Age and moisture are the culprits behind an A/C system leak. Rubber seals and hoses experience deterioration over time and breakdown allowing the loss of refrigerant, and the entry of moisture into the vehicle’s A/C system. Once moisture enters the A/C system, it mixes with refrigerant and creates a corrosive acid that is destructive to the system. Furthermore, moisture can damage the system’s accumulator, receiver or drier. These components are responsible for removing moisture from the A/C system and will eventually stop functioning once moisture enters the system through a leak or crack. If you suspect a problem with your vehicle’s AC system, bring it in to Fifth Gear Automotive for auto AC repair in Lewisville, TX.


Odor in AC

If the smell emanating from your AC vents has you wondering what’s going on, there are two typical causes including a dirty air cabin filter, and a moldy evaporator case. This is typically due to a stopped up AC drain, which has allowed moisture to remain in the case. There are a few issues that may be causing this smell. Our certified mechanics’ can provide the auto AC repair in Lewisville, TX that you need.

Fluctuating between Cold and Warm Air

As with most AC problems, there are several potential causes for an AC fluctuating between cold and warm air.

  • The expansion valve distributes the proper amount of refrigerant to the evaporator. When the valve is blocked, the refrigerant can’t flow into the evaporator, and the valve will freeze if moisture is present.
  • When a faulty compressor clutch fails to engage with the compressor, the compressor can’t maintain the correct pressure, resulting in warm air.
  • Fuses will sometimes blow and the power to specific components will stop, resulting in a malfunction.
  • As previously noted, AC leaks are the result of age, moisture and occasionally damage. When moisture and refrigerant mix, the corrosive acids that result break down seals and other components, resulting in a leak.

When Cold Air is as Cold as it Was

Once again, there are a number of problems that are the potential cause, including:

  • A refrigerant leak caused by a failed component
  • A clogged expansion tube
  • A failed compressor or compressor clutch
  • A failed blower motor
  • A damaged or failed condenser or evaporator
  • A vacuum leak due to a loose, cracked or damaged vacuum hose
  • A failed switch, fuse, relay, control module, solenoid or other components

Don’t discount the potential damage from a refrigerant leak. When the A/C system has a leak, get it repaired early, and the cost of auto AC repair in Lewisville, TX will be less expensive. Unfortunately, waiting for repair can result in if moisture entering the A/C system and may cause costly damage to other components.
