Best Time to Deep Clean Your Aircon: Winter or Summer?
If you’ve ever waited until the first scorching day of summer to think about your air conditioning, you’re not alone. For many Redcliffe and Moreton Bay homeowners, air conditioning cleaning is often an afterthought. But when it comes to your family’s health, comfort, and energy costs, timing is everything.
In this guide, we’ll compare winter aircon cleaning and summer cleaning to help you decide the best time to book a deep clean—before it’s too late.
Why deep cleaning your air conditioner matters
Your air conditioning system works hard throughout the year. In summer, it’s cooling down in hot, humid rooms. In winter, especially with split system units, it’s often used for heating. Over time, this constant use leads to:
- Dust and dirt buildup
- Mould growth from condensation
- Reduced airflow and cooling efficiency
- Rising energy consumption
A proper split system servicing and deep cleaning targets internal components, such as coils, drain trays, and fan barrels, to remove built-up contaminants. This improves energy savings, air quality, and your unit’s performance.
If your air conditioners haven’t been cleaned in the last 12 months, now is the time to act.
The case for winter aircon cleaning
Here’s why winter might be the smartest time to book:
1. Beat the summer rush
Air conditioning businesses across Brisbane and the Gold Coast get slammed in the lead-up to summer. Booking a deep clean in winter means better availability and a faster turnaround, especially if you want your local technician to arrive on time.
2. Identify issues before peak season
Servicing in winter gives you time to detect problems, replace worn parts, or consider a new air conditioning installation before summer stress reveals bigger faults.
3. Improve indoor air quality during closed-up months
Winter often means closed windows and less ventilation. That means if your system is blowing dirty air, you’re trapped with it. Cleaning now helps ensure a clean and healthy indoor environment.
4. Support energy savings
A clean air conditioning unit runs more efficiently. According to the Queensland Government, regular maintenance and cleaning help reduce energy consumption and improve home sustainability. This supports long-term energy efficiency goals, especially for those exploring renewable energy or smart climate control systems.

The argument for summer aircon cleaning
If you missed the winter window, there are still good reasons to clean in summer:
1. You’ll notice problems quickly
If your unit blows warm air, smells musty, or makes strange noises, summer usage will often highlight the issues, prompting people to book a professional service.
2. You can improve performance instantly
A mid-season clean can quickly improve cooling power and cost-effective performance, especially if filters and fans are clogged.
3. It’s better than not cleaning at all
If you’ve skipped annual maintenance, summer cleaning can still restore function, prevent breakdowns, and save your air con from further wear and tear.

Real feedback from customers
“Great service. From initial phone call to completion in less than 24 hours. Paul turned up an hour early—an honest assessment of my A/C. I thought there was a problem, but it turned out to be my fault. Paul could have told me anything; I wouldn’t have known any better. I have already passed his number on to others.” — Ray Beer.
“Paul is a cracking bloke, and his service is fantastic. Our air conditioners are relatively new, and we didn’t realise how minging and dirty they were! We are so pleased with the service we have booked for next year already. Highly recommend.” — Jake Green.
“Paul was very thorough in servicing our very mouldy aircon; I am beyond impressed in the work he performed. Paul honestly went above and beyond in my expectations; he was everything you could hope for. I have no doubt he is the best in Redcliffe! My aircon is ❄️ icy cool ❄️ and feels brand new again! HIGHLY RECOMMENDED! Thanks, Paul.” — Molly Plymin
