Uneven rooms don’t always mean you need a new furnace or AC. In many Utah County homes, duct leakage is the hidden culprit stealing airflow before it reaches the rooms that need it. Below are three quick case studies showing how our test-and-seal approach (with Aeroseal duct sealing) solved hot/cold rooms without equipment replacement.
TL;DR: We test first, seal leaks from the inside, verify results with a post-test, and balance airflow. Most homes see a dramatic drop in leakage and a noticeable comfort lift. See what happens on install day and how to read your duct leakage report.
Symptoms that point to duct leakage (not a bad furnace)
- One or two rooms run noticeably hotter/colder than the rest
- Long run times but weak airflow at distant registers
- Dusty returns/closets; comfort issues after a remodel or basement finish
- Attic or crawlspace ductwork in older Lehi/AF/PG homes
Case Study #1 — Lehi two-story with attic ducts (1998 build)
Complaint: Hot upstairs bedrooms, weak airflow at the far end of the hallway.
Findings: Pre-test measured high total leakage at 25 Pa; multiple unsealed takeoffs and boot connections in the attic.
Work: Aeroseal duct sealing + minor boot resets; follow-up balancing at registers.
Result: Post-test verified a large leakage reduction and improved delivered airflow to both end bedrooms. Thermostat setpoint now holds without overrun.
Case Study #2 — Orem rambler, finished basement add-on
Complaint: Family room cold spots after basement finish; main level “never quite warm.”
Findings: Flex connections and a long return run added during the remodel; measurable leakage to interstitial spaces.
Work: System cleaning (air duct cleaning) first, then Aeroseal; we also corrected a crushed transition.
Result: Quicker warm-up and even temperatures between main level and basement. Dusty return closet issue resolved.
Case Study #3 — Provo townhome, long branch runs
Complaint: End bedroom barely gets airflow in summer.
Findings: Several tiny leaks at tees and boots were starving the longest branch; damper positions were out of balance.
Work: Aeroseal to tighten the network, then manual damper adjustments and register tuning.
Result: Noticeably stronger airflow at the end bedroom and balanced temps across the top floor.
Our test-and-seal method
- Measure: We run a pre-seal duct test at 25 Pascals to establish baseline leakage (see Duct Blaster® 101).
- Clean if needed: If the system is dusty (post-remodel, pets, etc.), we perform air duct cleaning first so sealing locks in a clean system.
- Seal from the inside: Aeroseal targets leak edges—no tearing into walls/ceilings.
- Verify: We repeat the test after sealing and provide a before/after report.
- Balance: Final damper/register tuning to deliver air where you feel it.
When Aeroseal isn’t the right fix
- Crushed or disconnected ducts that require repair/replacement first
- Serious design issues (undersized/oversized trunks, missing returns) that need redesign
- Equipment performance problems (e.g., failing blower) — we’ll flag these during inspection
FAQ
Will I need a bigger system after sealing?
Usually not. Tightening the duct network helps the existing system deliver air more effectively.
Do you cut drywall?
No. Aeroseal works from inside the ducts. If we discover a disconnected run, we’ll propose the cleanest access option.
How long does the visit take?
Most single-system homes are completed in 4–8 hours including testing and reporting; larger homes can take longer.
Not sure if it’s leakage or design? We’ll test and show you the data.
