PORTLAND AIR CONDITIONING REPAIR
Nothing is more uncomfortable than being behind the wheel of a vehicle on a hot summer day with no Air Conditioning. Air Conditioning issues can be cause by many different things, our trained mechanics will take the time to diagnose your vehicles symptoms and have you back on ice in no time.
Does Your A/C Have Weak Airflow?
Main causes of weak airflow:
- Mold or mildew may have accumulated in the evaporator core from residual moisture that occurs during the cooling process. When this happens, air will have trouble reaching your air vents.
- A hose has come loose. This usually happens with the blower hose that supplies air to the blower unit.
- Ventilation fan is fried. If the fan’s not blowing, air won’t be flowing very well.
- Core case seals, blower house seals or evaporator core case seals; All can open up and diminish air flow. A/C ventilation systems are very sensitive and must remain sealed. Once they’re opened, the whole system becomes compromised.
A/C Not As Cold As It Used To Be?
There are several reasons an A/C system can lose its cool. Bring your ride to us as soon as you start noticing this symptom, it could mean the difference between needing a small repair, or worse, a large one. Here’s what can cause your cold air to lose its cool.
- A Freon leak caused by a failed o-ring, seal, hose or component
- A clogged expansion tube or refrigerant charging hose
- Failed compressor or compressor clutch
- Failed blower motor or blower motor resistor
- Damaged or failed condenser or evaporator
- Vacuum leaks
- Failed switch, fuse, relay, control module, blend door or solenoid
How Do You Test For An A/C Leak?
- Black light enabled dyes. Most refrigerants are pre-mixed with a specialV. dye that shows up under black light. We’ll run a black light over your A/C system to see if any dye shows up.
- We will use the “sniffer” tool. A sniffer is a special device that hones in on the refrigerant’s chemical components. If there’s a leak, our sniffer will sniff it out.
What Causes an A/C Leak?
Age and moisture. Overtime rubber seals and hoses lose their elasticity and breakdown allowing Freon to escape and moisture to enter your vehicle’s A/C system. Moisture kills the A/C system, mixing with refrigerant and creating a system destroying corrosive acid.
Quick fact: If moisture is present, it could damage your accumulator, receiver or drier. Remember, these devices are responsible for removing moisture from the A/C system and will eventually stop functioning once they are exposed to an open system (leak or crack).
