Shelly Oil - Elizabethtown's Licensed HVAC Services

First, check the basics: ensure it's set to 'heat' and the temperature is above the current room reading. If problems persist, like unresponsive controls or incorrect readings, it's time to call Shelly Oil. Our technicians can diagnose issues from faulty wiring and dead batteries to more complex system incompatibilities, ensuring your thermostat accurately controls your HVAC system.

Fluctuating boiler pressure is a common issue in our area, often due to a faulty pressure relief valve, a leak in the system, or needing a repressurization. While low pressure may cause your system to shut off, high pressure can be a safety concern. Our experts at Shelly Oil can safely inspect your boiler, identify the root cause, and perform the necessary repair or adjustment to restore safe, efficient operation.

Regular professional maintenance is the best defense against the thermostat and boiler issues we often see. Our preventative service includes checking and calibrating your thermostat, inspecting boiler pressure and components, cleaning essential parts, and identifying small problems before they lead to a breakdown. This proactive care improves reliability, efficiency, and can extend the life of your entire heating system.
