Air Conditioning Repair For Cars and Trucks


Restoring Comfort with Long Hill Auto Service in Millington

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 Long Hill Auto Service in Millington, where we'll swiftly restore your AC's performance. Reach out to us now at 908-647-7984 or drop by our shop at 1905 Long Hill Rd, Millington, NJ.



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 Long Hill Auto Service 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 908-647-7984 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.

The owner is honest as the day is long. I brought my car in recently because of a dashboard light that said "AWD System Malfunction, 2WD Mode Engaged, Visit your Dealer." Scared the crap out of me. While I had used Long Hill in the past and was satisfied with their work, I wan't completely comfortable having them, as opposed to my "Dealer," address this issue. Long story short, the owner diagnosed it, told me it was merely a problem with the sensor on the dashboard (or something like that...I'm not too savy when it comes to auto repairs), fixed it, and charged me nothing. I'm now a customer for life!

I was driving to see my dad for Father’s Day yesterday. Got on 78 and my car started jerking and loosing steam. It was 4:15pm about 45 mins before the shop closed, they took a look at my car and were able to fix it by 6pm so I was able to drive my car back home that day- it was amazing! So thankful they were able to help me out or else I would have to miss work Monday as no shops are open Sunday’s. Thanks again!!
