Carrier HVAC ProductsAs a Carrier Factory Authorized Dealer, Mann-In offers a full range of services to determine and resolve problems with comfort and energy efficiency.  Our highly trained technicians perform state-of-the-art blower door testing to identify leakage and insufficiencies in the thermal envelope of your home.  The resolution of these issues will result in significant energy savings, healthier Indoor Air Quality, and improved comfort.

A blower door consists of a variable-speed fan and flexible panel that mounts into the frame of an exterior door.  A pressure gauge measures the pressure difference inside and outside of the house.  An airflow manometer and hoses measure airflow.  When the powerful fan draws air out of the house, the air pressure inside is lowered.  The higher outside air pressure then enters through unsealed cracks and gaps.  While this technology was introduced to the United States in the late 1970’s, the multifold benefits are just beginning to be appreciated.  Through blower door testing, the technicians from Mann-In protect your comfort, system efficiency, and health of your home environment.
