What to Say
Right now, we need to make unprecedented changes to ensure a sustainable and equitable society. Every extra bit of warming matters.
Eneref Institute is encouraging air conditioner companies to promote their inverter technology over their less-efficient systems.
You can also call your governing agencies across the US — and around the world — to create incentive programs to help consumers and businesses replace their inefficient systems with energy-saving inverter air conditioners. Let’s make cool rooms… And a cool earth.
- INVERTERS EFFECTIVELY REDUCE GLOBAL WARMING
A 30% improvement in air conditioning efficiency could reduce global CO2 emissions by up to 25 billion metric tons over the lifetime of the equipment, according to a 2016 US Department of Energy report. That’s the equivalent of eliminating the annual emissions of 1,550 coal-fired power plants.
- INVERTERS MINIMIZE ENERGY USE
Inverter systems ramp up to the desired temperature quickly and then hover at the ideal temperature, working like a sort of cruise control. For this reason, inverters use minimal energy compared to conventional constant-speed air conditioners, which run at full capacity. Inverter systems typically need to operate at full capacity at less than 10% of the time.
- INVERTERS NATURALLY RUN QUIETLY
Because variable speed inverters work at a lower capacity, less power is consumed, offering quieter operation. Inverter systems are not only smoother in operation and better under extreme temperatures, but they also reach the desired temperature, or set point, more quickly.
- INSTALLING CONTRACTORS CAN SAVE
Conventional air conditioner systems are often specified for the worst-case scenario — oversized, for maximum load. Because inverter technology is more precise — they burn only as much energy as needed — inverters allow contractors more flexibility in how they specify systems.
- HOW TO GET STARTED
The roadmap to more efficient residential air conditioners should begin at the local level. Call your local representative and ask about energy incentive programs for inverter-driven technology.
