## Resource

🔥 Got HVAC questions? We've got answers! This week, we're sitting down with Nathan Shafer, owner of Shafer Heating and Cooling in Hillsboro, Ohio — a trusted local expert who knows what it takes to keep your home comfortable year-round. From diagnosing that mysterious noise your furnace has been making all winter 🥶 to knowing when it's time to replace vs. repair your AC unit ☀️, Nathan breaks it all down in a way that actually makes sense. 🌡️ Ever wonder why your AC seems to run non-stop during a July heat wave — even when it's working perfectly? This episode dives into design temperatures and explains why, in many regions, a 90°F design temperature means your system may run continuously when summer heat peaks. Nathan also covers how sun exposure, shade, and everyday actions like opening doors can shift your indoor temps — and why even a correctly sized, properly functioning system can fall a degree or two behind when conditions push past the design threshold. Whether you're a homeowner trying to understand your system or you're dealing with an urgent issue and don't know who to call — this is the episode for you. 💡 Learn what separates a quality HVAC contractor from the rest, what questions to ask before hiring anyone, and how Shafer Heating and Cooling has built a reputation for honest, reliable service in Highland County and beyond. Don't get left in the heat — or the cold!
