Attachment used for our extensive type duct cleaning
Standard Duct Cleaning: In performing our standard duct cleaning, we create a suction on the duct system at the furnace location. We cover all of the vents in the home with a sheet of newspaper. This creates what is known as a negative pressure within the duct system.
When we remove a sheet of newspaper from one of the vents, all of our suction will be on that one vent as the other vents are all blocked off. We then blow compressed air (200 psi) into each vent one at a time.
When we are through blowing high pressure air through all the vents, we bring our compressed air back to the furnace location and clean all the dust that is in the plenums and air filter compartment. We also clean the blower and all the blower fan blades.
Extensive Duct Cleaning: Our extensive duct cleaning is similar to our standard duct cleaning. The major difference is with an attachment used for cleaning during the blowing of air into the vent. This attachment has a series of flexible rods that are added to the nozzle of our compressed air and are run through the ducts. At the end of the flexible rods are eight skinny tentacles that are about eight inches long that frantically whip around scrubbing, agitating and blowing the dust and debris along with the suction.
This method of duct cleaning is more thorough than our standard duct cleaning and quite a bit more time consuming.
Furnace and Boiler Cleaning: Much of our work comes from referrals by HVAC technicians that service and repair oil furnaces. After a period of time, an oil furnace will build up with soot inside the heat exchanger (the exhaust flues inside the furnace), the base of the chimney, and the exhaust pipe. This build-up will drastically reduce the efficiency of your furnace. If it goes unchecked it will eventually start plugging up. The exhaust will have a hard time venting properly and will back up into the home.
An oil fired, forced air furnace, should be power vacuumed every 3-5 years as a regular part of your maintenance. Most boiler systems (hot water heat) should be cleaned every 1-2 years.
Remember, a clean furnace is an efficient furnace and will save you money in oil consumption. The soot that builds up in your furnace will eventually disintegrate the metal inside the furnace heat exchanger, in which case the furnace will need to be replaced.
