As the temperature drops, shutting down your evaporative air conditioner correctly can make a noticeable difference in your home’s comfort and energy efficiency. At Deadshort Services, we recommend taking the time to winterize your unit properly—it’s a simple step that delivers multiple benefits.
1. Improve Your Heating Efficiency
If your unit doesn’t have a winter flap or isn’t covered, it becomes an open path for cold Adelaide air to enter your home. Warm air from your heater can also escape through ceiling vents and the exposed cooler pads, forcing your system to work harder. By covering your unit and closing vents, you retain heat and reduce energy costs.
2. Prevent Bacteria and Algae Growth
Evaporative coolers hold water in a reservoir at their base. If left stagnant over winter, this can become a breeding ground for bacteria and algae. Isolate the water supply, then drain and clean the reservoir with warm soapy water before rinsing thoroughly.
3. Extend the Life of Your Cooler
Winterizing protects vital components such as pads, pumps, and float valves from freezing and weather damage. A proper cover also stops draughts and keeps birds or pests out.
Our team at Deadshort Services can assist with professional winter shutdowns of evaporative systems across Adelaide. One call, one number, multiple trades—done right the first time.
Need help winterizing your air conditioner?
At Deadshort Services, we provide a thorough and reliable Winter Shutdown Service for evaporative air conditioners to help protect your system during the colder months and ensure it’s ready to perform at its best when summer returns.
Our winter shutdown service includes:
Inspection and Assessment
we will carry out a full inspection of the air conditioner evaporative unit, including filter pads, water lines, and electrical connections. We will check the condition of the main components and report any signs of wear or damage.
Clean & Flush Filter Pads
Pads will be cleaned and flushed to remove any dust, dirt, and mineral deposits. If they show signs of deterioration, we’ll let you know if replacement is recommended for next season.
Drain and Clean Water Reservoir
The unit’s basin is drained, scrubbed with warm soapy water, and flushed to eliminate dirt, scale, and biological buildup. We then dry the reservoir to prevent stagnant water over winter.
Pump & Channel Maintenance
The pump , water filter, and distributor channels are cleaned and flushed to ensure free-flowing operation and prevent clogging or corrosion.
Isolate Water and Power
We shut off and isolate the water supply and safely disconnect the power either at the circuit breaker or within the evaporative air conditioner.
Cover & Secure the Unit
We install a customer-supplied winter bag cover or shut down cover and secure in place to protect the unit from the elements, debris, and pests.
Seal Interior Vents (if required)
We can assist with closing or sealing internal ceiling vents to minimize draughts and maintain heating efficiency inside your home.
Why It Matters:
Proper winterization prevents cold air ingress, reduces the risk of algae and bacteria growth, and extends the life of your air conditioning system. It also gives you peace of mind knowing above all it’s been done right by Adelaide’s trusted multi-trade professionals.
