Most auto air conditioners have five major components: the refrigerant carries the heat; the compressor draws in refrigerant, compresses it and moves it along; the condenser expels heat (like a car radiator); the expansion valve is a nozzle that regulates refrigerant flow; and the drier/evaporator cools the car by blowing hot interior air across the refrigerant. HowStuffWorks.com provides an automotive air conditioning overview[1] .
Typical costs:
Expect to pay $100-$300 to have a technician inspect and evaluate the air conditioner, including checking all hoses, belts and connections and then topping it off with fresh refrigerant, possibly with dye included to check for leaks, or (if the refrigerant is down significantly) recharging it by draining the old refrigerant and refilling it. There is no way for a technician to determine exactly how much refrigerant[2] is added to or drained from the system, so most shops charge the same flat fee for topping off or recharging; others have a fee for the labor and a separate fee for a set amount of refrigerant (typically two pounds) regardless of the actual amount used. CostHelper readers report paying $115-$260 to have their air conditioning checked and either topped off or recharged, at an average cost of $162.
If leaks are detected, it typically costs $150-$800 for minor repairs to a vehicle's air conditioning system and then recharging it. This generally includes replacing a few parts like hoses, sensors, or either the compressor or condenser. CostHelper readers report paying $171-$727 for minor air conditioning repairs, at an average cost of $488.
Extensive auto air conditioning repairs can cost $1,000-$4,000 or more, depending on make and model. This can include replacing many or all of the air conditioning system's parts -- compressor, condenser, hoses, sensors, belts, pressure switch and valves -- and then recharging the refrigerant. For cars built before 1995, the refrigerant will need to be converted to a type that meets current environmental requirements. CostHelper readers report costs of $1,000-$3,700 for major air conditioning repairs, with an average of $1,829.
Installing air conditioning in a vehicle that doesn't have any can cost $1,500-$4,000 or more, depending on location and the vehicle's year, make and model; luxury vehicles can cost even more. For example, Summit Racing Equipment sells complete air conditioning kits[3] for classic cars and trucks for $1,150-$1,395 for just the parts; installation by an experienced technician can take 12-22 hours at about $50-$100 an hour, bringing total costs to install those kits to $1,750-$3,595.
Motor vehicle air conditioning repairs are governed by federal and state environmental regulations, and must be done by a certified technician using specialized equipment. The Environmental Protection Agency explains how automotive air conditioning affects climate change[4] .
Repairs typically involve locating and stopping leaks; it can be tricky to find a small, slow leak in a hard-to-reach area, so it sometimes requires several attempts to fix the system. The EPA discusses the difference between topping off and recharging[5] and DriverSide.com explains the typical steps for servicing auto air conditioning[6] .
To add an air conditioning system to a vehicle that doesn't have one, installation typically includes cutting through the firewall, replacing the heater core, installing new under-hood components, modifying the dashboard and adapting the existing ventilation controls.
Additional costs:
For vehicles built before 1995, the Environmental Protection Agency estimates it can cost $100-$800 to convert from using CFC-12 refrigerant (brand name Freon)[7] to an approved substitute, depending on the make, model and age of the vehicle. However, if the conversion is done with other repair work, the EPA estimates it will add less than $200 to the total cost. The use of CFC-12 is not banned, but it is no longer manufactured in the US because it depletes the ozone layer and there are dwindling supplies of CFC-12 available.
Discounts:
Do-it-yourselfers can refresh an aging auto air conditioning system by topping if off with a recharge kit that typically costs about $40-$60. CNET[8] reviews the A/C Pro system, calling it a good DIY first step before consulting a mechanic.
Shopping for car air conditioning:
Montgomery County, MD explains what to expect[9] from auto air conditioning servicing and repairs.
Air conditioning repairs are available from car dealerships; automotive care chains like Firestone[10] , Midas[11] , Meinecke[12] or Sears[13] ; or at independent repair shops. Search the National Institute for Automotive Service Excellence[14] or the International Automotive Technicians Network[15] for local repair shops.

replaced ac compressor. I supplied new one. he complained about how the manifold didnt hook up good and it mite leak down he called the next morning to CK on it. it was good next morning. leaked down in one week. he says it's the compressor leaking oil. I'm thinking it's how the manifold he hooked up to compressor.
Decided to to replace the 35 year old aging AC system. New compressor, accumulator, orifice tube, refrigerant hoses, condenser. Flushed the evaporator. Charged with ozone friendly 12a refrigerant. Total parts/solvents/oil/vacuum pump, including tax/delivery $670 US ($897 CDN). Cool for the summer!
Was hearing a terrible rattle coming from the condensor which was shot. I purchased a used one on ebay that ended up not working (money was refunded) after the 300 or so in labour costs were incurred to install it. The other parts were purchased online for a good deal. After the send install which I was lucky that the second used one was not defective, I was in for $1500. I likely would buy a new compressor if I had to do it again. In the end I wasted 300 installing a defective compressor which apparently can't be tested until they are installed. good news the ac works and I can work all winter to pay off the credit card bill haha.
This is a 2005 PT Cruiser with 66,000 miles on it: lucky me!(I inherited the car from a retired magazine editor.) I was alerted by a sputtering sound, coming from under the engine; very loud. Plus, a/c not cold at all. Evidently, the issue was my fan,(car only has one fan), was operating at the low speed, and the refrigerant was escaping from under the engine, due to the heat build up, due to the fan not operating on the high speed. Luckily, my car never over heated. In result, my mechanic diagnosed the problem, recognizing that the fan was not working properly, he had to take apart many parts of the front on the engine to get to the fan; including the grill and the radiator, refilled the system with refrigerant and dye, replaced the fan with a new one, and put it back together. Plus labor and tax, in total $500.
AC was blowing only cool air not cold. Took driving 15 miles before cabin of truck cooled down. Mechanic thought it just needed freon but that was not the case. It needed the whole new system. My price paid is not nearly as expensive as others listed here. Work was done by a certified mechanic that is very good and backs up his work.
I went to an official Ford service location to fix the AC in my car. The staff there fixed it but I regret now that I paid 1500 just to fix a leaking issue. The parts they installed are new condenser, condenser to fender line and low side charge port valve. 675$ parts + 824$ labor. I wish that I had taken to another auto service before paying 1500$ "just" to fix the AC in my car.
Where I live, a person can't exist without a working A-C unit in the car. I tried, but finally decided I needed to do something. Someone recommended Pueblo Tires, and I'm glad they did. They're replacing the whole thing for $1900 parts and labor, and I'm also replacing my tires since they're almost six years old. I feel like I am dealing with some honest mechanics for a change. That's a good feeling.
It's a weekend during a heat wave so of course my car AC stops working. The AC light went green when I turn the air dial, but no air came out, so I figured it was the fan. After poking around the Internet, I figured I should just take it to a dealer. Anyway, it turned out a cable had come loose so just tightening it fixed the problem, although they claimed it took them 2 hour of diagnostics to figure that out. They charged me $160 with 10% off for a "mature car" discount (cars over 90k miles have a coupon on their website). Seemed pretty steep to me, but at least the prices for the other work was good, and the 2 hours did also include fixing some other small items (like replacing a knob that had broken).
AC is not fixed still blowing hot air. $450.00 totally ripped off by Firestone, they added the coolant and said they tightened the hose and did a test total rip off the car is not fixed. Please please please do not use Firestone.
no a/c good car has 105,000 miles just need last kid to use for senior year college. just did brake job tires.... blowing hot air tried charging did not work do not want to spend a fortune have appointment with a/c car shop this week How much??? looking for best advice.
2009 Honda Civic: They tested with dye and no leak noted, recharged and told to run a/c on high to force to see if there is a change in temperature and if so there may be a leak. Bring back if needed and they'll run extensive leak tests.
Air conditioner speed working. Compressor would not even kick on. Freon got to low. They did Lube and dye to check for leaks. Remove and replacedo what freon was in the system.
Replaced all O rings,flushed system, brought vacuum and manifold gauges $99 dollars, accumulator $28.00, O rings $10.00 Amazon. Compressor $130.00 had Pep Boys coupon, eBay liquid line $28.00, Advance Auto 134a oil and refrigerant $ 50.00, flush kit $19.00 and dye $10.00. Misc $20.00 gloves etc. Advance and Pep Boys takes 20-40% off if ordered online. If you borrow the vacuum and gauges subtract $99.00.
