Have you heard old people lament that things aren't made as well as they used to be made? I guess I'm an old person now because I've taken to saying that.
When we moved into this house, it was two years old. The heat pump was a Carrier brand. It served us well for a long time before we had it serviced. It was about 21 years old or so when we had to have some points replaced. Not too long after that, a leak developed, and we had to replace the unit. I assumed the replacement unit would be similar. I was very disappointed to find out that the Goodman that was installed is a much larger and noisier unit. Then, only a year after it was installed, it began acting strangely. January, we had the highest electric bill we've had since we've lived here. What a bummer! Folks in the know tell me that the Copeland compressor used in the Goodman unit has some sort of additive which is supposed to keep the coils from rusting, but when the additive comes in contact with the Freon, a sludge is formed which clogs the piston. Darling son cleaned the piston with a pin, and so far that seems to have helped. I'm told there is a solvent that can be used in the unit to prevent the sludge. It seems as if every solution causes yet another problem, so who knows what the ramifications of adding the solvent are.
A few years ago, someone who thought he knew something said that replacing an old unit (even though it was still working!) with a newer, more efficient unit would save money in the long run by reducing the power bill. What a joke! I'm hearing that the newer units aren't lasting as long, either.
I admire folks who have the know-how to "get off the grid."
