A/C and Heating Repair in Killeen & Harker Heights

Your vehicle’s air conditioning and heating systems aren’t just about comfort—they’re about safety and drivability too. A failing A/C can make summer travel unbearable, while a malfunctioning heater can prevent windshield defrosting in colder months. At Mayo Autoworks 2 and Mayo Autoworks 3, we know how quickly Texas weather can turn, which is why we offer fast, reliable A/C and heating diagnostics and repairs at both of our locations. 


Using advanced diagnostic equipment, our ASE-certified team will inspect refrigerant levels, test system pressure, and identify issues in your A/C lines, blend doors, thermostats, or cabin filters. We service all vehicles, including diesel trucks and imported models, and we’re proud to stand behind our work with warranties and partnerships that deliver peace of mind.


Heating problems can also point to bigger concerns like coolant leaks or engine thermostat issues. That’s why ignoring a weak heater or fogged-up windows can lead to costly repairs if not addressed early. Whether it’s a faulty control module or something as simple as a blocked vent, our locations provide honest diagnostics and clear recommendations. 


As a certified NAPA AutoCare Center and RepairPal shop, we’re dedicated to accurate service, transparent pricing, and getting the job done right the first time. We serve drivers across Killeen, Fort Hood, Harker Heights, and surrounding areas with fast turnarounds and a reputation for reliability.
