service model. Many maintenance tasks and repairs can be performed right at your station via our Mobile On-Site Maintenance units, saving your volunteers or staff valuable time.
However, some complex repairs require the specialized tools and controlled environment of our heavy-duty facility. When that’s the case, we remove the logistical burden from your shoulders. We handle the transport of your apparatus to and from our shop—free of charge. You shouldn't have to worry about transport issues when you have a truck out of service. (Vehicles must be operational and capable of being driven to our facility. Towing services are not provided or reimbursed.)
OEM Quality and Diagnostic Precision
Our team is equipped to diagnose and repair a vast range of apparatus issues using the latest diagnostic software and tools. We believe in doing the job right the first time, which is why we strictly use OEM fluids, filters, and parts.
Whether it’s a specific Cat oil filter for your engine, a Sutphen park brake valve, or a Toyne magnetic switch, we hunt down and install the correct part for your specific apparatus build. We also stock Interstate batteries to ensure that when you hit the starter, the power is there.

Pump Performance Testing (Draft Commander)
Regular pump testing is critical to ensure your apparatus delivers the required horsepower and correct gallons per minute (GPM) when it matters most. A fully involved structure fire is not the time to discover that the primer is not working or the relief valve is leaking by.
For our maintenance customers, we offer pump performance testing using our Draft Commander. This self-contained, water-conserving unit allows us to test without wasting thousands of gallons of precious water. Testing can be conducted at your location or at our shop to ensure your fire pump’s performance under real-world conditions.
- Protection: We stock suction strainers to replace broken ones immediately, ensuring your pump remains protected from rocks and debris.
- Reporting: Your comprehensive NFPA-compliant pump test results are emailed with the invoice and uploaded to your portal.
