WHAT IS AIR DUCT CLEANING?
The Environmental Protection Agency (EPA) defines AIR DUCT CLEANING as:
…the cleaning of various heating and cooling system components of forced air systems, including the supply and return air ducts and registers, grilles and diffusers, heat exchangers heating and cooling coils, condensate drain pans (drip pans), fan motor and fan housing, and the air handling unit housing.
During cleaning, the entire HVAC system is placed under continuous negative pressure (with a vacuum) to prevent the spread of contaminants.
Continuous negative pressure allows very fine particles to be removed from the system as they become airborne, ensuring that these particles are not released into the living space when the system is turned on after cleaning.
This negative pressure also serves to extract the loosened contaminants, which are collected and removed from your home.
Often HVAC system components collect significant amounts of debris and particulate during construction activities within a building. NADCA recommends that newly installed HVAC systems or HVAC systems undergoing renovation be verified clean, and protected before the system is permitted to operate.
WHAT IS AEROSEAL DUCT SEALING?
In houses with forced-air heating and cooling systems, ducts are used to distribute conditioned air throughout the house. In a typical house, however, about 20 to 30 percent of the air that moves through the duct system is lost due to leaks, holes, and poorly connected ducts. The result is higher utility bills and difficulty keeping the house comfortable, no matter how the thermostat is set.
How do you know that your home has poorly performing ducts?
You have high summer and winter utility bills;
You have rooms that are difficult to heat and cool;
You have stuffy rooms that never seem to feel comfortable;
Your ducts are located in an attic, crawlspace, or the garage;
You find tangled or kinked flexible ducts in your system.
