Don Hall Heating & Cooling: Trusted HVAC Repair Serving Graham 27253

First, check your thermostat to ensure it's set to 'cool' and the temperature is set lower than the current room temperature. Then, check your air filter; a dirty filter in our Graham climate can severely restrict airflow and cause the system to freeze up or not cool effectively. If these simple checks don't help, it's time to call us for a professional diagnosis to prevent further issues.

Signs of a faulty thermostat include your HVAC system not turning on/off, temperature readings being inaccurate, or a blank display. For Graham homeowners, we often see issues arise from aging thermostats or power surges. We can test your current unit and discuss repair or upgrade options, including modern programmable or smart thermostats that can improve comfort and efficiency in our local weather.

One of the most frequent calls we get in Graham during summer is for reduced cooling, often due to refrigerant leaks or frozen evaporator coils. Our intense heat and humidity put extra strain on systems. Low refrigerant or a dirty coil can cause the coil to freeze, blocking airflow. Our technicians will locate the source of the issue, make the necessary repair, and ensure your system is charged correctly for optimal performance.
