Michael Murphy Hvac: Certified HVAC Repair Serving Lilburn, GA 30047

First, check your thermostat settings and air filter, as a dirty filter is a common culprit. If that doesn't help, turn the system off to prevent further strain and call a professional. For Lilburn homeowners, immediate attention is key during our hot summers to avoid a complete breakdown. We offer prompt emergency service to diagnose issues like refrigerant leaks or compressor failure and get your cooling restored quickly.

Signs of a poor installation include uneven heating or cooling, strange noises, frequent repairs, and unusually high energy bills. In Lilburn homes, improper sizing for our climate is a common issue—a unit that's too large or too small won't run efficiently. Our team can perform a detailed evaluation of your system's performance and installation quality, ensuring it meets local codes and is optimized for your home's layout and our regional weather.

A proper installation starts with a Manual J load calculation to correctly size the unit for your home's square footage, insulation, and our local climate. We then ensure precise ductwork fitting, secure electrical connections, and thorough system testing. For Lilburn residents, this careful process is crucial for achieving reliable cooling during humid summers, efficient heating in winter, and lower long-term operating costs, preventing the common issues that stem from rushed or incorrect setups.
