Frequently Asked Questions

• How long does a duct replacement take? A full system replacement in an average Darnestown, MD home typically takes 1 to 2 days. We work efficiently to minimize the time you are without AC/Heat.
• Can you add a new vent to a room? Yes. If you have a room renovation or an addition, we can cut into the main plenum and run a new duct line to supply air to that space.
• Is metal ductwork better than flex? Metal is more durable for main trunk lines, but modern flex duct is excellent for branch lines if installed correctly (pulled tight with no kinks). We use a hybrid approach for the best results.
• Do you insulate the ducts? Yes. All new ductwork we install comes with a thick jacket of fiberglass insulation (usually R-6 or R-8) to keep the air hot or cold until it reaches your room.
• Can you fix a noisy return vent? Often, noise is caused by undersized ducts moving too much air (high static pressure). We can enlarge the return duct or add a second return to quiet the system down.
