Expert AC & Heating Repair
in Elgin, IL

We recommend annual AC inspections before summer. The cabin air filter should be changed every 12,000-15,000 miles. Refrigerant doesn't need regular replacement unless there's a leak, but the system should be checked annually for optimal performance and to catch issues early.

AC recharge involves evacuating old refrigerant, checking for leaks, replacing the receiver/dryer if needed, pulling vacuum to remove moisture, and adding the correct amount of fresh refrigerant and oil. Simply adding refrigerant without fixing leaks provides only temporary relief.

Musty odors typically indicate mold or bacteria growth on the evaporator core due to moisture accumulation. This is common in humid climates. We can clean the system with antimicrobial treatments and replace cabin air filters to eliminate odors and improve air quality.

Yes, and you should! Running AC in winter helps maintain seals and lubricates components. Your defroster actually uses the AC system to remove humidity from the air, which helps clear foggy windows faster. Running it periodically prevents seals from drying out.

Yes, water dripping from the passenger side is normal condensation from the evaporator and indicates your AC is working properly. However, if you notice colored fluids or excessive water inside the vehicle, this could indicate a clogged drain tube or other issue requiring service.

Most vehicles built after 1994 use R-134a refrigerant, while newer vehicles (2013+) may use R-1234yf for environmental reasons. Different refrigerants require different equipment and procedures. Using the wrong refrigerant can damage your system. We identify your vehicle's requirements and use only approved refrigerants.

Intermittent AC operation often indicates electrical problems like faulty pressure switches, temperature sensors, or control modules. Low refrigerant, clutch bearing wear, or expansion valve issues can also cause cycling problems. Our diagnostic approach identifies the root cause of intermittent operation.

Run your AC monthly year-round to keep seals lubricated, replace cabin air filters regularly, keep the condenser clean by removing debris, park in shade when possible, and address unusual noises promptly. These simple steps extend AC life and maintain performance.

AC recharge simply adds refrigerant to a low system, providing temporary relief if there's a leak. AC repair addresses the underlying problems like leaks, failed components, or electrical issues. Proper repair ensures long-lasting cold air, while recharge without fixing leaks wastes money.

Gradual cooling loss typically indicates small refrigerant leaks, dirty condenser fins, worn compressor, or aging system components. Unlike sudden failure, gradual loss allows time for proper diagnosis and repair. Regular maintenance helps identify developing issues before complete failure occurs.
