Air Conditioning Repair For Cars and Trucks

How often should Freon be changed?

Never, at least not in the way you think of your oil being changed. Your truck'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 your AC system parts 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 truck'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 truck's AC system has been repaired, then additional work may need to be done to find the leak.

Five Indicators Your Truck's AC Needs Attention

• Your truck's AC blows air only slightly cooler than the outside temperature.
• Unpleasant mildew and mold odors emanate from your AC vents.
• The AC functions only while the vehicle is in motion.
• Even at the highest fan setting, there's weak airflow.
• Water condenses or drips onto your foot while driving.

Don't delay! If your truck's AC isn't operating at peak efficiency, a visit to Diesel 1 is a wise move. Routine maintenance now can help you avoid more costly auto AC repairs later. Sometimes, resolving a malfunctioning air conditioner is as simple and cost-effective as replenishing the coolant.

How many cans of Freon does a truck take?

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

Can I leave my truck running when adding Freon?

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

Why is my truck 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.

Common Automotive AC Repair Services

Recharging Your Truck's AC
When your truck's air conditioning (AC) loses cooling power or fails to deliver cool air, a freon recharge may be in order. Recharging your freon is often a fast and cost-effective repair that can help you beat the summer heat. However, a freon leak could be due to a cracked hose or seal, indicating a more substantial repair may be necessary.

Repair Your Truck's AC Compressor
The cool air in your truck primarily comes from the compressor. Your vehicle's compressor performs four essential functions: pressurizing the refrigerant to cool cabin air, regulating temperature output, sensing temperature changes inside and outside the vehicle, and directing air to your truck's AC condenser.

Repair Your Truck's AC Condenser
Typically located in front of the radiator, your vehicle's A/C condenser plays a crucial role. When your AC compressor pressurizes the refrigerant, it flows to the condenser, reducing temperature and pressure. The condenser is vital for maintaining a comfortable cabin temperature by transferring cooled liquid refrigerant to the receiver/dryer or accumulator.

Repair Your Truck's AC Evaporator
The evaporator, a crucial component tucked just behind the dashboard, plays a vital role in your truck's air conditioning system. By efficiently cooling and dehumidifying the air before it circulates throughout the vehicle's cabin, the evaporator ensures a comfortable and refreshing interior climate, especially during warmer seasons.

Replace Your Truck's AC Thermal Expansion Valve or Orifice Tube
The Thermal Expansion Valve or Orifice Tube monitors A/C system pressure and temperature, determining the precise refrigerant amount that can safely enter the evaporator. Imbalanced pressure can lead to unwanted moisture buildup in your truck's AC system.
