Maintaining clean heating, ventilation, and air conditioning (HVAC) systems is an important part of sustaining acceptable indoor air quality (IAQ). When an HVAC system is a source of contaminants introduced into occupied spaces, properly performed system cleaning services should take place to reduce or eliminate contaminant introduction.
On the day of your HVAC cleaning our systems cleaning specialist will arrive at your home at the scheduled time and begin familiarization with your HVAC system. The HVAC system is then shut down and the blower motor is removed for cleaning. The next step in the process is to stage our equipment and HEPA filtered collection device in the furnace area. Once in place the technician will connect the collection device directly to the “supply” trunk of HVAC system which will create a negative pressure throughout the duct system. Next, all but one of the supply and return grills in your home will be closed or covered with a grill mask to maximize the vacuum effect.
While the vacuum draws air through the system, positive air pressure devices are inserted into the supply branches to dislodge any debris that might be adhered to interior surfaces. Any debris then travels down the supply branch and into main trunk then pulled into our collection device. While the supply grills are removed, they are HEPA vacuumed to remove unwanted dirt, dust, and debris. After all supply branches are cleaned and the grills replaced, the main trunk is cleaned using positive pressure and agitation tools. Once the “supply” side of system is cleaned the tech then connects the collection device to the “return” side of the system and the process is repeated.
Once the supply and return trunk are clean we then access and clean the furnace’s heating and cooling components. Once all access holes are sealed and the system re-started, your HVAC system has been restored to the high standards set by Sinclaire Enterprises.
Duct Cleaning FAQs
Are there any health benefits that come from HVAC cleaning?
Heating, ventilation, and air conditioning (HVAC) systems have been shown to act as a collection source for a variety of contaminants that have a potential to affect health, such as mold, fungi, bacteria, and very small particles of dust. The removal of such contaminants from the HVAC system and home should be considered as one component in an overall plan to improve indoor air quality.
Will HVAC system cleaning reduce our home energy bills?
Research suggests that cleaning heating and cooling system components (e.g., cooling coils, fans and heat exchangers) maintains the energy efficiency of your system, resulting in a longer operating life, as well as maintenance cost savings. Clean, efficient systems are less likely to break down, have a longer life span, and generally operate more effectively than dirty systems.
What is a normal price range for the air duct cleaning service?
The Environmental Protection Agency says that duct cleaning services typically-but not always-range in cost from $450 to $1000 per heating and cooling system, depending on the services offered, the size of the system to be cleaned, system accessibility, climactic region, and level of contamination and type of duct material.
How long should it take to clean a typical residential HVAC system?
There are a variety of factors that could affect the time needed to clean an HVAC system, including the type of home, accessibility of the ductwork, and the number of workers on the project. A typical three- or four-bedroom home will require 4 to 8 hours for cleaning.
