I have been looking for information specific to inspecting heat pumps. I have conflicting information/advice on the procedures such as:
Test AC only when the temperature is above 65 Degrees (heat pump)
Do Not test heat when the AC has been running within X hours
Is their a good link that spells this type of information out(heat pump specific)? I would like to have a fall back because I have been confronted with these items by both owners and sellers etc.
I have been looking through various information and have not found what I am looking for.

Paul,
Thanks for the response, however I am looking for more specific as applicable to do and don'ts. Some units for example have protective thermostats on the exterior preventing functions etc.
Any other input?

Michael,
It is a good assumption that if the AC works, the heat works. They both use the same condenser unit, air handler, thermostat...etc.
If you have found good working conditions with the AC unit it is safe to inform the clients they both are using the same components therefore if one works the other works. It is not advisable to use both right after the other.
While I state in the report I do not test them when the temperature falls below 65 degrees turn on the heater and make sure it functions. Again, if one works they both work.

Joe,
That is the same position I have taken, however I have been challenged on the back up heat and the diverter valve etc.
I was using this as a fishing expedition hoped that I had missed a web site or a specific directive on the testing / inspection. I believe it is Ream that uses exterior thermostat as well as another device that prevents the ability to change from heat to cooling rapidly.
Thanks for your input.
