Jeremiah Johnson Heating and Cooling | Trusted HVAC Services in Charleston, WV

Dirty evaporator coils are a very common issue here in Charleston. Over time, dust, pet hair, and debris from our environment build up on the coils inside your air handler, acting like insulation. This prevents the coils from absorbing heat from your home's air effectively, forcing your AC to run longer and work harder. This leads to higher energy bills and reduced cooling. A professional cleaning as part of a routine maintenance visit from our team can restore efficiency and prevent strain on your system.

Smart thermostat connectivity problems are frequent, often due to our local Wi-Fi network environments or power issues. First, try a simple reboot of the thermostat and your home router. Ensure the thermostat's base is securely connected to its wall plate, as a loose connection can interrupt power. Check for any firmware updates for the thermostat model via its app. If problems persist, it could be a wiring issue at the HVAC system's control board or an incompatible C-wire (common wire) providing constant power. Our technicians can diagnose and resolve these wiring or compatibility issues to restore your remote control and scheduling features.

We strongly recommend enrolling in a seasonal maintenance plan. For Charleston residents, this includes a comprehensive spring tune-up for your AC, focusing on cleaning those critical evaporator and condenser coils, checking refrigerant levels, and ensuring all components are in good shape before summer heat arrives. In the fall, we perform a heating system check. These regular visits allow us to spot minor issues—like the beginnings of coil dirt buildup or potential wiring concerns that could affect your thermostat—before they lead to breakdowns or inefficiency. It's the most effective way to maintain comfort, lower bills, and extend your system's life.
