OVERHAUL

Comprehensive HVAC System Maintenance

OVERHAUL is the only HVAC acid/moisture eliminator + system enhancer in one tube, designed to stabilize, optimize and revitalize both old and new systems. Acid and moisture are leading contributors to corrosion, electrical breakdown, and premature compressor failure; Overhaul targets both—helping to neutralize acid and remove moisture—so your system runs cleaner, quieter, and longer. Its oil‑return technology improves lubrication at the compressor, while enhanced heat transfer supports better thermal performance across the system. With no sealant in the formula, Overhaul avoids the risks associated with clogging or masking leaks, making it a smart, preventive choice during tune‑ups, retrofits, and overhauls of residential HVAC equipment. Use it to help optimize performance, reduce noise, and protect against future burnouts—all with one convenient, sealant‑free solution.

Key Features and Benefits:

Dual‑action contaminant control: helps eliminate both acid and moisture
Oil‑return enhancer: promotes proper oil return to the compressor for better lubrication
Heat‑transfer booster: supports more efficient thermal exchange for improved system efficiency
Sealant‑free formula: no clogging, no masking—safer preventive alternative to sealant‑based additives
Quieter performance: helps reduce noise during operation
Burnout protection: minimizes risk of electrical stress and costly compressor failures
Corrosion defense: addresses root‑cause contaminants to reduce corrosion
Extends equipment life: helps prolong compressor and overall system longevity
All‑in‑one treatment: system protector and performance enhancer that streamlines maintenance
Ideal for preventive maintenance: effective on both older retrofits and brand‑new residential systems
Reliable, consistent operation: supports stable performance season after season

OVERHAUL is an essential tool for maintaining the health and efficiency of your HVAC system. Its powerful formula and versatility make it a valuable asset for professionals and homeowners alike.

Directions – Xpress OverHaul – HVAC acid/moisture eliminator plus system enhancer:

This product must be used in accordance with the following directions and by professionals only.

Always read the product label and Safety Data Sheet (SDS) for complete precautionary and first aid information before use.

XPRESS SEAL is designed for quick and effective leak sealing in HVACR systems. Choose the method below that best suits your equipment and job site conditions.

General Safety & Pre-Installation Checks (Applicable to All Methods)

Before beginning, ensure the system is ready and you have the correct Xpress Overhaul product for the system’s tonnage.

Safety First: Always wear appropriate personal protective equipment (PPE), including safety glasses and protective gloves, when working with refrigerants and sealants.
Identify Ports: Clearly identify the low-side (suction) and high-side (liquid) service ports on the system.
System Running & Mode:
- Ensure the HVACR system is powered on and running, with the compressor engaged.
- If working on a heat pump, set the system to Cooling Mode for optimal sealant distribution.
System Charge: Verify the system has an adequate refrigerant charge. Xpress Overhaul can be injected into a fully charged or partially low system; if significantly low, you may use refrigerant to push the sealant (see Traditional Method alternative).
Refrigerant Compatibility: Confirm the system is NOT an ammonia (NH3) system, as Xpress Overhaul is not compatible.
Xpress Overhaul Size: Ensure you have selected the appropriate Xpress Overhaul cartridge size for the system’s tonnage (e.g., XPS-Mini, XPS-5T, XPS-60T).
Inspect Xpress Inject Tube: Do not bend, cut, or deform the tube. Check to ensure small nitrogen bubble is present and free moving in the tube.

After injecting Xpress Overhaul, it’s crucial to allow the product to fully circulate and activate:

Run Time: Run the AC unit for a minimum of one (1) hour immediately after injecting Xpress Overhaul. This ensures thorough circulation of the sealant throughout the system. For larger systems or very cold conditions, allow for even longer run times (e.g., 2-4 hours).
System Monitoring: Monitor the system’s operating pressures and temperatures. Xpress Overhaul is designed not to alter system performance or clog metering devices.
Leak Verification: After the recommended run time, verify leak resolution using standard diagnostic methods.
Documentation: Document the application of Xpress Overhaul in the system’s service log, including date, product size, and method used.

Important Notes for Professionals

Refrigerant Charging Concurrent with Sealant: If the system is low on refrigerant, Xpress Overhaul can be injected concurrently with refrigerant charging. Simply connect the inject to the service port and push the sealant into the system using the refrigerant being added, following the appropriate method.
No Pump Down Required: Xpress Overaul does not require pumping down the system for injection, regardless of refrigerant type.
Polymer-Free Formulation: Xpress Overhaul is formulated to be “polymer free” while in the tube and circulating through the system, protecting sensitive system components.
