Upgraded 2 years ago to a Carrier variable speed heat pump. I went from a one speed (100% or off. They call this a two speed unit, but one of the speeds is OFF!) to a 75 speed heat pump. (25% to 100% in 1% increments) The new unit qualified for a $2000 tax credit. We are saving between $30-$35 a month in electricity. On a purely monetary method it would be many years to pay off the difference in the purchase cost between the two units, but it is much, much quieter. The prior unit was outside our bedroom and we would hear it bang and boom all night. The new one we can’t hear most of the time. Since it can operate at lower speeds it is not just quieter but is also much more efficient in dehumidifying the house. The fact that it can operate at such low speeds means it also is quietly running for longer time intervals. This doesn’t add to the electricity cost as I’ve already said it saves us money each month. Since it runs longer the air temperature is more even throughout the house whether it is cooling or heating. No more hot or cold spots. My wife’s sewing room is no longer hot and our glassed in lanai stays near the house temperature. (Sliders open) We rarely turn the mini split on anymore. As you can tell, we love our new unit. I did get a 15 year warranty with it. Let’s see I’ll be 91 when that runs out!
