AC System Inspection and Diagnosis
Every AC repair at May Service starts with a thorough diagnosis. We find out exactly what’s wrong before we recommend anything, so you are never paying to fix the wrong part.
AC Recharge
Low refrigerant is the most common reason a car stops blowing cold air. We’ll recharge your system to the correct level so the problem doesn’t come back next summer.
Compressor Repair and Replacement
We diagnose AC compressor problems accurately and replace them with quality parts built to hold up in Missouri heat.
Condenser Repair and Replacement
A leaking or damaged condenser keeps your system from cooling air properly. We inspect, repair, and replace condensers on all makes and models right here in Warrenton.
Evaporator Service
A faulty evaporator can produce warm air, musty smells, or unwanted moisture inside your cabin. We diagnose and service evaporator issues on all vehicles.
Blower Motor Repair
If air isn’t moving through your vents the way it should, the blower motor is often the problem. We test it and replace if necessary.
AC Leak Detection and Repair
We track AC Leaks and fix it at the source so that your AC starts keeping it’s charge.
Cabin Air Filter Replacement
A clogged cabin air filter restricts airflow and makes your AC work harder than it needs to. It’s one of the quickest and most affordable fixes we offer.
Heater Core Service
If your heat stopped working properly the heater core may be the culprit. We diagnose and service heater core issues on all makes and models.
A Missouri summer without working AC is miserable. If you notice any of the following, bring your vehicle into May Auto Service as soon as possible.
- AC blowing warm or hot air even on the maximum setting
- Weak airflow that doesn’t improve no matter how high you turn the fan
- Musty, chemical, or burning smells coming from the vents when the AC is running
- Clicking, rattling, or squealing noises when the AC is switched on
- AC that cycles on and off rapidly without holding a consistent temperature
- Visible moisture or fluid pooling underneath your vehicle
Your vehicle’s air conditioning system circulates refrigerant through the compressor, condenser, and evaporator to pull heat out of the air inside your cabin and replace it with cold air through your vents. The most common reason it stops working is low refrigerant caused by a slow leak somewhere in the system. Just recharging the refrigerant without finding and fixing the leak is a temporary solution that will leave you right back where you started before summer is over. The second most common cause is a failing compressor, which needs to be properly diagnosed and replaced. At May Service, we always find the root cause first.
When your AC stops working in the middle of a Warren County summer, you want it fixed fast and fixed right. At May Service, we have been doing exactly that for over 30 years. We start with a proper diagnosis every time, so you know the exact issue and what it is going to cost before we do anything. We find the root cause rather than putting a temporary fix on it. With over 200 5-star Google reviews, it’s safe to say Warrenton drivers trust us.
How much does car AC repair cost in Warrenton?
The cost depends on what is causing the problem. A refrigerant recharge is considerably less expensive than a compressor or condenser replacement. We diagnose first and give you a straight estimate before any work begins.
Can you just recharge my AC without fixing a leak?
We can, but we strongly advise against it. If your system is low on refrigerant, there is almost certainly a leak responsible for it. Recharging without addressing the source means you will be back in the same situation within months. We would rather fix it right the first time.
Why does my car AC smell bad?
A musty odor usually points to mold or bacteria buildup in the evaporator or a dirty cabin air filter. A chemical smell could indicate a refrigerant leak in the system. Either way, bring it in, and we will track down the source.
How do I know if my AC compressor is bad?
Loud clicking or rattling noises when the AC is turned on, warm air despite the system running, and the AC clutch not engaging are all common signs of a failing compressor. Our technicians will diagnose it accurately before recommending any replacement.
