Will it hurt to keep running an A/C system that blows warm air?

Yes. By the time you notice the system is blowing warm, it’s already lost a lot of refrigerant. More importantly, refrigerant is mixed with a lubricating oil, needed to keep the A/C compressor operating smoothly, you’re likely running the system too dry, which can eventually burn out the compressor by starving it of lubrication. Most refrigerants mix in an ultraviolet-sensitive dye, so while the refrigerant evaporates away, the oil/dye mixture leaks into the engine bay and leaves a traceable stain. Waving an ultraviolet light near the A/C lines will show where the leak is.

Why is my Car is Blowing Warm Air?

1. Refrigerant Leak

A car A/C blowing hot air is often the result of a refrigerant leak. Refrigerant is a liquid that circulates through your car?s A/C system, expanding and contracting as it removes heat and humidity from the cabin. None of the other A/C components will function correctly without proper refrigerant levels.

A leak can happen because of an old hose as well as a rusted or punctured evaporator. But don?t expect to easily spot a refrigerant leak. You probably won?t notice a puddle of liquid in or under your car. That?s because unlike motor oil and other vital car fluids, antifreeze evaporates when exposed to the atmosphere. Sometimes, you?ll get lucky and notice an oily residue at the exact location of the leak.

To definitively identify a refrigerant leak, one of our expert technicians needs to inject dye into the system to trace it. Once they identify the source of the leak, they will fix the leak and refill it so it can blow fresh, cold air once again.

2. Faulty Condenser

When your A/C system pulls the heat and humidity out of your cabin, the refrigerant absorbs them. In turn, the condenser?s function is to keep the refrigerant cool so the cycle can continue. If the condenser isn?t doing its job, the process breaks down. That?s when you get slapped in the face by a blast of hot air.

The condenser is at the front of the car, between the grate and the radiator. It utilizes air flowing through the grate to assist in cooling. If the condenser is blocked or clogged by road debris, air won?t reach it, preventing the refrigerant from cooling correctly.

If you have a faulty condenser, you may be able to see the problem by looking through the grate. Also, consider whether your car A/C problems started after a fender bender or bumper bump, in which case your condenser might have broken on impact.

3. Broken Compressor

The compressor is the heart of your car?s A/C. It?s responsible for circulating the refrigerant through the system. If this part isn?t working correctly, the antifreeze won?t be able to reach the condenser for cooling.

Compressor issues tend to pop up after long periods of inactivity, such as long winters when A/C isn?t necessary. However, to prevent this from happening, many newer vehicles keep the condenser active year-round by activating it under the defrost setting.

4. Problems with the Electrical System

If all the A/C components are in working order, your car may be blowing hot air because of an electrical issue. A frayed wire or a blown fuse can prevent an otherwise healthy A/C from functioning. Diagnosing and correcting an electrical problem begins with performing a?visual inspection?of your car?s fuse box and wiring.

If any of these issues are causing your car to blow hot air, drive to your?AA Auto Repair and Tires.?We?ll give your A/C a thorough and accurate inspection. We?ll explain what?s needed now, and what can wait, so the decision?s yours. After all, at Tires Plus, you?re in the driver?s seat. Let?s make sure it?s a cool one.

Will refitting my R12 system to use R134a refrigerant make it less effective?

Noticeably. That’s the most accurate answer we can give you without knowing your car’s particular cooling system, because they can vary a lot. R12 systems weren’t designed for anything but R12, so if you’re converting one to R134a, then you have to put in about 25 percent less refrigerant to account for R134a’s higher operating pressure. R134a is a more efficient refrigerant pound for pound, says Griffiths, a Porsche air conditioning specialist, but you can’t put as much in your car’s A/C system as you could R12, so the end result is diminished cooling power.

Used Refrigerant still good?

Yep, but there’s nothing wrong with it. Shops will run the outgoing refrigerant through a recovery machine that scrubs it of contaminants like dirt, and it works just as well after it’s clean. It doesn’t go sour or lose effectiveness with age the way break fluid or coolant does.

Will your A/C system go BAD if you don't drain out all the old refrigerant first?

It could. R12 and R134a operate at different pressures, so mixing too much of them creates a system operating at a weird pressure. Also, R12’s mixed-in lubricant is mineral oil, and R134a’s is a synthetic polyalkylene glycol (PAG) oil, and they don’t play well together if combined. Any shop worth your money will vacuum out all the old R12 before converting the system and filling it with R134a.

Can you really use computer keyboard duster (R152a) to run your A/C system for cheap?

In theory?until it blows up and you’re penciling in eyebrows over your face. R-152a is an extremely flammable hydrocarbon gas, just as propane is a hydrocarbon. Atkinson has a collection of photographs of dashboard fires from people who’ve recharged their non-R152a systems with R-152a, and he says because the blower is pushing air out the dashboard vents when things light up, the flames tend to get blown back at the passengers. OEMs are already searching for an R-134a replacement, and R-152a is one they’re experimenting with, but it’s not a good idea for your old R-12 or R-134a system.

After all, air conditioning is pointless if it sets you on fire, because then you’re hotter than ever.

CAR A/C

Terminology

^

auto a/c compressor

A vehicle’s AC system is comprised of many components such as the evaporator, hoses, receiver dryer, condenser and compressor. While all of the components matter in your car’s AC system the AC Compressor is the heart of the system.
Powered by a drive belt that connects to the engine’s crankshaft, the AC compressor’s responsible for pumping refrigerant through the refrigeration cycle. The belt is connected to the compressor clutch pulley.

 

^

Drive gears

These gears are located on the output shaft. They determine the gear that your car is currently engaged in, like 1st gear, 2nd gear, ans so on. Each gear is enmeshed with the gear directly underneath it mounted on the countershaft.

^

Output shaft

This shaft runs parallel directly above the layshaft. The output shaft is what transmits or delivers the power of the engine to the rest of the drivetrain. The power and speed of the output shaft is dependent on the gears that are currently engaged.

 

^

Idle gear

This gear is located between the reverse gear mounted on the output shaft and its corresponding gear mounted on the layshaft. This is what allows the vehicle to go in reverse.

 

^

Synchronizer Sleeves or Collars

Modern cars have synchronized gearboxes. This means that the gears mounted on both the layshaft and the output shaft are always enmeshed and are always spinning. The question most people have is that if all of the gears are somehow connected to one another and all of them are spinning at the same time, how is it possible that only one of these gears will be transmitting the right amount of usable power or torque to the output shaft. Additionally, since the input shaft is technically spinning at a different speed from the output shaft, is it even possible to obtain a smooth transmission of power, This is the work of synchronizer collars or sleeves.
