Why is My House So Dirty? - Nashua, NH, Brookline, NH & Wilton, NH | Sanford Temperature Control, Inc.

Have you ever looked around your house and thought, “Where is all this dirt and dust coming from?”

Many homeowners don’t realize that dirt, dust, allergens, and even viruses can get circulated into their indoor breathing air when furnace and air conditioning systems are running. How can that be, even when homeowners change their air filters regularly AND have yearly maintenance on their home comfort systems?

Have you ever looked into the vents/registers for your air system? If not, then consider taking a look, and grab a flashlight if you’re really daring; remember to shut the system down while you’re looking so you don’t get a face full of dust and other debris! Is it as bad as you thought? Be sure to check several different ones to identify any problem areas.



The image on the left was taken by one of our highly-trained technicians before a duct cleaning. The image on the right is the same section of duct work after it had been cleaned and sanitized. Quite a difference!

Whenever your system runs, dust, dirt, and germs are sent into your home. It’s been a bad winter for colds and flus, and this is a perfect way for it to spread through your family. The worst times of year for poor indoor air quality tend to be summer and winter, when homes are buttoned up tight to conserve conditioned air.

If what you saw looks like something in the “before” image above, then it’s time to get those nasty ducts cleaned out.


How We Clean Your Ductwork

Get Clean! – We clean register covers to remove cooking oil film, nicotine film, and other dust-collecting substances.

Breathe Deep! – We deep-clean the source of the air supply including supply and return ductwork leading up to the registers, as well as the main supply and return trunk.

Scrub – Air ducts are brush-vacuumed clean with our exclusive, patented ROTOBRUSH™.

Goodbye Contaminants – The ROTOBRUSH™ removes pollutants that circulate through the air duct system.

Sanitize! – We will sanitize your air ducts and vents with an environmentally safe sanitizer commonly used in hospitals and nursing homes, leaving behind a fresh scent.


Once this duct cleaning process is complete, you’re on your way to a healthier, more comfortable home!

In order to remain clean, however, you may be interested in asking about our air purifiers or germicidal UV lights. These products will help kill the bacteria and germs that may get introduced into your indoor breathing air on a regular basis.
