HVAC Financing From GE. 

Kelly Heating now provides a financing program to provide you with the convenience and the ability to purchase the equipment you need.

This new system is a calibrated air flow measurement system used to test and document the airtightness of forced air duct systems in both houses and light commercial buildings.  The Duct Blaster fan is directly connected to the duct system, typically at a central return, or at the air   handler cabinet; With the remaining registers and grills temporarily taped off, duct airtightness is measured by either pressurizing or depressurizing the duct system and precisely measuring the fan flow and duct pressure.

 Duct airtightness measurements are used to  diagnose and demonstrate leakage problems, estimate efficiency losses from duct leakage, and certify the quality of duct system              installation.

The Duct Blaster fan can be mounted directly to the HVAC system. 

The duct blaster can be used to measure the total amount of air moving through the air handler.
