Guide to Fixing Your Car’s Air Conditioner

Your car’s air conditioning system will become less and less effective over time. This can be fixed but it is costly. Many have tried figuring out shortcuts to save money during fixing their cars’ AC. Below we tackle some of the popular questions and myths.

  • Many ask how much refrigerant leakage is normal. The answer is, it can be nearly airtight but refrigerant will always try to push its way out. It’s a liquid while in the A/C system but leaks out as gas so chances are, you won’t see it.
  • Running an A/C that blows warm air will hurt it. Blowing warm means it has already lost a lot of the refrigerant. To avoid running the system to dry, make sure there is a constant supply of lubrication oil. This oil is mixed with the refrigerant needed to keep your A/C running smoothly.
  • You could get used refrigerant when you get your A/C system recharged. However, nothing is wrong with that. Used refrigerant doesn’t lose its effectiveness with age. But you can always use the extra money you won at real money online pokies if don’t have enough savings.
  • If you do not drain out the entire old refrigerant first before refilling, you’re A/C might go kaput. When replacing R12 with R13a, mixing too much of them creates a weird pressure. R12’s mixed-in lubricant is mineral oil. R13a’s is synthetic PolyAlkylene Glycol (PAG) oil. These two don’t mix well together. Make sure you drain out all of the R12 before filling it with R13a.
  • Sometimes, you might need to replace the condenser and compressor when converting an older car to R134a. Some cars’ condensers made for R12 may not have the capacity that is needed to reduce the high-side pressure when R134a is installed. However, you must replace all the seals in the compressor. High labour costs come when PAG oil fails the system seals and hoses that are designed for R12’s mineral oil. So unless you have won a real money online casino jackpot you want to avoid this.
  • Lastly, never use computer keyboard duster (R152a) to run your A/C. Your A/C system will blow off. R152a is an extremely flammable hydrocarbon gas. The blower pushes air out of the dashboard vents, thereby blowing flames back at the passengers.
