Auto A/C and Heater Service You Can Trust in Smyrna, DE
Stay Comfortable Year-Round with Expert HVAC Service

Signs Your A/C or Heating System Needs Attention
A/C Blows Warm Air
If your air conditioning is no longer producing cold air, it could be due to low refrigerant levels, a failing compressor, or a refrigerant leak. Without the proper amount of refrigerant or if there's a blockage in the system, the A/C cannot cool effectively. Simply topping off the refrigerant may not solve the issue if there is an underlying leak or component failure.
Heater Isn’t Warming Up
When the cabin stays cold even after the engine reaches temperature, the problem could involve the heater core, thermostat, or coolant circulation. These issues may also impact the engine’s cooling system.
Weak or No Airflow
If air is barely coming through the vents or only flows at certain speeds, the blower motor or resistor could be failing. In some cases, airflow is blocked by a clogged cabin air filter or obstructed ductwork. Reduced airflow not only affects cabin comfort but also limits your ability to clear the windshield or maintain a consistent temperature.
Strange Smells or Foggy Windows
A musty or sweet odor coming through the vents could signal mold growth inside the evaporator case or a leaking heater core. Fog forming on the inside of the windows, especially when the heat is on, often indicates moisture inside the system. These conditions can reduce air quality and impair visibility if left unresolved.
Unusual Noises from the Vents
Noises such as clicking, rattling, or buzzing when the HVAC system is on may be caused by debris in the fan housing, broken fan blades, or failing blend door actuators. These components help control airflow direction and temperature, and when they malfunction, they can lead to uneven cooling or heating and persistent noises every time you use the system.

Understanding R-134a and R-1234yf Refrigerants
As vehicle A/C systems have evolved, so have the refrigerants they rely on. Most vehicles built before 2017 use R-134a, a reliable and widely available refrigerant. Newer models often require R-1234yf, an environmentally friendlier option designed to meet stricter emissions standards. At Pristine Motorsports, we’re equipped to handle both using dedicated recovery and recharge stations to ensure accurate service without cross-contamination. Whether your vehicle needs a top-off, a leak repair, or a full system recharge, we have the tools and expertise for the job.
