Restoring Comfort with Reliable Automotive in St. Louis

If your car's air conditioning system isn't keeping you cool in the scorching weather, there's no need to endure discomfort.

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 Reliable Automotive 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.


Ensuring Optimal Performance for Your Vehicle's Cooling System

Most car and truck air conditioning systems eventually require attention due to wear and tear. Hoses supplying the AC unit can crack, clog, or develop leaks if neglected. Let us service your car or truck to keep your cooling system operating at its best. Dial 314-733-5455 to learn more about how we can restore your air conditioning.


Common Automotive AC Repair Services


1234YF Vehicle AC Refrigerant
Our shop is prepared to recharge your car, truck, or jeep's 1234YF freon. All vehicle AC systems manufactured after 2021 rely on 1234YF freon as the eco-friendly solution for keeping your car's cabin cool.

Recharging Your Car's AC
When your car'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 Car's AC Compressor
The cool air in your car 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 car's AC condenser.

Repair Your Car'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 Car's AC Evaporator
The evaporator, a crucial component tucked just behind the dashboard, plays a vital role in your car'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 Car'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 car or truck's AC system.


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 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 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 28-32 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 car running when adding Freon?
It is advised to have your engine running while recharging your car'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 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.

what our customers say

My 2000 BMW 323i broke down and would not start near St. Louis, MO during my drive from Cincinnati, OH to Los Angeles, CA. They towed my car to the auto shop and replaced the alternator. Although the shop closes at 5:30 pm and my car arrived after closing hours, they stayed until 8:00 pm to complete the job. I found the shop to be honest trustworthy and they changed a reasonable price for the work. I was able to continue my trip with only a two-hour delay. I consider myself lucky to have my car breakdown near this shop. I highly recommend this shop. They did an outstanding job.

Honest and professional repair shop! I can't say enough positive things about the crew and owner of this shop. If I could add an extra star I would.... This is the type of shop you look for to regularly service your vehicle. On a recent road trip from PA to Colorado we had a mechanical issue that required immediate assistance. We were able to limp the vehicle into the shops parking lot on a Friday night at closing time. The owner and his son didn't shoo us away but instead put the vehicle on a lift to determine if they could get us back on the road. After about an hour, they made the necessary repair and we were on our way. The price was fair... actually better than fair considering our circumstance. Great guys with integrity and an exceptional sense of humor. Make this your "go to" shop.... I would if I weren't 600 mile away. Thanks again guys!
