STEP-BY-STEP CLEANING METHOD

Air Quality Controller's Step-by-step Cleaning Method


Remove and vacuum each register.


Air whip in motion, the most aggressive system available.


Agitate with air whip in each supply and return register.


Clean the main trunk lines.

    • Connect negative air vacuum system to the main duct on supply side near furnace.  This creates suction throughout each register
    • Vacuum each register with a portable HEPA vacuum.
    • Scrape caked-on dirt from each branch line using an air whip attached to a 35 foot snake.  This is the most aggressive agitation device available.
    • After each branch has been cleaned,  the main trunk lines are cleaned to the negative air vacuum.
    • Repeat the following steps for the return side of the ventilation system.
    • (Optional) The entire ventilation system is sanitized with unscented EPA registered EnviroCon to retard future fungal growth

Additional Services Offered  (Optional)

   
1. Clean A/C Evaporator
    Coil $80
2. Clean outside A/C
    Condenser Coil $80

Before an air conditioning system is installed in a home, the size of the home must be matched with the size of the coils.  This will ensure that the proper BTU cooling requirements are met.  The condenser coil (located outside the home) and the evaporator coil (located in the duct work directly above the furnace) are designed to provide efficient heat transfer to cool a particular area.  Over time, the coil's capacity to cool efficiently is depreciated by airborne contaminates clogging the coil fins.  The result is inefficient heat transfer, a decrease in airflow, and a concern for indoor air quality.

Dirty coils increase the amperage and the amount of time needed for the system to reach the desired indoor climate.  HVAC systems with dirty coils can consume 35-40% more energy than a system with clean coils.

Consider a typical cooling season from May 15th to September 15th.  This is equal to about 1600 hours of operating over 125 days (12.8 hours per day).  A typical 4 ton residential cooling system would cost about $704 to operate for 1600 hours with clean coils.  When the coils get dirty, that same system would have an operating cost of $964.48.  This is a 37% increase on your utility bill.

3. Clean Furnace Blower - $120

The picture above shows the result of a blower fan that has been running with inadequate filtration. The efficiency of a dirt laden blower fan can be reduced by 50% or more.   With a blower fan that is only performing at 50%, the lack of airflow puts the heat exchanger at risk of overheating and cracking. Think of this in terms of an expensive furnace replacement caused by overheating.  Also, the cooling vent holes on the motor are covered with dust. This can lead to motor failure

4.  Clean Dryer Vent   - Call for Pricing.                                 

The clothes dryer vent is the cause for 14,000 fires in the United States each year.  It is recommended that the dryer vent is cleaned every 1 1/2 - 2 years. .
