When Do You Need New Ductwork?
Four Common Reasons
You need new ductwork when the old ducts are worn out, the system was badly designed, you're adding space, or you're installing a new HVAC system that the old ducts can't support.
| Reason | Signs |
|---|---|
| Worn out | 20 to 25+ years old, brittle, rusted or torn |
| Poor design | Rooms that never cool, noisy vents, too few returns |
| Added space | Addition, bonus room or garage conversion |
| New HVAC system | Old ducts too small for the new equipment |
| Moisture damage | Moldy or sweating crawl space ducts |
Can You Replace Only Part of My Ductwork?
Yes. If only a few runs or one trunk are failing, we replace those and seal the rest. That usually costs $1,400-$3,000+.
- Good when most ducts are sound.
- Fixes hot rooms on one side of the house.
- Full replacement makes more sense if many runs are failing.

How We Design a New Duct System
Sized Room by Room
A new duct system from Right Away Heating and Air starts with a room-by-room design, so every space gets the airflow it needs and the system runs quietly.
- Measure each room and calculate its heating and cooling load.
- Size supply runs so each room gets the right airflow.
- Add enough returns so air flows back quietly.
- Plan the trunk layout for short, straight runs.
- Pick insulation rated for attic or crawl space conditions.
- Install, seal and test airflow at the vents.
Why Do Returns Matter So Much?
Returns matter because air has to get back to the system. Too few returns make the system noisy, starve it of air and leave closed rooms hot.
| Return Problem | What You Notice |
|---|---|
| One central return for the whole house | Hot bedrooms with doors closed |
| Undersized return | Whistling grille, noisy system |
| Leaky return | Dust, humidity, musty smells |

Should I Replace Ducts With a New AC?
You should replace ducts with a new AC when the ducts are old, leaky or too small. Putting new equipment on bad ducts wastes much of what you paid for.
- We inspect ducts on every system replacement.
- Doing both at once saves labor.
- New equipment needs the right airflow to hit its efficiency.

|---|---|---|
| Attic | Heat gain, crushed flex | Proper insulation, straps, short runs |
