The expansion valve is usually in the evaporator and simply opens or closes to allow the appropriate flow of refrigerant into the coil. The theory is that the expansion valve makes your AC run more efficiently.

you can probably get away with that just make sure you have an expansion valve on the evaporator. An expansion valve will keep liquid from getting back to the compressor.

That would depend on where in the system the valve is. In many instances you can pump down the unit so all of the refrigerant is in the condenser and change a valve that is on the low side of the system or indoors.

How do you replace the expansion valve on a 92 Honda civic?

The expansion valve is found inside the evaporator housing. To replace the AC system needs to be flushed legally. Then valve is only held down by a few mounting screws. Once the AC system is bled, loosen the screws and replace the unit.


Can air conditioner compressor on a 1999 dodge Dakota 5.2 liter be rebuilt?

No, it's best to buy a new factory unit but when your compressor goes bad you will also need to change the dryer,expansion valve and outside condenser unit as well, because of debris from the compressor. Some mechanics will try and flush the system or use air to blow out the debris but in the end the customer will be back with the same trouble again. It is possible to buy used compressor and o/s condenser but always buy new expansion valve and dryer and save a little money you just don't get a warranty.I have done this for over thirty years but I could be wrong, so do the job right and stay cool all summer.

Where is expansion valve located on 1995 Toyota 4runner?

The expansion valve, will be in the AC unit on the Passenger side of your truck, right behind the glove box. First remove the glove box, and the the screws on the perimeter of the ac box as well as in front, it should open up, and it will be at the top right front of the box.


The rear ac unit of your 2003 Tahoe does not blow cold the front works fine the line to the rear does not get cold like the line to the front?

I believe the rear Expansion Valve may need replaced. If it has failed the rear evaporator will not cool as the freon will not flow. These Tahoes have an orfice up front and an expansion valve in the rear (inside the rear HVAC unit under the passenger quarter trim). The coolant lines and the A/C lines have to be undone to remove the HVAC system from the vehicle to replace the Expansion Valve. It's about 650 at the dealer (or you can get the valve for under 100 from an auto parts store if you think you can do the job yourself).

What parts of a home air conditioner unit could leak freon?

Just about everything: The compressor, the condensor, the evaporator, the expansion valve or capillary tubes, all of the piping, the reversing valve if it is a heat pump, the valves, the service ports, the filter/drier if there is one. Refrigeration service techs have a special 'sniffer' used to find the source of a leak.
