Tradewinds HVAC: Certified HVAC Services Serving Portsmouth, VA 23703

Our maintenance service is a thorough check-up designed to prevent problems before they start. We'll inspect and clean key components, check refrigerant levels, and test system controls. For Portsmouth homes, we pay special attention to air filters, as our coastal humidity can lead to faster clogs, and to heat pump components that work hard year-round. This proactive care helps improve efficiency, extend your system's life, and reduce the chance of unexpected breakdowns.

Nitrogen brazing is a critical step we use when installing or replacing refrigerant lines. By flowing nitrogen through the lines while we braze (or solder) the copper connections, we prevent the formation of oxidation scale inside the pipes. This 'copper flaking' can circulate through your new system, causing damage to valves and the compressor over time. It's an extra step that takes a bit longer, but it protects your investment and helps ensure your new HVAC system runs reliably for years to come.

That's a common issue here, often related to the reversing valve. This valve is what allows your heat pump to change modes. In our coastal climate, corrosion or electrical issues can cause it to stick or fail. When I diagnose this, I'll check the valve's solenoid coil, electrical connections, and pressure differentials. Often, a thorough cleaning or a minor repair can solve it, but if the valve itself is faulty, I'll recommend a precise replacement to restore your system's full function efficiently.
