> Installation isn't cheap. Dandelion estimates the cost at around $20,000, depending on home size and state and federal incentives. But the company notes that consumers are likely to save about 20 percent annually on the cost of home heating and cooling. Are they aiming at regular home owners? Our heating/cooling is ~ $2.4k/year - about $200/month. Fluctuates - summertime is sometimes higher, winter can bring high heating months, but our electric bill is often under $100 for the spring months, so ... it evens out. This would mean a ... $500 savings per year? $40/month? Are other people paying much much higher heating/cooling costs than I am, and this would make sense?
