HVAC Repair Barrington NH | Call Cote & Son Hvac

Ice buildup on your outdoor unit, especially common during our humid summers, is often a sign of restricted airflow or low refrigerant. This forces the system to work harder, reducing efficiency and potentially causing a breakdown. It's important to address it promptly to prevent further damage. Our technicians can diagnose the root cause—whether it's a dirty filter, blocked coils, or a refrigerant leak—and perform the necessary repair to restore proper function.

Signs of leaky ducts include uneven heating or cooling between rooms, higher-than-normal energy bills, excessive dust, and your HVAC system running constantly to maintain temperature. Leaks are common in older homes and force your system to work overtime. We perform thorough duct inspections and use sealing techniques to close leaks, which improves comfort, reduces energy waste, and extends the life of your HVAC equipment.

Our seasonal tune-up is designed to catch and prevent the issues we see often in Barrington. It includes cleaning condenser coils to prevent ice, checking refrigerant levels, inspecting electrical components, testing system controls, and examining ductwork for signs of leaks or blockages. This proactive maintenance helps your system run efficiently, lowers the risk of unexpected breakdowns, and can significantly reduce your energy costs.
