There have been numerous rumors circulating throughout the years about what would happen to refrigerant and when it would happen. We have lived through a roller coaster of prices with not only R-22, but with R-410A as well. However, it is important to keep in mind that the value of anything in the world is only what you can find someone willing to pay for it. So, here we are in 2019, and I am not sure we have any better grasp on where we are headed than we did nearly ten years ago.

Without our trusty defrost cycle in these conditions our heat pump would quickly begin to look like Frosty the Snowman…minus the jolly part. There’s nothing jolly about a broken heat pump.
The defrost cycle is what allows for our heat pumps to continue efficient heating operation in cold weather. However, the actual operation of the defrost cycle is often not understood as well as desired. This leads to improper settings as well as misdiagnosis. Let’s dig into the basic concept of a heat pump operating in heat and the defrost cycle that protects it.
