When you are in the middle of a heatwave, you become desperate to have your air conditioning working well. The mornings and nights are usually really humid and to have your AC unit work less than perfectly, is really frustrating. I couldn’t feel very much cool air coming out of the air vents and what was coming out, was tepid. The cool air was nowhere near as strong and cooling as it had been in the past. The airflow was weak and ineffectual. I swore the air vents were closed, or the air conditioning just wasn’t turned on. I had no idea what was wrong with it, but I had some serious concerns about the air conditioning unit. I was talking to a friend of mine who told me I may have a problem with my coolant. I was going to go home and open up the unit, but he told me that when it came to the coolant, it was something that should be left to a professional HVAC tech. I knew what it cost to have a professional HVAC technician do a house call, but I didn’t have a choice. I called the HVAC company and asked if they could send a technician out to look at the air conditioning unit and I told them what was going on. When the HvAC tech arrived, they did a good inspection, but I’m sure they already knew what was wrong. They found a hole in the line that goes to the coolant. After replacing the small hose, they filled up the coolant. Within five minutes, not only did I get good airflow, but my home was already cooling down.
