Lexco Comfort Services | Emergency HVAC Repair in Lexington, SC

A great first step is to check your home's Wi-Fi router and ensure the thermostat has a strong signal. Often, a simple router reboot can resolve the issue. If connectivity problems persist, it could be related to the thermostat's wiring, its internal software, or compatibility with your HVAC system. Our technicians are experts in smart home integration and can diagnose the specific cause to get your Lexington home's comfort schedule back on track.

For most Lexington homes, we recommend checking your air filter every month and replacing it at least every 90 days. If you have pets, allergies, or are during high-pollen seasons, you may need to change it as often as every 30-45 days. A clogged filter makes your system work harder, reducing efficiency, increasing bills, and circulating dust. Regular filter changes are one of the easiest and most important things you can do for your HVAC system's health.

Absolutely. A severely clogged air filter restricts airflow over the evaporator coil, causing it to get too cold and freeze. This is a common issue we see in Lexington, especially during our hot, humid summers. If you notice reduced cooling, ice on the refrigerant lines or the unit itself, or water leakage, a dirty filter is a likely culprit. Shut the system off to let it thaw and call us. We'll replace the filter, check for any other issues, and restore proper, efficient cooling to your home.
