My name is Ron Nichols and I am the owner of CMR air duct cleaning located in Raleigh NC. We are a full service air duct, ventilation and HVAC cleaning company. We currently serve North Carolina, South Carolina and Virginia. Our company is also partners with a national mold remediation company that allows us to service the entire USA. We have multiple crews that service everything from residential to industrial and commercial air duct and ventilation cleaning.
We wanted to write this article on the parts, components, questions and discussions of the HVAC system when we clean it. This is the standard in our industry and these steps must be taken to insure the ductwork and air handlers our cleaned properly. When your having this service done its important to make sure your contractor is cleaning everything we are getting ready to discuss.
Is the company your hiring to clean the HVAC system a member of the Nation Air Duct Cleaners Association? Also can they show proof they are members of NADCA?
This is very important because this is the only association out there that sets the standards for the industry. There are also a lot of companys that claim to be members and they are not. With that said make them show you proof or go to www.nadca.com and look up there membership there.
Before starting the cleaning process its important to do a complete inspection of the HVAC system before cleaning. If there are any problems with the system the contractor needs to disclose this to the property owner. This is also a great time to track down the source of a problem the owner or manager may have. Our company does a lot of mold remediation in HVAC systems and this is a critical step in our process. We can remediate the mold but you have to find the source so ot doesn’t come back.
A standard residential house has supply ductwork and return ductwork. The supply ductwork is the vents that blow air out and the return ductwork is the vents where you put your filters. Commercial HVAC systems sometimes have fresh air intake and that brings in outdoor air through ductwork. All of the ductwork should be checked in random areas to insure it clean. If the air duct is fiberboard or fiberglass lined the air duct cleaning company should check to make sure it is in good condition.
All of the registers and grills should be cleaned and visibly clear of contaminates. These should also be attached and set correctly to the air duct.
Also associated with the air ducts is plenum boxes. These are chambers in which the air is distributed through duct to each room. These should also be clean and free of visible duct dirt bugs and moisture.
One of the steps in the cleaning process is to attach a negative air machine to the HVAC unit. This can sometimes involve cutting a access hole in the ductwork or disconnecting a air duct. You need to make this is properly sealed up correctly. The standard for properly sealing air ducts and sheetmetal in ductwork can be found in the NADCA ACR Standard.
There are a lot of different types of HVAC units on the market today. Some of the common names people call them is furnace, air handler, air conditioner, and heater etc. They all have a blower in them. This is the part that forces the air out of the vents. This should also be removed and cleaned and visible free of debris mold etc.
Right beside the blower you will have a coil. The coil looks like a radiator. This is a part of the system that heats or cools or does both. The coil should also be cleaned. Its important that the coil is cleaned on the supply side and the return side.
After the system is cleaned it’s a good idea to replace all of your filters. You will then have a fresh new start!
The main reason I wrote this article is for our customers and consumers to understand its important to clean the entire system. If you don’t clean certain parts of the HVAC system then as soon as you turn the system on you can contaminate what was just cleaned. A good air duct cleaning company will give you a firm price out the door for the entire system. That price should include all the air ducts and air handlers. Our company also throws in a free dryer vent cleaning with the purchase of a air duct cleaning job.
