Follow these tips to better prepare your home for duct cleaning:

Clear Zones Around All Openings Of Ducts

Before arriving at your house, try to contact the technicians to ask how much room they need around each vent and register. Instead of clearing the work areas, this will allow them to spend more time cleaning the ducts. Then for easy access, remove any furnishings or artifacts from those areas.

Cover Furniture

While technicians will try to keep dirt and dust within the duct system by applying pressure, some residual particles can get into your living room during the cleaning process. As such, before the cleaning starts, you can cover up your furniture and other belongings. To keep your home tidy, some contractors provide coverings and drop cloths, while others do not.

Preparing For A Duct Cleaning Meeting

Cleaning your home air ducts becomes necessary when you pay more attention to your home air quality and take care of indoor air pollution. Good preparation for this makes the job more manageable and saves everyone’s time. 

Protect your pets and children during our visit

The duct cleaning procedure can upset your children, especially those with sensitive ears. So you can arrange a call from our technicians when the children are not at home. If you can’t achieve this, spend time with our technician before you start discussing safety procedures to make sure your children stay safe.

Also, let technicians know if you have your pet nearby. Keep your pet safe in rooms where technicians would not work to reduce noise, preventing fright.

Facts of Interest!!!

Do you know the following?

  • The very first construction of a steam heating system was in England. This helped the Governor to grow grapes in the cool temperatures at that time.
  • “Cool Man”: This one for fun only. Though not specifically related to HVAC, in the late 1940s, the use of the word “cool” (as in “that’s cool!” or he’s cool”) began when jazz musicians used it to describe their music as a word of approval; that jazz was “cool.” It was further spread to regular use in the early 50s (to be ’hip’).
