Inexperienced air-con: what’s eco-friendly AC? 

At HVAC.com, our writers create options that put you in command of your HVAC system. Our product opinions and proposals are researched and backed by actual consumers and business consultants, not dictated by our companions.

With temperatures rising every decade, it’s no shock the demand for AC is rising. However at what value? 

Inexperienced air-con choices and different methods to make AC extra eco-friendly might have a optimistic affect on the environment. 

Why isn’t AC eco-friendly?

Air conditioners use a whole lot of electrical energy to function. Electrical energy manufacturing emits carbon dioxide into the ambiance. Carbon dioxide is taken into account a greenhouse fuel. And, at excessive ranges, can contribute to world warming.

Moreover, air conditioners use refrigerant. Refrigerant is a compound that removes warmth from the air because it cycles by means of the AC. Used correctly, it’s protected for the atmosphere. But when it begins leaking or is prohibited, like R22, refrigerant contaminates the ambiance and causes a warming impact. 

Is there inexperienced air-con?

At present, 100% inexperienced air-con hasn’t been developed. However some producers supply options that make AC extra environmentally pleasant.

Renewable vitality

One option to diminish the adverse environmental affect of an air conditioner is to cut back its electrical energy consumption.

Renewable vitality like photo voltaic supplies an answer. There are some photo voltaic air-con choices out there at this time. For instance, Lennox builds its SunSource line to simply combine inside a house already using photo voltaic vitality. 

HotSpot Power makes a mini break up that can maintain you cool and fully off the grid energy-wise. 

R-410A refrigerant

Most air conditioners constructed within the final 5 years make use of R-410A refrigerant. This can be a preferable choice in comparison with R-22 (Freon), which was the refrigerant of alternative throughout the business. 

R-410A (additionally referred to as Puron) is much less damaging to the atmosphere and human well being. It doesn’t hurt the ozone layer.

In the event you’re not available in the market for a brand new system, you may rent an HVAC tech to replace an older air conditioner to make use of R-410A as a substitute of R-22. Nevertheless, retrofitting an growing old unit is probably not a fascinating monetary transfer in comparison with investing in a extra energy-efficient mannequin.

Quickly, we might even see a brand new class of refrigerants referred to as A2L take over. They’re much more eco-friendly than R-410A. Plus, they’re much less poisonous. 

Evaporative cooling

Evaporative cooling is an alternative choice to a conventional air conditioner. This methodology doesn’t use refrigerant and consumes lower than half the vitality of conventional air conditioners. 

These techniques work by pulling outside air in, the place it passes over water-saturated pads. The water evaporates into the air, which causes it to chill. Then the cooler directs the cool air into your property.

An evaporative cooler could give you the results you want if you happen to stay in an space that doesn’t get too scorching and has low humidity. Since these techniques push scorching air out of your property by means of open home windows, they aren’t for all existence.

Enhanced vitality effectivity

The vitality effectivity of an air conditioner is measured utilizing the Seasonal Power Effectivity Ranking (SEER). The next quantity signifies a extra environment friendly unit. 

Most fashionable ACs have a SEER of no less than 13, however 2023 HVAC rules name for a change. The highest inexperienced air-con choices can have a SEER of round 26. Lennox claims its SL28XCV is essentially the most environment friendly AC available on the market, with a SEER of 28. 

Whereas high-SEER air conditioners are usually costlier than lower-SEER options, they may prevent cash long-term in your utility payments.

An AC with a SEER of 15 or greater can earn the ENERGY STAR certification. Buying ENERGY STAR merchandise could earn you extra rebates and tax credit. 

Ideas for inexperienced air-con

Not all of us can afford to improve our AC. And in case your present system is working simply effective, ditching it for one thing newer and greener is probably not essentially the most environmentally sound choice.

Take into account these solutions for working your present AC in a extra eco-friendly method.

• Set your AC to 78℉ in the summertime, in response to Power.gov.
• Use your thermostat to set your AC’s fan to “auto” as a substitute of “on.”

The way forward for inexperienced air-con

Trade developments and regulation adjustments counsel there’s a promising future for eco-friendly air-con. Many big-name manufacturers and unbiased researchers are closely invested in lessening the environmental affect of AC.

Some are centered on new evaporative cooling strategies. Others are innovating environmentally protected refrigerant compounds. And extra are constructing renewable vitality sources to energy HVAC techniques.

Although fully inexperienced air-con doesn’t exist at this time, the longer term seems promising.
