If it flat out does not function at all, it is possible an electrical connector was not re-attached. But there are actually quite a few possibilities, such as the condenser fan not being re-attached, not working, or damaged; the condenser blocked by dislodged debris; a coincidental leak (which can only be determined by state of charge, pressures, and infrared leak detector). I would take it back to the mechanic to have them check the work. If the problem still persists, or you would like to have this checked elsewhere, a certified technician from YourMechanic can come to your home or office to inspect the AC.

In general, this problem is caused either by a dirty condenser and fan or a clogged condenser. The condenser unit won`t turn on: If your condenser unit won`t turn on at all, you may have a faulty motor or the unit may not be receiving power. Examine all wiring and ensure that the unit is plugged in.
If the engine is running hot or overheating, it can have a noticeable negative affect on the air conditioning system. Some cars have two electric cooling fans, one for the air conditioning condenser and the other for the radiator. Make sure they are both working properly.
The air-conditioning condenser is a radiator positioned between the car`s grille and the engine-cooling radiator in which the gaseous refrigerant sheds heat and returns to a liquid state. The liquid refrigerant flows to the evaporator inside the dashboard, where it cools the cabin.
Automotive ac compressor lubrication is negatively impacted due to the high oil temperature that results from a lack of radiator fan assembly operation. Too high oil temperature will change the oil properties and will affect the hvac compressor internal lubrication and the a/c compressor pumping capacity.
Look for it first around on the exterior of your machine, especially along the bottom edge near the ground. An AC`s reset button is typically red and visible, so it should be easy to spot. If you don`t see a reset button on the outside, it could be located inside the unit behind the service panel.
When the engine reaches ideal operating temperature, the thermostat opens and allows the cooling system to flow freely. When the radiator stops working correctly, too much pressure is put on the thermostat, often causing it to stop working.
Yes indeed. Air conditioning is all about transfer of heat. Radiators exchange heat. AC systems actually have two radiators.
Your vehicle`s A/C condenser is usually located in the front of the radiator, giving it the nickname of the mini-radiator. When the compressor is pressurizing the refrigerant, the condenser works to reduce the temperature and pressure of hot gasses coming from the refrigerant.
The refrigerant of an air conditioner is flowing inside. The car condenser and radiator are actually the same things, that is, the outdoor unit of the air conditioner at home. The condenser is called in written form, while the radiator is commonly called, which is used to dissipate heat during refrigeration.
A clogged or damaged condenser can also cause compressor failure, as a poorly functioning condenser won`t remove enough heat from the refrigerant. This can sometimes mean the refrigerant remains in a liquid state when it`s pumped to the compressor, and that`s bad.
If your air conditioner is running, but not lowering temperatures inside, one issue could be a blocked or clogged condenser coil. When operating correctly, the condenser fan draws air into the outdoor unit through the condenser coil to pull heat energy out of your home.
If your air conditioner will turn on, and your thermostat is set properly, but your system is not cooling you may have a dirty or blocked air condenser. Your first step is to check the outside unit and clean around and remove any debris or weeds that are blocking air circulation.
Some air conditioning systems have a reset switch, which is a small, red button. Typically, the button will be on the outdoor unit. If you have a problem locating it on the outdoor unit, you may find relevant details on the equipment`s manufacturer`s manual. Press the red button for three seconds and release.
Air conditioning sensors are components of the system that measure the temperature in the room. These sensors help your air conditioner to regulate the temperature of the air according to the setting on the control panel. A sensor that isn`t working properly can`t accurately measure the temperature in the room.
Check oil and transmission fluid levels in case any was lost during the installation. This is an excellent time to flush your coolant system and replace the old coolant with new coolant. Unless the coolant was recently replaced, we highly recommend performing a flush and fill.
Clogged air filters are one of the most common reasons a thermostat clicks but AC does not turn on. A filter cleans the air before it circulates throughout your home, trapping dirt particles, dust, and pollen. Over time, these contaminants will clog the filter, limiting airflow to the HVAC system or furnace.
AC Problems a Thermostat Might Cause
Short-cycling places immense strain on the compressor, raising electrical bills and shortening the systemsb lifespan.
Start your car`s engine and allow it to idle. Look through the radiator filler neck to see if the coolant flows. At this time, it should not be flowing as your car has not reached the operating temperature to cause the thermostat to open. If you find the coolant is flowing, it means the thermostat valve is open.
The job of the compressor is to pressurize the refrigerant, turning it from a gas into a liquid. The condenser`s role is to further cool down the refrigerant and exchange heat with the surroundings.
The good news is that even though your AC condenser is somewhat vulnerable to damage and wear, most of the time you can expect it to last the life of your car. Signs that your AC condenser needs to be replaced include: Leaking. Air not as cool as it should be.
The flow rate of cooling air passing through the radiator of the cooling system decreases when a condenser is installed in front of it, due to an increase in the total resistance. 2. When the air conditioner is operating, the temperature of the air entering the radiator is higher than the ambient temperature.
The evaporator coil is the part of an air-conditioning system that removes heat and moisture from indoor air to cool it. The condenser coil takes that heat and releases it outside.
In the Automotive industry, there are mainly three types of AC condensers in vehicles` ventilation systems- serpentine, tube, and fin, and the most popular parallel flow condenser.
You will want to have the unit examined to look for signs of a blown fuse, a tripped circuit breaker, a broken thermostat, or dirty air filters. Dirty or clogged filters commonly make AC compressors stop working.
