Car AC repair

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 Moncur's Automotive 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.


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's auto AC heat repair needs to keep your cooling system operating at its best. Dial 480-213-6075 to learn more about how we can restore your air conditioning.


Common Automotive AC Repair Services


1234YF Vehicle AC Refrigerant
Our facility is equipped to handle a variety of auto AC repair services, including the latest 1234YF freon recharge for your car, truck, or jeep. This refrigerant, mandatory in all vehicle AC systems manufactured after 2021, offers an environmentally friendly way to keep your vehicle's cabin cool.

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 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.

Kerry was professional, polite and knowledgeable. He explained everything clearly and thoroughly. I appreciate his care and patience with me as a new customer. I trust that he has the expertise to diagnose items others miss, while not upselling you for repairs or parts that you do not need. I appreciate his ability to use his experience in solving intermittent, or tricky issues. I would not hesitate to bring my cars to his location again or to recommend friends and family to his shop. Everything was straightforward and handled with courtesy. I look forward to working with Moncur's in the future.

Moncur's was great! A/C went out on my car so I decided to take it to AAA to get diagnosed. They told me since the leak was so small that in order to find it, they wanted to charge me $450 to re-charge my A/C system up with refrigerant & dye, and then come back when the system was empty again so they could find the leak and diagnose what needed to be repaired/replaced. Then they were going to charge me that same price for refrigerant, AGAIN, on top the cost to fix the leak. Seriously? Moncur's found the leak by pressurizing the system overnight with dye and replaced the leaking condenser quickly. Had my car back to me working again within 2 business days and a 2 year parts,service, and labor warrenty. Excellent customer service also. Take you vehicle here to this trusted family business and not AAA. Thank you Moncur's!
