The AC compressor should last for the entire life of the car,usually 8-10 years.
System maintenance and compressor efficiency
The compressor’s efficiency can be improved by maintaining the correct working conditions. This involves keeping the suction pressure as high as practical and the head pressure as low as practical within the design parameters.
A dirty evaporator will cause the suction pressure to drop. When the suction pressure goes below normal, the vapor that compressor is pumping become less dense and gets thin (sometimes called rarified vapor).The compressor performance declines. Low suction pressures also cause the high-pressure gases caught in the clearance volume of the compressor to expand more during the piston’s downstroke.This gives the compressor a lower volumetric efficiency. These gases have to expand to a pressure just below the suction pressure before the suction valve will open. Because more of the downward stroke is used for reexpansion, less of the stroke can be used for suction. Suction ends when the piston reaches bottom dead center. Low evaporator pressures cause high compression ratios.
Dirty condensers also cause compression ratios to rise, but they do not rise as fast as with dirty evaporator.A dirty condenser makes the head pressure to rise. This causes the amount of refrigerant in the clearance volume (at the top of the compressor cylinder) to be greater than the design conditions allow and the compressor efficiency to drop.
If there is a dirty condenser (high head pressure) and a dirty evaporator (low suction pressure), the compressor will run longer to keep the refrigerated space at the design temperature. The overall efficiency drops.
Evaporator core and condenser core maintenance will increase the life of the air conditioning compressor,improve the A/C efficiency and cooling capacity.With regular A/C maintenance we are saving money in the long run and getting the most out of the air conditioning system.
Auto AC Compressor service
Analysis of Denso A/C Compressor warranty claims show that in a quarter of all cases
the use of incorrect oils, such as universal oils or oil mixtures, inevitably leads to seizure and damage. This is because universal oils, are PAO-oils or mineral oils with a different viscosity to that of synthetic PAG-oils. PAO-oils do not mix well with PAG-oils and with refrigerant R134a or R1234yf, leading to poor lubrication and increased wear.
Air conditioning oil properly recharged and balanced.
Installing the Compressor without balancing the oil in the system , gives a high risk of liquid lock, due to too much oil in the A/C system!

Defrost Mode.Damage to compressor due to low refrigerant charge.
On many vehicles, by selecting the defrost position on the controls, it will also activate the A/C compressor. Cooling the air with A/C first will remove more moisture from the air so it can do a better job clearing the windows.If the A/C system is not functioning correctly this ability will be lost. If your A/C system is not working 100%,with low refrigerant charge over the winter months, you’re not getting the refrigerant oil back to the compressor which is damaging it all winter season that will lead to costly repairs in the spring time. If you run into any issues regarding this system have a professional mechanic from Auto A/C Repair. help you diagnose and fix it.

The hvac compressor is designed to last for the entire life of your vehicle and sometimes leaking compressors shafts seals could be fixed by only replacing the seals.
Avoiding inactivity of the A/C system for long periods of time is the best way for keeping the main seals lubricated and to prevent the compressor shaft seals to dry up again.Save money and time,give us a call at: 786-483-9406. Auto A/C Repair LLC. for a free check up and estimate.
In-cabin air filters.
The primary purpose of cabin air filters, located on most vehicles since 2000,is keeping the air inside your vehicle’s cabin clean.
It’s typically located behind the glove compartment or under the hood or dashboard on most modern vehicles. Its job is to filter all of the air that comes through the car’s hvac system to prevent pollutants, such as dust, pollen, smog and mold spores from entering. The filters can also catch rodent droppings, leaves and other unwanted debris.
If you don’t change it, the filter could get clogged with dirt, dust, smelly mold and allergens, and can even impact the performance of your defroster and your heating and air conditioning blower motor.
Most manufacturers recommend removal and replacement of your cabin air filter once a year or after 12,000 to 15,000 miles of driving. However, this is just a rough guideline. If you routinely drive in places with poor air quality, like the desert where it’s dusty or urban areas with smog, then you may need to replace your cabin air filter more frequently.
If you’re having trouble finding a new filter or locating your old one inside your car, give us a call at (786) 483-9406 Auto A/C Repair LLC we’ll be glad to help you.
