Air Conditioning Repair Johnson City
A/C blowing hot or not blowing at all? Or does the cool air in your car smells dusty or moldy? Whether your car air conditioning is blowing hot or has strange smells, you can trust that your ASE certified Johnson City A/C auto repair shop will have you cool in no time.
Your Car’s Air Conditioner
During the really hot part of the summer you car’s a/c needs to perform well. Vehicle air conditioning systems depend on just the right amount of Freon in them to operate at peak cold. Sometime we can put the right amount of Freon (R134) back in and you are set for a long while. We will add dye to check your system for leaks. Recharging your a/c system is the quickest and least expensive way to get you back on the road- if that’s all your system needs. The a/c system in your vehicle is similar to the one at your house, but not at 60 mph.
Not an air conditioning system anymore
HVAC is the name and system in your car, truck, or SUV. Heating, ventilation and air conditioning system is what it stands for. This system can remove ice, fog or moisture from the interior glass and sometimes runs in the winter. The system is more complicated with a considerably more advanced sensor and electronics than just ten years ago.
A/C System Recharge
If your car’s a/c just needs an evacuation and recharge because it is a little low, we can do that. We evacuate the auto air conditioner, add Freon back in (to factory settings), add pag oil ( or Polyalkylene Glycol, is a synthetic oil specifically designed for automotive air conditioner compressors) and a little dye. The ultraviolet dye is great at showing us a leak as it circulates through the A/C system. With a black light we can find most leaks right away. Some leaks are so small that it needs to be in the system for a little while going over the bumps and potholes for us to locate the smallest of leaks. Bring it back by for a free check if there are any issues at all.
Compressors can go bad
If your air conditioner compressor is bad we have the expertise to fix it quickly and get you safely back on the road. Often when the compressor goes bad it circulates metal particles throughout the cars air conditioning system and it needs to be flushed along with the compressor, accumulator/dryer and orifice device to do a complete and warrantied repair.
You may also need a new serpentine belt if the compressor has seized and caused damage to the belt.
A/C repairs can be electrical
With a/c controls becoming increasingly complicated, the electrical part of the A/C can cause the system not to work. This could be something as simple as a fuse or a sensor or as a complex wiring issue that will take time and a master mechanic to diagnose. We need to confirm that the system is charged up and eliminated from being an issue before moving to the electrical diagnostic tests. Some auto a/c system issues can be more than one thing. An electrical problem can cause an issue with the Freon charge or the other way around.

Issues with your Cabin Air Filter
Some problems with air flow blockage and smell can be caused by a dirty air filter. A good rule of thumb is to replace your cabin air filter every time you replace the air filter. The cabin air filter is often forgotten but is very important to keep out pollen and dust out of the inside of your car. If it is neglected for very long it can cause issues such as the air conditioner not being able to breathe and cold air not getting through to the car’s interior.
A/C Facts
- Packard was the first manufacture to offer an optional vehicle air conditioner in 1939.
- Cars now use 4 to 5 horsepower to run your A/C (TIP: Having trouble getting up a hill, no power? Turn off the air conditioning in your vehicle).
- There are 6 major parts to a vehicle air conditioning system:
- Compressor: This is the power unit of the A/C system that separates the low-pressure side from the high-pressure side. It takes in low-pressure gas and compresses it into high-temperature/high-pressure gas. Typically, the compressor is mounted to the front of engine and driven by serpentine belt
- Condenser: The condenser reduces the temperature of refrigerant while it maintains high pressure. The refrigerant then changes from gaseous state to liquid state as it cools. The condenser is typically mounted in front of the vehicle behind the grill so air will keep it cool.
- Dryer: The dryer removes water from the refrigerant using a desiccant (drying agent) and also has some system-filtering properties. The dryer is mounted on the high-pressure side of the vehicle's air conditioning system, between the condenser and metering device
- Metering Device: The metering device can be either an expansion valve or fixed orifice tube. The metering device lowers refrigerant pressure, which then quickly drops the temperature of the refrigerant. The metering device is normally mounted on the high-pressure side of the car's A/C system, between the dryer and the firewall
- Evaporator: The evaporator helps refrigerant change back to a gaseous state causing a cooling effect. The cabin air is cooled and dried as it blows across the evaporator. This is the only A/C component mounted inside the passenger compartment, behind the dashboard (which often takes hours to get to and replace)
- Refrigerant: Most refrigerant used in newer vehicles is R-1234yf which produces less greenhouse gases (European vehicles all use this refrigerant). Majority of domestic vehicles use R-134a. Some older vehicles may still use R-12 but should be replaced.
There is no need to take you vehicle back to the dealer when we can take care of your car, truck or SUV’s air conditioner service and repairs.
