Restore Cool Air Before Summer Peaks

AC repair and recharge services from Jersey Auto Repair keep your vehicle comfortable throughout North Brunswick, New Jersey.

When your air conditioning blows warm air during a humid July afternoon in North Brunswick or takes too long to cool down your cabin after your car has been parked in the sun, the issue could be low refrigerant, a failing compressor, or a leak in the system. Jersey Auto Repair diagnoses AC performance by checking refrigerant levels, inspecting hoses and connections, and testing compressor operation. This process identifies whether your system needs a simple recharge or component repair to restore cooling performance.

AC service covers recharging refrigerant to factory-specified levels, replacing compressors and condensers, and sealing leaks that cause gradual loss of cooling. The team explains what's affecting your system and provides a written estimate before beginning repairs, so you understand the work and the expected improvement in cabin temperature.

If your AC isn't keeping up with New Jersey heat and you need reliable cooling again, contact Jersey Auto Repair in North Brunswick.

What Fixes Weak or Warm Airflow

Service begins with a pressure test to measure refrigerant levels and detect leaks in hoses, seals, or the condenser. In North Brunswick, where summer temperatures regularly climb into the 80s and 90s, a properly functioning AC system makes a noticeable difference in comfort during daily commutes and family trips.

After the repair is completed, your AC blows cold air within seconds of starting the vehicle, the cabin cools quickly even on hot days, and airflow remains strong across all vent settings. You no longer feel warm air mixed with cool, and humidity inside the cabin drops noticeably.

Jersey Auto Repair recharges AC systems using R-134a or R-1234yf refrigerant depending on your vehicle's design. The service includes replacing cabin air filters, inspecting blower motor operation, and checking electrical connections to the compressor clutch. If your AC system has a major leak or requires condenser replacement, the team provides a cost breakdown and timeline before scheduling the work.

Answers to common AC service questions

Drivers throughout Middlesex County often ask similar questions about AC performance, refrigerant types, and when to schedule service before the summer rush.

Why is my AC blowing warm air?
Warm air typically results from low refrigerant, a failing compressor clutch, a clogged expansion valve, or a leak in the system. Jersey Auto Repair uses a pressure gauge and leak detection dye to locate the issue and determine whether you need a recharge, a seal repair, or component replacement.
How long does an AC recharge last?
A properly sealed system maintains refrigerant levels for several years. If your AC loses cooling within a year of recharging, you likely have a slow leak that needs to be located and repaired before adding more refrigerant.
What is the difference between R-134a and R-1234yf refrigerant?
R-134a is the older refrigerant used in vehicles manufactured before 2017. R-1234yf is a newer, more environmentally friendly refrigerant required in most vehicles built after 2017. The two are not interchangeable, and using the wrong type can damage your AC system.
When should I replace my cabin air filter?
Cabin air filters should be replaced every 12,000 to 15,000 miles or when airflow from the vents weakens noticeably. A clogged filter reduces cooling efficiency and allows dust and pollen to circulate inside the vehicle.
Why does my AC work fine at highway speeds but not in traffic?
This symptom often indicates a failing condenser fan or a refrigerant level that's slightly low. At highway speeds, airflow through the condenser keeps the system cool, but in stop-and-go traffic, the fan must provide that cooling. Diagnosis confirms whether the fan motor or relay needs replacement.
