HVAC Duct Replacement in Birmingham, AL
When your ductwork leaks, the air you pay to heat and cool slips into your attic or crawlspace before it ever reaches you. The result is uneven room temperatures, dustier air, and energy bills that climb without explanation. Hemphill Services has helped families in the Birmingham area with HVAC duct repair since 1954.
Our technicians track down loose joints, cracks, and crushed sections, then seal and secure them so conditioned air flows where it should. Whether you’re in Homewood, Hoover, or Mountain Brook, we’ll inspect your full duct layout and explain what needs attention before any work begins.

Signs It’s Time to Replace Your Ductwork
How to tell when repairs have run their course.Ducts don’t last forever. Once the lining degrades or damage spreads through the network, sealing one leak just shifts the problem down the line. These signs point to a system that needs replacing, not another patch.

What a Full Ductwork Replacement Involves
A clean, engineered process from removal to final airflow.A new duct system begins with careful design. Our team measures each room and sizes every duct so air stays balanced throughout. Right-sized, sealed lines also recover the 20% to 30% of conditioned air that leaky systems lose to the attic.
Next comes removal. We carefully take out the old ductwork, bag it, and haul it away, keeping your attic and living spaces clean throughout. Depending on your home’s layout, we install insulated flexible duct or rigid metal trunk lines.
New ductwork also helps the rest of your home’s air quality work better. When the lines are sealed, your system carries clean, filtered air instead of pulling dust and attic debris into the rooms you live in. That cleaner baseline lets equipment like an air purifier or a whole-home dehumidifier do its job instead of fighting a leaky system.

HVAC Duct Replacement FAQs for Birmingham Homeowners
Common questions we hear from homeowners weighing a full duct system upgrade.
Most residential ductwork lasts 10 to 15 years before it needs replacing. Flexible duct liners break down, and seals dry out over time, which lets conditioned air escape. If your system is in that range and rooms feel uneven, replacement is worth considering.
Newer ducts in good shape can often be sealed instead. A ductwork evaluation tells you which path fits your home and budget.
A new high-efficiency AC or heat pump can underperform when it’s connected to old, leaky, or undersized ducts. The equipment is only as good as the lines that carry its air. Old ductwork can cancel out the efficiency gains you paid for and shorten the equipment’s life. When you replace a system, it’s the right moment to evaluate the ducts too. We check both so the whole system works together.
Yes. New, properly sized ductwork runs much quieter than old systems that whistle, rattle, or bang when the air kicks on. Those noises usually trace back to undersized ducts, loose connections, or metal flexing under pressure. A system sized for your home moves air at the right speed, which cuts the noise at its source.
Most whole-house duct replacements take one to three days, depending on the size of your home and attic access. A single-story house with an open crawl space moves faster than a multi-level home with tight runs.
Our team gives you a clear timeline after the in-home evaluation. We work to keep your living areas clean and minimize the time your system is offline. Larger Birmingham homes may run toward the longer end.
In most cases, you can stay home during a duct replacement, though parts of the day may be noisy. The crew works mainly in the attic, crawl space, or basement, away from living areas. Your heating and cooling will be off while the old ducts come out and new ones go in. For larger jobs, some homeowners choose to step out during the dustiest hours. We’ll walk you through what to expect before work begins.
If your home has older ductwork or rooms that never seem to match the temperature of the others, an upgrade may be overdue. Schedule a comprehensive ductwork evaluation with our Birmingham team and get a clear, practical plan for a quieter, cleaner, more efficient system.
