Heat Pumps & Air Conditioning
Warm in Winter. Cool in Summer.
A modern heat pump does more than heat your home. It also provides efficient air conditioning during summer, helping keep your home comfortable throughout the year. Whether you're replacing an older system or installing one for the first time, we'll help you choose the right solution for your home.
Is Your Home Hard To Keep Comfortable?
Many Waikato homeowners struggle with:
Cold living areas during winter
Some homes lose heat quickly, making it difficult to maintain comfortable temperatures throughout the day.
Hot rooms during summer
Bedrooms and living spaces can become uncomfortable as indoor temperatures rise.
Uneven temperatures throughout the home
Some rooms feel comfortable while others remain too hot or too cold.
Rising energy costs
Older or inefficient heating systems can consume more power while delivering poorer results.
These issues often make the home less enjoyable to live in.
The right system can help create more consistent comfort throughout the year.

One System. Two Jobs.
Heat Pumps Are Also Air Conditioners
Many homeowners are surprised to learn that a heat pump performs two jobs.

Heating during winter
Heat pumps provide an efficient way to keep your home warm during colder months.
Cooling during summer
The same system can also operate as an air conditioner, helping keep indoor temperatures comfortable during warmer weather.
Year-round comfort
With both heating and cooling built into one system, heat pumps provide a practical solution for changing Waikato conditions.
That's why they have become one of the most popular home comfort solutions in New Zealand.
Advice Before Installation
Heat Pump Installation Designed Around Your Home
A good heat pump installation starts well before the unit goes on the wall.
The size and layout of your home, insulation, windows, room orientation and how you actually use each space all influence the heating and cooling solution that's right for you. A system that's too small can struggle to keep up, while an oversized unit can cycle unnecessarily and may not deliver the comfort or efficiency you expected.
Climate Systems takes the time to assess your home before recommending a system. We'll look at where heating and cooling are needed, how air will move through the space, and where indoor and outdoor units can be positioned for effective, efficient operation.
Whether you're replacing an older heat pump, adding heating and cooling to another part of the house, or starting from scratch, we'll recommend a solution based on the home rather than simply selling you a particular unit.
If you want more consistent comfort across several rooms, our Whole Home Comfort Solutions can help you consider the house as one connected system. Where moisture and airflow also affect comfort, explore our Home Ventilation Systems.
If you already have a system that is not performing as it should, Heat Pump Servicing may be the right place to start.
Why Sizing Matters
Getting the Size Right Matters
Choosing the right heat pump isn't simply a matter of matching a unit to the square metres of a room. Ceiling height, insulation, glazing, sunlight, room layout and the way the space is used can all affect the heating and cooling load.
System too small
A unit that is undersized may struggle to heat or cool the space effectively.
System too large
A larger system is not always better and may operate less efficiently than a correctly sized unit.
Poor placement
Even a quality system can underperform if it is installed in the wrong location.
That's why Climate Systems assesses the space before recommending a heat pump. Correct sizing helps the system reach and maintain a comfortable temperature efficiently, without constantly struggling or repeatedly cycling on and off.
The best results come from choosing a system that matches the size, layout, and way the space is used.

Our Approach
We Help You Get It Right The First Time
At Climate Systems, we start by understanding your home.
Room size and layout
The size and shape of the space influences how much heating or cooling is required.
Insulation and sun exposure

By assessing these factors, we can recommend a system designed to deliver the right result.

Common Questions
Heat Pump Installation FAQs
What size heat pump do I need?+
The right size depends on more than floor area. Ceiling height, insulation, glazing, sunlight, room layout, and how the space is used all affect the heating and cooling load. We assess these factors before recommending a correctly sized heat pump.
Where is the best place to install a heat pump?+
The best position allows air to circulate through the room without blowing directly onto the places where people sit or sleep. We also consider access, drainage, pipe runs, outdoor-unit airflow, noise, and the appearance of the finished installation.
Can one heat pump heat my whole house?+
Sometimes, but it depends on the home's layout, insulation, and how easily warm air can move between rooms. Open-plan areas may suit one system, while separate rooms often need a multi-room or whole-home solution.
Is a heat pump the same as air conditioning?+
In New Zealand, most residential heat pumps are reverse-cycle air conditioners. They move heat indoors during winter and reverse the process to provide cooling during summer, giving you heating and air conditioning from one system.
Should I replace an old heat pump or have it serviced?+
If the system is still suitable for the space, a professional service may restore performance and efficiency. Replacement may be the better option when the unit is unreliable, expensive to run, no longer correctly sized, or nearing the end of its useful life.
What brands of heat pumps do Climate Systems install?+
We supply and install trusted heat pump brands including Mitsubishi Electric and Fujitsu. Our recommendation is based on the needs of your home rather than simply selling a particular unit.
