Here are some quick tests you can do on a heat pump to confirm it is operating close to specs without using gauges when the coil is frost-free and the outdoor temps are 65-15. This means if it is 50 outside the suction saturation temperature should be between 25and 30 on most systems.

You can repair your R-22 system by replacing the compressor or one of the coils in the 900-2000 range or you can use this opportunity to switch over to the new refrigerant R-410a by replacing the outdoor unit condenser or heat pump and the. It is considered a near-azeotropic but is still an azeotropic refrigerant. The problem with R-22 is that it has become very scarce and thus very expensive.

Log in for more information. Use only R-410A approved service equipment. If a system has been open to the atmosphere for more than 4 hours the compressor oil must be replaced.

The suction line is where the refrigerant passes through to the different components. The proper charging method for blended refrigerants is to use a remove the change as a what. B pressurized with R-22 then leak checked.

At 50 to 70 higher pressures than R-22. With an air-cooled condenser on the roof of a building in the evaporator on the first floor recovery should first occur. Manifold sets should be 800 psig high side and 250 psig low side with 550 psig low side restart.

Some retrofitting might be required to make the changeover and if its extensive its because your system is old enough for you to consider replacing it with a more efficient model. An R-22 coil will have a TXV or fixed restrictor device that is not designed to operate properly in an R-410A system and will result in serious operational issues. Only use indoor coils approved for use on R-410A systems.
