Five Indicators Your Car's AC Needs Attention
- Your car'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 car's AC isn't operating at peak efficiency, a visit to Hill's Auto Repair is a wise move. Routine maintenance now can help you avoid higher auto AC repair costs later. Sometimes, resolving a malfunctioning air conditioner is as simple and cost-effective as replenishing the coolant.

Common Automotive AC Repair Services
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, the failing component should be replaced and the system 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 recharged again under normal circumstances. Your AC system is a sealed system that does not allow refrigerant to escape. Freon is not like gasoline and does not get used up. If Freon continues to leak after repairs have been completed, additional diagnostic work may be needed to locate and repair the leak.
How many cans of Freon does a car take?
Don't guesstimate your vehicle's refrigerant needs. Most cars use between 28 and 32 ounces of refrigerant, which is roughly equal to two or three 12-ounce cans. However, larger vehicles and those equipped with rear air conditioning systems may require different amounts. Always consult your owner's manual or manufacturer specifications to avoid overfilling the system.
Can I leave my car running when adding Freon?
Yes. It is generally recommended to have the engine running while recharging your vehicle's air conditioning system. The AC compressor is powered by the engine and must be operating to circulate refrigerant properly and ensure an effective recharge.
Why is my car blowing hot air after adding Freon?
A refrigerant leak can cause a loss of pressure within the AC system, preventing it from producing cold air. This is one of the most common reasons a recharge may not solve the problem. The system should be inspected for leaks and any damaged components should be repaired before additional refrigerant is added.
