This begins back when we bought our home in 2001. We gave very little thought to the associated technical systems. It was our first home, which was excitement enough. It had four walls and a roof. A fenced yard for Dickson T. Dog. These were the explicitly stated criteria. It came some with old appliances, an old central air conditioner and a very old gas furnace. The house was built in the early 1920’s, so it’s safe to say that everything was vintage, but we didn’t care.
The Story Begins in 2003
About a year later, the compressor in that obviously very old air conditioner failed. While repairable, it was so old that a major repair (compressor) seemed a bad idea. So, we called our preferred air conditioning vendor and arranged to have a new system installed.
It was spring and not yet too hot. We opted for a 4T American Standard system rated for 13 SEER. Pretty basic, but a leading brand, from a vendor we trusted, with a 10 year warranty. Honestly, I don’t think we even considered anything beyond a single stage unit. It was a vast improvement over the ancient, recently deceased, Kenmore system.
