Why Preparation Matters Before AC Installation

A well-prepared home reduces installation time, prevents accidental damage, and avoids extra fees linked to access challenges. Most delays during AC installs come from blocked indoor walls, outdoor obstructions, pets underfoot, or unclear roof space access.

This guide removes the guesswork and helps you prepare like a pro.

How to Prepare for AC Installation — Before the Team Arrives

To prepare for AC installation, start by clearing access so installers can work safely and efficiently. These steps apply whether you’re installing a split system or a ducted system in a Perth home.

1. Clear Wall Space for the Indoor Unit

Remove furniture, artwork, mirrors, shelves, TV units, and fragile items from the wall where the indoor unit will be installed. Installers need several metres of open workspace to mount the unit and run cabling.

2. Clear the Outdoor Area

Make sure the outdoor unit location is free from bins, pot plants, garden tools, or stored materials. If a slab is being installed, ensure the ground around it is accessible.

3. Provide Clear Access Pathways

Open pathways help avoid delays. Ensure installers can move tools and ladders between the driveway, indoor area, switchboard, and roof space without obstruction.

4. Roof Space Entry for Ducted Installations

If you’re preparing for a ducted aircon install, roof access is one of the most important steps.

  • Clear the area directly under the manhole.
  • Move furniture so the ladder can safely open and lock.
  • Remove stored items blocking roof walkways.
  • Ensure any attic flooring is stable for safe entry.

5. Switchboard and Power Access

Make sure the switchboard is unlocked and all pathways to it are clear. Some installations may require new circuits or breaker upgrades, and installers need full access to perform safety checks.

6. Secure Pets Early

Pets can become stressed by noise, strangers, or open doors and gates. Secure pets in a separate room or outdoor area before installers arrive to keep everyone safe.

7. Allocate Parking for the Installation Vehicle

Most installation delays occur when installers cannot park close enough to unload ladders, tools, and units. Reserve the driveway or closest available parking bay on the day.

8. Decide on Thermostat or Controller Placement

For ducted systems, choose a location that is convenient, visible, and away from heat sources. Installers can advise you on ideal thermostat placement during the final walkthrough.

AC Installation Day Tips — What to Expect

These AC installation day tips help you stay prepared and avoid last-minute surprises on the day of installation.

Clear Access Before the Team Arrives

Even small obstacles can slow down the install. Double-check that all access points and work areas are clear and safe.

Stay Available for Questions

Installers may need approval for unit positioning, pipework routes, or controller height. Being available ensures quick decisions and avoids return visits.

Expect Some Noise and Power Shutdowns

Drilling, ladder movement, and short power interruptions are normal. If you’re working from home, plan meetings around these moments.

Keep Kids Away from Tools and Work Zones

Children are naturally curious, but installation involves tools, wiring, and ladders. Set clear boundaries to keep them safe.

After Installation — Your Final Checks

Once your system is in place, there are a few steps to ensure everything is handed over correctly and operating as expected.

Walk Through the System With the Installer

Confirm airflow, zoning (if ducted), and basic functions. Ask questions about modes, filters, and maintenance schedules.

Check Documentation and Warranties

You should receive product details, warranty information, and recommended service intervals. Keep these in a dedicated folder or email archive.

Inspect the Work Area

A professional installer leaves the workspace tidy. Confirm indoor and outdoor areas are clean and free from packaging or leftover materials.
