Refrigerant Charge

Having the correct amount of refrigerant in heat pump, air conditioners and other types of space conditioning systems is very important to their operation. Research has shown that typical undercharged refirgerant levels in HVAC systems can produce efficiency losses of 30%. Under low charge conditions, the equipment continues to run but at reduced capacity, run times are longer, extra energy consumption. This loss in performance is particularly egregious where customers may have paid a premium for a high efficiency heat pump or air conditioner, yet the efficiency benefit is not deliverd due to improper refrigerant charge.


Check the refrigerant charge. The circulating fluid in your air conditioner is a special refrigerant gas that is put in when the system is installed. If the system is overcharged or undercharged with refrigerant, it will not work properly. You may need a service contractor to check the fluid and adjust it appropriately.
