United Rentals Products & Services

General Equipment Rentals

United Rentals offers a large fleet of construction and industrial equipment including earthmoving machines, forklifts, compressors, aerial equipment, generators, lighting, material-handling equipment, and many other equipment categories. Rental agreements can support short-term jobs, long-term projects, shutdowns, maintenance operations, and emergency needs.

Aerial Work Platforms

The company’s aerial fleet includes boom lifts, scissor lifts, vertical lifts, and related access equipment. Aerial equipment represented approximately 22% of United Rentals’ rental revenue by fleet type in 2025.

General Tools and Light Equipment

United Rentals rents portable tools and light equipment for construction, maintenance, industrial shutdowns, and contractor operations. The category includes cutting, drilling, fastening, material-handling, welding, surface-preparation, and other specialized tools.

Power & HVAC

United Rentals provides temporary generators, electrical distribution, heaters, air conditioning, chillers, and other temporary-power and climate-control systems. These services are used for construction, disaster response, manufacturing, events, renovations, and emergency outages.

Climate Solutions

Climate Solutions teams help customers manage temporary heating, cooling, ventilation, humidity, and temperature-control needs. Services can support industrial processes, facilities, healthcare construction, seasonal demand, and emergency conditions.

Fluid Solutions

Fluid Solutions provides pumps, tanks, filtration equipment, hoses, fittings, and engineered fluid-management systems. These solutions support construction dewatering, industrial operations, municipal projects, environmental work, and emergency response.

Trench Safety

United Rentals provides trench boxes, shoring, shielding, confined-space equipment, and excavation-support solutions. The company operates a large trench-safety network and combines equipment rental with engineering support and training.

Reliable Onsite Services

Reliable Onsite Services provides portable toilets, restroom trailers, showers, sanitation equipment, and related servicing for jobsites, events, disaster-response operations, and other temporary facilities.

Storage Containers & Mobile Offices

United Rentals rents storage containers, ground-level offices, mobile office trailers, and modular space solutions. These products help customers create temporary storage, workspaces, field offices, and site facilities.

Tool Solutions

Tool Solutions supports industrial sites and construction projects with managed tool inventories, tool trailers, specialized equipment, and related services. The service can help large projects reduce tool loss and simplify procurement.

Commercial Trucks

Selected United Rentals locations offer commercial trucks and related transportation equipment to support construction and industrial customers.

Surface Protection Matting

United Rentals provides temporary access and ground-protection matting for construction, utilities, energy, infrastructure, and environmentally sensitive worksites. Surface-protection mats represented approximately 4% of 2025 rental revenue by fleet type.

Equipment Sales

United Rentals sells used rental equipment after units rotate out of its active fleet. It also sells selected new equipment, helping customers purchase rather than rent when ownership better fits their operational needs.

Contractor Supplies

The company sells contractor supplies and related consumables through selected branches. These products complement rented equipment and help customers reduce the number of vendors required for a jobsite.

Equipment Repair and Maintenance

United Rentals provides maintenance, inspection, and repair services for eligible customer-owned equipment. Service programs can reduce downtime and extend equipment life.

Operator Training and Certification

United Rentals offers safety and operator-training programs for qualifying equipment categories. Training helps employers support safer worksites and meet applicable operator requirements.

Total Control is United Rentals’ digital fleet-management platform for managing rented and customer-owned equipment. Customers can monitor utilization, equipment status, spending, and return timing to improve efficiency.

How to Reach a Real Person at United Rentals

For most rental, delivery, pickup, branch, billing, equipment, or account problems, call 844-873-4948. This line is staffed as 24/7 Customer Care, which makes it the best general route when you are unsure which branch or department should handle the matter. Have your rental account number, contract number, equipment ID, jobsite address, invoice, branch location, and contact details ready.

For questions about which equipment or specialty solution is appropriate, call 833-374-8622. For active jobs, the local rental branch or assigned sales representative is often faster because they have direct access to delivery schedules, equipment availability, jobsite requirements, service records, and local account information.

Corporate or investor matters should use the Stamford office or Investor Relations, not Customer Care. For an unresolved service complaint, document the branch involved, dates, rental contract, employees contacted, downtime, additional charges, and any promised credits or repairs before escalating.

How to File a Complaint Against United Rentals

Complaints can involve rental equipment condition, delayed delivery, service failures, billing, damage charges, safety, branch conduct, deposits, equipment availability, contract terms, or customer-account issues. Before escalating, gather the rental contract, invoice, branch location, equipment number, photographs, delivery or pickup records, email correspondence, and names of employees previously contacted.

Step 1: Contact Customer Service

Call United Rentals 24/7 Customer Care at 844-873-4948 and explain the problem. Provide the account number, contract number, equipment information, jobsite location, and the branch involved. Ask the representative to record the issue and route it to the appropriate local or specialty team. Keep any case number and note the time and name of the representative.

Step 2: Contact the Relevant Department

If the issue relates to Power & HVAC, Trench Safety, Fluid Solutions, Tool Solutions, Reliable Onsite Services, or another specialty division, request that the complaint be handled by that specialized business. For rental availability, delivery, equipment condition, or jobsite service, the local branch is often the most appropriate department. Provide photos or service records when the issue concerns equipment performance.

Step 3: Request Supervisor or Management Review

If frontline support does not resolve the problem, ask for the branch manager, district manager, account manager, or Customer Care supervisor. Explain what has already happened, what operational or financial impact the issue caused, and what remedy you are requesting. For commercial accounts, include the purchase order, rental agreement, invoices, and any written service-level commitments.

Step 4: Use the Company’s Written Complaint Channel

Use United Rentals’ official Contact Us form to create a written record. Include your company name, account number, address, phone number, subject, and detailed explanation. Written complaints are especially useful for billing disputes, service-performance concerns, or matters involving multiple rentals or branches.

Step 5: Contact Corporate Headquarters

For a serious unresolved matter, send formal written correspondence to United Rentals, Inc., 100 First Stamford Place, Suite 700, Stamford, CT 06902. Include copies of relevant contracts, invoices, photos, case records, and prior correspondence. Clearly state what resolution you are requesting and why the previous branch or Customer Care process did not resolve the issue.

Step 6: Use the Specialized Complaint or Dispute Department

For complex commercial accounts, billing disputes, damage claims, or contractual issues, ask Customer Care or the account representative to route the complaint to the department responsible for credit, billing, legal, risk, or contract administration. Safety-related equipment issues should also be documented immediately with the branch and relevant safety or service team so the equipment can be inspected.

Step 7: File With the Appropriate Regulator

The appropriate regulator depends on the complaint. Workplace safety concerns can involve OSHA or the applicable state occupational-safety agency, while vehicle, transportation, environmental, or equipment-related matters may involve other federal or state authorities depending on the circumstances. Consumer issues involving rental practices may also fall within state consumer-protection jurisdiction.

Step 8: Use Consumer Protection or Financial Dispute Options

For disputed card charges, customers can contact the card issuer after first attempting to resolve the matter with United Rentals. General consumer complaints may also be submitted to the state Attorney General or consumer-protection office. Commercial customers should review their rental agreement, purchase order, and contractual dispute provisions before pursuing outside remedies.

Step 9: Consider Formal Legal or Arbitration Procedures

If the complaint involves significant damages, contractual liability, personal injury, property damage, or a substantial billing dispute, review the rental contract for governing-law, indemnity, dispute-resolution, and venue provisions. Preserve photographs, service reports, delivery records, communications, and invoices. For substantial commercial disputes, legal advice may be appropriate before arbitration or litigation.
