It had been a long day that started before dawn. Everyone needed me as I was the only one who could answer their questions. After the fireworks left the sky, vendors packed up their wares, the smell of all that food disappeared and the last piece of trash was picked up. I barely remember the drive home as I climbed into my bed. Just when I began to relax enough to sink into a much-deserved slumber, my ears pricked up, something strange was making noise in the house. Eyes closed head in my pillow, the sound got louder and louder, clearly sleep was not in my future. As I lay there trying to figure out if I it would be easier to roll out of bed or just start shooting with the gun in my nightstand, I decided I should at least look around first.

I look and listen to the noise and realize it’s a drip coming from the vent above my bed. UGH, now that I know what it is maybe now I can go to sleep after all it was like 105 in the shade with 100% humidity, of course the ac unit would be earning its keep and these drips were a nasty side effect. A few hours later I awoke drenched in sweat, it felt like I was still outside in the heat and trapped in a nigthmare. There wasn’t a choice I had to get up now. My air conditioner system wasn’t working. Oh no that chocolate bar in my pantry is going to be ruined, I can lick it from the wrapper, right? As I walk toward the kitchen I see my cat in the bathroom laying on the cold floor mouth open panting looking at me like if she could move she’d be ninja cat and I won’t make it out alive.

I go to the thermostat and see that it should be 72, but the interior temperature is reading 85, no wonder I can’t sleep and the cat wants me dead! I look at the filters and the central air conditioning system only to find that my coils are frozen. Now to figure out what happened to my ac unit.

When people refer to the coils of an air conditioning unit, they are talking about the evaporator coils. They are the component of the A/C system that transfer the heat from the inside of the home to the outside. When it freezes the evaporator, coils cannot transfer heat properly which means it gets overcooled. This overcooling cause water formation and eventually freezing. There are two reasons that coils freeze:

  • Airflow is restricted
  • Refrigerant (Freon) is low

Air conditioner repairs can still be made for this type of problem, it actually happens often. Follow the steps below to troubleshoot your air conditioning system:

  • Turn off the A/C unit at the thermostat. Don’t raise the temperature, just turn it off.
  • Check all access points, filter, return filters, vents, handlers for blockage, debris, or dirt. Replace or move anything blocked.
  • Open all register or vents to ensure that airflow is not restricted.
  • Call your local air conditioner repair professionals. If all of the above was clear and your ac unit is still frozen, then the refrigerant needs to be checked. Don’t attempt this without the help of a qualified air conditioner specialist.
