R22 pressure chart for Lennox heat pump

This is a useful chart to have. It shows what pressures are suggested to be at at different temperatures. It will also work for air conditioners if you use the top half. If your a/c is old or dirty these pressures won't be exact but close enough. This is for R22 freon units only.

 What pressure should my heat pump run on. Mcdonough furnace repair Henry county heating and cooling. in the cooling mode what should my a/c pressure be? 


  1. Do not use a R22 substitute only put freon into your system. Many manufacturers will void your warranty if you use Iceon

  2. I think the R on my keyboard sticks or skips or something I always miss 1

  3. If you have bad air flow a dirty filter a dirty coil or a dirty a/c these pressures will be off. This chart should be close enough for most residential brands of air conditioners and heat pumps.
