Are there any lights to alert me to an A/C problem?

Usually not, but some vehicles have a built in diagnostic system that might alert you to a problem. Check your Owner’s Manual for more information.

What should I do if my A/C isn’t as cold as it used to be?

There are several reasons an A/C system can lose some of its ability to cool the air. The sooner you have it looked at, the better as it could help prevent more costly repair. Here are some of the reasons the air isn’t blowing cold:

• Freon leak somewhere in the system.
• A clogged expansion tube or refrigerant charging hose
• A/C compressor or compressor clutch could have gone bad.
• The blower motor or blower motor resistor could be failing
• Your condenser or evaporator could be failing.
• Vacuum leaks in the line could reduce your A/C units effectiveness.
• Failed switch, fuse, relay, control module, blend door or solenoid

A leak in the system can make your A/C system not work. If your technician discovers the leak early enough, your repairs can be much less expensive. If a leak has been affecting your system for a while, moisture may have entered your A/C system and have damaged other more expensive parts.

My A/C starts out cool then gets warm, what’s wrong?

Unfortunately, there’s never one answer. There are several reasons this could be happening, and the best thing to do is to have us inspect your A/C system. Call us at 972-552-9908, or schedule an appointment.

Here are some reasons this could be happening:

• Failed compressor clutch: If the clutch is not engaging with your compressor, than your compressor can’t maintain the correct pressure. Hot air will result.
• Clogged expansion valve: If the valve is clogged, the refrigerant can’t flow into the evaporator.
• Blown fuse.
• Leaks will certainly make your A/C system not function properly.

What is that stale smell coming from my A/C vents?

There are a few reasons you might be having that problem.

Potential causes of a stale odor:

• Dirty air cabin filter. – Simple solution is to replace it regularly.
• Mold in the evaporator case. If the case gets clogged, and liquid isn’t able to draing, mold can form.

What causes an A/C system leak?

Age and moisture are an A/C systems worst enemies. Seals and hoses can crack over time and allowing Freon to escape and moisture to get in to your vehicle’s A/C system. Moisture, mixing with a refrigerant creates a corrosive acid.
