Blower Door Testing in Greenville–Spartanburg

Is Your Home Leaking Air (and Money)?

Air leaks around windows, doors, walls, and ceilings make your HVAC system work harder and your energy bills go higher. Blower door testing—also called home air tightness testing—is the most reliable way to detect and measure these leaks.

Whether you’re building a new home or upgrading an existing one, Collins Mechanical provides accurate, code-compliant blower door testing throughout the Greenville–Spartanburg area.

What Is Blower Door Testing?

Blower door testing involves mounting a calibrated fan to your home’s front door to pull air out of the house and lower the interior pressure. This allows us to measure how much air leaks into the structure from outside.

It’s required by code for many new constructions and is a key part of understanding your home’s energy efficiency.
