Frequently Asked Questions

  • If you need a temporary cooling or heating solution for your industrial or commercial space, portable rentals can be a perfect choice. Whether it’s a portable air conditioner, air cooler, chiller, or heating unit, going for a rental instead of a permanent solution can be immensely beneficial, especially for emergency HVAC situations, planned shutdowns, and special events or projects.  

    Portable AC and heater rentals are a great choice for hospitals, retail businesses, schools, offices, and many other spaces. If you’re looking for a portable HVAC rental in San Diego, Orange County, or Riverside, Aerco Systems can provide you with the best temporary heating and cooling solutions for your needs.

  • Customers considering a temporary cooling rental often wonder about the difference between chillers and air conditioning units. While both of these systems have the same purpose in terms of controlling air temperature, they have very different ways of achieving this purpose. Here’s how these two HVAC systems differ. 

    Air conditioners

    As its name suggests, an air conditioner is designed to regulate or “condition” the temperature in a room. Depending on the settings, air conditioners can convert air to cold or hot, as well as dehumidify the air. When an air conditioner is set to cool, it will rely on a basic principle of refrigeration, where a condenser will remove heat from the air and transfer it over a coil filled with refrigerant or another similar fluid to be absorbed. Finally, an air conditioner will distribute the cooled air back into the space. 

    Air conditioners are used for both residential and commercial applications. An air conditioner rental would be particularly useful in small buildings, offices, retail outlets, and hospitals that do not have an adequate HVAC solution or need a reliable cooling option in an emergency. 


    In the case of chillers, an absorption refrigeration or vapor-compression cycle is used to remove heat from a liquid. The chilled liquid then passes through a system of pipes or coils, cooling down the air. 

    Chillers are typically water and air cooled. A water-cooled chiller would typically be located inside a facility, with the water that is recycled to an external cooling system or a heat sink. This external cooling method can include a cooling tower. An air-cooled chiller, on the other hand, is usually located outside of a facility and has condenser coils that are cooled by air generated by a fan. Chillers are used in various cooling applications and manufacturing processes, such as assembly processes, MRI machines, and tooling equipment. 

    Whether you are searching for temporary chiller rental services or need an industrial portable air conditioner rental, make sure to contact Aerco Systems. Our rental chillers and ACs are ideal for a full range of residential, industrial, and commercial applications across San Diego, Riverside, and Orange County.

  • The cooling towers we offer can be used in both closed and open-loop applications. If you have a water cooled chiller or a similar unit requiring an open-loop system, the installation procedure will be quite straightforward. All our technicians have to do is connect to the condenser water loop, provide you with an external pump if needed, connect the hoses for condenser water to determine connection points, supply power, and turn on the system. 

    If you need a closed-loop service, on the other hand, we can integrate an external heat exchanger into your system to maintain the closed-loop system’s integrity and provide immediate relief to your building. This is often needed for facilities served by a water source heat pump or similar situations.

  • Numerous industrial and commercial facilities can benefit from a Move and Cool system, also known as Move N Cool. Whether it’s an emergency or a temporary solution for a planned shutdown, a Move and Cool rental would be a great option for the following industries and applications: 

    • Schools 
    • Offices 
    • Healthcare 
    • Server rooms
    • Industrial facilities
    • Outdoor events & projects
    • Moisture removal
