When you switch your air conditioner on, it works to bring the room down to your selected temperature. Dropping the setting extra low doesn’t speed up the process - it can just make the system run longer than needed.

For better comfort and efficiency, set your desired temperature and let your air conditioner do the work.

It was an honour to host the Mitsubishi Electric guests as their time here in Australia is only for 3 days and LMAC was the only Diamond Dealer they visited along with head office in Homebush.

A proud moment for our team and a wonderful opportunity to discuss, give feedback and strengthen the relationship, between our local business and the Mitsubishi Electric team. 🤝

Thank you for taking the time to visit us.
We truly value your support and look forward to continuing to work together to keep our community comfortable! 💙

Reviews like this mean the world to our team!

There’s nothing better than hearing that our customers have felt genuinely looked after from start to finish. 💙

A huge thank you to Danielle and her Dad, John, for taking the time to share these incredibly kind words about their recent air conditioning installation.

What we especially love is this:

“It’s rare to find a team that genuinely cares about their customers and takes such pride in their work.”

That is exactly what we strive for at Lower Mountains Air Conditioning — professional service, quality workmanship and, most importantly, looking after our customers even after the job is complete.

Thank you for trusting our team with your home, John. We’re so pleased we could help — and a 10/10 recommendation certainly made our day! 🙌

Well done to our amazing LMAC team — this is what it’s all about. 💙
