When it comes to Autumn in Auckland, you never quite know what you’re going to get. One minute it’s a crisp, golden morning, and the next, you’re wondering if summer has staged a comeback. With temperatures bouncing between warm afternoons and chilly evenings, now’s the perfect time to make sure your heat pump isn’t caught off guard when winter properly arrives.

At Air Conditioning Group, we’ve seen what happens when people leave their air con and heat pumps to fend for themselves. Spoiler alert: it usually involves sky-high power bills, underwhelming heating, and emergency repair calls at the worst possible moment. So, before you’re wrapped in three layers of regret come winter, here’s how to get your HVAC system in top shape for autumn.

 

1. Give Your Heat Pump a Bit of TLC

Look, we get it—your heat pump worked hard all summer, tirelessly blasting cool air while you basked in comfort. But just like a car after a long road trip, it needs a bit of attention before shifting into heating mode.

First, let’s talk filters. When was the last time you checked yours? If you can’t remember then you’re probably due for a clean. A clogged filter makes your system work harder, chewing through electricity while delivering lacklustre airflow. A quick clean (or replacement, if it’s beyond saving) is one of the simplest ways to improve efficiency and air quality.

Next up: the outdoor unit. If your heat pump’s external component is surrounded by leaves, cobwebs, or whatever your local wildlife has decided to store there, it’s not going to run as efficiently. A quick tidy-up around the unit ensures it can ‘breathe’ properly, keeping performance at its best.

And if you really want to avoid a mid-winter breakdown, an annual professional service is your best bet. A trained technician can spot small issues before they turn into wallet-draining disasters.

 

2. Stop Wasting Power: Smart Ways to Cut Costs This Autumn

Heating your home shouldn’t mean dreading the power bill. If you’re wincing every time you open your electricity statement, your heat pump might not be the problem—it’s how you’re using it.

First mistake? Cranking the thermostat to tropical levels. Setting it to 28°C doesn’t make your home heat up faster; it just makes your unit work overtime, burning through power. The sweet spot? A comfortable 18-22°C. Warm enough to keep the chill away, but efficient enough to keep costs down.

Then there’s the ‘on-off’ game some people play, thinking they’re being clever. Constantly turning your heat pump on and off forces it to work harder every time it restarts. If you’re home for most of the day, set it to a steady temperature rather than making it battle extremes.

Another easy win? Using timers. Heat pumps with programmable timers let you warm up the house just before you wake up or return home, without running all day. It’s a simple trick that can make a noticeable difference in energy use.

 

3. Fresh Air vs. Warmth: Striking the Right Balance

There’s something undeniably refreshing about crisp autumn air—until you realise you’ve turned your living room into an icebox because you left the windows open too long.

Ventilation is important, but it’s all about timing. The best time to let fresh air in is during the warmest part of the day. Open windows for a short burst rather than leaving them ajar for hours, so you’re swapping stale indoor air without undoing all the work your heat pump just did.

And let’s not forget humidity control. Auckland’s autumn weather still brings plenty of moisture, which can lead to condensation (and its annoying cousin, mould). Many modern heat pumps have a dehumidifying mode—a handy feature that keeps your home dry and comfortable without making it feel like the Sahara.

 

4. Small Adjustments, Big Comfort Gains

Ever walked into a room and felt an unexplained chill, even though the heat pump is running? Your furniture might be to blame. If a couch, curtain, or an ambitious indoor plant is blocking airflow, you’re not getting the full benefit of your heating system. Rearranging things slightly can make a massive difference in warmth distribution.

Speaking of warmth, if you notice your home leaks heat fast, then your heat pump is likely working harder than it should be. Simple fixes like door draught stoppers, heavier curtains, and even floor rugs can help trap the heat inside, meaning you stay cosy without cranking up the temperature.
