Duct Sealing in Elkton, MD
If certain rooms never feel like the thermostat setting—or your system seems to run longer than it should—leaky ductwork may be a major reason. Duct sealing is designed to close hidden gaps and disconnections so heated or cooled air actually reaches the rooms you’re paying to condition.
Moon Air offers AeroSeal duct sealing as a targeted solution for duct leakage, especially when comfort is uneven or airflow is inconsistent.

What duct sealing is and why it matters
Your duct system is the delivery network for your HVAC equipment. When ducts leak, conditioned air can escape into unconditioned spaces (attics, crawlspaces, wall cavities), which reduces delivery to living spaces and forces the system to work harder.
Professional air duct sealing can help improve:
- Comfort balance (reducing hot and cold rooms)
- Airflow to registers (better delivery where it’s needed)
- System performance (less wasted run time)

Got Questions? We've Got Answers!
How do I know if I need AeroSeal duct sealing?
If you have uneven temperatures, weak airflow in certain rooms, or comfort that doesn’t match system run time, duct leakage may be contributing. We can evaluate your symptoms and recommend whether sealing is the right next step.
Is AeroSeal safe for homes?
AeroSeal describes its duct sealing as a non-toxic aerosol sealant process designed to target leaks without coating the entire duct interior.
Will duct sealing guarantee a specific temperature improvement?
No—homes vary. Moon Air notes performance-related benefits from AeroSeal duct sealing in its published guidance, but results depend on duct condition and home/system variables.
Can duct sealing be done without replacing my HVAC system?
Yes. Duct sealing is often completed as a standalone comfort upgrade when equipment is still serviceable.
What areas do you serve?
Signs you may have leaky ducts
Duct leakage doesn’t always announce itself, but it often shows up as comfort and performance frustration. Duct sealing is commonly considered when homeowners notice:
Uneven temperatures from room to room
If one room is consistently hotter or colder than the rest of the home, duct leaks (or duct design issues) may be preventing proper delivery.
Weak airflow at certain registers
When airflow feels noticeably lower in parts of the home, sealing can help if leakage is a contributor. If the issue is balancing or equipment-related, we’ll recommend the correct next step.
Higher run time with limited comfort payoff
When your system runs longer but comfort doesn’t improve proportionally, duct leakage may be part of the reason the system can’t “keep up.”
