Common Questions

How can I tell if my air conditioner in Carthage has a refrigerant leak?

Common signs in our area include your AC running constantly but not cooling effectively, ice forming on the refrigerant lines or evaporator coil, and a noticeable spike in your energy bills. If you suspect a leak, it's important to call a professional like Gunlock Heating & Air right away. We use specialized tools to locate and repair the leak, then recharge your system to the manufacturer's exact specifications, restoring efficiency and cooling power.

Why do my AC's condenser coils get so dirty in Carthage, and how often should they be cleaned?

Carthage's seasonal pollen, cottonwood, dust, and grass clippings can quickly clog the outdoor condenser unit, making it work harder and use more energy. We recommend a professional cleaning at least once a year, ideally in the spring before peak cooling season. During our routine maintenance visit, we carefully clean the coils, straighten the fins, and clear debris from around the unit. This simple service can significantly improve efficiency, prevent breakdowns, and extend the life of your system.

What's included in a Gunlock Heating & Air seasonal maintenance check for my HVAC system?

Our comprehensive Carthage-area maintenance check is designed to catch and prevent local issues. We inspect for refrigerant leaks, thoroughly clean condenser and evaporator coils, check electrical connections, calibrate your thermostat, lubricate moving parts, and ensure proper airflow. This proactive service helps your system run smoothly, improves indoor air quality, and can identify small problems—like a developing leak or dirty coil—before they lead to a complete breakdown on a hot summer day.
