7 signs it’s time to replace your heat pump

During a Kiwi winter, we rely on a few important things – a very warm coat, beanie, a scarf to keep the wind off of our necks while out and about, and at home, our heat pump unit.

7 signs it’s time to replace your heat pump

There’s no denying that having a heat pump makes life so much more comfortable whether you’re battling the chill of the New Zealand winter or the heat of summer. Having a reliable unit in your home can ensure that you’re comfortable and dry throughout the year.

However, there comes a time when your trusty old air conditioner just doesn’t perform as well as it once did.

Excessive noise, costly repairs, unusually high energy costs and uneven heating and cooling are some signs that your heat pump/air conditioning unit might be on the way out.

1. Unit is blowing hot or cold air which is inconsistent to temperature settings

2. Your unit has diminished air flow

3. It’s emitting strange noises or strange smells

4. Your unit is leaking or producing excess moisture

5. Your unit is short cycling (your unit only runs for a short period of time before switching off)

6. Your energy bills have dramatically increased

7. Your unit requires frequent repairs (and is out of warranty)

If you recognise any of the signs, call in a professional to see if repair is an option, or start shopping for a replacement unit.

Comparing a new Daikin unit with an old unit

Our Research and Development team compared the average running costs of an old Daikin ducted system model and Daikin’s current Premium Inverter ducted system. This comparison was based on delivering identical running times from both options and then calculating the running costs.

The good news? Advances in Daikin’s air conditioning technologies have greatly improved energy efficiency.

Here are just some of the improvements:

Inverter technology

An advanced fan motor technology which allows the unit to operate more efficiently than other models. This technology enables the desired temperature to be reached faster, and steadily maintains the temperature without fluctuations.

DC indoor fan motor

Daikin indoor units are equipped with a variable speed high efficiency DC fan motor. By utilising high power permanent magnets instead of the induced magnetism of conventional AC motors, Daikin’s DC motor can deliver significantly higher motor efficiency.

Automatic mode changeover

Automatically selects heating and cooling modes to suit thermo- stat settings and the current room temperature.

Temperature limit operations

Lets you pre-define the temperature range for both heating and cooling to reduce energy consumption.

Efficiency – and more

With a Daikin, efficiency isn't the only benefit. There's also:

Night quiet mode

Outdoor unit noise is automatically reduced by 3 dB when outdoor temperatures fall more than 6°C from the day’s maximum (set during installation).

Intelligent defrost

During heating operation in low ambient temperature conditions, frost can form on the outdoor unit heat exchanger which can reduce your air conditioners performance.

Daikin’s intelligent defrost system constantly monitors a range of system parameters and temperatures to determine the optimum time to commence a defrost operation for maximum performance in cold conditions.

Hot start

Prior to heating, the indoor unit warms to a pre-set temperature before the fan switches on, ensuring only warm air is discharged and eliminates cold drafts.
