Our Old Central Air System Still Had a Lot of Life in It


It can get pretty hot here in Sacramento during the summer. I thought that I would enjoy the heat when I first moved here. For the most part, I do, but there are days where it is just too humid to even want to step outside. The house my wife and I had bought has central air conditioning, and it feels so refreshing on those humid days. When it stopped blowing out cold air a few months ago, I knew I needed to get a company that does appliance repair in Sacramento to come out and take a look at it.

I did not want to try and fix it myself because I figured it was going to be long and involved. I wasn’t sure I even had the tools to do it. My wife joked that I might not have the knowledge to do it either, but she could be right with that! Rather than mess with something that I could possibly make worse, I just hired a serviceman to come out and take a look at it. I just hoped that it was going to be easy to fix, because I was not prepared at the time to purchase a new unit altogether.

The refrigerant was a little low. Not enough to shut off the compressor, but enough that the nice cold air was turning to warm air blowing out of the vents. The technician used a refrigerant sniffer to check for leaks, and there was no sign of any. The system is about 20 years old, and it has not been serviced regularly. The technician topped off the refrigerant to the specified amount, but he knew that dirty coils outside were probably the major cause of the problem as the heat was not being carried away. He used an acid solution and our garden hose to clean it, and the cold air came back even colder than what it was before.
