As the old saying goes, too much of a good thing can be bad. This is especially true when it comes to the refrigerant in your air conditioning unit. We’re all aware that not having the proper amount of refrigerant in your air conditioner can spell major trouble. But did you know that overcharging your unit can put your entire system in jeopardy as well? An air conditioning repair expert explains why here.
The symptoms of overcharging are the same as undercharging – warm air coming through the vents. The problem with filling your air conditioner with too much refrigerant is that it won’t be able to properly switch between a gaseous and a liquid state, resulting in inefficient cooling.
Adding too much refrigerant also increases the pressure inside the air conditioner, which forces the compressor to work a lot harder than it has to. In addition, this puts tremendous strain on the entire unit, and can cause your air conditioner to wear out that much more quickly. This is why HVAC installation contractors only fill up your unit to the specified refrigerant level.
Another problem associated with overcharging is liquid refrigerant leaking into the compressor. This will cause your compressor to eventually burn out as the refrigerant mixes with the oil. When this occurs, the compressor will inevitably fail, which means that you’ll have to shell out money for a new system; this is more cost-effective than having it repaired.
To avoid overcharging your unit, make sure to only work with skilled, licensed HVAC companies.
