Furnace and Duct Cleaning – Gas and Oil

Johnson Chimney and Johnson Power Vac, Inc. removes all dirt and debris with our industrial high-power vacuum removal system. We also brush out the heat exchanger chamber, brush, clean, and inspect burners. Each cleaning includes a complete inspection and detection of carbon monoxide leaks.

Recommended Cleaning Schedule: Every two to four years

Starting with the room farthest from the furnace, we blow 150 pounds of pressure down toward the furnace, where simultaneously our high-powered industrial power vacuum system removes all debris. The procedure is a combination of forced air and suction. Included is the return, supply, and blower motor.

Our sanitizing process is registered by the EPA, as a complete bacteriostat, fungistat, germistat, and all-purpose deodorizer. Applied after our basic cleaning to control odors associated with bacteria, mold, mildew, animal, and smoke odor, the process kills 90% of the micro-organisms that live in your air-duct systems.

Johnson Chimney Service’s Procedure for Duct Cleaning

  • We start with a tour of the property with the client to locate where vents, main ducts and furnace are.
    In this step we try to uncover any special concerns or needs.

  • Then we connect our HEPA Air Care Negative Air Machine to an access opening in the main duct line. This is where all the dust and debris will be collected.

  • After that we start cleaning the vents from the top of the house.

  • All supply vents will be air washed with 180 PSI of a truck mounted compressed air to push the dirt and debris towards the main duct.

  • All returns vents will be removed and whipped with the octopus to dislodge caked on debris and air sweep towards the main line.

  • We will show you the video camera images of before and after cleaning.

  • Then all main lines will be cleaned through access openings.

  • The filter will be checked and replaced (when clients provide filter).

  • Service opening doors will be installed in compliance with Standard 05 of NADCA.

  • Sanitizer treatment will be applied to kill all dust mites, bacteria, mildew and odors.

  • Once a customer approves and signs, the job will be finished.
