Ac evac and recharge cost5/4/2023 ![]() ![]() When you have the shop recharge the system, make sure they do at least a 15-minute leak check (no one wants to do the same thing twice). Make sure you have turned the power off in the car and disconnected the 3 phase high voltage lines running to the compressor. A shop would probably charge you a standard evac and recharge fee of around $150. You could then swap the compressor out, take it back in and have them leak check, and recharge it. If I added my time into that, it is about a hundred bucks.Īnyone could do this procedure if you take it to a shop and have them recover the system. The used (but still good) compressor in the pick n pull was fifty dollars. I also have a great friend who owns a repair shop and lets me use his machine. I was able to get this Prius back working again for less than 100 dollars. This is one reason A/C work is so expensive, all of the labor and components involved. Typically with catastrophic compressor failure, as I mentioned above, can completely ruin the majority of the a/c system. The proper way to replace a failed compressor is to replace the compressor, condenser, receiver/dryer, and sometimes the thermal expansion valve or TXV. If not, I did have the money set aside to overhaul, but it was worth a shot. I figured that if I could get it working again by replacing the compressor and recharging the system, that would be a total win. Replacing only the compressor and having the system open for a short time was not long enough to saturate the desiccant bag and hold excess moisture inside the system. The compressor was weak but not totally failed, which told me that my system was primarily clean. So, why did I only replace the compressor and nothing else? It was a 100% roll of the dice. The internal metal particles and the tiny ports do not work well together. If a catastrophic failure occurs, plan on replacing nearly the entire system. On the low side, refrigerant pressure is building because it is not being drawn in quickly thus, the low side has higher than normal pressure. Key signs of a failed compressor are High low side pressure and Low high side pressure.Ī weak compressor cannot build pressure, which is why we see the high side with low pressure. The first thing you must know when diagnosing a failed compressor is if it has actually failed. What Can Be Done To Repair A Failed Compressor? ![]() There are other reasons for failure, but in my case, it was from lack of use. The oil in the system settles, seals, and bearings dry out, and then when turned on, the compressor cannot make the same pressure it once did. One of the reasons A/C compressors fail is due to lack of use. A failing compressor is not unheard of, though, and my "garage find" Prius just had this problem. We will analyze why it failed and how I could get it back up and going again for less than one hundred dollars.Įlectric air conditioning compressors such as the ones found on Toyota Prius do not fail often. In this article, we will look at the "garage find Prius" and its failed compressor. But what if we do not get cool air and only get heat? Sometimes our A/C systems fail and need attention. When the outside temperatures spike, we all want to turn on the cool air from our vents.
