How much does it cost to repair a car air conditioner?Ĭar AC repair is generally more affordable than replacing components. Air is blown over these supercooled tubes and into the cabin as cool air. Evaporator: Located behind the dash, the evaporator turns the liquid back into a gas in tubes.Expansion valve or orifice: Allows the system to bleed off pressure at a carefully measured rate and quickly lower the temperature.Dryer: Contains a material (known as a desiccant) that removes water from the refrigerant.Generally mounted near the grille of your vehicle. Condenser: Uses moving air to rapidly cool the high-pressure, high-temperature gas, turning it into a low-pressure liquid.Compresses low-pressure gas into a high-pressure, high-temperature gas. Compressor: Functions as a power unit for the system and is attached to the engine via the serpentine belt.To better understand this complicated process, here’s a closer look at each major component in an AC system and how it functions. If you need an AC Unit repaired and your AC Compressor looked in the Mesa, Gilbert, Chandler, Tempe or East Valley area of Phoenix at contact Dukes of Air for an assessment.In a technical sense, air conditioning works by forcing a refrigerant to change from liquid to a gaseous state in a pressurized closed loop. An HVAC technician can usually swap out the old one with a new one to solve this issue and ensure your unit starts up correctly every time. If the capacitor in your compressor is damaged, it may be difficult for it to start up. AC Unit CapacitorsĬapacitors and Start Relays Are Other Common Issues That May Cause Your Compressor to Stop WorkingĬapacitors and start relays are two common components that could be the culprits behind why your compressor has stopped working. It is essential to remember that the compressor is one of the most costly components in an air conditioning system, and usually fails first when something goes awry. In such cases, trying to force it back into working order may prove challenging and your home’s temperature won’t be as consistent as usual. If your air conditioning unit isn’t blowing cold air, it could be a sign that its compressor is about to fail. However, if you turn off the power to the unit or have an electrician inspect its breakers, this issue often gets resolved without needing costly repairs. If the unit has a warranty, you may be eligible for coverage that will reduce costs even further.Ī blown fuse or tripped circuit breaker are common causes for an AC compressor to stop working. The cost to replace an air conditioner compressor varies by manufacturer and model, but is usually cheaper than repair. They may also cause frequent cycling and a hissing sound. When refrigerant leaks occur in an HVAC unit, they can lead to numerous issues for the unit such as lack of cool air or insufficient ventilation. Semi-sealed air conditioning compressors have their motor and engine enclosed in a hermetically sealed “can.” Open type compressors lack this protection, necessitating refrigerant to be pumped into them. It’s best to have an expert take a look at your unit and provide you with the most cost-effective solution. When considering whether or not your air conditioning unit needs repair or replacement, several factors like its age and cost must be taken into consideration. An AC Repair technician may be able to replace damaged ducts, but in some cases you’ll require a full AC unit replacement. This could be due to blocked, damaged or clogged overheating ducts as well as defective wiring.įaulty refrigerant lines can lead to refrigerant leakage, wreaking havoc on your entire system. Overheating is another common issue that can cause your compressor to malfunction. It’s essential to regularly lubricate and service your compressor, in order to avoid costly AC compressor repairs in the future. When the compressor fails, it could affect several components of your AC system including the condenser and evaporator. Prior to diagnosing and fixing any problems you might experience with your air conditioning compressor, it’s essential to understand how it operates. But there are simple steps you can take to identify and resolve the problem before it worsens. Even on the hottest summer days, an AC unit that malfunctions can make a home unbearably hot.
