Climate Control Systems

When it starts to get warm outside, there’s nothing more frustrating than to turn on your vehicle’s air conditioner to find that warm or no air comes out. This can be the result of any number of issues. That’s why you should trust your auto air conditioning repair and service needs to the auto technicians at MB Automotive in Bay Shore, New York.

We service Volvo, foreign and domestic vehicles Climate Control Systems. Heating & Air conditioning.

If you are having a problem with your vehicle’s air conditioner, we start by looking to see if any of the belts are loose. Many times the issues with car air conditioners are the results of leaks in the cooling system. In those cases, the leak can be found by performing a dye injection leak test, and if needed, we evacuate and recharge your car’s air conditioning system.

Car Heating System Repair – Keeping Your Car Warm in the Winter

Your vehicle’s heater looks like a much smaller version of the radiator. As heat is produced in the engine, it is absorbed by the antifreeze/coolant and then circulated through the heater core before it goes back to the radiator. Getting the warm air into your car is done by a fan that blows air over the heater core.

If the heater core becomes clogged, the heater won’t work properly and you will need to have it repaired. If you see coolant in the interior of your vehicle or you smell coolant when your heater is running, there is most likely a leak in the system. The ASE-technicials at MB Automotive can diagnose and fix your car heating system so you and your passengers remain nice and warm.

Air Conditioning Repair Checklist

1. Check if A/C component mounting bolts are in place and tightly secured?
2. Check that caps are installed on the A/C system service ports? This keeps out dirt, and also provides a seal for the refrigerant.
3. With the engine running, check the compressor clutch engages when the A/C is switched on. If it doesn’t, this usually indicates a low (or empty) refrigerant condition or an electrical problem. Also, listen for rapid clicking or cycling noises at the compressor when the A/C is switched on. If this is happening, it could also indicate low refrigerant or some other problems. Have it checked by your service technician. (Note: Some A/C systems prevent compressor clutch engagement in low temperatures, typically at or below 40° F.)
4. With the engine running we check if the A/C switches off, and we listen for knocking or rumbling sounds in the vicinity of the compressor. This could indicate a failing compressor clutch, and/or loose mounting hardware.
5. We check all belts for cracks, wear, and glazing. Have them replaced at the first sign of any of these conditions. Also, check for belts that vibrate while the engine is running and the A/C is on. This may indicate a belt that needs to be tightened or a defective automatic belt tensioner.
6. We examine all A/C and cooling system hoses for cuts, abrasion, weak spots, and signs of leakage. Leakage from A/C system hoses is often indicated by an accumulation of dirt and oil, particularly at connections and fittings.
7. Check that the condenser (in front of the radiator) is free of any obstructions, such as leaves or insects. This could reduce airflow, resulting in reduced A/C performance.
