The actual process of cleaning the vents would be impossible with the evaluation of the workload. That is an important process that can determine whether the work will go smoothly or not. This is also a good way to discern between good and bad cleaning company (in case you didn’t hire us). A business that is out there just for money will pay little attention to the estimation of the workload and thus they will not be as good as it should be.
This post is an explanation as well as a set of guidelines that a real and honest contractor will follow. If you notice that your contractor isn’t following these, then you should look for another one.
Some basic guidelines we follow
The NADCA specifications about cleaning are the law in this business, and every decent company should follow them. They are created by people who understand the necessity of the clean air ducts and some of them are environmental consultants and project engineers. Those specifications contain many relevant facts including the area that have to be cleaned, sectors that are susceptible to mold, documents a contractor needs to have and so on.
Every entrepreneur, including us, will send an evaluator who will ask for mechanical blueprints of the HVAC system. The design will give us an idea of what we need to use to clean the system properly. It also gives us an insight into spots that may gather dust which isn’t easily cleaned. If an evaluator doesn’t ask for a blueprint, then his employer has no intention to do the assignment properly.
The said plans are only the beginning of the evaluation as they represent a map and a list of all significant parts of the HVAC system. The estimation of the workload starts only after our assessment officer reviews those mechanical blueprints. Once he does that he can go and start breaking down the system in areas and he can start locating those parts. The parts in question include, among the others, coils, registers, grills, air handlers and so on.
How do we determine the fee for the cleaning?
The cost for the job isn’t same for everyone as that would be unfair for people. You can ask our employees to explain you in detail about what you pay and why the price is like that. The charge consists of three parts, the pay for the number of man hours, the consumables and other miscellaneous things. Man hours represent the number of hours it will take to clean everything while consumables charge represents the amo8unt of chemicals and other materials we will have to spend. Miscellaneous charges represent the costs of transport as well as the cost of additional work like installation of electrical pigtails and so on.
