Common Automotive AC Repair Services


1234YF Vehicle AC Refrigerant
Our facility is equipped to handle a variety of auto AC repair services, including the latest 1234YF freon recharge for your car, truck, or jeep. This refrigerant, mandatory in all vehicle AC systems manufactured after 2021, offers an environmentally friendly way to keep your vehicle's cabin cool.

Recharging Your Car's AC
If your vehicle's AC begins to lose its cooling efficiency, consider a freon recharge. This quick and cost-effective solution restores cool air, providing relief from the heat. Be aware that if there's a freon leak, it could be due to a damaged hose or seal, which might require more extensive auto AC repairs.

Repair Your Car's AC Compressor
The AC compressor is central to cooling your vehicle, performing several critical functions: it pressurizes the refrigerant to cool the air, regulates the temperature output, detects temperature changes, and channels air to the AC condenser.

Repair Your Car's AC Condenser
Located near the radiator, the AC condenser is crucial for cooling the refrigerant after compression. This component helps maintain a comfortable cabin temperature by converting the refrigerant into a cooled liquid.

Repair Your Car's AC Evaporator
The evaporator is key to your car's air conditioning system. It cools and dehumidifies the air before it flows through the cabin, ensuring a comfortable environment inside your vehicle during the warmer months.

Thermal Expansion Valve Replacement
The Thermal Expansion Valve or Orifice Tube is essential for regulating your AC system's pressure and temperature, controlling the flow of refrigerant into the evaporator. Proper balance prevents moisture build-up, crucial for maintaining your vehicle's AC efficiency.


Freon Recharging FAQs


How often should Freon be changed?

Never, at least not in the way you think of your oil being changed. Your car's AC system is a sealed unit. No new Freon needs to be added unless there's a refrigerant leak. Over time as your vehicle ages, small cracks may form in AC system components such as the compressor, condenser, evaporator, receiver-dryer, expansion tube, and connecting hoses, allowing Freon to escape. If this occurs, you need to replace the failing part and have your Freon recharged.

How long should a Freon recharge last?

If your car's AC system was recently repaired and required a Freon recharge, it should not need to be replaced again. Your AC system is a closed or sealed system that does not allow Freon to escape. Freon is not like gasoline; it does not get depleted. If Freon is escaping after your car's AC system has been repaired, then additional work may need to be done to find the leak.

How many cans of Freon does a car take?

Don't guesstimate your car's refrigerant needs! Most use 28 to 32 ounces (2 to 3 12-ounce cans), but larger vehicles and rear A/C systems can require different amounts. Check your owner's manual for the exact amount to avoid overfilling the system.

Can I leave my car running when adding Freon?

It is advised to have your engine running while recharging your car's A/C system. This is essential because the A/C compressor, powered by the engine, must be active to facilitate proper refrigerant circulation and ensure an effective recharge.

Why is my car blowing hot air after adding Freon?

A refrigerant leak can lead to a loss of pressure in the AC system, resulting in a failure to produce cold air. This is frequently the primary reason a recharge may prove ineffective. It is crucial to inspect the system for leaks and address any issues before proceeding with a recharge.

If your car is still blowing hot air after adding Freon, it likely indicates a leak which causes a drop in system pressure and cooling performance. Before adding more Freon, it's advisable to thoroughly inspect the system for leaks and repair any issues found to ensure the AC system can maintain proper pressure and function effectively.

We are extremely satisfied with Tucson Auto and Diesel! My husbands truck was pretty much dead and Josh the owner contacted us through Facebook and got us in the very next day! We had some trouble getting our truck there, but nonetheless we got it there. We expected our truck to be out for a couple days considering we had just dropped it off, and they got it back to us the same exact day! If I could recommend anyone to go anywhere for their trucks it’s this place! 10/10 experience!

Holy Cow! This place knocks it out of the park. Super friendly staff especially the greeters at the front desk. The cost for my KIA Transfer Case replacement was very reasonable compared to the "crooks" at Royal KIA service department. I will be going back here for sure, highly recommended.
