Cregger Company - North Charleston's Certified HVAC Repair

We are an authorized dealer and installer for Goodman and Daikin systems, so we have in-depth expertise with these specific brands. This allows us to provide knowledgeable installation, precise maintenance, and efficient repairs. However, our licensed technicians are trained to service and repair a wide variety of HVAC makes and models to meet the needs of all our North Charleston customers.

Many homes in our area have aging systems that become less efficient and more prone to breakdowns, especially during our humid summers. We can perform a thorough evaluation of your current system, discuss repair versus replacement options, and help you choose a solution that fits your budget and comfort goals. For older systems, we often recommend considering a modern, energy-efficient replacement, which can significantly improve comfort and reduce monthly energy costs.

Yes, thermostat issues are a frequent call we get from North Charleston residents. The local humidity and temperature fluctuations can sometimes cause wiring problems or calibration drift in older thermostats. Our technicians can diagnose whether your thermostat needs recalibration, repair, or an upgrade to a newer, more reliable model—including programmable or smart thermostats that can help you manage your home's climate and energy use more effectively.
