"Just Notes" that may just help someone. How easy is it to do it to it?
Before anyone attempts to work on or diagnose "ANYTHING" they ;
Better know what they are doing and or have a little common sense.
Maybe have appropriate test equipment.
Maybe a knowledge of what your about to work on. Please read whole tip before using.
LINE FILTERS
Sucion line drier close to the inlet of the compressor.
Liquid line drier close to the inlet of the metering device. ( TXV )

LOSS OF HEAT ( open loop )
If there is no water running thru the system ( heat exchanger frozen water maybe )
Make sure you have water pressure and all valves and solenoid valves are open.
The solenoid valve needs to go on the discharge line.
This is keep the heat exchanger coil full of water at all times.
Scaling inside the heat pump is a problem for open loop systems.
Keeping the coil full helps to combat scaling.
Make sure all filters are clean. ( should be a screen filter on your supply water line )
Turn the thermostat to cool and the temperature down so the system runs.
Let system run for a minute or maybe two and listen or see if there is water running.
If so make sure there is a good enough water flow thu the system.

WATER PIPE NOISE
Is water running through the system even when it is not running?
Solenoid Value is stuck open?
( sometimes you can take them apart and cleen the sediment out )
Make sure to turn off the water before and after the solenoid.

CLEANING FOR PERFORMANCE
Get a little sprayer and high foaming coil cleaner from your local plumbing store.
In your return duct at your air coil cut a hole as big as you can.
Make your cuts at least 3 inches from the sides and bottom.
Also slant your cuts toward the center, so when you put it back in place it sets.
Pull out filter and put rags in bottom of filter slot to catch over flow.
Have a drop light so you can see the coil real good.
Spray cleaner from side to side into fins. ( try to spray between coils running thru fins )
Rinse coil and condensate pan real good to remove all the cleaner. ( clear water in your spayer )
Sometimes you may have to clean a second time. ( rinse real good everytime )
Don't tape so you can have access later to clean again. ( check every season )

CIRCULATING PUMPS
Spray silicon in used 3-way valves on loop lines before turning.
Before you even try to turn the older plastic 3-way valves.
Spray silicon in threads of purge position after plug is taken out.
( usually under a snap in or foam cover )
DO NOT over tighten your fittings into these plastic valves, they will crack easily.

BLOWERS
If your blower stops, delay starts, needs a little help getting rolling.
Maybe smell an electrical smell thru the registers.
"Remember that capacitors hold a charge and can hurt you."
( take an insulated screw driver and short across the terminals to discharge )
Check for a capacitor on or near your blower.
This gives the motor a little help to get rolling.
You can test these with a capacitor tester.
( Or ohm across and it will charge and reverse test leads to charge opposite direction. )
But there's also usually a fan relay in the wiring.
And there will be a contact of some sort.
You might save a little time and money ( temporally ), but a high percent of the time your blower motor will be bad also.
