Multiple times a day, the air in your home is circulated through the HVAC heating and cooling system installed, carrying along with it copious amounts of visible, as well as invisible, air-borne dust and debris.
Over time, aided and abetted by neglect and poor installation work, a part of this everyday dust and other contaminants that managed to sneak past the furnace filters, gets accumulated in the ducts, and reduces the efficiency of your system.
Effects of grimy ducts
Although it has not been scientifically proven yet that a build-up of grime in your ventilation duct system poses health hazards as such, experts recommend cleaning up your air ducts once every three to five years. You might usually want to hire a professional HVAC repair and maintenance company do the cleaning services, which they usually charge at around $300 to $500 for a full clean-up.
Lately, builders have increasingly focused on insulation and energy conservation. As a result, air duct system if kept without maintenance for long stretches of time can become stale and mold-infested, which can be mildly discomforting, especially if the inhabitants are prone to allergic reactions from debris floating in the air. Thus for those with sensitive adenoidal functions, investing a couple hundred bucks in a duct-cleaning project shouldn’t be much of an annoyance.
Do it yourself
Before you pick up your phone, there are some easy tips for an elementary duct-cleaning exercise. Simply detach the floor register or the furnace filter, insert a vacuum cleaner hose into the duct, and vroom it around for a bit. When you’re done, if you can still spot coats of dust and grime beyond the reach of your cleaning hose, it’d be advisable to call in the pros.
Symptoms of an unclean duct
Once in a while, after a period of heavy and constant temperature moderation, especially after the warm and cold months, all duct entrances should be examined to ascertain the level of contamination inside. The following symptoms are indicative of significant indoor pollution:-
- Visible particulates blowing out of your surface filters and registers.
- Clogged dust and grime, entangled with hair and cobwebs.
- Rodent/Insect droppings/corpses.
- Mold.In addition, experts say any recent re-modelling or nearby construction activities are sure to contribute unwanted dust into your ventilation system.
Thus we have seen the various scenarios which might warrant a call to your nearest maintenance guy.
Reasons to skip
One might also seek to consider the possible scenarios in which the clean up process is simply un-necessary, and also in order to save those valuable 300-odd bucks.
- No verifiable or proven health benefits.
- Grime already accumulated and settled in your duct system is probably not circulating in the air.
- Cleaning or changing the surface filters regularly usually does the job, as they trap all the visible culprits anyway.
Methods of duct cleaning
- Portable hand held vacuuming
- Mechanical brushing
- Air sweeping, the most effective, as well as costly, process.
Getting the air ducts cleaned once every couple of years does a decent job of maintaining your domestic air purity. Certain agencies insist on annual air-duct cleaning jobs, citing unverifiable health hazard claims, but it is probably going a bit overboard.
Exercising a certain flair of prudence and domestic caution can go a long way in keeping your ducts clean, and the air in your home dust-free. Sometimes it’s best to simply hire a professional company to do, and I would like to take this time to recommend chauffage montreal by Climatisation Davis, an air conditioning company in Montreal.
