HVAC Services Walterboro SC | Call M&D Mechanical

Improper installation is a frequent issue that leads to uneven cooling/heating, high energy costs, and frequent breakdowns. At M&D Mechanical, we perform meticulous installations, ensuring your system is correctly sized for your home's layout and sealed properly. This prevents air leaks and strain on components, providing reliable comfort and efficiency from day one.

Thermostat malfunctions are common and often don't require a full system replacement. Our technicians will diagnose the issue, which could be faulty wiring, calibration problems, or a dead battery. We repair or replace the thermostat as needed, restoring accurate temperature control and potentially saving you from an unnecessary system replacement.

If you're experiencing inconsistent temperatures, strange noises, or a complete lack of heating/cooling even after checking the thermostat, it likely indicates a deeper system issue. Our repair services address problems like refrigerant leaks, faulty components, or ductwork issues—common culprits behind poor performance that a simple thermostat fix won't resolve.
