Heating and Air Conditioning questions, answered by experts

AC evaporator coils should be cleaned at least once per year to keep your unit in good condition. For optimal performance, consider cleaning them twice a year—once before and once after the main cooling season. More frequent cleanings may be necessary for older systems, units with performance issues, or those in climates with high levels of humidity, dust, and dirt.

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

Both evaporator coils and condenser coils are recyclable and contain valuable, sellable metals such as copper and aluminum. Not only is it more earth-friendly to take them to a local metal recycling facility, but you can also trade them in for cash. Also, once the coils are removed from the system, they won’t have any traces of refrigerant, so you won’t have to arrange for recycling Freon or R-410A unless you’re disposing of the entire AC system.

A dual evaporator coil is a specific design that allows the AC system to cool different compartments at different levels. It’s usually seen in refrigerators and similar appliances, but not in whole-house air conditioning systems. Talk with your AC technician about the best uses for a dual evaporator coil.

The average life span of an HVAC system is 15 to 20 years. Even if your old air conditioner is still functional, it isn't as energy-efficient as a newer system (especially one with an Energy Star designation). Older HVAC systems aren't as efficient, and the 10-year mark is when you should start making full system replacement plans. Twenty years in, that plan should be well underway rather than waiting for the unit to die.
