This summer, Winthrop homeowners are seeing higher-than-usual energy bills due to hidden chimney inefficiencies. A clean, inspected chimney isn’t just about safety—it’s about keeping your AC from working overtime. We’re seeing a surge in calls from locals who noticed drafts or soot stains after Memorial Day and realized their chimney was sabotaging their comfort.
Most Winthrop homeowners ignore this one summer efficiency killer
You’d be surprised how many Winthrop homes have a chimney acting like an open window. A clogged flue or cracked liner lets cool air escape while pulling hot attic air downward—exactly what you don’t need when the humidity hits from Winthrop Harbor. We’ve inspected chimneys on Ocean Avenue and Shirley Street this month alone where homeowners thought their AC was struggling, only to find a soot-choked flue. A proper chimney sweep clears the blockage and seals gaps, cutting unnecessary cooling costs. Don’t wait for your next bill to spike—schedule a free estimate before July.
What your chimney’s summer efficiency really costs you (and how to fix it)
Here’s the math Winthrop locals miss: a dirty chimney can reduce your home’s cooling efficiency by up to 30% by forcing your AC to run longer. We’ve seen it on Central Avenue and Shirley Street—homeowners paying $500+ extra over the summer because their chimney wasn’t pulling air properly. The fix? A chimney inspection to check for cracks, a sweep to remove creosote buildup, and a chimney cap if yours is missing. Pro tip: If you’ve got a masonry fireplace, a relining might be the summer upgrade your wallet needs. Book a Winthrop-specific sweep before the July heatwave hits.
