Automotive Air Conditioning & Heating Parts for Buses and Commercial Vehicles
When it comes to automotive air conditioning & heating parts, reliability isn't optional, it's essential. At O2 Cool Manufacturing LLC, we design, engineer, and manufacture climate control components that keep vehicles running comfortably in every season. From school buses, transit buses, and commercial fleets to specialty and emergency vehicles, our systems are built to deliver performance, durability, and comfort where it matters most. We build full HVAC systems and components that integrate with your vehicle platform. Whether you're repairing an existing system or outfitting a new build, our automotive air conditioning parts and automotive heating parts are engineered for exact fit and long-term dependability.
OEM and Aftermarket Parts
We offer complete lines and full ranges of OEM parts built by the brand itself or authorized third-party manufacturers. OEM parts are the original components of your system. They usually guarantee a perfect fit and optimal performance because they are designed specifically for the model.
We also carry quality parts from aftermarket manufacturers. These parts are compatible with various brands and models and often function as replacement options. Although their specifications and performance can vary, they provide a wider range of options and often cost savings.
We can service your HVAC system with the following:
General HVAC parts
- Electrical fans for all sizes and mounting configurations
- Blower assemblies for most aftermarket applications
- Hoses, fittings, clamps, and cages for all manufacturers
- Electrical and pressure switches
- Replacement controls and boards
Automotive air conditioning parts
- OEM compressors
- Replacement receiver driers and expansion valves
- A/C compressor mounting kits
Automotive heating parts
- Booster pumps for 12 V rear heater assemblies

Bus Air Conditioning Parts for School, Transit, and Shuttle Fleets
O2 Cool designs and builds air conditioning and heating systems for school buses, public transit buses, and shuttle buses, so we stock the parts that keep those systems running. Fleet managers can source compressors, electrical fans, hoses, switches, and replacement controls from the same team that engineered the system. Tell us your bus make, model, and current HVAC setup, and our team will match the right OEM or aftermarket part.
