Hey folks, Mike Sanders here. When the summer heat hits, and your regular HVAC system is under repair or you need extra cooling in a pinch, temporary cooling units like spot ACs and 5 ton portable air conditioners can be lifesavers. Whether you’re managing a construction site, a commercial space, or just need spot cooling at home, understanding your options is crucial.
Today, I’m going to walk you through everything you need to know about temporary cooling units, what to expect from spot aircons, and how 5 ton portable AC units can give you powerful, flexible cooling wherever you need it.
What Are Temporary Cooling Units?
Temporary cooling units are portable or semi-permanent HVAC solutions designed to provide cooling on a short-term basis. They’re often used when:
-
Your central air conditioner is undergoing repair or replacement
-
You’re hosting an event in a space without permanent AC
-
You need spot cooling in a large commercial or industrial space
-
You require extra cooling capacity during unusually hot periods
-
Construction sites need climate control for worker safety and equipment
The beauty of temporary cooling is flexibility—you can move these units where you need them, often without major installation.
Types of Temporary Cooling Units
1. Spot AC / Spot Aircon
A spot air conditioner or spot AC is a small, portable cooling unit designed to cool a very specific area or “spot.” These units are perfect for cooling workstations, server racks, or any small zone where focused cooling is needed.
Spot ACs typically come with features like:
-
Compact size and portability
-
Easy setup and minimal installation
-
Targeted cooling with adjustable louvers
-
Some models include dehumidification for moisture control
2. Portable Air Conditioners (PACs)
Portable air conditioners are self-contained units with an exhaust hose that vents hot air outside through a window or wall opening. They’re larger than spot ACs and capable of cooling bigger spaces.
They come in various sizes, with capacities measured in BTUs (British Thermal Units). For example, a 5 ton portable air conditioner is a beast, capable of cooling roughly 60,000 BTUs — enough to handle sizeable commercial or residential areas.

3. Evaporative Coolers (Swamp Coolers)
While not technically air conditioners, evaporative coolers provide temporary cooling by evaporating water into the air. They work best in dry climates and can be an energy-efficient alternative in the right environment.
When to Choose a 5 Ton Portable Air Conditioner
A 5 ton portable AC unit packs serious cooling power. Here are some common scenarios where you might need this size:
-
Large event tents or outdoor functions where permanent AC isn’t practical
-
Construction trailers or mobile offices needing reliable climate control
-
Server rooms or data centers with high heat loads
-
Temporary retail or commercial spaces during peak summer months
A 5 ton portable air conditioning unit offers mobility without sacrificing performance. Many come on caster wheels for easy movement, and some have ducting options to vent hot air more efficiently.

Benefits of Temporary Cooling Units
-
Flexibility: Move your cooling where you need it, when you need it.
-
Cost-effective: Avoid costly HVAC repairs or upgrades when a temporary fix will do.
-
Quick setup: Most units can be up and running in under an hour.
-
Reduced downtime: Keep business or work flowing even when permanent HVAC is offline.
-
Energy savings: Spot ACs cool only the areas you need, saving power compared to central systems.
Downsides to Keep in Mind
-
Noise: Portable units can be louder than central systems.
-
Space: Some units require venting through windows or walls, which might limit placement.
-
Maintenance: Temporary doesn’t mean maintenance-free—filters and coils still need care.
-
Capacity: Make sure your unit is properly sized to avoid undercooling or overworking the AC.
How to Properly Size a Temporary Cooling Unit
Sizing is critical. An undersized unit will struggle to keep up, while an oversized one wastes energy and can cause discomfort.
-
Use BTU calculators like this one from CoolCalc to estimate your cooling needs.
-
Consider factors such as room size, ceiling height, sun exposure, and equipment generating heat.
-
For spot cooling, consider how many people or pieces of equipment need direct airflow.
Temporary Cooling vs. Permanent Systems: When to Upgrade
Temporary cooling is great for emergencies, seasonal needs, or specific jobs, but if you find yourself relying on spot ACs or portable units regularly, it might be time to upgrade your permanent system.
For example, the Goodman 3 Ton 14.5 SEER2 R-32 Bundle is a fantastic mid-size permanent cooling solution. It’s energy efficient, reliable, and uses eco-friendly R-32 refrigerant. You can check out the full details on the bundle here.
Installation Tips for Portable Air Conditioners
-
Ensure proper venting: Use the included hose to vent hot air outdoors—don’t try to vent into another room.
-
Position near a window or vent: This helps maximize cooling efficiency.
-
Keep filters clean: Regularly check and clean or replace filters to maintain airflow and indoor air quality.
-
Use drain pans or hoses: Some units require water drainage, especially in humid climates.

Conclusion: Mike’s Final Thoughts
Temporary cooling units like spot ACs and 5 ton portable air conditioners are vital tools when you need fast, flexible cooling without committing to a full HVAC overhaul.
Whether you’re a contractor, event planner, or homeowner dealing with an unexpected breakdown, these units can bridge the gap and keep you comfortable. But remember—temporary doesn’t mean permanent.
