JB Weld is not strong enough for the high side without a saddle to spread the pressure out. You'll need to replace it for it to not leak. JB Weld is not strong enough for the high side without a saddle to spread the pressure out.

Similarly one may ask, will JB Weld work on a AC condenser?

Don't use JB Weld on anything that builds pressure such as a condenser or intercooler. They sell those front condensers in the OEM replacement model or those aftermarket ones. Do yourself a favor and start with a fresh one, that way it will flow better with cleaner cooling fins.

Secondly, what happens when AC condenser goes bad? Signs of a failing AC condenser AC doesn't cool properly: Because the condenser removes heat from refrigerant, a problem with the unit will keep the system from getting cold. Icy spots on the condenser: If the condenser is restricted, frost may accumulate near one end.

Also to know is, can an air conditioner condenser be repaired?

The condenser is made up of various parts. When the condenser breaks down it typically means that one or more parts in the condenser will have to be replaced. The cost of repair might vary from $150 to $1,000. In most cases though, homeowners are able to repair minor air conditioner issues.

How long do AC condensers last?

10 to 15 years

Do you have to replace condenser with compressor?

Compressors and condensers are often replaced simultaneously, mostly because compressor failures leave behind debris that the condenser collects. If this debris isn't 100% removed, it will cause the new compressor to fail as well.

How do I know if my AC condenser is bad?

How do I know if my air-conditioning condenser has gone bad? The air will be warmer than you want, or your vehicle windows will be foggy. If refrigerant leaks, the air conditioner won't spit out much cold air, if any. Leaks can be located by adding an ultraviolet dye to the refrigerant.

How much does it cost to replace a AC condenser?

Home AC Condenser Repair & Replacement Cost
Repairing an air conditioner condenser costs an average of $150 to $1,000 or more. Replacing the entire coil runs $900 to $2,800. Labor alone makes up about half the fees. HVAC technicians charge anywhere from $50 to $150 per hour.

Where is the condenser on a AC unit?

These condenser units are located on the outside of the building they are trying to cool, with tubing between the unit and building, one for vapor refrigerant entering and another for liquid refrigerant leaving the unit. Of course, an electric power supply is needed for the compressor and fan inside the unit.

When should I replace my AC condenser?


Energy Star recommends upgrading to an energy-efficient unit if your current central air conditioner is 10 or more years old. Many HVAC technicians say they typically recommend replacing units if they are 15 years or older.

What does a condenser look like on an AC unit?

The outside unit, called the a/c condenser, contains a compressor, cooling fins and tubes and a fan. The fan sucks air through the fins and cools a special coolant, which the compressor then pumps into the house to the evaporator through a copper tube. The coolant chills the fins and tubes of the evaporator.

Why is my AC condenser leaking?

A clogged condensate drain line is the most common cause of water leaking from your AC into your home. If the drain line gets clogged with dust, dirt, sludge or mold, that water backs up into your home. In that case, you'll need to unclog it.

Does coolant run through AC condenser?

The radiator releases heat from the hot engine coolant passing through it, to the atmosphere. The condenser releases heat from the hot A/C system refrigerant passing through it, to the atmosphere.

Can you repair an evaporator coil leak?

Sadly, repair isn't an option.
There's no reliable way to repair the leaks themselves. Evaporator coils are large components that reside in dark places and are characterized by tiny dips, curves, crevices, and hard-to-see, hard-to-reach areas.

How much does it cost to fix an AC condenser in a car?


To have the AC condenser replaced you will pay anywhere between $450 and $950, depending on where you go to have the work done and what kind of cars you have. The labor costs vary based on the kind of car you have, with prices starting at $130 and going up to $350. The parts will cost between $250 and $400.

How do I know if my condenser is leaking?

The second and more scientific way to check for leaks is to add UV dye to your air conditioning system, let it run for a day or so, then use a UV light to check for the dye around the condenser. If there is a leak, the dye will show up on the outside of your condenser under the UV light.

Where is the evaporator coil located?

An air conditioner's evaporator coil, also called the evaporator core, is the part of the system where the refrigerant absorbs heat. That is, it's where the cold air comes from. The evaporator coil is located inside or near the air handler where the blower fan is.

Can I replace my AC condenser myself?

Replacing the air conditioner condenser is a job for a trained and certified technician, not the average do-it-yourselfer. The condenser is not simply a bolted-in part that can easily be swapped out, but is integrated throughout the cooling system.

Can you replace just the condenser?

Your Condenser Unit Could Solely Be to Blame for a Broken AC
A common question we get is if you can replace just the condenser. The short answer is yes, you can. Some technicians often do in some cases. Your AC system can actually suffer since its components will be mismatched.

Do I need to add oil after replacing condenser?


Replacing the condenser is simply unbolting. Lubricate NEW o-rings with compressor oil and observe the tightening torques when replacing. Then take it to the shop for leak testing and refilling. Be sure to tell them the condenser was replaced so that they can add the appropriate amount of oil.

Where are AC condenser coils?

Your condenser coils sit directly behind the condenser “fins”—the thin metal wiring that covers your outdoor AC unit (see the picture above). As refrigerant travels to your outdoor unit, it fills the many condenser coils, increasing its surface area so that heat escapes faster.
