Step 2: Important Things You Should Consider

You want to clean the air inside your home, there is more than just air duct cleaning to consider

Step 3

What you should consider when hiring a duct cleaner

Some duct-cleaning companies clean heating and cooling equipment (condenser coils, fan blades, etc.) as part of a comprehensive duct cleaning, and some charge less if you skip this step. Your heating and the air-conditioning contractor may do this for you, but don’t assume these services are part of regular maintenance; be sure to ask explicitly.

Steps You Can Take.

Inspect the condition of the air filter. The dirt that ends up on your filter has passed through your return air duct system. Clogged air filters is signs that your air ducts might be in need of cleaning soon.

Find out when your furnace blower fan and the evaporator coil was last cleaned. When the blower wheel and AC coils become dirty, it forces dust into the supply side of the air duct system. The dust will continue to gather inside the main plenum and supply branches until cleaned. Dirty blower and coils affect the air ducts.

Locate documents on when the air ducts were last cleaned. You could always open one return vent on the main floor and do your own inspection with a flashlight and mirror. If you’re not comfortable with it, then locate a local certified air duct cleaning specialist and ask for a free visual air duct inspection.

Complete System Cleaning

To the following pieces of information should be consider with every air duct cleaning.

Furnace Air Filter

Frequently changing air filters is the best way to keep dust, allergens, and other particles out of your home. Once you get the air ducts cleaned in your home it’s highly suggested to replace or upgrade the air filter to maximize the air quality in your home. 

Blower Fan Blades

In the CMHC duct-cleaning study, researchers found that when duct cleaners also cleaned the blower fan blades, there was a small reduction in airborne particles. Cleaning the blower fan might also slightly improve your system’s energy efficiency.

Evaporator Coils

Evaporator coils cause condensation, dehumidifying the air before it circulates through your home. Condensed moisture can cause dust and other particles to stick to and build up on the coils. Also, cleaning the collector pan beneath the coils.
