Ductwork Repair, Sealing & Design in Milwaukee
Your furnace and A/C are only as good as the ducts that carry their air. We fix the leaks, bottlenecks, and bad layouts that make rooms uncomfortable.
Leaky or poorly designed ductwork can waste 20–30% of the air your system heats or cools — you pay to condition it, then it leaks into the basement or attic before reaching your rooms. If some rooms in your home are always too hot or too cold, the ducts are usually the culprit. E & R Heating and Cooling designs, repairs, and seals duct systems across Milwaukee County.

Signs Your Ducts Need Work
Rooms that never match the thermostat, weak airflow from certain vents, whistling sounds, excessive dust, or a system that runs constantly without keeping up — all point to duct problems. Milwaukee's older homes are especially prone: decades of renovations often leave behind crushed runs, disconnected joints, and undersized returns.
Comfort in Every Room
Whether you're finishing a basement in Greenfield, adding a second story in Wauwatosa, or just tired of a freezing back bedroom, we'll measure your system's actual airflow and fix the real problem — not just crank the blower. Duct sealing alone often pays for itself in one or two heating seasons.
Frequently Asked Questions
How do I know if my ducts are leaking?
Common signs include uneven room temperatures, dusty rooms, high energy bills, and visible gaps at duct joints. We can test your system and show you exactly where air is escaping.
Can you add ductwork to a finished basement or addition?
Yes — we design and install duct runs for remodels and additions, sized so the new space gets proper airflow without starving the rest of the house.
Is duct sealing worth the cost?
Usually, yes. With 20–30% of conditioned air lost in typical leaky systems, sealing often pays back within one to two seasons — and comfort improves immediately.
