Stewart's Heating & Air Conditioning - Florence's Reliable HVAC Services

In Florence, common causes include Wi-Fi signal interference, outdated thermostat firmware, or a faulty common wire (C-wire) not providing constant power. Our technicians diagnose the specific issue, whether it's a simple settings adjustment, a firmware update, or installing a C-wire to ensure reliable, year-round connectivity for your comfort.

Dirt and dust on the evaporator coils act as insulation, preventing them from absorbing heat effectively. This forces your AC in Florence to run longer and harder, leading to higher energy bills, reduced cooling power, and increased strain that can cause premature system failure. Our professional cleaning restores efficiency and protects your investment.

Our comprehensive maintenance includes inspecting electrical connections, checking refrigerant levels, cleaning condensate drains, and—critically—thoroughly cleaning both the indoor evaporator and outdoor condenser coils. This proactive service directly addresses Florence's common coil and performance issues, ensuring your system runs efficiently, reliably, and helps prevent smart thermostat communication errors.
