A HVAC system which has not been properly installed or maintained can eventually become a major liability for your property. Air ducts are prone to pollen, dust, and debris build-up which may affect the performance of the system, and possibly affect the health of the residents of the building due to spores escaping into the air and causing allergic reactions.
While you shouldn’t become paranoid about having a HVAC technician clean your air ducts (air contaminants can come from virtually anywhere after all), there are certain physical signs that could suggest you are in need of an AC duct cleaning, whether it be a solar air conditioner, ducted system, or split AC. These signs include: visible mold growth on the ducts and other components of the system, signs of rodent, insect, or other vermin infestation, vents are clogged with debris or dust, or there are particles floating around which obviously come from the AC system.
So how do you go about finding a reliable duct cleaning business in Dubai? A good rule of thumb is to first scratch the companies off your list who make a big song and dance about the health benefits of cleaning AC ducting, and tell you that every company should make it a monthly priority. While it’s a good idea if you notice any of the signs listed above there are absolutely no studies proving that AC ducts have been solely responsible for any health problems. This is most likely due to the fact that it’s impossible to rule out contaminants from other sources.
When you are requesting a quote the company will visit your premises to determine the level of service you will need. While they are there check that they have experience with your type of duct, especially if it’s flexible duct as this type requires extra care and attention to prevent punctures. While they are examining the system ask them for evidence of the contamination that warrants a cleaning of the duct. If no evidence is forthcoming, then it’s unlikely your system’s ducts are in need of cleaning at that time.
If any of the companies you are considering using make use of biocides or other chemicals, find out the various pros and cons of each so you can make an informed decision. Chemicals which inhibit mold and mildew growth, kill bacteria, and protect against rust are a good idea – but not at the expense of the environment.
Always ask for references for any air duct cleaning. You should also make a point of checking up on the references so you know they are not fake. If you look hard enough you will always find a few dissatisfied customers for any company - it’s just people being people, but a prevalence of unsatisfied versus satisfied should have you looking elsewhere. You can also follow up a reference check with a quick call to the Better Business Bureau to see if any complaints have been lodged against the company.
Of course, it’s always in your best interests to check the licensing of any companies you are going to do business with. Licenses expire so make sure everything is up to date and that they are relevant for what you require. And finally, get a signed written agreement from the company outlining all of the work you are commissioning and paying them for. This should include the time to do the job, the tasks they will be performing, materials used, and interruptions that may occur while the work is being carried out.
