Eco cooling – sustainable air conditioning for your home

Searching for eco cooling solutions? Keeping the home in the right temperature is definitely an energy-intensive process, and never as environmentally friendly as you’d want it to be, nor as kind in your pocket.

Air conditioning units really are a popular method to awesome your house, and you will find modern versions that may keep interiors in a enjoyable temperature with less energy use. But there are many other options, too, that can help you go greener without having to sacrifice comfort.

Keep in mind there are measures you need to decide to try keep your heat from home prior to deciding around the most eco-friendly cooling option. ‘Typically, sealing and insulating attics, basement walls and floors (ie, above unheated spaces, like a garage or crawl space), and around exterior home windows, doorways and walls would be the most important points,’ states Steve Dunn, Technology Manager for Home Performance with Energy Star. ‘Homeowners may also reducing cooling load by way of exterior shading and window attachments, for example shades, blinds, solar screens and applied solar films.’

1. Enhance The ECO CREDENTIALS Of The Ac

Some 75 % of homes in america have air conditioning units, based on Money Saver, work of america United states doe that gives energy-efficiency and alternative energy information to consumers. Consequently, the unit are costing homeowners as many as about $29 billion yearly, work states.

‘While there’s no specific age when ever a method ought to be replaced, the normal lifespan of residential method is between 15 and twenty years systems in extreme climates, however, might have lifespans nearer to ten years,’ states Steve Dunn. Swapping from your older ac to some modern high quality unit using the Energy Star label can help to eliminate energy use and cut costs. The endorsement shows products meet strict energy-efficiency guidelines set through the US Ecological Protection Agency.

Keep in mind that the central ac needs a blower motor and that’s generally a part of a furnace. For that ac to achieve its rated efficiency it shouldn’t link for an older furnace – especially one over fifteen years old – and blower motor. Quite simply, for any greener home, switch the home heating, too.

Room air conditioning units, meanwhile, ought to always be correctly sized to save lots of energy. You are able to figure out which room ac is required using the Energy Star step-by-step guide.

Regular upkeep of an ac is important to help keep it functioning efficiently. The filter ought to be cleaned or replaced routinely to help keep energy consumption lower. The evaporator coil ought to be checked each year, and cleaned as necessary. Drain channels may benefit from the getting a stiff wire undergone these to prevent them blocking up. And when the fins on evaporator and condenser coils become bent, obtain a fin comb to revive them.

Reside in a damp climate? ‘Efficiently supplying cooling in damp climates involves much of the identical strategies as other regions, however with focus on humidity and moisture control in your home,’ states Steve Dunn.

‘In very damp climates, the ac alone may be unable to remove enough latent heat to help keep relative humidity below 60 percent,’ he explains. ‘In such cases, supplemental dehumidification and humidity controls can be included to the Heating and cooling system.’


Natural ventilation might be enough to maintain your home awesome, with respect to the climate – although other solutions might need to be added in (see below) – and it is an environmentally friendly solution. Ventilate the home during the night by opening home windows to allow outdoors in and heated air out. Natural ventilation ought to always be coupled with strategies that keep heat away from home for example insulation, landscaping that produces shade for that house, and keeping doorways and home windows closed and pulling lower shades on hot days.

You can include in options for example ceiling and window fans plus free standing fans as necessary. These use relatively little electricity, based on Money Saver. A ceiling fan is the greatest choice for creating a room feel awesome, and may also be coupled with ac because it will help you to enhance the thermostat, saving energy.

You may need a whole home fan if your house is large, and one of these simple may be used rather of the ac for most of the season in many climates. It should be coupled with ceiling along with other fans for max comfort, however.

An entire house fan functions by getting in air through open home windows and it has an exhaust with the attic room and roof. Professional installation is suggested. Be careful, too. ‘Open home windows at home to avoid a effective and concentrated suction in a single. If enough ventilation isn’t provided, the fans may cause a backdraft inside your furnace, hot water heater or gas-fired dryer, pulling combustion products for example deadly carbon monoxide into your living area,’ warns Money Saver.


If you reside somewhere with low humidity, an evaporative – or swamp – cooler is definitely an effective and efficient choice, and for that reason a far more environmentally friendly method to keep your temperature in your house comfortable. Actually, one of these simple uses around one fourth from the energy of the central ac, based on Money Saver.

An evaporative cooler passes hot outside air over water-saturated pads so its temperature drops. An admirer blows this awesome air in to the house, and warmer air is pressed out with the home windows, which have to be partly open. Rather of blowing the environment right into a central area of the house, it may be linked to ductwork to funnel the environment to individual rooms. The second product is required for a sizable house, even though the former could suit a smaller sized home by having an open layout.

Keep in mind that evaporative coolers need regular maintenance that exceeds those of air conditioning units. Additionally they use water, which can be a problem where you reside.

4. Make Use Of A Electric

If you are thinking about switching to some electric being an eco heating option, you will be glad to understand that it may offer energy-efficient cooling for your household. Both air source and geothermal power heat pumps can awesome and also heat a house.

‘Ground source heat pumps tend to be more energy-efficient than traditional central AC systems,’ states Steve Dunn. ‘They can be employed in any climate, due to the earth’s constant temperature subterranean (varying from 45º to 75º F based on location). GHPs can reduce energy bills by as much as 65 percent when compared with traditional Heating and cooling units.’

When you are picking out a electric, consider the Energy Guide label, which will highlight the cooling efficiency, given like a periodic energy-efficiency ratio (SEER). This is actually the total heat removed within the annual cooling season in British thermal units (Btu) divided through the total electrical power consumed through the electric throughout the same season in watt-hrs.
