5 Common Winter Mistakes (And How to Avoid Them)
26 May 2026
Winter in Southland has officially arrived. The frosts are back, washing takes approximately 14 business days to dry, and everyone suddenly becomes very interested in power bills.
But while most of us are doing our best to stay warm, there are a few common winter habits that can quietly make homes colder, damper, and more expensive to run. Here are some of the biggest winter mistakes we see — and what to do instead.
Leaving Your Heat Pump Running 24/7
This one surprises people. A lot of homeowners assume it’s cheaper and more efficient to leave their heat pump running constantly through winter. But modern heat pumps are actually designed to heat homes quickly and efficiently from a cold start.
In most cases, you don’t need to leave your heat pump running all day while nobody’s home. Instead:
✔ Turn it on when you get home
✔ Use timers or Wi-Fi scheduling if available
✔ Increase fan speed for a quicker warm-up
✔ Keep temperatures sensible (around 21°C is usually ideal)
And one very important tip: Always use HEAT mode, not AUTO mode, which can increase power use significantly.
Drying Washing Inside Without Ventilation
We understand. Southland winters and outdoor washing lines are not always great friends. But drying clothes indoors without ventilation adds a huge amount of moisture into your home.
That extra moisture often ends up as:
- condensation on windows
- dampness
- musty smells
- even mould
If you do dry clothes inside:
✔ Open windows slightly when possible
✔ Use extractor fans or dehumidifiers
✔ Run ventilation systems
✔ Or use a properly vented dryer
Ignoring Condensation
Many people think wiping water off the windows every morning is just part of winter. But excessive condensation is usually your home trying to tell you something.
It often points to:
- excess indoor moisture
- moisture coming from the ground underneath the house
- poor ventilation
- inconsistent heating
- insufficient insulation
A healthier home should stay drier and more comfortable — even in the middle of winter. If you have condensation on your windows every morning it’s time to book a home assessment and see how we can help you.
Forgetting About Heat Pump Maintenance
Your heat pump works hard through winter — but it needs a little help too. Dirty filters can reduce efficiency, increase running costs, and make your system work harder than it needs to.
A simple weekly vacuum of the filters can make a noticeable difference. And annual professional servicing helps keep everything running efficiently long-term.
Spending Money in the Wrong Order
This is one of the biggest mistakes homeowners make. People often jump straight to expensive upgrades without understanding what their home actually needs first.
Sometimes:
- insulation delivers the biggest improvement
- ventilation solves the moisture problem
- or heating becomes far more effective after reducing heat loss
Every Southland home is different. A home assessment focuses on the upgrades likely to deliver the biggest improvement in comfort, health, and energy efficiency in your home.
Winter Doesn’t Have to Mean Cold and Damp
A warm, dry home feels better, costs less to heat efficiently, and supports healthier living through winter. And often, a few small changes can make a surprisingly big difference.
