Vehicle A/C Repair and Maintenance

Why should I have a Professional ASE Certified Technician maintain and repair my vehicle’s HVAC system?
















The A/C system in your vehicle is a crucial component in making life in Tucson bearable with the onset of our 100+ degree temperatures.  It creates a comfortable environment for drivers and their families while out and about. Proper maintenance and repair techniques are vital to ensuring this system stays functioning properly and doesn’t leave you on the side of the road in the middle of summer. 


Over time you may experience problems with the A/C system in your vehicle.  It may start blowing warm air with the A/C on. Or the volume of air coming out of the vents may reduced.


A leak in the refrigerant system can cause the A/C compressor to not engage.  This leak will need to be repaired and the proper A/C refrigerant installed per the vehicle manufacturer’s specifications.  Install the wrong refrigerant. Not enough refrigerant. Or too little refrigerant. Can all lead to other issues or damage to the system in some cases. Having a trained and certified technician repair your system is key to avoiding these issues.


Reductions in air volume are most likely caused by a dirty or restricted cabin air filter.  This filter is usually located behind the glove box in the HVAC case.  It should be inspected at regular intervals to ensure it is clean and free of any debris or contaminants. Issues with the actual door mechanisms inside the HVAC could also be the cause of a lack of air flow. 


 We have all seen the commercials for “A/C Pro” or any other similar products out there, that claim you can do it yourself. Please keep in mind that most of these products contain some type of ‘stop leak’ or sealant in them that can cause serious damage in today’s modern refrigerant systems. It may seem like an inexpensive way to get some cold air back flowing, but in reality it can lead to costly repairs in the long run.
