Answers: How do I anchor an outdoor AC unit to a concrete pad?

• Outdoor AC unit installation
• Concrete anchoring techniques
• Using Tapcon concrete anchors
• Hammer drill vs rotary hammer drill
• Clearing concrete dust from anchor holes

What it concludes

• Tapcon concrete anchors are preferred by 71 percent of the community for concrete anchoring.
• The drill bit size on Tapcon packaging matches the required drill bit size for 3/8 inch anchors, unlike smaller sizes.
• A rotary hammer drill drills much faster and easier than a standard hammer drill.
• Applying too much continuous pressure can make too much heat and promote drill bit breakdown.
• The most common failure point is debris and concrete dust bottoming out the hole preventing the anchor from driving further.
• For stripped holes, try a half-inch Tapcon or wedge/strike anchors to secure the unit.
