HVAC Services North Charleston SC | Call Spanns Heating And Air

Common signs include rooms that are difficult to heat or cool, a noticeable increase in your energy bills, excessive dust, and whistling sounds from your ductwork. Our technicians use specialized tools to perform a thorough inspection and pinpoint any leaks in your system, ensuring your HVAC runs efficiently for the Lowcountry climate.

A stuck reversing valve prevents your heat pump from switching between heating and cooling modes, a crucial function for our variable seasons. You might only get hot or cold air, regardless of the thermostat setting. We diagnose the valve issue, which can often be repaired by clearing debris or, if necessary, replacing the component to restore your system's full functionality.

Our local humidity and salt air can accelerate wear on HVAC components like coils and electrical connections. Regular professional maintenance from Spanns helps prevent failures, improves efficiency, and extends the life of your system. It's the best way to catch small issues, like early signs of duct leaks or valve problems, before they lead to a costly breakdown on a hot or chilly day.
