How to Prepare for Air Duct Cleaning

In an effort to make your air duct cleaning goes as smooth as possible, here are some guidelines and helpful tips that can help you prepare for our team! Please remember, most homes (with 1 furnace) take approximately 3 to 5 hours to complete the air duct cleaning. Homes with more than 1 furnace take longer.

  • Who is Home? Upon our arrival, we will confirm the work we are there to perform and will request authorization, in writing, to proceed. In the event that you are not able to meet us at your home; whoever is occupying the home must be over the age of 18, or we will not proceed into the home.
  • Pets. Pets are perfectly ok to have around as most of our team are animal lovers! However, our technicians will be in and out of the home, or fenced in yard, at various times throughout the visit. Most air duct cleanings take 3 to 5 hours to complete for a 1 system home. If you are worried your pet will escape, please have them in a secure area that they won’t be able to escape. A door to the home will be open for those 3 to 5 hours. Our technicians are very conscious about making sure pets don’t escape, but we always expect the unexpected. If your pet is not good with outsiders being in the home, we ask that you please put them in a secure area where they won’t be frightened and our team won’t be put at risk.
  • Clearances. The technician will go right to work upon arrival. It is crucial that they have a clear path too and from the furnace. Please make sure that there is nothing blocking the furnace or setting on the furnace. Imagine having a 4ft bubble around the furnace and ductwork where the technician will be working. Please make sure there is a clear path from the entry to the home, to the furnace/indoor unit; whether it be in the basement or upstairs. If the furnace/indoor unit is in an attic where the entrance is in a closet; please make sure clothes are removed as sometimes insulation will fall when we are getting in and out of the attic. Please make sure there is a 2ft bubble of clearance around each register. If there is a heavy object covering the register, please have it out of the way when we arrive. If you know of any low hanging wires, powerlines, cables; etc. please let the technician know as soon as possible.
  • Driveway. The technician may ask to park in the driveway as it provides the closest access to the furnace. The less vacuum hose we use, the better the vacuum. If someone in the home has a vehicle in the garage that will need to be moved at some point during the visit, the technician will typically ask to swap you places (no he/she will not park in your garage) so that you can come and go freely throughout the visit.


  • Who Will Be Coming to My Home? One service technician will generally arrive at your allotted time you were given from our office team. They will go over the air duct cleaning visit with you and confirm the services they are there to provide. They will ask you to help them locate the furnace.
  • How Do They Protect My Home? Our technicians will wear shoe covers, as well as lay canvas runners/corner guards to protect floors and walls.
  • How Long Does the Air Duct Cleaning Take? Most homes (with 1 furnace) take approximately 3 to 5 hours to complete the air duct cleaning. Homes with more than 1 furnace take longer. Your technician will typically keep in contact with you to explain how long he/she may be in the home.
  • How Long Without Heating or Air Conditioning? Depending on the time of year, you will be without heating or air conditioning for the duration of the air duct cleaning. Once the heating or air conditioning is turned back on; you can expect a recovery period of approximately 1 degree per hour. For example, in summer; you will be without air conditioning for approximately 4 hours. When they turn the system on for the first time (at the end of the visit) the thermostat may say 76 degrees, but you normally have it set for 72 degrees. Please know that it could take approximately 4+ hours to recover and get back to set temperature. Your system will be doing all it can on extremely hot days, so please be patient. As far as heating goes; with natural gas or propane furnace, you may have a quicker recovery time than with an electric furnace/heat pump, so again, please be patient.
  • What’s that Smell? Most of the time, especially with a new natural gas or propane furnace, you will smell a slight odor when the system turns on for the first time that season or after the air duct cleaning. This is very normal. Even with the best filtration system, some dust can accumulate on the heating elements during the off season.
  • Will My Door be Open? In most cases, yes. If your furnace is located inside your home, then we will have to have either a door or window open so we can run the vacuum hose back to our Duct Truck located outside. Our trucks are equipped with various tools and equipment to help block some of the air coming into the home, but we cannot fully seal it off during the air duct cleaning process.
  • Will You Have to Cut Into My Ductwork? Yes. In order to properly clean your ductwork, we do have to make access openings to connect our vacuum hose. We also have to make small openings to allow our tools to go thru the ductwork to properly clean them. These openings are sealed up upon completion and can be used for future air duct cleaning services or duct inspection.
