How to Tell If Your Central Air Conditioning Unit is Low on Freon
Your central air conditioner and refrigerator are pretty much cousins. Both appliances work the same way: they suck air in and cool it down by moving the heat from the sucked air to the refrigerant. This substance, colloquially known as “Freon”, doesn’t technically run out per se, but there are signs that indicate the need for a refill or, as air conditioning technicians in Edmonton call it, a “recharge”. Central air conditioning systems use refrigerant that can technically last a lifetime, but certain circumstances can cause issues with the coolant supply. Accidental damage, natural wear and tear, and contaminants are some of the most common reasons. One of the first things you should check for signs is the thermostat—sometimes, units simply need to be reset electronically and may not actually need a recharge at all1.
