Keeping Gwinnett County Comfortable
We started Thunder AC and Heating because we got tired of seeing our neighbors get burned by contractors who didn’t show up or didn’t know what they were doing. For a quarter-century, we’ve been the team that arrives when we say we will, diagnoses the problem honestly, and fixes it right without the runaround.
Whether it’s your home’s AC unit giving up in July or your business needing a complete HVAC overhaul, we treat every job like it’s our own family depending on us. Our trucks are stocked, our technicians are trained, and our phones are answered by real people who actually care about getting you comfortable again. That’s not just business for us – it’s how we sleep at night knowing we did right by our community.
To be the HVAC company Gwinnett County calls first because they know we’ll get it done right.
