Moore HVAC Repair | Evaporator Coil & Thermostat Fix | L & S Heating & Air

In our Moore climate, a frozen evaporator coil is often caused by restricted airflow from a dirty air filter, low refrigerant levels, or a failing blower fan. This prevents the coil from absorbing heat properly, causing condensation to freeze. Our technicians will diagnose the root cause—whether it's a simple filter change or a refrigerant leak repair—to get your cooling system running efficiently again and prevent costly damage.

Smart thermostat issues often stem from incorrect wiring, compatibility problems with your existing HVAC equipment, or Wi-Fi connectivity drops. As your local HVAC experts, we can verify compatibility, ensure proper installation and configuration, and troubleshoot any wiring or power issues specific to your Moore home's system. This ensures your thermostat communicates correctly with your furnace and AC for optimal comfort and energy savings.

Preventive maintenance is key to avoiding the evaporator coil freezes and thermostat glitches common in our area. We recommend biannual tune-ups, which include cleaning coils, checking refrigerant levels, calibrating thermostats, and inspecting electrical connections. This proactive service helps your system run smoothly through Oklahoma's extreme seasons, improves efficiency, and catches small issues before they lead to a complete breakdown and an uncomfortable home.
