My contractor ran the unit for 15 mins before I realized he did not flush the lines at all. Could this have permanently damaged the new R410 condenser and if so can it be fixed?

hvac - Replace evaporator coils when replacing R22 condenser ...If you are replacing the A/C system with 410A refrigerant then you will have to replace the indoor coil and refrigeration lines as well due to the suction lines on the 410A units are larger. They still make HCFC22 refrigerant units that would allow you to replace only the outdoor condensing unit.
Can R22 coil be used with R410-A condensor? | Yahoo AnswersTechnically speaking, an R-22 coil CAN be used for R-410a IF: 1. The coil is properly flushed 2. The metering device is changed to one for 410a 3. The coil is rated for 235 psig Since keeping the old coil is more work and worry than it's worth, you're just better off changing it to a proper R-410a evap.
How to properly charge an air conditioning systemThe condenser and the evaporator must be clean. The blower must be capable of moving the correct amount of air. Visual inspection of the evaporator can be aided with the use of a video scope by removing the high limit of most furnaces and fishing the shaft up through the heat exchanger to the bottom side of the coil. Set the required airflow.
What Is the Difference Between an R410 and an R22 Compressor ...What Is the Difference Between an R410 and an R22 Compressor?. Air conditioners use different types of refrigerants, which are called R-22 or R-410A. The type of air compressors used for each type of refrigerant are also different.

410A coils — Heating Help: The WallIt's my opinion that the line set as well as the coil and condenser be replaced when going with a R410 system when the original system was a R22. I say this because of the incompatibility of the oils (POE vs mineral oil). I have lost work because of this stand, I'll admit.
The Professor: Condensing Temperatures and Condensing Splits ...Condensing temperatures often give service technicians valuable hints as to what the problem may be within a refrigeration system. In fact, most service technicians would rather troubleshoot the refrigeration system's high side than the system's low side. This is because almost all of the heat ...
Condenser using R22 can be retrofit with coil using R410A?The condenser using R22 can not be retrofit with coil using R410A? You cannot use R-410A refrigerant in a R-22 unit. No retrofit is possible due to design pressure limitations. But you can use a R-410A inside coil on a R-22 outside unit since the R-410A coil is rated for a higher pressure operation than R-22 will expose it to.
Converting an R22 A-Coil To a Water to Air Coil?Converting an R22 A-Coil To a Water to Air Coil A friend of mine has a water to water geothermal unit for heating his home. He wants to use this same unit for cooling the house. Looking at water to air coils the prices are quite steep compared to the standard run of the mill A-Coils.

R22-410 conversion questions. | Hvac Pro ForumsA very old YORK 7.5 ton condenser is having a hard time.The fan keeps eating fan blades because the spider bracket is old, weak, rusted, welds broken and it is no longer available. This beast is 35 years old and ready for retirement. This is attached to a VERY old McQuay air handler, a beast of a unit and we don't want to replace the evap coil.
Any coils compatible with both R-22 and R-410? | This Old HouseKevin, most if not all your evaporator coils are compatible with either R-22 or R410a. The problem with mixing them up is two-fold. First of all, if you are replacing an outdoor unit (formerly R22) with a new 410a unit, and keeping the same indoor coil (as long as it is a match) you have to be able to eliminate (in its entirity!) the residual R22 that is in the system.
What components need to be changed when upgrading from R22 to ...The evaporator cooling coil in the house if properly sized and cleaned may work with r410 but it is difficult to get all the mineral oil out of the system, changing the evaporator if separate from the heating side would be the safest along with the suction and pressure lines to the compressor and condensing coil outside.

Guidelines For Troubleshooting R-410A SystemsThe big push is on to replace R-22 unitary air conditioners and heat pumps, and it looks like the industry has really and truly decided that R-410A systems are "it.” This article offers an overview of some of the issues related to R-22 and -410A in the field: operating pressure differences, oil characteristics, and temperature glide.
410A vs R22 — Heating Help: The WallPutting the efficiency issue aside for a moment, let's take a look at the operating pressures. R-410a operates at pressures that are about 70% greater than those of R-22. So, to get your 40-degreee coil on an R-22 system, your low side pressure will be about 68.5 psig. On an R-410a system, however, the low side pressure will be about 118 psig.
