To ensure the HVAC system runs with its full capacity, regular inspections are a must. There is no better time than today for checking the air ducts and ensure everything is tip-top.
You wouldn’t want your Commercial HVAC or residential central ac unit to get infested with molds and then bear the costs of mold removal. Besides, the AC Replacement or duct replacement costs are too high. That’s why to avoid the air duct cleaning cost and Commercial HVAC system replacement or HVAC installation expenses, it is best to keep a clean sheet with the current state of the HVAC system.
The entire inspection process can be divided into several steps to ease up the process. If the inspection area is too big, several inspectors can be appointed.
Inspectors and how they should be used to inspect a big facility
In case you are running a big facility with Commercial HVAC systems acting as a central air conditioning units, then you will need more than one in-charge or responsible person to physically check everything or oversee the entire inspection process done by junior employees who will report back the details and the current state of the air conditioning units.
Depending on the size of the facility and the number of HVAC system installed, the in-charge inspectors can be deployed in two ways.
- One inspection in-charge – One inspection location
- One inspection in-charge – several inspection locations
Let me explain these two in details.
One Inspection in-charge – One inspection location
This type of approach is taken when a single person is equipped to check an entire system in a single location.
For example, if the facility is a gadget assembly workshop, then this type of approach can be taken to regularly check each department of the facility. Say, the facility has one assembly department, a painting department, a quality control department, and a packaging department. So, there can be 4 different inspection in-charge who can handle the close inspection of the HVAC system installed in each department.
The end result being – 4 individual inspectors who are equipped to check the entire HVAC system including the duct, the Gas Furnaces, The condensers, etc. But for this case, each inspector must be capable to handle, understand and inspect each aspect of the air conditioning units.
One inspection in-charge – several inspection locations
This type of approach is suitable if the air conditioning units are very sensitive i.e. any minor misalignment or accidental adjustment can heavily affect the performance of the HVAC system. So, to inspect them properly, the inspector should be someone who is very familiar with a certain part of the HVAC system.
In this case, the inspectors will check the entire facility but only a specific part of the HVAC system. So, one inspector will be in charge of handling a certain part of the HVAC system throughout the whole facility. And another (or several inspectors) will be in charge of other parts.
Now, let’s talk about the inspection process for HVAC Systems.
Check the material of air ducts
If the air ducts aren’t made of the right material, there is a high chance that you are paying more in electric bills that you should.
And as for the right material, sheet metal, flexible aluminum, fiberglass are some of the most appropriate and suitable material. They are suitable for transporting the air from one place to the other inside the facility or building.
Also, if your system utilizes the spaces between the floor and rafters joists as the makeshift ductwork, you are wasting electrical energy and paying more.
Sealing the leaks in ductwork
This is an important aspect of the inspection process – checking the connections of the air ducts.
Sometimes, the air duct connections become loose, they start to gaps in the seam, or they could be torn apart, even a split count.
When these happen, the air that was supposed to reach the final destination, it leaks out of the ducts. As a result, you don’t get the airflow you are supposed to receive at the end. These leaks should be patched as soon as possible to ensure the efficiency of the air conditioning units.
Supports holding the air ducts
The support for the air duct is a must, especially if the ducts are suspended above a ceiling. If the supports become loose or break apart, the air transportation chain is broken and in worst-case scenario, the air duct can even cause a serious injury to the people walking beneath or to the assets.
Covering up and insulations
Insulation is a key addition to the air ducts. The importance of insulation lies on keeping the heating and cooling in balance. In simpler words, this insulation works as a barrier for the air ducts so that the air temperature inside the ducts (air that flows inside it) is not altered by any external heating and cooling solution.
Another covering that is equally important for air ducts is acoustic lining. This lining works to suppress the sound that the flowing air inside the air ducts makes.
If these coverings are not well-built with the air ducts, serious lacking in performance can be noticed.
Look for molds in the air ducts
Molds in duct is a pretty much common. And as I have mentioned earlier, the expenses of mold removal is not something you can bear very often. So, the best way to avoid these kinds of infestation is by identifying the treats beforehand. That’s why, in the inspection process, try to look for even the minimum amount of mold in the AC units because this small amount of mold gathered in the system will soon turn to be a headache for you. So, best is to eliminate them from the bottom.
Now, if you or your team doesn’t feel comfortable inspecting the above-ceiling ductwork, let someone with professional experience to handle the job.
