Air Conditioning Repair For Cars and Trucks

Restoring Comfort with Highlands Auto Center in Dallas

If your car's air conditioning system isn't keeping you cool in the scorching weather, there's no need to endure discomfort. Come over to Highlands Auto Center in Dallas, where we'll swiftly restore your AC's performance. Reach out to us now at 972-233-8882 or drop by our shop at 10524 East Northwest Highway, Dallas, TX.



Five Indicators Your Car's AC Needs Attention

  1. Your car's AC blows air only slightly cooler than the outside temperature.
  2. Unpleasant mildew and mold odors emanate from your AC vents.
  3. The AC functions only while the vehicle is in motion.
  4. Even at the highest fan setting, there's weak airflow.
  5. 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 Highlands Auto Center 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 972-233-8882 to learn more about how we can restore your air conditioning.


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 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 at the front of your vehicle, 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 that moves to the receiver/dryer or accumulator.

Repair Your Car's AC Evaporator
Situated just behind the dashboard, 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.

Replace Your Car's AC Thermal Expansion Valve or Orifice Tube
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 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.

We took our 2007 Jeep Liberty in due to some engine problems. Well, they looked in over and told what I had already suspected - the engine was in bad shape and loosing oil.The owner of the garage made some phone calls and presented us with a price much lower than we expected. We had them do the job (in one and a half weeks) and one their quoted price, we've driven the Jeep for a few days now without any problems. They did a great job and I would recommend them to everyone. Thanks guys for your detail to your work and low prices. I've ad them work on all 4 cars now, we are very satisfied with the out come of each car. I even bought a used car from them -works great. Thanks again Larry F

I am beyond grateful for the amazing service I received here! They fixed my O-ring, gasket cover, and gave my car a tune-up. The work was done thoroughly, professionally, and at a fair price. But what truly touched me was when I noticed later that they went above and beyond, they fixed my bumper without even charging me. That kind of kindness and integrity is so rare to find! Thank you for not only fixing my car but also showing such care. I highly recommend this shop to anyone who wants excellent service and honest people who treat you like family.

I had a problem with my car starting and cranking, and eventually starting smoking. I called highlands auto and they gave me the best price to tow to their shop. They replaced the electrical starter on my car after it went out and they had it repaired and ready to drive within the same day. Fast and efficient. Highly recommend this shop for auto repair. Thanks Highland Auto!
