What is the most efficient heating and cooling system?

It comes down to some types of AC systems and how you use it.

1. Reverse cycle air conditioning systems

Reverse cycle air conditioning units are the most efficient purchases as they provide not only cooling but also heating capabilities.

According to the Department of Industry, Science, Energy and Resources these units have an efficiency level of 300-600%. A 100% efficiency level means that one unit of energy creates one unit of heating/cooling. This means that just one unit of energy within a reverse cycle air conditioning units can create between three and six times as much in heating or cooling. Some products have even been known to reach efficiency levels of up to 1000%.

2. Refer to the Energy Rating Label and Zoned Energy Rating Label

In order to ensure that you are getting the most energy-efficient unit possible, as well as one that best fits your space, there are a number of steps you can take.

One of the most important of these is to refer to the energy rating label and the zoned energy rating label to ensure that it is the correct option for you.

An example of Energy Rating Label you can come across while purchasing reverse cycle system

The Energy Rating Label shows the energy performance of the heating/cooling unit in question, giving you an idea of how efficient it will be and how much it will cost to run.

The Zoned Energy Rating Label takes into account the location of the unit, providing enhanced information with regards to the most efficient position in which to have your unit installed within the home.

3. Consider the load that suits your space

It is vitally important that you research the unit in question before purchasing and installing. There are a number of different devices on the market, many of which target different consumers, locations, and benefits. Look into each product, pick the features that are most important to you, ask questions, and make sure that it is ideally suited to your apartment, room, house, or office.

For example, you can ask any of the following questions:

  • Is this unit designed for use within a small or large area?
  • Is this device cost-efficient for use within a bedroom?
  • Does this unit provide both heating and cooling?
  • Does this product come with a warranty – if so, how long?
  • After all, the last thing you want to do is have a unit designed for huge office spaces installed within your small bedroom.

Provided you properly use the units and get regular maintenance

Beyond the above points regarding the purchase of the unit, your heating and cooling system’s efficiency comes down to how you use it.

Remember, these are machines, so have it serviced on a regular basis to ensure that there are no maintenance issues.

A serious problem may severely hinder the performance of the unit, thus costing you more money and providing you with lesser results. Even a small issue can become severe if left untreated, learn to see the signs your AC needs servicing.

In terms of maintaining the unit yourself, you should be keeping it as clean as you can, including the filters, to ensure that it is always working at its optimum level. Not only this, but regular cleaning will also cut down on the germs, dust, and bacteria being spread around your room.

Why stopping at your air conditioning system?

In the modern-day and age, it is more important than ever to ensure that your home is ‘smart’. What we mean by this is designing a home that is as renewable as possible, self-sustainable and can be automated with timers, so you source energy from renewables energy and consume energy efficiently.

For example, you can look into investing in any of the following renewable energy sources for your home:

  • Rooftop solar panels
  • Miniature wind turbines
  • Solar oven
  • Hydropower
  • Solar water heating
  • Solar air conditioning
  • Tesla powerwall
  • Tubular skylights
  • Geothermic energy
  • Biomass
