HVAC Repair Westerville OH | Call Master Air

If you notice ice or frost on your indoor evaporator coil in Westerville, it's a sign of a problem like low refrigerant or restricted airflow. First, turn your system off to let the ice melt. Continuing to run it can cause further damage. Our NATE-certified technicians can diagnose the root cause—whether it's a leak, a dirty filter, or a failing component—and perform the necessary repair to restore efficient cooling and prevent a recurrence.

The decision depends on the age, efficiency, and reliability of your current system. If your furnace or AC is over 15 years old, requires frequent repairs, or causes uneven temperatures and high energy bills, replacement is often the more cost-effective long-term solution. Since 1987, our experts have provided honest assessments for Westerville homeowners. We'll explain your options clearly, helping you choose a repair or a new system installation that fits your home's needs and your budget.
