Tip & How-To about Heating & Cooling

Your Air Conditioner's Condenser

Look for crimping in both refrigerant lines. They are most vulnerable where they leave the condensing unit and where they go through your exterior wall.The larger tube should be cold and insulated.

Check that the insulation is in good condition, without wear or cracks.The smaller tube should be warm along its entire length.

Use a carpenters level to check whether the condensing unit is level.

Cut back plants near the unit to improve airflow.

Do not place the outdoor air conditioner unit where walls, decks, fences and other structures restrict airflow.

Either move the unit or the feature restricting the airflow.
.Place the unit at least 6 feet from things that discharge heat, such as vents from water heaters and dryers.

Dryer vents also discharge lint, which plugs air conditioner coils.

Shut off your air conditioner when mowing the lawn to prevent clippings from getting sucked into the condenser.

And point the lawnmower discharge away from the condenser so it doesn't throw stones or other objects into the condenser's delicate aluminum fins.

it has a nasty smell like diesel fuel in the freezer but it works fine.

Your cooling unit may have a leak, and you are smelling the coolant, though normally this would be ammonia.

You may have food that is spoiling as well. Check the condensate / drip tray at the back of the fridge (inside). Look for water building up (likely green as well). If water is not draining, clean the hose that leads from the drip tray to the exterior back of the fridge. There will be a small evaporator cup / tray that the hose empties into. Check the end of the hose for insect activity. Note that it is normal for the end to be crimped, or it may have a plastic plug (perforated) inserted as well.

hot refrigerator

There are 2 or 3 things that would cause this. first make sure the condenser coils are not plugged with dust (vacumn or blow them out) next check to make sure the fan that cools these coils is running, (this is the most likely problem). if both of these check out ok then you would need to check to make sure your interior lights ar going off when the doors are closed as these will add extra heat and cause the center rails to run hot. last and most uncommon would be a freon system problem.  

fyi there is a hot gas freon line that runs in between the doors to prevent exterior sweating. when poor or no air flow problems for the condenser coil exist it causes this area to become hotter. 
One more thing. if you do determine that the condenser fan motor is bad you can put a normal house fan blowing on to the coil to help cool this area down until you can get the unit repaired. 
If you need any further assistance leave me a comment here and I'll gladly get back to you. Thanks Peyton

remove two small commercial refrigerators

The refrigerant must be recoverd or drawn into the condensing unit and the service valves closed.
If you do not have service valves that will close, you must recover the refrigerant.
