Residential Air Conditioner Costs: Energy Usage Vs ComfortAngelique Laaks
Weighing climate control comfort against residential air-conditioner costs may seem a cruel exercise. That’s because most of us are still indoctrinated with old ideas about how much electricity air-conditioners use to operate. Our out-of-date- views are understandable if we haven’t recently examined just how effective energy-saving technologies have worked to bring climate control within our purse strings.
It’s time to set the record straight. Our little journey into the brave new world of smart aircon might open the way for us to accommodate residential air-conditioner costs. Our friends and family will benefit from the pure indoor air that accrues from spending more time in conditioned air as opposed to polluted outdoor air.
Purchasing Residential Air Conditioner Costs
It is said that the average reverse-cycle air conditioner costs around R 3.61 per hour to run – taking for granted that the unit is right for the room size. This translates into about R 3.60- R 5.00 for an average 36 m2 room. In the case of a 70m2 area, the cost would be between R 19.00 and R14.00 per hour.
Hidden Residential Air Conditioning Costs
The first thing to look out for is a company that offers competitive year-round costs, as opposed to those whose prices fluctuate with seasonal change. With a work ethos like that, we can be sure we are being looked after and not hurriedly ticked off the list of the many grabbing at a ‘limited special’. Once we’re sure we are with a reputable group, here are the key mitigating factors to weigh:
Size Matters in Residential Air Conditioner Costs
A unit which is too small for the size of the room will use way more electricity than is necessary. Plus, that additional workload will shorten its lifespan. Conversely, paying for a higher capacity unit when it’s not required doesn’t make sense either – you are paying more for the unit and more to operate it.
Models Matter in Home Aircon Units
Aircon models are graded by the IBBE (Indian Bureau of Energy Efficiency). So, before you ask the price, first ask what its star rating is. A 5-star rating is highly energy-efficient and will consume less power than a 4, 3 or 2-star model.
Type Matters in Residential Air-Conditioner Costs
Individual units may be fine for two or even three rooms, but despite initial installation outlay, a central ducted system will use far less energy – and it cools the whole house besides. Costs incurred initially are well recouped over the long and uncomplicated lifespan of central aircon systems.
Tips for Energy Saving While Keeping Comfortable Indoor Climates
It is nothing short of deeply rewarding to see how modern technological innovation in residential air-conditioning affects costs. We really do not have to sacrifice comfort to save costs. There’ll be at least a 40% saving on running costs with the new technology in residential air-conditioning compared to older air conditioning units.
Instead of hanging on to our antiquated systems, the first saving could be to invest in new air conditioning for a start.
Even with new installations here are some street-wise tips families can implement to reduce the amount of cooling done by residential air-conditioners, such as:
- Limiting outdoor air and warmth will have a marked effect on hidden residential air-conditioning costs – keep doors and windows closed so that as little warm, moist outdoor air as possible enters the room. Closing curtains and blinds block the sun’s heat thus reducing the aircon’s workload.
- Roof and exterior wall heat have a major bearing on the temperature of a house. Paint the roof with reflective paint to minimise solar absorption and paint the outer walls with a light colour to reflect sunlight as much as possible.
- Trees shading a home are a great boon and will ensure your home never bakes in the midday sun, which only heats it up and makes any residential air conditioner work harder.
- The ideal temp setting is 22 degrees C. for every degree set above 22, the air-con will use 3-4% less power. So if you’re ok with 23, you’ll be that much better off, especially if you’re running the unit all day.
- Moving the cooled air with fans – don’t panic, they use 25 times less energy than any aircon, and they keep the cool air well-circulated which means the aircon need not have to run on as high a setting.
- Free-flowing air will keep the room cooler, so if any objects are blocking the air being pumped out of your cooling unit, it is best we remove them.
- Heat-generating equipment such as lamps, computers, TVs, modems etc need to be away from the AC’s thermostat. It will ‘read’ the nearby heat and make it work to reach the setting longer than it needs to.
- Maintaining the filter alone saves both costs and unit damage. Regularly cleaned filters help reduce residential air conditioning running costs because the unit does not have to work so hard to reach the required temperature setting.
- Outdoor coils should likewise be cleaned regularly as they become easily clogged with dust and grime.
- Expert residential air conditioner maintenance professionals should be calling annually to check the air conditioner and service it. Make sure the technician measures in amperes the total energy drawn by the unit, which indicated how much current is being taken up. The higher the amps, the more energy is being used.
All things considered, this is really good news for the residential air conditioner cost debate. Be assured that TOSHIBA – world leaders in energy-efficient innovation – can assist you with the best air conditioning system for your home.
