The Ultimate Guide to Keeping your AC Bill Low This Summer

With another heat record-setting NZ summer looking to be on the way, many of us will be looking forward to the good weather, summer BBQs with friends and family, and perhaps some time at the beach. However, we all know what a hot and uncomfortable house can do to spoil a hot summer’s day, leaving you feeling more ‘hot and bothered’ than ‘summer fun’. Although many people associate heat pumps with winter time, with a Daikin split system air conditioner you can enjoy the best of both worlds: heating in winter and cooling in summer, giving you a total climate solution for your home and a cool and comfortable oasis on those sticky summer days.

Of course, during peak summer season, your air conditioning bill could climb without you realising as energy consumption rises. Here are some simple but effective tips to keep your AC bill down without sacrificing your comfortable indoor environment.

These tips will help you keep cool when the bills come rolling in.

1. Turn off at night, and save while you sleep

This money-saving tip is as clear as night and day! Keep your air conditioning on during the day, and off at night. The reasoning is simple. Firstly, the evening air is naturally cooler, so you can take advantage of that by turning off the air conditioning and opening a window. You may even get a gentle breeze to cool things down.

If you do find a welcome breeze, open windows or doors on both sides of your house to allow it to flow through.

Secondly, for comfortable sleeping, your body simply doesn’t need your air conditioner to run at the same temperature as it does during the day. So, with your air conditioner off, you can enjoy some nocturnal energy savings and sweet dreams.

2. Thermostats and timers - set and save

When it comes to energy consumption and reducing your air conditioning bill over summer, every degree matters!

One of the best ways to save energy is to take care when setting the thermostat temperature. Preventing your unit from working too hard by raising the temperature slightly can pay off while keeping you in a comfortably cool temperature range-even setting your air conditioning unit one degree warmer than you normally world can cut costs by up to 10%. As a rule, try not to set the thermostat less than 8 degrees below the outdoor temperature (so if it’s 30 outside, aim for 22 or 23 degrees Celsius inside).

To really help reduce your energy bill, consider a thermostat with a built-in timer, so you’re not only setting the temperature, but setting the hours of operation for maximum energy efficiency. It makes sense to have a system that does it for you automatically, so you can set, and forget. And save of course.

3. Get shady and shut out the sun

Shade, shade, shade. However you can get it, grab it, and it will help your home stay cooler. Therefore, your air conditioning unit won’t have to work so hard, and your energy bill will be reduced. It’s simple. During a hot Kiwi summer, you can’t turn down the sun, but you can add some shade to turn down the heat.

The first way to get shady is to keep blinds, curtains, drapes and awnings drawn and closed. Whether it’s Venetian blinds, roller blinds, plantation shutters or lined curtains, keep that beautiful sunshine outside where it belongs. For sun-facing windows, light-coloured backings for blinds and curtains will help deflect sun heat too.

By closing windows, blinds, shutters or drapes, you’ll be keeping the hot air and the sun’s rays out, so your air conditioning doesn’t have to run all the time to maintain the optimal temperature. Heat absorption can be drastically reduced if your windows have a strong line of defence. Even tinted windows can stop some of the sun’s heat coming into your air conditioned sanctuary, and your unit won’t have to work so hard.

Want some more ways to throw shade and reduce air conditioning bills? Consider Mother Nature’s original shade maker – trees. Plant trees, vines or shrubs that can add a defensive line of shade to the house – consider the walls and roof as well as the windows.

4. Turn off those heat-emitting culprits

The television, the computer, the printer, the lamp in the corner, the kitchen oven… all of these household essentials generate bucketloads of heat and will be forcing your air conditioner to work harder to keep the temperature under control. Turn them off and you’ll save money on your air conditioning energy consumption straight away!

What can you turn off? Can you turn off lights in unused areas of your home?

Are you game to unplug? Can you turn off the television or any other appliances? Those tablets, computers and printers emit a lot of heat that can make your air conditioner work harder. Who knows, it might even help bring back the art of conversation (or perhaps cause a family mutiny!)

Why not try cooking the dinner on the BBQ outside, or enjoy a lovely salad that requires no cooking at all? Your indoor stove can really heat up your living space and add to your air conditioning bill.

So if you want to keep your energy consumption and air conditioning bill down, think about al fresco food preparation. Who doesn’t love a sausage or a steak cooked on the BBQ in Summertime? And if it keeps your house cooler, all the better.

5. Keeping it clean to keep costs down

Here’s one more awesome tip to reduce your air conditioning bill over summer. Ensure your air conditioning unit is regularly maintained and that the filter is either replaced or cleaned to maintain optimum efficiency. A dirty filter makes any air conditioning unit work harder, meaning more electricity and higher energy costs!

Here’s to a long hot summer, and keeping cool when the bills come in.
