First off, I thank Willis Haviland Carrier for inventing air conditioning in 1902.
Our central air conditioning system is working again. The repair guys came Friday afternoon. They found two problems:
- We were out of freon coolant, or specifically, “Refrigerant 22”. To replace, it cost us $4 per ounce, and $270 for replacing 4 lbs. of the stuff.
- Our air filter was filthy, which I hadn’t been replaced in years, as I didn’t know how or where. If I had a manual……
So yeah, whatever. More refrigerant, replaced air filter (which I ran out and bought from Home Depot), labor, and taxes. The house is comfortable again.
