Highly recommend Kool2U! Their responsiveness was great and the service was evenHighly recommend Kool2U! Their responsiveness was great and the service was even better. I had a repeating automobile A/C issue and got tired of going to repeatedly to brick and mortar places just to wait all day for a fix that inevitably turned out not to fix the problem after about a month of use.
Excellent and courteous service. Expert level of diagnostics for an electrical short that caused battery malfunction and vehicle not to shift out of park.
Keep me informed of their progress and solution. Would recommend this establishment for anyone needing reliable automotive services with fair and competitive pricing. No price gouging or upselling. Earnest S.

I can’t say enough good things about this company! Their mobile A/C repair team came all the way out to Bandera, Texas to repair, recharge, and service my entire air conditioning system right at my location. The technician was extremely professional, courteous, and knowledgeable, and the administrative staff made scheduling and communication effortless.
They diagnosed the issue quickly, explained everything clearly, and had my system running ice-cold again in no time. It’s rare to find this level of service and integrity nowadays; especially with mobile automotive repairs.
I highly recommend this company to anyone needing mobile A/C repair or any other automotive service. They truly go above and beyond for their customers! Robert S.

The MaxKool AC Leak Detection System
A Leap Ahead In Auto AC Leak Detection
Exclusive To Kool2U Auto Repair Service!
Your local auto repair shop and dealership service department use a system for diagnosing your vehicles AC system that was developed in the 1950's. It Involves vacuuming down the refrigerant or freon in your cars AC System. Then injecting oil & dye into the system with nitrogen hoping to "sniff out" or expose the refrigerant leak with a blacklight when the AC system.
So what's the problem?
It produces a kind of hit or miss scenario that tends to find the big leaks but not small, micro leaks in your vehicles AC System. So the obvious leaks in your cars AC system get repaired but it also means that you get to go back & do it all over again in a few days or weeks.
In 2018 most car ac systems switched to R1234yf Refrigerant (Freon). This raised the cost to evacuate and recharge your vehicles ac system up to 10 times higher than the old R134b refrigerant. If your vehicles AC system is an R12 Refrigerant System (70's & 80's) it can be as much as 50X more expensive because it is not produced anymore. It's like finding gold in your grandfather's garage!
What does this mean for you?
Maybe you get lucky the first time. Far too often it means repeated trips to the shop until they find the root in your cars ac system issues.

Common Reasons Your Vehicles AC Isn't Working Properly

Most often this issue is caused by an ac refrigerant (Freon) leak (R12, R134a, or R1234yf). Your cars ac relies heavily on the refrigerant (Freon) to cool the vehicle. Without sufficient ac refrigerant, the other auto ac components will be unable to function. An Auto AC leak can occur at any time but most often it is due to a hole in a connection, ac hoses, ac compressor, ac condenser, or a ruptured ac evaporator. Unlike an oil leak, unfortunately, refrigerant (Freon) leaks are difficult to identify (R12, R134z, or R1234yf). This is because your auto ac refrigerant is meant to evaporate when exposed to the environment.
Solution: A Kool2U certified auto ac repair specialist will need to add a fluorescent leak tracer dye and ac refrigerant to the system. Once added, your auto ac repair technician will run the car ac and using a Kool2U's MaxKool AC Leak Detection System . Your Auto AC Repair Technician will then be able to identify your auto ac leak to begin repairs and finally perform an ac evacuation and ac recharge to once again blow cold air.
This issue isn’t as clear cut as hot air coming through the vents. A knowledgeable auto ac repair technician will need to eliminate the possible causes by checking several components first. The auto ac repair technician may begin checking for:
-
A blown fuse or bad relay – If the ventilation fuse blows there will be no power to the ac blower motor preventing air from blowing through the vents. Likewise, a bad ac relay can also be the culprit since the relay takes the small electrical current and uses it to regulate the larger current needed for ventilation.
-
Damage to the auto ac blower motor or blower resistor – The ac blower motor is what pushes the air through the vents in the car, similar to a fan in your home. Auto AC Blower motors that have malfunctioned due to wear or age will prevent air from coming through the vents. Similarly, the ac blower resistor works with the ac blower motor to control the level of how much air is produced to flow through the vents (low, medium, high) based on your preference.
-
Blocked air intake – Auto AC's have two areas where air enters your cars ac One is where air enters your cars ac is through vents by the lower half of the windshield and the other is the air that is recirculated from inside the cabin. If either of the ac air intake areas is blocked from a clogged filter or other debris, your cars ac vents may blow little to no air.
-
Damaged belts and hoses – An automotive air conditioning system is equipped with many ac hoses and belts that operate your cars ac system. Any sort of ac leak, detachment, or blockages will prevent proper airflow from your cars ac vents.
Most often this issue is due to low ac refrigerant. When there is not enough ac refrigerant (Freon) in the system the pressure is reduced which prevents the clutch from triggering the ac compressor to begin its cycle. If enough ac refrigerant is in the system it could also be caused by:
-
Blocked or Failed Condenser – Your cars ac condenser is the device that takes the ac refrigerant from its gaseous state by removing the heat and transforming it back into a liquid state. If your cars ac condenser has a blockage or is otherwise damaged, the air coming through the vents will not be cold.
-
Failed Clutch Switch – If this component is not functioning, the ac compressor will be unable to operate, thus preventing it from condensing the liquid refrigerant into gas.
When you turn on your cars ac and an noxious smell of mildew hits your nostrils, it’s because of the growth of bacteria in your cars ac system. This is common with automobiles that seldom use the auto AC, are older, or that frequently use the maximum ac setting (due to extra moisture in the unit). Bacteria, mold, fungi, and other micro-organisms may develop behind the dashboard on your cars ac evaporator. This growth produces a foul odor that comes out of the vents.
Solution: Auto AC Air filters can collect dirt, water, dust, and other pollutants and after some time producing an odor. Replacing your cars ac air filter will help combat this issue. If replacing the filter does not eradicate the stench, a Kool2U Auto AC Repair technician will need to add an anti-bacterial solution into your car's ac evaporator area to kill mold and other contaminants from the ac system.
Anytime your car makes a noise that wasn’t there before could be a sign of trouble. Auto AC systems are relatively quiet when in use. When you turn on your car ac and hear rattling, banging, or other unusual sounds, it’s normal to feel a bit nervous about what is causing the issue. It could be as simple as leaves or other road debris blocking the ac system producing all sorts of unusual noises. It could also indicate a major component of your cars ac could be in failure and in need of repair. If a bearing is worn out your car ac it will produce a grinding or squealing sound. A rattling sound could indicate your cars ac compressor’s clutch has failed.
Solution: Continuing to use your car AC may only make things worse. Call Kool2U's Mobile Auto A/C Repair Specialists to perform a thorough inspection. A thorough inspection your car ac will be able to determine if a major component is in failure and whether your cars ac will need to be repaired.
Bacteria builds up on your car ac evaporator coil in the AC heater box located under your dashboard. The bacteria from airflow mixes with the condensation from the car ac coils, creating a slimy film on the AC fins and producing a moldy smell. After time, the film builds up and can clog the drain line. The drain line is a rubber hose that begins in the ac evaporator heater box, goes through the floor, and to the undercarriage to remove excess moisture. Once plugged, water from the condensation fills up the ac heater box and begins dripping out and onto the floor of the vehicle, typically on the passenger side.
Solution: If you notice the floor of your automobile is damp, don’t hesitate in contacting Kool2U Mobile Auto AC Repair and schedule an appointment. A Kool2U Auto AC Repair technician will need to determine what has caused the drain line to become clogged and repair or replace the hose as necessary.
When you’re driving your car and the ac suddenly goes from comfortably cool to horribly hot, you know there’s a problem with your car's ac system. It’s possible that the ac expansion valve that dispenses the correct amount of ac refrigerant (Freon) to the ac evaporator has failed. A blocked ac expansion valve prevents the refrigerant (Freon) from reaching the ac evaporator and, if moisture is present, causing the ac valve to freeze.
Solution: Your car's ac should be cold. If it’s not a Kool2U certified auto ac repair technician will need to properly test the ac system’s pressure and inspect components for blockages or malfunctions.
No matter what symptoms your car ac may be experiencing, a certified Kool2U auto ac repair specialist knows how to properly diagnose car AC problems and how to properly repair your vehicle's ac to properly function. Need service on your Auto AC for repair?
