Great Bear Renewable Energy | Local HVAC Services in Lunenburg, VT

Common signs include uneven heating between rooms, excessive dust, and whistling sounds from ducts. As your local HVAC experts, we perform a professional duct blaster test to precisely measure leakage. Sealing these leaks is a priority in our older Vermont homes, as it can improve system efficiency by up to 30%, directly lowering your energy costs.

Vermont's extreme temperature swings demand a perfectly sized and installed system. An improperly installed heat pump can short-cycle, struggle in deep cold, and waste significant energy. Our technicians are certified and follow meticulous, manufacturer-specific procedures. We ensure correct refrigerant charge, optimal thermostat placement, and proper airflow—guaranteeing the reliable, efficient performance you need for our climate.

Our diagnostic goes beyond a basic check. We assess your entire system: measuring airflow at each register, checking refrigerant levels, inspecting electrical components, and evaluating ductwork integrity. This holistic approach, tailored for local issues like duct leaks and past installation errors, gives us a complete picture. We then provide a clear, honest report with prioritized recommendations to fix inefficiencies and boost your comfort.
