If you live in South Canterbury, you’ve probably noticed more and more homes with heat pumps running year-round. That’s because they work. But getting a heat pump installed properly isn’t as simple as grabbing one off the shelf and plugging it in. Whether you’re in Ashburton, Timaru, or out towards Twizel, there are a few things you really ought to know before you commit.
We’ve installed thousands of units across the region. Here’s the real-world, straight-up advice most people wish they heard before getting one.
Key Takeaways

- Correct placement of indoor and outdoor units matters more than people think
- A trusted local installer can save you thousands in long-term efficiency
- Cheap quotes usually mean shortcuts
- Cool Air has been serving this region with expert installation and honest advice for years
Why Heat Pumps Are a Smart Choice for South Canterbury Homes
In regions like Ashburton and Timaru, where winter mornings hit below zero and summer afternoons can push high 20s, heat pumps give year-round value. They’re energy efficient, fast-acting, and quieter than most traditional systems.
Unlike panel heaters or wood burners, heat pumps deliver consistent warmth and cooling without the ongoing mess or high power bills. And because they run on electricity, they integrate easily with solar setups many Canterbury homes are now adding.
As energy costs rise and building codes tighten, heat pumps are quickly becoming the go-to heating and cooling system for new builds and retrofits alike. Their dual functionality means you get more for your investment. One unit handles both extremes of the South Island’s unpredictable climate.
What Most People Get Wrong About Heat Pumps
The biggest mistake we see? Poor sizing and cheap installs. People assume all heat pumps are the same or that one unit can handle a four-bedroom home. That’s costly.
Installing a unit that’s too small means it’ll work overtime and wear out faster. Oversized units? They cycle too quickly, burning through power and underperforming.
Another common myth is that heat pumps are expensive to run. In reality, a well-installed unit costs far less than portable heaters or older electric systems, especially when it’s tuned for the space. Bad installs, incorrect placement, or blocked filters? That’s where costs climb.
We’ve also seen people go the DIY route or hire unlicensed installers just to save a few bucks. That shortcut often ends with poor airflow, refrigerant issues, or placement problems that lead to long-term inefficiencies.
What to Look for in a Quality Heat Pump
Heating Performance and COP Rating
If you live in a frost-prone area like Geraldine or Fairlie, don’t waste time on underpowered units. Look for heat pumps with high Coefficient of Performance (COP) ratings and cold climate engineering. These models pull more heat per kilowatt used.
COP ratings show how efficient your heat pump will be. The higher the number, the better. You want a system built to perform when temperatures drop below zero, not one that limps along while you still need to run a backup heater.
Noise, Filters, and Airflow
In bedrooms or media rooms, a quiet unit is gold. Newer models run whisper-quiet and have smart filters to reduce allergens. Airflow control matters too. Being able to direct warm or cool air properly changes how quickly a room gets to the right temperature.
A good installer will position the unit so air spreads evenly without blowing directly onto beds or seating areas. This might sound minor, but it has a big impact on day-to-day comfort.
Useful Features
Forget gimmicks. Features like Wi-Fi control, 7-day timers, or motion sensors actually make daily life easier. They allow better energy management, especially when no one’s home.
Timers let you warm the house before you get up. Motion sensors reduce waste when rooms are empty. And smartphone apps give full control while you’re out and about. These tools help cut your power bill without compromising comfort.
How to Choose the Right Size for Your Space
This is where a seasoned installer like Cool Air makes all the difference. We look at the room size, insulation, ceiling height, and even sun exposure to match the unit to your needs. You’ll never get that level of assessment from a big box store.
General rule of thumb? A 6kW system suits most average open-plan living areas but without seeing your layout, we’d never guess. Guessing leads to disappointment. That’s why Cool Air does on-site evaluations for every install.
If you’ve got multiple floors, high ceilings, or a draughty old villa, we’ll tell you straight what you need, not just what’s on special this week.
What Matters Most: Indoor vs Outdoor Placement
You might think it’s a non-issue, but we’ve seen plenty of installs go wrong just from bad positioning. Indoor units should be placed where air can circulate freely, not behind doors or above furniture. Outdoor units need shelter from frost, wind, and debris, with enough clearance for airflow.
Poor placement leads to blocked coils, noise issues, and unnecessary maintenance. Cool Air always factors this in from day one. We check wall strength, sun exposure, frost zones, and even where the condensation will drain.
An outdoor unit too close to a fence or wall will recirculate hot or cold air, reducing performance. Too exposed, and it’ll ice up in winter. We get this right because we’ve seen what happens when it’s done wrong.
Who Installs It Makes All the Difference
This can’t be overstated. We’ve been called in to fix so many jobs botched by under-qualified installers or rushed jobs. Choosing an accredited, experienced installer like Cool Air gives you peace of mind.
We’re not just box droppers. Our team has decades of experience installing, maintaining, and optimising heat pumps across the South Canterbury region. From Oamaru to Twizel, we’ve built a reputation on honesty, precision, and ongoing support.
We’re also familiar with council regulations and manufacturer specs, which means your system will meet warranty conditions and perform to its full potential. With Cool Air, there’s no guesswork, just proven expertise.
Running Costs and Maintenance
Here’s the good news: modern heat pumps are incredibly efficient. A properly sized unit in a well-insulated home can cost less than a dollar a day in winter. But only if it’s looked after.
Filter cleaning is easy and should be done every few months. But annual servicing by a pro like Cool Air ensures refrigerant levels, drainage, and system health stay in check.
We also help you program your settings to get maximum output with minimal power use. We show you the ideal temperature ranges, fan speeds, and timer setups that reduce waste and boost comfort. This isn’t just install and run. We will stay involved.
Think Long-Term, Not Just Install Day
When it comes to heat pumps, the long game matters. That’s why sizing, placement, brand, and installation all need to be done right the first time. A quality system should last 10 to 15 years. Get it wrong, and you’ll be paying for it in both comfort and power bills.
