Can A Portable Air Conditioner Be Low On Coolant?
Mine is sucking hot air out, and pushing some slightly cool air in, but... not cool enough. Does that mean it's low on coolant?
Answer:
You mean refrigerant, and yes it probably needs a recharge. Good luck finding someone to do it though. Maybe a backyard auto mechanic, or an HVAC guy with the equipment who does side work. To get a professional HVAC company, it would probably be cheaper to buy a new portable unit. Yes, it is most likely low on refrigerant. Unfortunately, there aren't many professionals around that can recharge them. If you do some searching around, you may be able to find a kit to recharge it yourself. You might just want to save yourself the trouble and buy a new unit. Air conditioners are sealed systems. If there is a leak, the gas will leak out and you won't get any cooling. Are the coils and filter clean? If the unit cannot absorb heat from the room, it won't give you cool air. Also check the vent/fresh air lever. Package air conditioners only last a few years, then you replace them. It costs more in labor to fix than a new unit. They are not designed/built to be repaired. The most you can do is clean them. When they stop removing the heat, get a new one.
