When a car AC blows hot air during summertime, most drivers think it needs a refrigerant recharge from an auto repair shop in Chamblee, GA. While that may be a solution, many other things could be causing the AC not to work properly. Leaking refrigerant, broken compressors, malfunctioning condensers, obstructed expansion valves, or faulty electrical parts can keep the AC from working effectively.
At Wrights Car Care, we take an extensive approach to diagnose the whole system. Our experts help to identify the exact problem. Then we’d go ahead to suggest practical but affordable solution.
In this article, we will discuss what makes your AC blow warm air and how to fix it. Relax, read to learn more.
A good AC system should have refrigerant and the right amount of oil, but there should be no unwanted air or moisture. If a system is open, repaired, or has lost refrigerant, then air may infiltrate the system. Also, moisture may become lodged inside and lead to corrosion and operational issues.
A recovery machine is used to evacuate the existing refrigerant during an evacuation. Then, a vacuum pump removes air and moisture from the lines. This is a critical step for Wrights Car Care because merely filling the system with refrigerant won't eliminate the contaminants already present.
Following evacuation, the system is maintained at vacuum to observe whether it will remain that way. If the vacuum increases suddenly, it could be a leak that needs attention. Recharging after locating the problem will prevent loss of newly added refrigerant.
That's where the expertise of an auto repair professional comes in. They are careful about the detail and check the vacuum results properly and not just a glance at the gage.
Once the system has passed the vacuum test, the old refrigerant is replaced with the correct type and amount. This amount is important since too little can result in less cooling, and too much can also have an effect on performance.
For that, a knowledgeable technician does not make assumptions about how cold the air feels, but rather follows the specifications of the car manufacturer. This is the standard practice at a good auto repair shop.
The accurate diagnosis of AC problems requires more than a checklist. It needs hands on experience which includes the ability to read pressure gauges, understanding how components work together and what a normal cycle looks like.
This is a core part of auto repair since two cars may have the exact sign but completely different problems.
A full evacuation and recharge is done to restore the AC system to proper operating conditions. Removing the old refrigerant, air and moisture, checking for leaks and installing the correct charge provide a more reliable basis for efficient cooling performance.
When you hire a certified team from an auto repair shop, you can be certain that it will be done properly, instead of being skipped to save time.
A complete AC evac and recharge is a thorough task that is not just about a refrigerant refill. Each step goes towards ensuring the system is clean, properly charged, and functioning as it should.
When the work is handled well, Wrights Car Care helps customers get more consistent cooling from the car's air conditioning system.
