Keystone Air Duct Cleaning in Abington uses a high-performance power vacuum in order to create a negative pressure throughout your air duct system. We insure the maximum negative pressure of our vacuum for all our cleanings via custom building "SOLID & SECURE SEALS" in your "PLENUM" over your coil for each home. We then remove all floor and wall registers and "SEAL THEM WITH MASKING TAPE". This way when we turn our vacuum on and open each register one by one the full force of our vacuum is isolated through whichever vein of the network we have open and are cleaning at that time. Once our plenum and registers are both properly sealed, we are ready to "ATTACH OUR VACUUM" and beging our cleaning.
Keystone cleanings start with opening each vent individually and insert rotating brushes as deep down into the duct as possible in combination with a booster which thrusts 265 mph gusts of wind down into the ducts. The trifecta of the vacuum pulling down, the brush shaking and scraping the walls of the ducts, and the booster pushing immediately flushes all lighter debris out of the house and into the vacuum. The remaining heavier debris is then pulled from the trunks using high powered electric air retraction tools through access holes made once every 15' to 25'. Remember that if your home is going to be Keystone clean then all access holes in exposed duct work must always be large enough to see first hand into the duct. That way the Keystone cleaner and the customer both "know for sure" that their ducts have in fact been cleaned out to their satisfaction. After, we pull out all of the remaining heavier material including all concrete, nails, insects, hair, dander, dirt, and dust debris we then repeat the process on the main return tunk line followed by the cleaning of the air handler itself. The air handler cleanings include the coil, the condensation pan, the blower, the blower motor, and both the return and supply plenums and is done entirely by hand. We are a very proud group of workers so please don't be surprised if while the cleaning is taking place your technician comes and asks you to look and see for yourself all of the debris he is finding and how clean your ducts look after his work is done.
