January on the Central Coast can be relentless: high temperatures, humid afternoons, and warm nights that make you want to run the air con nonstop. If your system feels like it’s working harder than ever (and your electricity bill agrees), the good news is that many causes are fixable with the right maintenance and settings.
## Why your air con runs constantly in late January
When outdoor heat and humidity spike, your air conditioner has to remove both heat and moisture from inside the home. If the unit is even slightly restricted, it can’t move enough air across the coils, which reduces cooling capacity and forces longer run times.
Coastal areas like Wamberal also experience salty air and higher moisture, which can contribute to grime build-up and mould-friendly conditions inside indoor units if they’re not kept clean.
## The biggest culprits behind high summer energy bills
### 1) Dirty filters and clogged coils
Your filters are the first line of defence. When they’re blocked, airflow drops and the system has to work harder to achieve the same temperature. Over time, dust can also build up on the indoor coil and fan barrel, making cooling less effective and sometimes causing odours.
### 2) Humidity and drainage issues
In humid weather, your air con removes a lot of moisture. If the drain line is partially blocked or the unit is dirty, you might notice a musty smell, water dripping, or inconsistent performance. Moisture plus dust can create a perfect environment for microbial growth.
### 3) Incorrect settings and unrealistic temperatures
Setting the air con very low (for example 18–20°C) can increase run time and cost without improving comfort much—especially if humidity is the main issue.
## Quick settings to improve comfort (without overworking the system)
– Aim for 24–26°C for efficient cooling in most homes.
– On sticky days, try “Dry” mode to reduce humidity and make the room feel cooler.
– Use a higher fan speed initially, then lower it once the room stabilises.
– Keep doors and windows closed while cooling, and make sure vents aren’t blocked.
## Signs your air con needs a service now
If you notice any of the following, it’s worth getting it checked:
– Weak airflow or uneven cooling
– Musty or sour smells when the unit starts
– Water leaking or dripping indoors
– Unusual noises or rattling
– A sudden jump in power bills with no change in usage
## How a professional service helps in peak summer
A proper split or ducted service can restore airflow, improve heat transfer, and reduce strain on the system. It also helps manage moisture inside the unit—important during humid coastal summers—so you’re less likely to deal with odours and performance issues.
At My Air Con Care in Wamberal, Jason focuses on detailed maintenance that supports comfort, efficiency, and cleaner indoor air during the busiest time of the year.
## Summer takeaway
If your air con is running all day, don’t assume it’s “just the weather.” A few targeted fixes—cleaning, drainage checks, and smarter settings—can help your home feel cooler and your system run more efficiently through the rest of summer.
