HVAC ducts are made of lightweight metal sheets, so they are susceptible to holes. Holes in your ductwork can result in leaks and prevent the air conditioner system from working optimally. Finding and fixing holes in your duct may be challenging, but searching for HVAC repair near me will help you solve the issue permanently.
Some signs that your ductwork has holes include:
- Rise in your energy bills
- Inefficiency of your HVAC system
- Evidence of peeling, sealant, or metal chips in your vents
- Dust or debris in your home that will not go away
- Inconsistent temperatures throughout different rooms in the same house
Here are some tips on repairing holes in your HVAC ducts:
Gather the Items You Need
Fixing holes in HVAC ducts requires that you have the right tools. You need to gather tools and supplies to patch the hole permanently. Some items you may need include
- Safety glasses
- Construction-grade gloves
- Tape (metal foil)
- Tape squeegee
- Self-tapping screws
- Silicon caulk
- Caulk gun
- Utility knife
- Metal sheet
- Tape measure
- Drill motor
The tools and supplies make fixing ductwork holes easier. They can keep you safe from harm when repairing your HVAC ducts.
Inspect Your Ducts
Handling your ductwork can prove stressful as you might not know where the issue lies. Start by inspecting your ductwork and vents to check for holes. A comprehensive inspection allows you to understand the extent of the problem and devise ways to fix them.
Visually inspect ducts you can access: Climb into the attic, basement, and crawlspace and check for holes. You can turn your HVAC system on and repeat the process; any air coming through the duct means there is a leak you must fix. During your inspection, mark all areas of interest to avoid forgetting about them when fixing.
Inspect HVAC registers and vents to see if any connections are loose. Loose registers and vents might be losing air, so you need to tighten them to improve your HVAC’s efficiency.
Clean the Surfaces
Taping small leaks might not work since the adhesive’s ability might be hindered by dust and grime buildup in your ducts. You should clean the surfaces before applying tape or patches to fix the holes.
Damp your rag in water with dishwashing liquid and use it to wipe down the surfaces. Using another rag, you can dry the surface to make sure the sealing tape bonds correctly.
Fix Holes in Your Ductwork
After identifying leak spots and cleaning the surfaces, you can now fix the holes. There are two common ways of fixing duct holes depending on the extent of the problem:
Using HVAC Tapes
HVAC tape is specially designed to seal leaks on HVAC systems. They are ideal for fixing small leaks where the air pressure is not too high. Experts often prefer HVAC tapes since they are wide enough to bridge more significant gaps and can be cut to size. They bond well with the duct’s metal surface and have the right thickness to withstand elements and pests.
While HVAC tapes are strong and stick well, they can start to dry out and fall away after some time. You need to check on it often or use sealant for longer-lasting results.
Using Duct Sealant
Duct sealant is a type of putty used to seal larger holes in your ductwork. Using a caulking gun, you can apply this thick, pasty, and paint-like substance to gaps and cracks, then spread using a paintbrush. Water-based duct sealant bonds well and is easy to clean.
Insulate the Ducts
Once all the leaks in your ductwork are sealed up, you should insulate them to prevent the leaks from reoccurring. Applying insulation around your ductwork will prevent pests from making holes. This will protect the sealant patches, allowing them to hold off more air pressure. Insulation prevents further air leaks, so your system works more efficiently, which can save you money.
The best insulation options to use around your ducts are fiberglass or foam. Look for insulation material with a high R-value for the best results.
