Quantum apprentice connecting the refrigerant lines to a split-system outdoor unit

Comfort done properly

A split system is only as good as its installation. We look at the room size, orientation, insulation and where the outdoor unit can go, then recommend a system that will actually do the job.

Because we’re electricians, the dedicated circuit and switchboard work is handled by the same team. One booking, one invoice, one team responsible for the result.

“Matt and his team from Quantum Electrical Kalamunda are amazing! They have helped us with all things electrical from big to small numerous times and we wouldn’t go with anyone else. They are reliable, honest, upfront and affordable. Nothing was too big or too small of an issue, and they were able to help us with all of our jobs with short notice. They are a great local business that I recommend to all!”

Frequently asked questions

What size air conditioner do I need?

It depends on the room size, ceiling height, insulation, windows and orientation. We assess this on site or from photos and recommend the right capacity.

Do I need a switchboard upgrade for air conditioning?

Often not. Each split system needs its own circuit, so we check your board has space and suitable protection. If an upgrade is needed, we’ll explain why.

How long does installation take?

A standard back-to-back installation is usually completed in a few hours. More complex installs are scheduled accordingly.
