With r410a units the installers must have there process dialed in tight.
R22 condenser with r410a air handler.
All of the r22 in your current system will need to be re claimed and your system will need to be charged with the new r 421a.
As of 2012 the heating ventilating and air conditioning hvac industry is in the process of changing over from ozone depleting r 22 refrigerant to environmentally friendlier r 410a refrigerant.
Newer air conditioning models are designed to be used with r 410a for reliable and more efficient operation.
The r410a is a clear winner in terms of pressure applied in the air conditioner.
The r410a has much more advanced properties than that of any r22 refrigerant.
By doing so you can keep your existing coil air handler line set and other indoor equipment.
To make a short story long r410a and r22 are refrigerants.
Oxygen and moisture contamination is the biggest killer of r410a compressors that we see today.
Can i use an r410a condenser with an r22 air handler.
Because r 410a can absorb and release more heat than r 22 your air conditioning compressor can run cooler reducing the risk of compressor burnout due to overheating.
The old r22 compressors were not so picky.
It is more effective for reducing global ozone layer depletion and also performs faster.
Though the r22 is available at a cheaper rate it is always better to use the r410a.
R410a is a higher pressure system and r22 is a lower pressure system.
