Determining the best heating and ac option for your home depends on a variety of factors, including the size of your home, your budget, your energy efficiency goals, and your lifestyle.  The larger your home, the more powerful the heating and cooling system you will need to be to keep it comfortable.  Some systems may have higher upfront costs but may save you money in the long run due to their energy efficiency. Ultimately, the best system for your home will depend on your individual needs and preferences. We offer all customers a free in-home consult with an accredited installer to discuss all your options.

 Keeping your heat pump clean is key to getting the most out of it — better efficiency, lower power bills, and a longer lifespan.

Here are 5 simple ways to keep your heat pump running smoothly in Christchurch’s changing seasons:

1. Clean or replace the air filters regularly – depending on usage.
    
2. Keep the outdoor unit clear of leaves, grass, and debris – especially after storms or mowing.
    
3. Clean the indoor and outdoor coils – refer to your manufacturer’s guide, or book a professional to handle it safely.
    
4. Check the condensate drain – make sure it's not blocked, especially in humid conditions.
    
5. Schedule annual servicing and cleaning with an accredited technician – we recommend doing this before winter kicks in to get ahead of the rush.

In general, the most energy-efficient temperature range for heating with a heat pump is between 18-20°C.  You may want to adjust the temperature based on your comfort level and the specific conditions in your home. Generally it is more energy-efficient to use your heat pump to maintain a consistent temperature throughout the day and night, rather than turning it off and on repeatedly. 

When considering buying a second hand heat pump, there are several pros and cons to consider. It may be a good option if you are budget conscious and willing to take on some maintenance and repair costs, but it may not be the best choice if you are looking for a long-term, reliable heating and cooling solution. You must be aware that second hand heat pumps aren't covered by manufacturer's warranty's and guarantees and it can be more difficult to find replacement parts or matching components if it's an older model. Please contact us directly for professional advice and if our install only service is right for you.

If you’re comparing heat pump quotes, you’ve probably noticed a wide range of prices. But price alone won’t tell you whether you’re making a smart investment. Here’s what really matters:

1. Performance and efficency. The right size and model make all the difference. A heat pump that’s too small will struggle to heat your space, working overtime and increasing energy costs. One that’s too big may short cycle, causing uneven temperatures and wasted power.

2. Installation quality. Even the best heat pump won’t perform well if it’s installed incorrectly. A skilled installer ensures your system runs efficiently, lasts longer, and keeps your home comfortable.

3. Long term investment. Beyond the initial price, consider servicing, warranties, and aftercare. Will your installer be there when you need support? Do they back their work? A heat pump is a long-term investment—so it pays to choose a team you can trust.

We install high-quality systems from trusted brands like Mitsubishi Electric, Fujitsu, and Daikin—ensuring performance, not just affordability. Our accredited installers guarantee expert workmanship, so your heat pump delivers comfort and efficiency for years to come.

The operating costs of a heat pump depend on several factors, including: climate, size, efficiency rating, electricity rates and maintenance.  An undersized or oversized heat pump can result in higher operating costs. Do you save money with a heat pump? Compared to traditional heating systems that burn fuel to generate heat, heat pumps are more energy-efficient because they move heat from the air or ground to heat or cool a building. This means they can provide the same amount of heating or cooling with less energy consumption and cost. 

All new heat pumps installed by Alexar come with a 5 year manufacturers warranty. It's important to note that the lifespan of a heat pump can be affected by factors such as the climate in which it operates, how often it's used, and whether it's been properly installed and maintained. Regular maintenance can help extend the lifespan of a heat pump. Additionally, working with a qualified installer can help ensure that it's properly cared for and can last as long as possible. 

Under no circumstances should you try to troubleshoot or repair your residential electrical on your own. You should call an electrician whenever you have an electrical problem, both for your personal safety and so that your home's electrical system remains up to code.
