Blower Door Testing in Covington, GA & Surrounding Areas

At Redwood Heating & Air, we provide professional blower door testing in Covington, GA and nearby communities to help homeowners and builders achieve optimal energy efficiency, comfort, and code compliance. Whether you're looking to improve your existing home’s performance or meet energy standards for a new construction project, blower door testing is a crucial step in understanding how airtight your building really is.

What Is Blower Door Testing?

Blower door testing is a diagnostic tool used to measure the airtightness of a building’s envelope. Using a specialized fan mounted in an exterior doorway, we depressurize the home and monitor how much air leaks through cracks, gaps, and other unintended openings. The results give a clear picture of how well your building’s shell—its walls, windows, doors, roof, and foundation—separates indoor air from outdoor conditions.

This test is especially important in energy-efficient construction, where minimizing air leakage is key to maintaining indoor temperature, reducing energy bills, and improving indoor air quality.

Why Airtightness Matters

The building envelope is your home’s first defense against energy loss, moisture intrusion, and outside contaminants. If the envelope is leaky or poorly sealed, you could experience:

• Increased heating and cooling costs
• Drafts and hot/cold spots
• Excess humidity or condensation
• Mold growth and structural issues
• Poor indoor air quality

Blower door testing identifies these problem areas, helping you take corrective action before they lead to long-term damage or higher utility costs.

Benefits of Blower Door Testing

Whether you’re a homeowner or a builder, blower door testing offers several benefits:

• ✅ Improved Energy Efficiency – Reduce wasted energy and lower utility bills
• ✅ Enhanced Comfort – Eliminate drafts and maintain consistent indoor temperatures
