How To Get The Most Out Of An AC Unit And Reduce Electricity Consumption

There is hardly a home without some sort of an AC unit. Whether it is a small, portable one, or perhaps a larger unit, every home, especially in places with warmer climates, has one. Now, these devices as we all know spend electricity and not only that - they have a bunch of other stuff that you need to keep an eye on, such as filters, cables, and other parts.

If you have bought an AC unit and immediately regretted it after your first electricity bill came in, you are not the only one. But, there are some tip and tricks you can utilize in order to keep the costs down to reasonable amounts, but still have the benefits of cooling down.

There are numerous ways you can help affect the performance of your AC unit to keep it from spending too much power, but also work better and longer. There are certain things you need to pay particular attention on when purchasing, maintaining, positioning, and using your unit.

Here are some of the things you will need to know, keep an eye on, or install in order to achieve that:

  • Programmable thermostat
  • Clean filters
  • Closed vents
  • Regular maintenance
  • Energy-efficient unit
  • AC temperature increase
  • Don’t go under 25°C
  • Ceiling fans
  • Keep the AC unit away from direct Sunlight
  • Insulation of the room

Programmable thermostat

Having a programmable thermostat utilized in your cooling system is mandatory. It is estimated that this will save up to 15% on your electricity costs because the thermostat will only engage the AC when it is needed, as your programming demands.

Clean filters

You should clean your filters or replace them at the beginning of every heat season, and keep checking them every month. Also, make sure the ducts are free of leaks, because even the smallest holes can cause you to lose up to 25% of the cool air flow.

Closed vents

Shut the ventilation shafts in rooms you rarely use so you do not cool them unnecessarily.

Regular maintenance

You must maintain your AC units regularly. Having an annual maintenance, just before the heat season begins, is an excellent way to secure it will work properly and efficiently. An efficient AC unit will work better at less energy consumption, keeping your costs down. Another useful tip is to ask your energy provider has a peak-demand rebate system or other energy-efficient rebates. Ac units lose about 5% on efficiency yearly, if you don’t have them serviced.

Energy efficient unit

When purchasing an AC unit, you should get one with a seasonal energy efficient ratio (SEER) of 13 or higher. It should also have a thermal expansion valve, which allows the unit to be much more efficient during very hot weather.

Night fan

If you have a portable fan, or a fan only option on your AC system, make sure you take advantage of cool summer nights.

AC temperature increase

The temperature setting is the main thing affecting the energy consumption of the AC unit. The higher the setting is, the lower the energy consumption, naturally. It is estimated that the 25°C temperature is the ideal temperature for having cool comfort and minimal energy consumption.

You can easily calculate the electricity saving percentage too. Let’s say that the outside temperature is 45°C, and your AC is set for 20°C. If you set it to 25°C, the energy saving will be about 20%.

Here’s how it works:    x 100 = 20% savings

It is estimated that every degree under 25°C will increase electricity consumption by 3%. This naturally goes for rooms that have good insulation.

Ceiling fans

You can use fans together with larger AC units in order to achieve energy savings and efficient work. But, if your roof is directly exposed to Sunlight, and the room with the fan is directly under that roof, do not use the ceiling fan there because it will only transfer the heat down and actually heat up your room. The AC units will have to work longer and harder to cool off your room, and you will actually increase your expenses, so keep an eye on that.

Placement of the AC unit

Whether you have an outdoor unit, a window unit, or a portable AC unit, you must take care where you place it. Never place your AC unit in a place where it will be exposed to direct sunlight, or get a lot of heat from it. If you have a window unit, place it in a window that is ideally turned to the North, or at least South. Also, do not place your AC units in cluttered spaces with limited air flow, because this will obviously make it less efficient.

Insulation of the room

This plays a very important role in cooling your room and the efficiency of your AC unit. AC units are meant for cooling rooms that are closed, or the heat entering the room is minimal. You can leave your window open during summer nights, and in a way even help out your AC system, but you should close all heat pathways during the day.

You can also take other steps for reducing the heating of your home, like: white painting the roof, putting thermal insulation on the ceiling, and using thermal insulating wallpaper for the walls. You should also keep the doors and windows close, and use curtains to repel direct Sunlight entering your home.
