We have all heard the myth: If your A/C is not working well
, all you need is a little more freon. However the myth of refrigerant being the be all end all of fixing air conditioning units. Adding refrigerant does not necessarily mean your air conditioning is going to work better. Some Denver HVAC contractors may try to trick you and charge an hour of labor and supplies for no fix. The only time additional refrigerant will help your evaporator coil is working below freezing.
The unit must have a carefully balanced charge. Only an authorized Colorado air con technician should add refrigerant because the best balance is a must-have. Refrigerant doesn't burn up. It doesn't have to be replaced unless there's a leak in as it is in a loop system.
If your unit does have a refrigerant leak nevertheless it is simple to diagnose. The A C unit will cool for one or two hours then stop. If the refrigerant coils freeze within the air handling unit this is an undoubted sign you need air con repair . Ice buildup blocks airflow over the coil. Low refrigerant causes the unit to operate below freezing and draw moisture out of the air, forming ice. Freezing ice isn't like freezing air.
If you have a refrigerant leak, you have to have it fixed. Dribbling refrigerant is a jeopardy to folks and the environment. State law asserts that Denver air-con corporations fix all unsafe refrigerant leaks.
Some refrigerants are ozone and world warming agonists. A low charge also wounds the potency of the air-conditioning unit. This leads to A / C compressors to run above their endorsed range leading to eventual replacement. Freon is also linked to the oiling in some compressors, which could cause the compressor to seize from shortage of lubricating.
Because the air conditioning element is a closed loop, refrigerant should only be added in the case of a leak. Residential units use a R-22 coolant. Prices are rising as R-22 is fazed out because of its ozone depleting properties. Phase out begins this year and is to be completed by 2020.
Call our Colorado HVAC contractor and see what they require payment for R-22 or if they have any replacement refrigerant available. The HVAC tech should find the leak when recharging an AC system. An authorized HVAC system should not have to be refilled several times a year. A productive system should lower the temperature around twenty degrees.
